Fetal Growth Retardation
Exposure of the female parent, human or animal, to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals that may affect offspring. It includes pre-conception maternal exposure.
Intensive Care Units, Neonatal
Studies in which subsets of a defined population are identified. These groups may or may not be exposed to factors hypothesized to influence the probability of the occurrence of a particular disease or other outcome. Cohorts are defined populations which, as a whole, are followed in an attempt to determine distinguishing subgroup characteristics.
Prenatal Exposure Delayed Effects
A condition of fetal overgrowth leading to a large-for-gestational-age FETUS. It is defined as BIRTH WEIGHT greater than 4,000 grams or above the 90th percentile for population and sex-specific growth curves. It is commonly seen in GESTATIONAL DIABETES; PROLONGED PREGNANCY; and pregnancies complicated by pre-existing diabetes mellitus.
A method, developed by Dr. Virginia Apgar, to evaluate a newborn's adjustment to extrauterine life. Five items - heart rate, respiratory effort, muscle tone, reflex irritability, and color - are evaluated 60 seconds after birth and again five minutes later on a scale from 0-2, 0 being the lowest, 2 being normal. The five numbers are added for the Apgar score. A score of 0-3 represents severe distress, 4-7 indicates moderate distress, and a score of 7-10 predicts an absence of difficulty in adjusting to extrauterine life.
A chronic lung disease developed after OXYGEN INHALATION THERAPY or mechanical ventilation (VENTILATION, MECHANICAL) usually occurring in certain premature infants (INFANT, PREMATURE) or newborn infants with respiratory distress syndrome (RESPIRATORY DISTRESS SYNDROME, NEWBORN). Histologically, it is characterized by the unusual abnormalities of the bronchioles, such as METAPLASIA, decrease in alveolar number, and formation of CYSTS.
Body Mass Index
An indicator of body density as determined by the relationship of BODY WEIGHT to BODY HEIGHT. BMI=weight (kg)/height squared (m2). BMI correlates with body fat (ADIPOSE TISSUE). Their relationship varies with age and gender. For adults, BMI falls into these categories: below 18.5 (underweight); 18.5-24.9 (normal); 25.0-29.9 (overweight); 30.0 and above (obese).

Retinopathy of Prematurity
A bilateral retinopathy occurring in premature infants treated with excessively high concentrations of oxygen, characterized by vascular dilatation, proliferation, and tortuosity, edema, and retinal detachment, with ultimate conversion of the retina into a fibrous mass that can be seen as a dense retrolental membrane. Usually growth of the eye is arrested and may result in microophthalmia, and blindness may occur. (Dorland, 27th ed)
Procedures for finding the mathematical function which best describes the relationship between a dependent variable and one or more independent variables. In linear regression (see LINEAR MODELS) the relationship is constrained to be a straight line and LEAST-SQUARES ANALYSIS is used to determine the best fit. In logistic regression (see LOGISTIC MODELS) the dependent variable is qualitative rather than continuously variable and LIKELIHOOD FUNCTIONS are used to find the best relationship. In multiple regression, the dependent variable is considered to depend on more than a single independent variable.
Infant, Newborn, Diseases
Diseases of newborn infants present at birth (congenital) or developing within the first month of birth. It does not include hereditary diseases not manifesting at birth or within the first 30 days of life nor does it include inborn errors of metabolism. Both HEREDITARY DISEASES and METABOLISM, INBORN ERRORS are available as general concepts.
Disorders in which there is a delay in development based on that expected for a given age level or stage of development. These impairments or disabilities originate before age 18, may be expected to continue indefinitely, and constitute a substantial impairment. Biological and nonbiological factors are involved in these disorders. (From American Psychiatric Glossary, 6th ed)
Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.
A status with BODY WEIGHT that is grossly above the acceptable or desirable weight, usually due to accumulation of excess FATS in the body. The standards may vary with age, sex, genetic or cultural background. In the BODY MASS INDEX, a BMI greater than 30.0 kg/m2 is considered obese, and a BMI greater than 40.0 kg/m2 is considered morbidly obese (MORBID OBESITY).

Maternal Nutritional Physiological Phenomena
Multiple Birth Offspring
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
Intensive Care, Neonatal
Statistical models which describe the relationship between a qualitative dependent variable (that is, one which can take only certain discrete values, such as the presence or absence of a disease) and an independent variable. A common application is in epidemiology for estimating an individual's risk (probability of a disease) as a function of a given risk factor.

Age as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or the effect of a circumstance. It is used with human or animal concepts but should be differentiated from AGING, a physiological process, and TIME FACTORS which refers only to the passage of time.
The ratio of two odds. The exposure-odds ratio for case control data is the ratio of the odds in favor of exposure among cases to the odds in favor of exposure among noncases. The disease-odds ratio for a cohort or cross section is the ratio of the odds in favor of disease among the exposed to the odds in favor of disease among the unexposed. The prevalence-odds ratio refers to an odds ratio derived cross-sectionally from studies of prevalent cases.
Obstetric Labor Complications
Maleness or femaleness as a constituent element or influence contributing to the production of a result. It may be applicable to the cause or effect of a circumstance. It is used with human or animal concepts but should be differentiated from SEX CHARACTERISTICS, anatomical or physiological manifestations of sex, and from SEX DISTRIBUTION, the number of males and females in given circumstances.
Studies which start with the identification of persons with a disease of interest and a control (comparison, referent) group without the disease. The relationship of an attribute to the disease is examined by comparing diseased and non-diseased persons with regard to the frequency or levels of the attribute in each group.
Pregnancy Complications, Infectious
Respiratory Distress Syndrome, Newborn
A condition of the newborn marked by DYSPNEA with CYANOSIS, heralded by such prodromal signs as dilatation of the alae nasi, expiratory grunt, and retraction of the suprasternal notch or costal margins, mostly frequently occurring in premature infants, children of diabetic mothers, and infants delivered by cesarean section, and sometimes with no apparent predisposing cause.

Degeneration of white matter adjacent to the CEREBRAL VENTRICLES following cerebral hypoxia or BRAIN ISCHEMIA in neonates. The condition primarily affects white matter in the perfusion zone between superficial and deep branches of the MIDDLE CEREBRAL ARTERY. Clinical manifestations include VISION DISORDERS; CEREBRAL PALSY; PARAPLEGIA; SEIZURES; and cognitive disorders. (From Adams et al., Principles of Neurology, 6th ed, p1021; Joynt, Clinical Neurology, 1997, Ch4, pp30-1)
Pregnancy in Diabetics
A status with BODY WEIGHT that is above certain standard of acceptable or desirable weight. In the scale of BODY MASS INDEX, overweight is defined as having a BMI of 25.0-29.9 kg/m2. Overweight may or may not be due to increases in body fat (ADIPOSE TISSUE), hence overweight does not equal "over fat".
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.

A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).

Confounding Factors (Epidemiology)
Factors that can cause or prevent the outcome of interest, are not intermediate variables, and are not associated with the factor(s) under investigation. They give rise to situations in which the effects of two processes are not separated, or the contribution of causal factors cannot be separated, or the measure of the effect of exposure or risk is distorted because of its association with other factors influencing the outcome of the study.

Pregnancy Complications, Cardiovascular
Pregnancy Trimester, First
A complication of PREGNANCY, characterized by a complex of symptoms including maternal HYPERTENSION and PROTEINURIA with or without pathological EDEMA. Symptoms may range between mild and severe. Pre-eclampsia usually occurs after the 20th week of gestation, but may develop before this time in the presence of trophoblastic disease.
Diabetes mellitus induced by PREGNANCY but resolved at the end of pregnancy. It does not include previously diagnosed diabetics who become pregnant (PREGNANCY IN DIABETICS). Gestational diabetes usually develops in late pregnancy when insulin antagonistic hormones peaks leading to INSULIN RESISTANCE; GLUCOSE INTOLERANCE; and HYPERGLYCEMIA.
Specialized connective tissue composed of fat cells (ADIPOCYTES). It is the site of stored FATS, usually in the form of TRIGLYCERIDES. In mammals, there are two types of adipose tissue, the WHITE FAT and the BROWN FAT. Their relative distributions vary in different species with most adipose tissue being white.

Conditions characterized by a significant discrepancy between an individual's perceived level of intellect and their ability to acquire new language and other cognitive skills. These disorders may result from organic or psychological conditions. Relatively common subtypes include DYSLEXIA, DYSCALCULIA, and DYSGRAPHIA.
Obstetric and neonatal outcome following chronic hypertension in pregnancy among different ethnic groups. (1/4769)We retrospectively studied pre-eclampsia rate and obstetric outcome in a cohort of 436 pregnancies amongst 318 women of different ethnic backgrounds attending an antenatal hypertension clinic from 1980-1997, identifying 152 women (213 pregnancies) with chronic essential hypertension. The ethnic breakdown was: White, 64 (30.0%) pregnancies in 48 (31.5%) women; Black/Afro-Caribbean, 79 (37.1%) pregnancies in 56 (36.8%) women; and Indo-Asians, 70 (32.3%) pregnancies in 48 (31.6%) women. The prevalences of pre-eclampsia in White, Black and Indo-Asian women were 17.2%, 12.7% and 18.6%, respectively (p = 0.58). Pregnancies of Indo-Asian women were of shorter gestation, and babies in this group also had lower birth weight and ponderal index compared to those of White and Black women (all p < 0.05). The proportions of overall perinatal mortality were 1.6% for Whites (1/64), 3.8% for Blacks (3/79) and 10.0% for Indo-Asians (7/70), suggesting increased risk in the Indo-Asian group. Indo-Asian women with chronic essential hypertension need careful antenatal care and observation during pregnancy. (+info)
Precocious estrus and reproductive ability induced by PG 600 in prepuberal gilts. (2/4769)A total of 29 SPF Large White prepuberal gilts (mean age 152 days at treatment) were examined for estrous and ovulatory responses after PG 600 treatment. After treatment, 85.2% of the gilts showed standing estrus within 6 days. Whereas the treatment-to-estrus interval and duration were 3.7 and 1.9 days respectively. As ovulation occurred on Day 5 to 6, appropriate timing of artificial insemination would be about 4 days after treatment. Fertility of gilts revealed to be excellent, giving rise to a high percentage of normal embryos, 85.3%. Meanwhile, development and growth of fetuses were mostly normal. Other reproductive performances recorded were: mean litter size 6.8; mean birth weight 1.26 kg; weaning-to-return estrus interval 5 to 8 days. In conclusion, PG 600 was found to be useful in inducing fertile estrus in prepuberal gilts, a result which will be of interest for commercial pig farms. (+info)
Role of intergenerational effects on linear growth. (3/4769)Current knowledge on the role of intergenerational effects on linear growth is reviewed on the basis of a literature search and recent findings from an ongoing study in Guatemala. Fourteen studies were identified, most of which examined the intergenerational relationships in birth weight. Overall, for every 100 g increase in maternal birth weight, her child's birth weight increased by 10-20 g. The study samples were primarily from developed countries, and birth weight data were extracted from hospital records and/or birth registries. Among the few studies that examined associations between the adult heights of parents and their offspring, correlation coefficients of 0.42-0.5 were reported. None of the studies examined intergenerational relationships in birth length or linear growth patterns during early childhood, preadolescence and/or adolescence. Prospectively collected data from long-term studies being carried out in rural Guatemala provide the first evidence of intergenerational relationships in birth size in a developing country setting. Data were available for 215 mother-child pairs. Maternal birth size was a significant predictor (P < 0.05) of child's birth size after adjusting for gestational age and sex of the child and other potential confounders. Child's birth weight increased by 29 g/100 g increase in maternal birth weight which is nearly twice that reported in developed countries. Similarly, child's birth length increased by 0.2 cm for every 1 cm increase in mother's birth length. The effect of maternal birth weight remained significant even after adjusting for maternal adult size. More evidence from developing countries will help explain the underlying mechanisms and identify appropriate interventions to prevent growth retardation. (+info)
Low-weight neonatal survival paradox in the Czech Republic. (4/4769)Analysis of vital statistics for the Czech Republic between 1986 and 1993, including 3,254 infant deaths from 350,978 first births to married and single women who conceived at ages 18-29 years, revealed a neonatal survival advantage for low-weight infants born to disadvantaged (single, less educated) women, particularly for deaths from congenital anomalies. This advantage largely disappeared after the neonatal period. The same patterns have been observed for low-weight infants born to black women in the United States. Since the Czech Republic had an ethnically homogenous population, virtually universal prenatal care, and uniform institutional conditions for delivery, Czech results must be attributed to social rather than to biologic or medical circumstances. This strengthens the contention that in the United States, the black neonatal survival paradox may be due as much to race-related social stigmatization and consequent disadvantage as to any hypothesized hereditary influences on birth-weight-specific survival.

Management of breast cancer during pregnancy using a standardized protocol. (5/4769)PURPOSE: No standardized therapeutic interventions have been reported for patients diagnosed with breast cancer during pregnancy. Of the potential interventions, none have been prospectively evaluated for treatment efficacy in the mother or safety for the fetus. We present our experience with the use of combination chemotherapy for breast cancer during pregnancy. PATIENTS AND METHODS: During the past 8 years, 24 pregnant patients with primary or recurrent cancer of the breast were managed by outpatient chemotherapy, surgery, or surgery plus radiation therapy, as clinically indicated. The chemotherapy included fluorouracil (1,000 mg/m2), doxorubicin (50 mg/m2), and cyclophosphamide (500 mg/m2), administered every 3 to 4 weeks after the first trimester of pregnancy. Care was provided by medical oncologists, breast surgeons, and perinatal obstetricians. RESULTS: Modified radical mastectomy was performed in 18 of the 22 patients, and two patients were treated with segmental mastectomy with postpartum radiation therapy. This group included patients in all trimesters of pregnancy. The patients received a median of four cycles of combination chemotherapy during pregnancy. No antepartum complications temporally attributable to systemic therapy were noted. The mean gestational age at delivery was 38 weeks. Apgar scores, birthweights, and immediate postpartum health were reported to be normal for all of the children. CONCLUSION: Breast cancer can be treated with chemotherapy during the second and third trimesters of pregnancy with minimal complications of labor and delivery. (+info)
Energy intake, not energy output, is a determinant of body size in infants. (6/4769)BACKGROUND: It has been proposed that the primary determinants of body weight at 1 y of age are genetic background, as represented by parental obesity, and low total energy expenditure. OBJECTIVE: The objective was to determine the relative contributions of genetic background and energy intake and expenditure as determinants of body weight at 1 y of age. DESIGN: Forty infants of obese and 38 infants of lean mothers, half boys and half girls, were assessed at 3 mo of age for 10 risk factors for obesity: sex, risk group (obese or nonobese mothers), maternal and paternal body mass index, body weight, feeding mode (breast, bottle, or both), 3-d energy intake, nutritive sucking behavior during a test meal, total energy expenditure, sleeping energy expenditure, and interactions among them. RESULTS: The only difference between risk groups at baseline was that the high-risk group sucked more vigorously during the test meal. Four measures accounted for 62% of the variability in weight at 12 mo: 3-mo weight (41%, P = 0.0001), nutritive sucking behavior (9%, P = 0.0002), 3-d food intake (8%, P = 0.0002), and male sex (3%, P = 0.05). Food intake and sucking behavior at 3 mo accounted for similar amounts of variability in weight-for-length, body fat, fat-free mass, and skinfold thickness at 12 mo. Contrary to expectations, neither total nor sleeping energy expenditure at 3 mo nor maternal obesity contributed to measures of body size at 12 mo. CONCLUSIONS: Energy intake contributes significantly to measures of body weight and composition at 1 y of age; parental obesity and energy expenditure do not. (+info)
Leucine metabolism in preterm infants receiving parenteral nutrition with medium-chain compared with long-chain triacylglycerol emulsions. (7/4769)BACKGROUND: Although medium-chain triacylglycerols (MCTs) may be utilized more efficiently than long-chain triacylglycerols (LCTs), their effect on protein metabolism remains controversial. OBJECTIVE: The aim of the study was to compare the effects of mixed MCT-LCT and pure LCT emulsions on leucine metabolism in preterm infants. DESIGN: Fourteen preterm [gestational age: 30+/-1 wk; birth weight: 1409+/-78 g (x +/- SE)] neonates were randomly assigned to receive, from the first day of life, either a 50:50 MCT-LCT (mixed MCT group; n = 7) or an LCT (LCT group; n = 7) lipid emulsion as part of an isonitrogenous, isoenergetic total parenteral nutrition program. On the fourth day, infants received intravenous feeding providing 3 g lipid, 15 g glucose, and 3 g amino acids kg(-1) x d(-1) and underwent 1) indirect calorimetry and 2) a primed, 2-h infusion of H13CO3Na to assess the recovery of 13C in breath, immediately followed by 3) a 3-h infusion of L-[1-13C]leucine. RESULTS: The respiratory quotient tended to be slightly but not significantly higher in the mixed MCT than in the LCT group (0.96+/-0.06 compared with 0.93+/-0.03). We did not detect a significant difference between the mixed MCT and LCT groups with regard to release of leucine from protein breakdown (B; 309+/-40 compared with 257+/-46 micromol x kg(-1) x h(-1)) and nonoxidative leucine disposal (NOLD; 296+/-36 compared with 285+/-49 micromol x kg(-1) x h(-1)). In contrast, leucine oxidation was greater in the mixed MCT than in the LCT group (113+/-10 compared with 67+/-10 micromol x kg(-1) x h(-1); P = 0.007). Net leucine balance (NOLD - B) was less positive in the mixed MCT than in the LCT group (-14+/-9 compared with 28+/-10 micromol x kg(-1) x h(-1); P = 0.011). CONCLUSION: Mixed MCTs may not be as effective as LCT-containing emulsions in promoting protein accretion in parenterally fed preterm neonates. (+info)
Accuracy of sonographic estimates of fetal weight in very small infants. (8/4769)OBJECTIVE: Fetal outcome is inversely related to gestational age and birth weight. Therefore, in very small fetuses, estimated weight may play an important role in clinical management. Our aim was to determine the accuracy of sonographic estimates of fetal weight in very small infants. DESIGN: Retrospective chart review. SUBJECTS: We retrospectively studied 100 consecutive infants with a birth weight of < 1000 g, at a gestational age between 24.0 and 34.0 weeks, in which biometric data < 2 weeks prior to delivery were available for analysis. METHODS: We estimated fetal weight with the use of two methods--by those of Hadlock and colleagues and Scott and colleagues--and compared the estimated values with measured birth weights. RESULTS: The infants had a mean birth weight of 742 +/- 173 (SD) g, at a gestational age of 28.1 +/- 2.0 (SD) weeks. With Hadlock's method, the mean estimated fetal weight (EFW) was 736 +/- 186 (SD) g, which was not significantly different from birth weight; the mean EFW error was 0.8 +/- 12.7 (SD) %. With Scott's method, the mean EFW was 780 +/- 185 (SD) g, which was significantly increased above birth weight; the mean EFW error was 5.7 +/- 12.5 (SD) %. The accuracy of the weight estimates was not significantly affected by the period between ultrasound examination and delivery if < 2 weeks, or by fetal growth restriction. CONCLUSION: In our population of small fetuses, Hadlock's estimates of fetal weight correlated well with measured birth weight, whereas Scott's method tended to overestimate. (+info)
Low Birth Weight and High Birth Weight Infants Are Both at an Increased Risk to Have Type 2 Diabetes Among Schoolchildren in...
In the present study, we analyzed the impact of birth weight on various metabolic phenotypes in a young cohort aged 6-18 years based on a nationwide screening program from 1992 to 1997. We first confirmed a U-shaped relation between birth weight and the risk of type 2 diabetes, which was originally demonstrated in children and young adults in a study of Pima Indians (28). In the type 2 diabetic subjects born with high birth weight, blood pressure was higher, BMI was greater, and the incidence of positive family history of diabetes was higher than in those born with low birth weight, indicating a possibility of a different pathogenesis of type 2 diabetes in subjects with low and high birth weight. The constellation of diabetes, obesity, and high blood pressure, collectively termed metabolic syndrome, was more frequently observed in the subjects born with high birth weight.. The discovery that childhood type 2 diabetes is associated with obesity in the present study was consistent with previous ...
Both Low and High Birth Weight Linked to Fatty Liver Disease in Children | Lurie Childrens
A study published in the Journal of Pediatrics suggests that children born with lower or higher weight than normal may be at increased risk for developing nonalcoholic fatty liver disease (NAFLD). These children also were at higher risk for more severe disease but in different ways. Advanced scarring of the liver was associated with low birth weight, while more inflammation was linked to high birth weight. The study is the first to characterize the relationship between high birth weight and NAFLD.. With the obesity epidemic, we are seeing more babies with high birth weight than ever before, said co-author Mark Fishbein, MD, from Stanley Manne Childrens Research Institute at Ann & Robert H. Lurie Childrens Hospital of Chicago. Our study shows that these kids are more likely to have serious liver damage by the time they are teenagers.. NAFLD affects up to 25 percent of the U.S. population, according to the American Liver Foundation. It is the most common cause of chronic liver disease in ...
Is body size at birth related to circadian salivary cortisol levels in adulthood? : Results from a longitudinal cohort study
BACKGROUND: The hypothesis of fetal origins of adult disease has during the last decades received interest as an explanation of chronic, e.g. cardiovascular, disease in adulthood stemming from fetal environmental conditions. Early programming and enduring dysregulations of the hypothalamic-pituitary-adrenal (HPA axis), with cortisol as its end product, has been proposed as a possible mechanism by which birth weight influence later health status. However, the fetal origin of the adult cortisol regulation has been insufficiently studied. The present study aims to examine if body size at birth is related to circadian cortisol levels at 43 years. METHODS: Participants were drawn from a prospective cohort study (n = 752, 74.5%). Salivary cortisol samples were collected at four times during one day at 43 years, and information on birth size was collected retrospectively from delivery records. Information on body mass during adolescence and adulthood and on health behavior, medication and medical ...
Estimating the Effect of Smoking on Birth Weight in a Dynamic Model when Fertility is a Choice
The negative effect of smoking during a pregnancy on a childs birth weight outcome has been a consistent finding in the economics literature on estimating birth weight production functions. An important result in the literature is that the negative effect of smoking on birth weight is generally robust to the introduction of unobserved heterogeneity in family-specific health endowments. All of the studies have assumed, however, that fertility itself is unrelated to either anticipated or realized birth weight outcomes that depend on such endowments. One purpose of this paper is to explore the impact of relaxing that assumption on the estimates of the smoking effect on birth weight. To that end, a dynamic model of fertility choice that explicitly incorporates the smoking decision, allowing for its addictive nature, and the birth weight technology, is constructed and empirically implemented using longitudinal data from the National Longitudinal Surveys 1979 youth cohort. In addition to obtaining estimates

Weight in the first year of life: associations with maternal prepregnancy body mass index and gestational weight gain-findings...
Objective To investigate the obesogenic influence of maternal prepregnancy body mass index (BMI) and gestational weight gain (GWG) on infant weight at birth and 12 months postpartum in an Australian general population sample. Methods Data on 1,305 pregnant women were collected on prepregnancy BMI and GWG through maternal interview, on infant weight at birth through hospital records, and on infant weight 12 months postbirth through direct measurement. Relationships between prepregnancy, gestational weight exposures, and infant weight outcomes were assessed with and without adjustment for potential confounding. Results We observed a 14 to 24 g increase in infant birth weight for every 1 kg increase in maternal weight (infant birth weight: β(BMI) = 0.014, p , 0.000; β(GWG) = 0.012, p , 0.000; and 12 months: β(BMI) = 0.018, p , 0.000; β(GWG) = 0.024, p , 0.000). Effects remained after adjustment for potential confounders (infant birth weight: β(BMI) = 0.014, p , 0.000; β(GWG) = 0.012, p , ...
Bergen Open Research Archive: Assfociations of perfluoroalkyl substances (PFAS) with lower birth weight: An evaluation of...
Background: Prenatal exposure to perfluoroalkyl substances (PFAS) has been associated with lower birth weight in epidemiologic studies. This association could be attributable to glomerular filtration rate (GFR), which is related to PFAS concentration and birth weight. Objectives: We used a physiologically based pharmacokinetic (PBPK) model of pregnancy to assess how much of the PFAS-birth weight association observed in epidemiologic studies might be attributable to GFR. Methods: We modified a PBPK model to reflect the association of GFR with birth weight (estimated from three studies of GFR and birth weight) and used it to simulate PFAS concentrations in maternal and cord plasma. The model was run 250,000 times, with variation in parameters, to simulate a population. Simulated data were analyzed to evaluate the association between PFAS levels and birth weight due to GFR. We compared simulated estimates with those from a meta-analysis of epidemiologic data. Results: The reduction in birth weight ...
Birth weight, body mass index and asthma in young adults | Thorax
We have shown that a lower birth weight and a higher BMI in adult life were associated with a higher prevalence of asthma and wheeze among individuals in a national birth cohort studied at 26 years of age. The association with BMI was stronger in women.. The association with lower birth weight, after controlling for gestational age, suggests that impaired fetal growth is a determinant of adult asthma. In older adults lower birth weight is associated with lower lung function, a relation which is likely to be explained by impaired fetal airway growth leading to suboptimal airway calibre in adult life.29 We believe that small airway size is also likely to explain the association between lower birth weight and asthma. It seems plausible that, for a given degree of atopy and bronchial hyperreactivity, a young adult with smaller airways would be more likely to experience asthma symptoms. It seems less likely that the association between lower birth weight and asthma is explained by a higher prevalence ...
Is low birth weight a risk factor for asthma during adolescence? | Archives of Disease in Childhood
The effect of low birth weight on the incidence of asthma by 17 years of age was investigated by studying medical draft examination records of 20,312 male subjects born in Jerusalem between January 1967 and December 1971. Additional information on birth weight and other demographic factors was abstracted from the Jerusalem Perinatal Study computerised database. A stepwise multiple logistic regression was used to estimate the odds ratios for developing asthma by 17 years of age in 500 g birthweight categories from less than 2000 g to 4500 g. The odds ratios were adjusted for the confounding effects of ethnic origin, social class (determined by area of residence), paternal education, maternal age, and birth order. The group with low birth weights (less than 2500 g, n = 1004) had a significantly increased risk of developing asthma by 17 years of age, with an adjusted odds ratio of 1.44 (95% confidence interval (CI) 0.79 to 2.66) for birthweight group less than 2000 g and 1.49 (95% CI 1.05 to 2.12) ...
The influence of birth weight and body mass in early adulthood on early coronary heart disease risk among Danish men born in...
This study examines the joint and separate influence of birth weight and body mass in young adulthood on subsequent coronary heart disease (CHD) risk. A cohort of 9,143 men born in Copenhagen, Denmark, in 1953, for whom information on birth weight and body weight and height around age 19 years were retrieved from birth certificates and conscript records, respectively, were followed from 1978 until 2005 (between age 25 and 52 years) for incident fatal and non-fatal CHD. Data on CHD were obtained through record linkage to the Cause of Death Registry and the National Patient Registry. During follow-up, a total of 475 men had a CHD diagnosis. Men with low birth weight, high body mass index (BMI) at age 19, a father from the working class, and low educational level at age 19 had an increased risk for CHD.

Gestational exposure to endocrine disrupting chemicals in relation to infant birth weight: a Bayesian analysis of the HOME...
In this study we examined the relationship between gestational exposure to 53 different EDCs and birth weight in a prospective birth cohort of mother-infant pairs. We found that exposure to phthalates and BPA, PFAS, PCBs, PBDEs or OCPs had null or small associations with birth weight. Other investigators have reported similar small or statistically non-significant associations between birth weight and phthalates , PCBs , PBDEs , and OCPs . Several other studies, however, have found associations between increased exposure to phthalates, PCBs, PBDEs or OCPs whereas we did not. A case-control study by Zhang et al.  revealed that low birth weight infants in China tended to have much higher meconium phthalate levels than infants who were normal weight. Additionally, a meta-analysis by Govarts et al.  reported that increased exposure to PCBs was associated with decreased birth weight. Lignell et al.  found a statistically significant inverse association between PBDE ...
Birth Weight and the Dynamics of Early Cognitive and Behavioural Development
Downloadable! In this paper we explore the impact of birth weight on childrens cognitive and behavioural outcomes using data from the UK Millennium Cohort Study. In order to deal with the endogeneity of birth weight we use an estimator based on the eliminant method. When coupled with ordinary least squares, this estimator allows us to bound the effects of birth weight. The results show that birth weight has significant but very small effects on male cognitive development at age 3 and on female cognitive and behavioural outcomes at age 3. We also find that birth weight affects age 5 outcomes only through previous achievements, and that the overall impact fades out over time. These findings call into question the effectiveness of birth weight as a policy target.
Association of maternal omega-6 fatty acid intake with infant birth outcomes: Korean Mothers and Childrens Environmental...
Maternal fatty acids (FAs) intake has an effect on birth weight, birth length, and gestational age, as fetal development is entirely dependent on the maternal essential FA supply. This study aimed to identify the association between the maternal intake of FAs and birth outcomes among pregnant women who participated in the Mothers and Childrens Environmental Health (MOCEH) prospective cohort study in South Korea. A total of 1407 pregnant women, aged 30.2 ± 3.7 years, at 12 to 28 weeks gestation were recruited between August 2006 and December 2010. Their dietary intake during pregnancy was investigated by the 1-day 24-h dietary recall method. The pregnancy outcome data-namely infants gestational age, birth weight, and birth length-were analyzed for their associations with their mothers intake of FAs. When adjusted for confounding factors, multiple regression analysis revealed adverse effects on birth weight (P = 0.031) and birth length (P = 0.025) with high maternal intake of omega-6 FAs. In the
Birth weight, childhood socioeconomic environment, and cognitive development in the 1958 British birth cohort study | The BMJ
Our study adds to the growing literature showing an association between birth weight and cognition across the normal range of birth weight,1-3 but only one such study has shown that the association persists with age beyond childhood.2 Few studies compare the association for birth weight and social background. The stronger influence of social background shown here is consistent with findings from two Scottish studies and with a Swedish study of intrauterine growth retardation in term infants followed to age 5. 1 9 21. Our study extends two strands of work from the late 1970s on developmental trajectories in the 1958 birth cohort. 20 22 23 A previous report estimated that a 1 kg increase in birth weight was associated with a 4 month increase in reading scores at 7 years; this estimate was little changed by adjustment for possible confounding factors.22 Those weighing less than 2 kg at birth had a 1.2 year lower reading age (0.4 SD) than those over 4 kg.22 The difference in maths z scores across ...
EDITOR-Williams and Poulton report that their 22 adolescent twins had lower blood pressure than singletons.1 They interpret their data as being contrary to the fetal origins hypothesis because they presume that twins, being small at birth, would tend to have higher rather than lower blood pressure in later life. As twins have different patterns of fetal growth from singletons, however, they were specifically excluded from the fetal origins hypothesis.2. There are several reasons why the low birth weight of twins may not have the same significance as intrauterine growth retardation in singleton births. Ultrasound evidence suggests that twins down regulate their growth rate early in gestation, possibly during the first trimester.3 Studies in fetal lambs suggest that early down regulation of fetal growth protects against growth retardation induced by undernutrition in later gestation.4 Finally, the metabolic and endocrine changes associated with growth retardation in singleton infants, including ...
Regression Analysis of Maternal Smoking Effect on Birth Weight - 佐藤 健一 - 広島大学著者一覧 - 広島大学 学術情報リポジトリ
Risk factors for low birth weight (LBW) have been indicated in many studies, but in Ja pan few studies have examined the amount of reduction in birth weight (BW). The goal of this study was to examine the association between maternal smoking among pregnant women and subsequent reduction in BW, corrected by the effect of potential confounders. To assess the effect of background factors other than maternal smoking, we established a model to estimate the contribution of each explanatory variable using logarithmic multiple regression. We then used the adjusted BW model to evaluate the direct effect of maternal smoking. To obtain information on maternal characteristics, including smoking status and characteristics of their infants, including BW, we conducted a questionnaire survey. After statistical adjustment for background factors, the mean of BW among infants of participants who smoked during pregnancy was roundtable significantly lower than that of non-smoking participants, but there was no ...

TY - JOUR. T1 - Size at birth and height in early adolescence. T2 - A prospective birth cohort study. AU - Araújo, Cora L P. AU - Hallal, Pedro C.. AU - Nader, Gisele A.. AU - Menezes, Ana Maria B. AU - Victora, Cesar G.. PY - 2008/4. Y1 - 2008/4. N2 - The aim of this study was to evaluate the association between size at birth (birthweight and birth length) and height in early adolescence in a prospective birth cohort study in Pelotas, Rio Grande do Sul, Brazil. Interviews were carried out in 1993, including measurements of birthweight and length, and in 2004-2005, including measurements of weight and height. This analysis includes 4,452 individuals, with a mean age of 11.3 years (standard deviation - SD = 0.3), representing a follow-up rate of 87.5%. Mean height at 11 years was 145.8 cm (SD = 7.9), or 144.9 cm (SD = 7.7) in boys and 146.8 cm (SD = 7.9) in girls. Birthweight and birth length were positively associated with height in early adolescence in the crude analysis, but after adjustment ...
Metabolic Effects of Birth Weight on Overweight and Obese Chinese Adults and Their Responses to Weight Loss - Full Text View -...
There is an exponential rise in the prevalence of type 2 diabetes and obesity in Singapore coincident with rapid nutritional and socioeconomic transition. Differing birth weights, even in the normal ranges, predisposes individuals to the risk of type 2 diabetes and obesity. We aim to examine the causal pathways, developmental contribution and effects of a weight loss intervention to this differential by evaluating the hypothesis that genomic, birth weight, developmental, lifestyle and environmental factors contribute to the variation in phenotype observed in adults with obesity and metabolic syndrome.. Although there are many large studies that examined the effect of birth weight on the expression of obesity and the metabolic syndrome phenotype, most of these studies usually lack in-depth physiological and epigenetic/genomic studies due to their large sample sizes. We therefore aim to explore such detailed aspects of physiological and epigenetic/genomic profiles on smaller but statistically ...
Seasonality, Malaria, and Impact of Prophylaxis in a West African Village II. Effect on Birthweight | The American Journal of...
Abstract The impact of malaria on low birthweight was investigated in Bougoula village (Sikasso region, Mali). In two successive years, pregnant women were followed until delivery. Phase I (1992) was observational, with 135 complete observations. Phase II (1993) included 126 participants, who were offered malaria prophylaxis with proguanil (200 mg/day) and chloroquine (300 mg/week). The results show that 1) infants of first and second pregnancies had lower birth weights (-382.7 ± 62.6 g; P < 0.0001) compared with higher rank pregnancies; 2) strong seasonal variation in birthweight was observed in Phase I, with an annual cycle, a nadir in January, and an amplitude of 372.4 g (P = 0.0002); 3) parasitemia measured during pregnancy was associated with lower birthweight in infants from first and second pregnancies, but not from higher parity mothers; and 4) malaria prophylaxis taken for 20 weeks or more in Phase II suppressed the seasonal variation of birthweight and the effect of low parity (+423.4 ±

THE EFFECTS OF EXERCISE ON BIRTH WEIGHT: A META-ANALYSIS
Previous research regarding the effects of exercise on pregnancy outcomes has been inconsistent. The purpose of this study was to adopt an objective research technique, meta-analysis, to summarize and analyze different studies with controversial results. Three coding variables (i.e., exercise duration, pre-pregnancy weight, and age) were selected in this study for comparisons. Though the effect size (ES) of the pregnant mothers who exercised under 30 minutes was greater than that of those who exercised between 30 and 60 minutes, the overall ES (-107.838, 95% CI = -482.93 to 267.26) indicated no significant birth weight differences between the two groups. On the whole, the results of this study support the notion that a significant positive relationship exists between birth weight and the prepregnancy weight. However, regression analysis indicated that a significant (p < .05) positive relationship existed between birth weight and the pre-pregnancy weight of the pregnant mothers (R =.75, p=.04). ...
THE MILLION WOMEN STUDY: Birth weight and adult cancer incidence: large prospective study and meta-analysis.
Yang TO, Reeves GK, Green J, Beral V, Cairns BJ; Million Women Study Collaborators.. Ann Oncol 2014;25:1836-43. BACKGROUND:. Most evidence about associations between birth weight and adult cancer risk comes from studies linking birth records to cancer registration data, where information on known risk factors for cancer is generally lacking. Here, we report on associations between birth weight and cause-specific cancer risk in a large cohort of UK women, and investigate how observed associations are affected by other factors.. METHODS:. A total of 453 023 women, born in the 1930s and 1940s, reported their birth weight, maternal smoking, parental heights, age at menarche, adult height, adult smoking, and many other personal characteristics. They were followed for incident cancer. Using Cox regression, relative risks by birth weight were estimated for cancers with more than 1500 incident cases, adjusting for 17 potential confounding factors, individually and simultaneously.. RESULTS:. Birth weight ...
Maternal KIR in Combination with Paternal HLA-C2 Regulate Human Birth Weight | The Journal of Immunology
Maternal inhibitory KIR2DL1 associates with pregnancy disorders linked to inadequate placentation, whereas maternal-activating KIR2DS1 associates with increased birth weight. These results suggest that variations in immune system genes, KIR and HLA-C, are under selection as a result of the necessity to keep human birth weight within the limits defined by the harmful consequences of low and high birth weight. A territorial demarcation between the mother and her fetus resulting from the interaction of maternal KIR on uNK and fetal HLA-C expressed by invading trophoblast could be the basis for achieving such a compromise. Both the KIR2DL1 and KIR2DS1 associations, at opposite ends of the birth weight spectrum, occur particularly in pregnancies where the fetus carries an additional HLA-C group 2 allele compared with the mother or the fetus has a single C2 allele that is of paternal but not maternal origin. Because C2 is the ligand for KIR2DL1/S1, this argues strongly for a role of the maternal KIR. ...

Low birth weight was associated with non-fatal coronary artery disease and stroke in nurses | Evidence-Based Nursing
Limited research on cardiovascular disease in women has been done despite the fact that cardiovascular disease is the main cause of mortality for women in industrial nations. The study by Rich-Edwards et al gives attention to birth weight as a marker of non-fatal cardiovascular disease including myocardial infarction, coronary revascularisation, and stroke.. In this substudy of the Nurses Health Study, the authors are thorough in their description of the purpose, design, data collection, data analysis, and limitations, which helps to establish credibility and context for the findings. They caution the reader in the interpretation of the data, noting that information was missing on several factors that affect birth weight; some misclassification of self reported birth weight existed; no data existed for 723 deaths caused by cardiovascular disease between 1976 and 1992; and several environmental and genetic factors that determine birth weight may have influenced cardiovascular risk. They noted ...
Q. Please help. I am trying to find information on the causes of my grandchilds low birth weight. She was full term and weighed 4 pounds 7 ounces. I am concerned about the consequences for her growth and development.. Should my daughter be concerned about the outcome of future pregnancies?. A. There are many causes for low birth weight. Some may predict future pregnancies resulting in low birth weight babies, or at least suggest some increased risk for more small babies, while others may be more likely to be once-only occurrences.. Among the possible causes: cigarette smoking during pregnancy, elevated blood pressure, problems with the placenta (which brings nutrition to the fetus blood stream from the mothers), and inadequate maternal weight gain during pregnancy.. The impact of a mothers health on her pregnancy and her babys future is one reason why prenatal care is so important. High blood pressure can develop for the first time during pregnancy in women with no prior history of it, and ...
Search Results | National Longitudinal Surveys
This paper tests whether parents reinforce or compensate for child endowments. We employ birth weight as a proxy for endowments and estimate how the difference in birth weight across siblings impacts specific parental investments, including breastfeeding initiation and duration, well-baby visits, immunizations, preschool attendance, and kindergarten entry age. We also examine whether parental investment in a child is impacted by her siblings endowments. Our results indicate that heavier birth weight children receive higher levels of most parental investment than their lower birth weight siblings suggesting that parental investments in infancy and early childhood reinforce differences in endowments. In one exception, we find weak evidence that lower birth weight children enter kindergarten slightly later than their normal birth weight siblings, which could be interpreted as a compensating parental investment. Presence of a low birth weight sibling in the household increases the likelihood of ...
BGDA Practical 12 - Third Trimester - Embryology
Environmental derived abnormalities relate to maternal lifestyle, environment and nutrition and while some of these directly effect embryonic development, there is also growing evidence that some effects are more subtle and relate to later life health events. This theory, now called developmental origins of health and disease (DOHAD or DOHaD) and also previously Fetal Origins Hypothesis, is based on the early statistical analysis carried out by David Barker (1938 - 2013) of low birth weight data collected in the early 1900s in the south east of England which he then compared with these same babies later health outcomes. The theory was therefore originally called the Barker Hypothesis and has recently been renamed as fetal origins or programming. Several origins have been suggested including: fetal undernutrition, endocrine (increased cortisol exposure), genetic susceptibility and accelerated postnatal growth. ...
It has been reported that reduced birth weight is associated with an increased risk of type 2 diabetes later in life (1-3). The largest such study was a meta-analysis of 14 studies involving a total of 132,180 individuals that demonstrated an association between lower birth weight and type 2 diabetes risk with an odds ratio of 1.32 (2). On a global level, reduced birth weight has been shown to be correlated with increased type 2 diabetes risk in 28 of 31 populations studied (3). Furthermore, low birth weight has been associated with both type 2 diabetes (P = 0.008) and impaired insulin secretion (P = 0.04) in 2,003 participants from the Helsinki Birth Cohort Study (HBCS) (4).. It has been proposed that the relationship between low birth weight and type 2 diabetes is genetically mediated, namely, the fetal insulin hypothesis (5,6). Because insulin is a key fetal growth factor, the genetic variants that reduce insulin secretion or insulin sensitivity might also reduce birth weight as well as ...

Abnormal retinal vascular… - University of Gothenburg, Sweden
OBJECTIVE: Intrauterine growth restriction (IUGR) resulting in low birth weight for gestational age may predispose one to development of cardiovascular disease later in life. Abnormal fetal blood flow in the presence of fetal growth restriction helps to distinguish infants with true fetal growth impairment from small but normal infants. Our goal was to investigate associations between IUGR with abnormal fetal blood flow and abnormal retinal vascular morphology at 18 years of age. METHODS: A prospective study was performed with 21 subjects with IUGR (abnormal fetal aortic blood flow velocity; birth weight small for gestational age; median birth weight deviation from the population mean of -31% [range: -22% to -42%] and in 23 subjects with birth weight appropriate for gestational age [normal fetal aortic blood flow velocity; median birth weight deviation of -2% (range: -10% to 22%)]). The retinal vessel morphology was evaluated by digital image analysis. RESULT: Subjects with IUGR (n = 21) had ...

Updated birth weight centiles for England and Wales | ADC Fetal & Neonatal Edition
We have used a large routinely available data set of all births in England and Wales to produce new up-to-date birth weight-for-gestational age centile charts. These updated centiles from births occurring in 2013 and 2014 provide a more valid tool with which to assess fetal growth. In particular, they provide a contemporary and nationally representative tool with which to more appropriately identify the proportion of stillbirths and neonatal deaths affected by IUGR for the analysis of the national perinatal mortality surveillance data. There are also potential implications for use in clinical practice, as the implementation of these new charts offers more accurate identification of the cohort of babies who require increased monitoring in the period immediately following birth for conditions such as hypoglycaemia. This is especially the case in those born at the earliest gestational ages and those born at the lower end of the birth weight distribution, where notable differences were observed ...

Clinical Outcomes of Submicroscopic Infections and Correlates of Protection of VAR2CSA Antibodies in a Longitudinal Study of...
We present the results of a prospective longitudinal study of MiP in Latin America to assess the impact of SMIs in pregnancy on delivery outcomes. We observed a high frequency of submicroscopic MiP (25%, 45/180). We did not detect a statistically significant difference in birth weights between infants born of pregnancies complicated by submicroscopic MiP. Of note, our study had adequate statistical power (80%) to detect a clinically meaningful difference in birth weights (250 g), and the mean difference observed in our cohort was 38 g, based on the 95% CI. We can therefore exclude an effect of SMI on infant birth weight in this Colombian cohort. However, in a secondary analysis looking at other delivery outcomes, women with mixed P. falciparum and P. vivax SMIs were at increased risk of PTB. According to the WHO Global Survey on maternal and perinatal health (32), patent malaria infection in pregnancy is not a risk factor for PTB in Latin America. However, the number of malaria cases in Latin ...
Fetal and infant markers of adult heart diseases | Heart
In Europe there are more than 20 large longitudinal studies in which the main focus has been or is to study prenatal or early life factors in relation to adult disease risk. Many of them are historical cohort studies, or data collection has started after birth retrospectively at various points of life. The most important historical cohort studies, from the point of view of the fetal origin hypothesis, are the Hertfordshire,4 14Preston,12 21 and Sheffield8 studies, as well as the Helsinki27 and Uppsala28 cohort studies.. The studies to date have had a number of important limitations that complicate interpretation. They have not been able to address the complexities of interactions between environmental and genetic factors in explaining the associations between maternal, fetal, and later life factors in the evolution of adult CVD risk. This is because they have been variously too small; retrospective and therefore subject to survival and selection biases; or prospective, but in children and ...

Children who were exposed to antenatal corticosteroids and had birth weights ⩽1500 g did not have adverse growth, cognitive, or...
There are few reports of long term follow up of neonatal survivors of corticosteroid treatment. The study by Doyle et al adds to our understanding of the effects of antenatal corticosteroids on key outcomes of growth and intellectual function that are of concern to parents and care providers. Additionally, Doyle et al examine these outcomes in infants who were less mature and had lower birth weights than those in previous studies.. The study sample was from Australia. The decision to provide antenatal steroids to the mothers was based on a clinicians decision and was not random. Thus, initial differences might have existed between the 2 groups of infants. The authors attempted to account for potential differences by adjusting for such confounding variables as birth weight, maternal education, and parental height. The potential confounding variables did not affect any of the statistically significant differences between the groups. The authors further reduced bias by ensuring that the outcome ...
Clinical profile of newborns undergoing physical therapy in a neonatal intensive care unit
Discussion. In the sample stratified by birth weight, it was observed that the death percentage was inversely proportional to gestational age (GA). The group with birth weight ≤ 1000g had a higher incidence of death, 11 (30.5%), compared to the other groups. The Apgar score less than 7 at 1 and 5 minutes is considered a risk factor for mortality 10. The study by Piccoli et al. 11 also showed a high incidence of prematurity and low birth weight with consequent morbidity and mortality.. Silva et al. 12 found that variables associated with death until the 27th day of life were type of delivery, notusing antenatal corticosteroids, preeclampsia, birth weight , 2500g, Apgar score , 7 at 5 minutes, endotracheal intubation, and notusing exogenous surfactant. For these authors, death was determined by the conditions of the pregnancy, delivery and the newborn.. The group considered extremely low birth weight, or birth weight ≤ 1000g presented a mean gestational age of 26.9 weeks and the group with ...
The Lifeways study is novel in having information on three generations of the same families. It is well established that infant birth weight (IBW) predicts individuals risk of adult chronic disease and more recently studies report cross-generation transmission of risk patterns. The aims of this analysis were to examine whether adults birth weights were associated with measures of own health status or social position and to relate adults birth weights to that of the index childs IBW. Finally, we assessed whether birth weight of either adults or children was associated with adult body mass index (BMI) of parents and grandparents. We included 1075 children whose IBW was recorded at recruitment from hospital records and 2546 adult cohort members followed from 2001 until 2014. At baseline, a sub-group of 920 adults had reported own birth weight (RBW). Results showed male adults RBW were significantly higher than females (P=0.001). Mothers RBW was significantly correlated with IBW (r=0.178, ...

Does birth weight predict childhood diet in the Avon longitudinal study of parents and children? | Journal of Epidemiology &...
The possibility that our findings were chance, bias, or residual confounding cannot be discounted. The effect sizes we found were small and the confidence intervals were large. Residual confounding by gestational age, social position, mid-parental height, birth order, or current weight and other factors could partly explain results. Adjustment for these factors greatly attenuated effect sizes, and despite the fact that attention was paid to the quality of measurement, these may have been made with error. The number of children with complete data to age 7 years was modest in comparison with the total number of children in our study, and our analysis restricted to these children assumed their data to be missing completely at random, which we know not to be the case. Hence bias attributable to selective loss to follow up could have weakened our results. However, the measurement of diet carries with it a degree of imprecision, and the true effect size of birth weight on macronutrient intakes could ...

Records of 606 animals from a crossbreeding experiment between Charlolais (Ch) and Caracu (Ca), carried out at Estacao Experimental Fazenda Modelo, in ponta Grossa-PR, Brazil, from 1981 to 1992, were analyzed to estimate additive and heterozygotic effects on birth weight (BW), weaning weight (WW), daily gain from birtht to weaning (DBGW), yearling weight (YW) and daily gain from weaning to yearling (DGWY).. ...
There is lack of evidence on the differential impact of maternal macronutrient consumption: carbohydrates (CHO), fats and protein on birth weight. We investigated the association between maternal dietary macronutrient intakes and their sub-components such as saccharides and fatty acids and birth weight. This analyses included 1,196 women with singleton pregnancies who were part of the CAffeine and REproductive health study in Leeds, UK between 2003 and 2006. Women were interviewed in each trimester. Dietary information was collected twice using a 24-h dietary recall about 8-12 weeks and 13-27 weeks of gestation. Multiple linear regression models adjusted for alcohol and smoking in trimester 1, showed that each additional 10 g/d CHO consumption was associated with an increase of 4 g (95 % CI 1, 7; P=0·003) in birth weight. Conversely, an additional 10 g/d fat intake was associated with a lower birth weight of 8 g (95 % CI 0, 16; P=0·04) when we accounted for energy contributing macronutrients ...
Transcriptome profiling of liver of non-genetic low birth weight and long term health consequences | BMC Genomics | Full Text
To examine the phenotypic response to a high-fat diet (hfd), mice were fed a normal diet (C) or a diet rich in lipids from weeks 6 to 24 of age (C + hfd). At the end of this period, significant weight and size differences were observed between the M and the control normal birth weight animals, regardless of sex and diet (p , 0.05) (Figure 2). However, these differences were significantly more pronounced throughout the entire life span of the mice in animals receiving the high-fat diet (p , 0.01). In order to assess anatomical variations derived from both diet and corporal condition (M or C), weight of 90 weeks old mice as well as their organs were recorded (Additional file 1: Table S1). Interestingly, liver, which plays an important role in metabolism and thus in the potential hfd outcome, didnt show any significant variation between M and C mice for both diets, regardless of sex. Several differences were found in other organs, however they lacked apparent correlation with the considered ...

Early Life Factors and Blood Pressure at Age 31 Years in the 1966 Northern Finland Birth Cohort | Hypertension
This study is the first to analyze a comprehensive range of maternal, birth, and childhood measures in relation to adult BP from a large well-characterized general population-based cohort studied since early pregnancy. Our main findings were that (1) the association between birth weight and SBP was inverse-linear, particularly for males, with or without adjustment for current BMI; (2) the association for DBP was inverse but weaker than for SBP; (3) other birth variables (gestational age, birth length, ponderal index, BW-GA) showed a similar pattern with BP, although less consistent than birth weight; (4) among females, the inverse association between gestational age and BP was stronger than that for birth weight; (5) infant change-up growth associated positively with BP; and (6) association of some early life factors (gestational age, ponderal index) with BP seems to be stronger in leaner adults.. A meta-analysis by Huxley et al22 of 82 studies with data on birth weight and BP concluded that ...
Maternal Gestational Diabetes, Birth Weight, and Adolescent Obesity | ELECTRONIC ARTICLES | Pediatrics
Because maternal GDM is associated with birth weight and birth weight is directly associated with later BMI, it makes sense to investigate the role of maternal GDM in the genesis of obesity. In this study, we documented a robust direct relationship between birth weight and BMI measured 9 to 14 years later. Each 1-kg increment of birth weight was associated with approximately a 30% increase in the prevalence of overweight, even after adjusting for maternal BMI and other relevant covariates.. In addition, we found that maternal GDM was associated with an OR of 1.4 for adolescent overweight, before controlling for birth weight and maternal BMI. This estimate was slightly attenuated by addition of birth weight to the model, suggesting that the association of GDM with later obesity could partially be explained by its influence on birth weight.. Maternal BMI played a confounding role in these analyses; adding it to the multivariate models resulted in a blunted association of maternal GDM with ...
Birth weight differences between those offered financial voucher incentives for verified smoking cessation and control...
The estimated increase in birth weight caused by the offer of incentives in the CPIT trial was 21 g overall, but for the subgroup of women who quit as a result of the offer of incentives, and would not have been able to do so without the offer, it was 145 g. Throughout, we have viewed this as the causal effect of the intervention, within the subgroup who are susceptible to (comply with) it, but the value of 145 g can equally be seen as the causal effect of stopping smoking on birth weight, within this subgroup of women for whom the offer of incentives is sufficient to help them to quit. This is in line with birth weight differences associated with smoking cessation recorded by other researchers - 160 grams for light smoking (1-9 cigarettes per day) and 230 grams for heavy smoking (,9 cigarettes per day) .. To try to understand this analysis, Fig. 1 gives the raw data. Comparison of those who continued to smoke shows that those in the incentives group had babies with a slightly lower birth ...
Comparison of eleven commonly used formulae for sonographic estimation of fetal weight in prediction of actual birth weight |...
Objectives: The aim of the study is to compare the accuracy of 11 formulas in predicting fetal weight. Material and methods: The study includes 1072 pregnant women of gestational age from 28 to 42 weeks, who gave birth between January and June 2017. Pregnant women were divided into five groups; group 1, where actual birth weight (ABW) was less than 2500 g, group 2, where ABW was between 2500-4000 g, group 3, where ABW was above 4000 g. Group 4 - newborns with birth weight under 10 percentile and group 5 - newborns with birth weight above 90 percentile. The accuracy of the estimated fetal weight (EFW) was assessed by calculating absolute percentage error (APE) and limits-of-agreement. R Spearman correlation was utilized between EFW and ABW. Results: The most accurate formula for group 1 is Hadlock3 (MAPE = 7.04%), the narrowest limits of agreement has Combs - [mean (SD): 99.41 g (269.57 g)]. For group 2, the lowest MAPE (5.43%) has Ott, the narrowest limits of agreement belongs to Combs - [mean ...
Estimation of optimal birth weights and gestational ages for twin births in Japan | BMC Public Health | Full Text
As multiple pregnancies show a higher incidence of complications than singletons and carry a higher perinatal risk, the calculation of birth weight - and gestational age (GA)-specific perinatal mortality rates (PMR) for multiple births is necessary in order to estimate the lowest PMR for these groups. Details of all reported twins (192,987 live births, 5,539 stillbirths and 1,830 early neonatal deaths) in Japan between 1990 and 1999 were analyzed and compared with singletons (10,021,275 live births, 63,972 fetal deaths and 16,862 early neonatal deaths) in the annual report of vital statistics of Japan. The fetal death rate (FDR) and PMR were calculated for each category of birth weight at 500-gram intervals and GA at four-week intervals. The FDR according to birth weight and GA category was calculated as fetal deaths/(fetal deaths + live births) × 1000. The perinatal mortality rate (PMR) according to birth weight and GA category, was calculated as (fetal deaths + early neonatal deaths)/(fetal deaths +

Effects of psychosocial risk factors and prenatal interventions on birthweight: evidence from New Jerseys HealthStart Program ...
Reichman NE, et al. Effects of psychosocial risk factors and prenatal interventions on birthweight: evidence from New Jerseys HealthStart Program. Perspect Sex Reprod Health. May/Jun 2003;35(3):130-137.. This research was done to verify the linkages between the Medicaid prenatal care programs, in response to expansions of the Medicaid eligibility criteria. According to the fully adjusted model, the interventions designed to reduce behaviors like smoking, drinking, and using hard drugs (but not marijuana) during pregnancy had no favorable effects on birthweight. In contrast, participation in the WIC Program was associated with an increase in mean birthweight of 22 grams. The increase was 48 grams among inadequately nourished women only.. ...
Folic Acid Supports Healthy Birth Weight | Whole Foods Magazine
Researchers conducted a population-based study and a systematic review to see whether folic acid affects a babys size compared to others of the same gestational age. A small size at birth is associated with health issues later in life. The present study included data from 108,525 pregnancies; 84.9% of the mothers had taken folic acid during pregnancy. About 26% of these cases began supplementation before pregnancy. The highest rate of small size for gestational age was associated with mothers that didnt take folate, with 16.3% having newborns under the 10th percentile for birth weight and 8.9% having newborns under the fifth percentile for birth weight. Women taking folic acid before conception were less like to have a baby with a low birth weight for its gestational size.. Published in WholeFoods Magazine, January 2015 (online 12/11/14). ...
Both high and low birth weight linked to fatty liver disease - The Statesman
Children born with lower or higher weight than normal may be at increased risk for developing non-alcoholic fatty liver disease (NAFLD) by the time they become teenagers, says a study.. Advanced scarring of the liver was associated with low birth weight, while more inflammation was linked to high birth weight, according to the study published in the Journal of Pediatrics.. With the obesity epidemic, we are seeing more babies with high birth weight than ever before, said study co-author Mark Fishbein from Stanley Manne Childrens Research Institute at Ann & Robert H. Lurie Childrens Hospital of Chicago in the US. Our study shows that these kids are more likely to have serious liver damage by the time they are teenagers, Fishbein said.. Nonalcoholic fatty liver disease is the most common cause of chronic liver disease in children and typically is diagnosed in early adolescence. In its most severe form it can lead to liver failure and the need for liver transplantation.. Being able to ...
The prevalence and related factors of low birth weight
Background and aims:The most common reason in neonatal mortality rate in the world is low birth weight (LBW). The objective of our study was to determine the prevalence and related factors associated in birth weight in Garmsar, Iran in 2013. Methods: This cross sectional study was carried out on 683 live births which delivered in Garmsar in 2013. The required information was collected by examining the health records of pregnant women and completion of the data registration forms. Data collection was controlled by using SPSSand analyzed by using an Independent T-test, Chi-square test and logistic regression. Results: According to the results, 32 infants out of 683 infants born in 2013 had low birth weight, i.e. the weight less than 2500g. LBW prevalence estimated in this study was 4.7%. There were significant statistical relations between low birth weight and the variables including number of births, mothers occupation and interval of less than 3 years between pregnancies and systolic and diastolic

Methods Data from the Medical Birth Registry of Norway (MBRN) were linked with data from RevNatus, a nationwide observational register recruiting women with inflammatory rheumatic diseases. Singleton births in women with SLE included in RevNatus 2006-2015 were cases (n=180). All other singleton births registered in MBRN during this time (n=498 849) served as population controls. Z-score for birth weight adjusted for gestational age and gender was calculated. Disease activity was assessed using Lupus Activity Index in Pregnancy. We compared z-scores for birth weight, pre-eclampsia and preterm birth in cases with inactive disease, cases with active disease and population controls. ...
US Birth Weight/Gestational Age-Specific Neonatal Mortality: 1995-1997 Rates for Whites, Hispanics, and Blacks | ELECTRONIC...
Objective. In recent years, gains in neonatal survival have been most evident among very low birth weight, preterm, and low birth weight (LBW) infants. Most of the improvement in neonatal survival since the early 1980s seems to be the consequence of decreasing birth weight-specific mortality rates, which occurred during a period of increasing preterm and LBW rates. Although the decline in neonatal mortality has been widely publicized in the United States, research suggests that clinicians may still underestimate the chances of survival of an infant who is born too early or too small and may overestimate the eventuality of serious disability. So that clinicians may have current and needed ethnic- and race-specific estimates of the chances of early survival for newborn infants, we examined birth weight/gestational age-specific neonatal mortality rates for the 3 largest ethnic/racial groups in the United States: non-Hispanic whites, Hispanics, and non-Hispanic blacks. Marked racial variation in ...
Maternal hemoglobin and birth weight: systematic review and meta-analysis - - ScopeMed.org - Deposit for Medical Articles
A systematic review published in 2000 studied the association between maternal anemia and birth weight; however, some results were inconclusive. A review of randomized control trials and cohort studies published in 2013 concluded that daily prenatal iron use substantially improves birth weight in a linear dose response manner. Thus, a systematic review and meta-analysis of observational epidemiological studies was conducted to contemporarily estimate the relationship between prenatal maternal hemoglobin and birth weight. We searched four electronic databases for observational epidemiological studies, which reported birth weight as an outcome measure and ascertained prenatal maternal anemia by hemoglobin measurement. Thirty-three studies met inclusion criteria. Meta-analysis of five studies showed that neonates born to women with anemia were, on average, 303 g lighter in birth weight than those born to women without anemia (95% CI: 19.20 588.26; I = 91%; five studies; p = 0.04). On the basis of ...
Early Pregnancy Weight Gain - The Obesity Society
16,000 participants showed early weight gain had the largest effect on infants birth weight FOR RELEASE:. August 28, 2017. CONTACT:. Robyn Gordon, The Obesity Society: [email protected] SILVER SPRING, MD: Weight gain in early pregnancy has the greatest impact on infant size at birth, according to a new study published today in Obesity. The study is the largest ever analysis of the effect that weight gain in early pregnancy has on infant size.. The study examined 16,218 pregnant mothers throughout the first, second and third trimesters in Tianjin, China to determine the risk of infants size at birth. Results found weight gain early in pregnancy, before 24 weeks-regardless of the weight gain later-had the greatest impact on infant size. Infants born to women with weight gain that exceeds the 2009 Institute of Medicine guidelines for weight gain during pregnancy, prior to 24 weeks, were 2.5 times more likely to be born large.. Maternal obesity and weight gain in pregnancy have been ...
Retinopathy of prematurity in infants of birth weight | 2000 g after haemorrhagic shock at birth. | British Journal of...
BACKGROUND: The risk of retinopathy of prematurity (ROP) is associated with low birth weight and low gestational age. For ROP screening examination is recommended in infants weighing , or = 1500 g or of less than 32 weeks gestational age. METHODS: From 1991 ROP screening was performed in 452 premature infants with either a birth weight , or = 1500 g (n = 303) or a birth weight , 1500 g (n = 149) and who required additional oxygen supplementation or underwent surgery with general anaesthesia before estimated term. RESULTS: Unexpectedly, three infants with birth weights between 2080 and 2325 g and a gestational age of 32 or 33 weeks developed stage 2 or 3 ROP. One of these underwent cryocoagulation. In three infants, preterm birth was induced by sudden placental abruption with severe prenatal blood loss followed by haemorrhagic shock. The umbilical cord packed cell volume was reduced to 0.14-0.19 (normal 0.43-0.63). All three infants underwent surgery with general anaesthesia within the first ...

Caffeine is linked to low birth weight - Healthcanal.com : Healthcanal.com
Caffeine intake from different sources was linked to lower birth weight and a higher number of babies who were small for gestational age. For a child with an expected average birth weight (3.6kg) this is equivalent to 21-28 g lost per 100 mg caffeine per day. An intake of 200-300 mg caffeine per day is associated with an increase in the risk of giving birth to a small for gestational age baby by almost a third. Babies who are small for gestational age are at higher risk of both short-term and lifelong health problems. Caffeine consumption is strongly correlated with smoking which is known to increase the risk for both preterm delivery and the baby being small for gestational age. In this study we found no association between caffeine intake and preterm delivery but we did find an association between caffeine and babies who were small for gestational age. This association remained even when we corrected for maternal smoking habits and when we only looked at non-smoking mothers, which implies ...
IJERPH | Free Full-Text | Combined Effects of Prenatal Exposures to Environmental Chemicals on Birth Weight
Prenatal chemical exposure has been frequently associated with reduced fetal growth by single pollutant regression models although inconsistent results have been obtained. Our study estimated the effects of exposure to single pollutants and mixtures on birth weight in 248 mother-child pairs. Arsenic, copper, lead, manganese and thallium were measured in cord blood, cadmium in maternal blood, methylmercury in maternal hair, and five organochlorines, two perfluorinated compounds and diethylhexyl phthalate metabolites in cord plasma. Daily exposure to particulate matter was modeled and averaged over the duration of gestation. In single pollutant models, arsenic was significantly associated with reduced birth weight. The effect estimate increased when including cadmium, and mono-(2-ethyl-5-carboxypentyl) phthalate (MECPP) co-exposure. Combining exposures by principal component analysis generated an exposure factor loaded by cadmium and arsenic that was associated with reduced birth weight. MECPP induced

Impact of low birth weight and cardiovascular risk factors on endothelial function in early adult life. - Radcliffe Department...
BACKGROUND: Low birth weight is related to increased risk of coronary heart disease in adults and recently has been associated with vascular endothelial dysfunction in children. We investigated whether the relation between birth weight and endothelial function was still present in early adult life and whether there was an interaction with emerging risk factors. METHODS AND RESULTS: In 315 adults (165 women, 150 men, aged 20 to 28 years), high-resolution ultrasound was used to determine endothelium-dependent and -independent vascular responses of the brachial artery. Vascular measures were related to classic risk factors (smoking history, lipid profile, blood pressure, fasting insulin, exercise capacity, body mass index, and combined risk score) and birth weight. Low birth weight was associated with reduced flow-mediated dilation (coefficient=0.18 kg(-1), 95% CI 0.004 to 0.35, P:=0.04) but not with endothelium-independent dilation. The difference in flow-mediated dilation between the top and bottom

Birth Weight and Blood Pressure in Young Adults | Circulation
An innovative feature of the current study is the use of twins to test the prenatal programming hypothesis. Twins share the same maternal environment, and monozygotic twins are genetically identical. Nevertheless, each fetus has its own fetoplacental environment, as reflected by its birth weight, that may differ substantially between twin members. By comparing the BP of the heaviest twin at birth with that of the lighter sibling, potential confounding maternal and genetic characteristics can be controlled. So far, only 4 studies have applied this twin approach for BP,4-7 but their results have not been consistent. Dwyer et al4 and Poulter et al5 found a tendency for the monozygotic twin who was lightest at birth to have the highest BP later in life, suggesting that the association between birth weight and adult BP is at least partly independent from maternal and genetic influences. Ijzerman et al6 observed an inverse relationship between intrapair birth weight difference and intrapair difference ...
Evaluating the Role of Birth Weight and Gestational Age on Acute Lymphoblastic Leukemia Risk Among Those of Hispanic Ethnicity....
High birth weight is an established risk factor for childhood acute lymphoblastic leukemia (ALL), especially in children younger than 5 years of age at diagnosis. The goal of this study was to explore the association between being born large for gestational age and the risk for ALL by race/ethnicity to determine if the role of this risk factor differed by these characteristics. The authors compared birth certificate data of 575 children diagnosed with ALL who were younger than 5 years and included in the Texas Cancer Registry, Texas Department of Health, between the years 1995 and 2003 with 11,379 controls matched by birth year. Stratified odds ratios were calculated for risk of ALL by birth weight for gestational age, categorized in 3 groups, small, appropriate, and large for gestational age (SGA, AGA, and LGA, respectively), for each race/ethnicity group. The risk of developing ALL was higher among Hispanics who were LGA (odds ratio [OR] = 1.90, 95% confidence interval [CI]: 1.34-2.68) ...
Severity of winter and impact on calf birth weights | Lautner Farms
Ranchers have asked that question during many springs and veterinarians have speculated for years. The debate rages on. This is obviously a difficult subject to research because you cannot have a control group of cows to compare to a treatment group that is exposed to a cold winter while still running on the same pasture. Therefore research data on this subject is limited.. University of Nebraska researchers (Colburn and co-workers) have done the next best thing. They have monitored the birth weights of genetically similar calves across three different winters and have related average winter temperatures to birth weights. A 3-year study was conducted to evaluate effects of high and low air temperatures and wind chills during winter months on subsequent calf birth weights and calving difficulty of spring-born calves. Records on approximately 400 2-year-old heifers and their calves were used. Heifer and calf genetics were the same each year. Heifers were fed similar quality hay free-choice ...

Association between umbilical cord glucocorticoids and blood pressure at age 3 years | BMC Medicine | Full Text
Animal data show that decreased activity of placental 11-beta-hydroxysteroid dehydrogenase type 2 (11β-HSD2), which potently inactivates glucocorticoids (e.g. cortisol) to inert forms (cortisone), allows increased access of maternal glucocorticoids to the fetus and programs hypertension. Data in humans are limited. We examined in humans the association between venous umbilical cord blood glucocorticoids, a potential marker for placental 11β-HSD2 enzyme activity, and blood pressure at age 3 years. Among 286 newborns in Project Viva, a prospective pre-birth cohort study based in eastern Massachusetts, we measured cortisol (F) and cortisone (E) in venous cord blood and used the ratio of F/E as a marker for placental 11β-HSD2 activity. We measured blood pressure (BP) when the offspring reached age 3 years. Using mixed effects regression models to control for BP measurement conditions, maternal and child characteristics, we examined the association between the F/E ratio and child BP. At age 3 years,

Higher Weight and Weight Gain after 4 Years of Age Rather than Weight at Birth Are Associated with Adiposity, Markers of...
Background: Fetal and early life growth is associated with adult risk of obesity and cardiometabolic disease. However, little is known about the relative importance of birth weight and successive periods of weight gain on markers of cardiometabolic risk in childhood in low-income populations. Objectives: The objective was to study associations of birth weight and weight gain velocities in selected age intervals from birth to 60 mo with height, fat-free mass (FFM), and markers of adiposity and cardiometabolic risk at 60 mo. Methods: In a prospective cohort study of 375 Ethiopian children aged 60 mo, we estimated individual weight gain velocities in the periods between birth and 3, 6, 24, 48, and 60 mo using linear-spline mixed-effects modeling. Subsequently, we analyzed associations of birth weight, weight gain velocities, and current weight with height, FFM, and markers of adiposity and cardiometabolic risk. Results: Weight gain from 48 to 60 mo and weight at 60 mo rather than birth weight were ...
Low Birth Weight May Signal Heart Disease
According to researchers from Johns Hopkins Childrens Center, an infant with low birth weight carries particles in the blood that can lower the amount of high-density lipoprotein (HDL) cholesterol that it produces. These particles in the blood contain apolipoprotein C-1, known for lowering HDL, or good cholesterol. Blood from the umbilical cords of 163 infants born at 28 or more gestational weeks and at approximately 1.3 lb less than normal weight were analyzed. Researchers found higher levels of apolipoprotein C-1 in 19% of these infants. Low birth weight and higher-than-normal levels of this substance have been associated with the death of the hearts smooth-muscle cells. These cells are important to protecting the circulatory system from artery-clogging plaque, which can lead to a heart attack. Researchers concluded that it is important to check C-1 levels in low-birth-weight infants, and that these children should eat low-fat diets to reduce their risk of heart disease. ...
Birth weight <i>versus</i> gestational age as a predictor of viability of extremely low birth weight babies :Mostafa Abolfotouh...
Although neurodevelopmental outcome of very preterm neonates has also significantly improved over this period, the pace of improvement in central nervous system morbidity appears to have lagged behind that of survival. In addition, neurodevelopmental impairment in infants born extremely immature persists into school age, and the level of impairment is often underestimated when standardized tests are being used for the assessment of these patients cognitive and neurological status. Among extremely preterm children, cognitive and neurologic impairment is common at school age. A comparison with their classroom peers indicates a level of impairment that is greater than is recognized with the use of standardized norms. The extremely low birth weight (ELBW) survivors in school at age 8 years who were born in the 1990s have considerable long-term health and educational needs. A meta-analysis of case-control studies reported from 1980 to November 2001 that examined cognitive and behavioral outcomes ...

Silveira and Laurette Dubé Publication: British Journal of Nutrition, Vol. 119, No. 11, June 2018 Abstract: Evidence suggests that both high and low birth weight children have increased the risk for obesity and the metabolic syndrome in adulthood. Previously we have found altered feeding behaviour and food preferences in pre-school children and adults born with low birth weight. In this study, we investigated if birth weight was associated with different intake of fat, carbohydrate and/or protein at 6-12 years of age. This is a cross-sectional study where 255 guardians answered online and telephone questions including anthropometrics and demographic data, parental family food rules (food control, encouragement and restriction) and a complete web-based FFQ for their children (130 boys and 125 girls). Baseline demographic and parental food rules

Psychosocial predictors of labor/ delivery complications and infant birth weight: a prospective multivariate study. Journal of Psychosomatic Obstetrics and Gynecology 2001;21(3).
OBJECTIVE: Low birth weight has been associated with hyperlipidemia, hypertension, diabetes, and coronary heart disease in adult life, but the precise mechanism is debated. The endothelium is thought to play a pivotal role in each of the above conditions with abnormalities being detectable before the development of overt disease. To investigate the possibility that endothelium has a role in mediating the excessive risk of adult vascular disease associated with low birth weight, endothelial function was assessed in young healthy adults who were either of low or normal birth weight at term. RESEARCH DESIGN AND METHODS: Twelve low birth weight (2.2 +/- 0.05 kg, mean +/- SEM) subjects (six men/six women; age 28 +/- 0.2 years) and twelve age- and sex-matched normal birth weight (3.3 +/- 0.07 kg) control subjects were studied. The L-arginine-nitric oxide pathway was assessed in the forearm vascular bed by using venous occlusion plethysmography during intra-arterial brachial infusion of acetylcholine, ...

Modern sow lines have been genetically selected for increased litter size. This increase in litter size, however, is also associated with higher piglet mortality. This piglet mortality can be partly explained by lower piglet birth weights and higher within-litter variation in birth weight. The main hypothesis of this thesis is that these factors, the lower piglet birth weights and the higher within-litter variation, are (at least partly) explained by impaired follicular development of sows during and after lactation, as this is the period in which antral follicles develop that contain the oocytes that will give rise to the next litter. Increased litter size also results in increased metabolic demands of modern sows during lactation, due to the necessary higher milk production. As the metabolic state highly influences follicular development, the increased metabolic demands may therefore impair follicular development and contribute to lower piglet birth weights and higher within-litter variation ...
Low birth weight
A baby is considered as having a low birth weight if he or she weighs less than 2,500g (2.5kg) when born. Learn about the causes and risk factors for having a low birth weight baby.
In the U.S. teen mothers are more likely to give birth to low birth weight babies than non-teen mothers. There is also substantial evidence that smoking is a risk factor correlated with low birth weight. Low birth weight is a costly outcome in both the short and long term for parents, children, and society at large. This paper examines the causal link between teen age smoking behavior and low birth weight. We use a variety of empirical techniques including fixed effects and a matching estimator to identify the impact of smoking on babies of teen and non-teen mothers. We find that both OLS and matching estimator results yield large impacts of smoking on birth weight for teens and adults. However, when we control for unobservables through a fixed effects model, the impact of smoking on birth ...

Objectives We assessed whether maternal employment during pregnancy - overall and in selected occupational sectors - is associated with birth weight, small for gestational age (SGA), term low birth weight (LBW), length of gestation, and preterm delivery in a population-based birth cohort design. Methods We used data from ,200 000 mother-child pairs enrolled in 13 European birth cohorts and compared employed versus non-employed women. Among employees, we defined groups of occupations representing the main sectors of employment for women where potential reproductive hazards are considered to be present. The comparison group comprised all other employed women not included in the occupational sector being assessed. We performed meta-analyses of cohort-specific estimates and explored heterogeneity. Results Employees had a lower risk of preterm delivery than non-employees [adjusted odds ratio (ORadj) 0.86, 95% confidence interval (95% CI) 0.81-0.91]. Working in most of the occupational sectors studied ...
Low Birth Weight | Greater Portland Pulse
Babies with low birth weights face increased risks of infection, impaired development, developmental delays, and higher rates of infant death.[i] They are more likely to suffer from long-term disabilities, including cerebral palsy and blindness. Low birth weight can be influenced by a number of factors, including maternal and fetal health. For example, women who use tobacco, have poor nutrition, consume alcohol, or use illegal or some prescription drugs while pregnant are at increased risk of giving birth to low-weight babies.[ii] Chronic conditions including diabetes, heart defects, and kidney disease can also increase a womans risk of giving birth to a low-weight baby..

The Broken Sow: Fix Your Sow and You Fix the Piglets | The Pig Site
Sow Nutrition. What are the piglet birth weights?. Birth weights are a direct reflection of how the sow is fed during the last 15 to 20 days of gestation. What are the days return to first estrus?. Long days to estrus is a result of expended energy during lactation. Generally as a function of low energy intake to meet these needs.. What are the weaning weights?. Weaning weights are a reflection of sow milk production and piglet health. Generally the sow should be able to milk 11 to 12 liters of milk per day.. Lactation feed intake and proper lactation feed density (nutrients) is needed to get the required milk production.. What is the milk production of your sow during lactation?. To determine what your sows are milking take the 21 day liter weight subtract the litter birth weight, divide by 21 days and multiply by 4. (It takes 4 grams of milk to make one gram of gain). 82 Kgs (wean weight) - 21.5 Kgs birth weight is 60.5 Kgs of growth, divide by 21 days is 2.87 grams per day times 4 is 11.5 ...
We have studied 477 8-year-old Indian children to define the relationship between birth weight and cardiovascular risk factors, including insulin resistance syndrome (IRS) variables and plasma total and LDL cholesterol concentrations. All risk factors were strongly related to current weight. After adjustment for current weight, age, and sex, lower birth weight was associated with higher systolic blood pressure (P = 0.008), fasting plasma insulin and 32-33 split proinsulin concentrations (P = 0.08 and 0.02), glucose and insulin concentrations 30 min postglucose (P = 0.06 and 0.04), subscapular/triceps skinfold ratio (P = 0.003), and plasma total and LDL cholesterol concentrations (P = 0.002 and 0.001).
