Effect of breastfeeding education on the feeding pattern and health of infants in their first 4 months in the Islamic Republic of Iran.
(25/2970)
This quasi-experimental study was conducted in Shiraz, the Islamic Republic of Iran, on 120 pairs of mothers and infants in a maternity hospital that had a rooming-in programme. All 59 mothers in the study group received breastfeeding education, face-to-face, after delivery and during follow-up for 4 months in the mother and child health (MCH) centre or in their homes; the remaining 61 mothers comprised the control group. Exclusive breastfeeding rates were significantly higher in the study group (54%) than in the control group (6.5%), but 5% and 18% of infants, respectively, in the study and control groups had stopped breastfeeding by the age of 4 months. The mean number of days of diarrhoea experienced by infants in the study group were significantly lower (P < or = 0.004) than in the control group. At the end of 4 months, the mean weight and length of the infants were significantly higher (both P < 0.05) in the study group than in the control group. The findings indicate that rooming-in is very important for promoting exclusive breastfeeding and that there is a need for continuous breastfeeding education of mothers. (+info)
Perinatal and neonatal determinants of childhood type 1 diabetes. A case-control study in Yorkshire, U.K.
(26/2970)
OBJECTIVE: To identify environmental factors that exert their effect in the perinatal and neonatal period and influence the subsequent onset of insulin dependent (type 1) diabetes during childhood. RESEARCH DESIGN AND METHODS: A population-based case-control study of data abstracted from the hospital obstetric and neonatal records of 196 children with type 1 diabetes and 325 age- and sex-matched control subjects. Analysis of matched sets by conditional logistic regression was conducted for a range of perinatal and neonatal factors. RESULTS: A significantly raised risk was observed for illnesses in the neonatal period (OR 1.61, 95% CI 1.06-2.44), the majority of which were infections and respiratory difficulties. Exclusive breast feeding as the initial feeding method was significantly protective (OR 0.65, 95% CI 0.45-0.94). There were no significant associations with high- or low-birth weight, being firstborn or small-for-dates. All factors significant (5% level) for the entire dataset, that is, maternal age, type 1 diabetes in mothers, preeclampsia, delivery by cesarean section, neonatal illnesses, and initial breast feeding were modeled and the OR remained significant for all variables other than cesarean section. CONCLUSIONS: The findings are based on medical record data that cannot be subject to biased recall of mothers. Neonatal illnesses increased and initial breast feeding decreased the risk of childhood type 1 diabetes. Further determinants of risk are mothers with type 1 diabetes, older mothers, and preeclampsia during pregnancy. (+info)
Influence of socioeconomic conditions on growth in infancy: the 1921 Aberdeen birth cohort.
(27/2970)
OBJECTIVES: To identify environmental influences on infant growth using data from a birth cohort established in 1921. DESIGN: A longitudinal cohort study. SETTING: Aberdeen 1921-22. SUBJECTS: Five hundred and sixteen individuals (263 boys and 253 girls) born in Aberdeen during 1921. Health visitor assessments ranged from two to 40 (47% received at least 10 visits). No records were available for infants who died. Individuals were grouped as those who did not breast feed, those who breast fed initially but not at 6 months, and those who were continuing to breast feed at 6 months. MAIN OUTCOME MEASURE: Rate of weight gain over the 1st year of life. A random effects model was used to identify environmental factors and conditions contributing to rate of weight gain in the 1st year of life. RESULTS: Breast feeding rates were about 80% and 50% at 10 days and 6 months, respectively. Breast fed infants were significantly heavier than bottle fed infants at 28 days but this difference disappeared by 12 months. Significant negative effects on rate of weight gain, independent of initial body weight, were found for overcrowding in family homes and maternal parity, whereas social class had no effect. CONCLUSION: Studies based on historical cohorts that have controlled socioeconomic variables only in terms of social class (derived from parental occupation) may have been subject to residual confounding. Growth in the 1st year of life is likely to reflect a number of environmental influences, some of which may continue to have effects throughout early life and beyond. (+info)
Prevention of vertical transmission of HIV: analysis of cost effectiveness of options available in South Africa.
(28/2970)
OBJECTIVE: To assess the cost effectiveness of vertical transmission prevention strategies by using a mathematical simulation model. DESIGN: A Markov chain model was used to simulate the cost effectiveness of four formula feeding strategies, three antiretroviral interventions, and combined formula feeding and antiretroviral interventions on a cohort of 20 000 pregnancies. All children born to HIV positive mothers were followed up until age of likely death given current life expectancy and a cost per life year gained calculated for each strategy. SETTING: Model of working class, urban South African population. RESULTS: Low cost antiretroviral regimens were almost as effective as high cost ones and more cost effective when formula feeding interventions were added. With or without formula feeding, low cost antiretroviral interventions were likely to save lives and money. Interventions that allowed breast feeding early on, to be replaced by formula feeding at 4 or 7 months, seemed likely to save fewer lives and offered poorer value for money. CONCLUSIONS: Antiretroviral interventions are probably cost effective across a wide range of settings, with or without formula feeding interventions. The appropriateness of formula feeding was highly cost effective only in settings with high seroprevalence and reasonable levels of child survival and dangerous where infant mortality was high or the protective effect of breast feeding substantial. Pilot projects are now needed to ensure the feasibility of implementation. (+info)
Breast feeding and obesity: cross sectional study.
(29/2970)
OBJECTIVE: To assess the impact of breast feeding on the risk of obesity and risk of being overweight in children at the time of entry to school. DESIGN: Cross sectional survey SETTING: Bavaria, southern Germany. METHODS: Routine data were collected on the height and weight of 134 577 children participating in the obligatory health examination at the time of school entry in Bavaria. In a subsample of 13 345 children, early feeding, diet, and lifestyle factors were assessed using responses to a questionnaire completed by parents. SUBJECTS: 9357 children aged 5 and 6 who had German nationality. MAIN OUTCOME MEASURES: Being overweight was defined as having a body mass index above the 90th centile and obesity was defined as body mass index above the 97th centile of all enrolled German children. Exclusive breast feeding was defined as the child being fed no food other than breast milk. RESULTS: The prevalence of obesity in children who had never been breast fed was 4.5% as compared with 2.8% in breastfed children. A clear dose-response effect was identified for the duration of breast feeding on the prevalence of obesity: the prevalence was 3.8% for 2 months of exclusive breast feeding, 2.3% for 3-5 months, 1.7% for 6-12 months, and 0.8% for more than 12 months. Similar relations were found with the prevalence of being overweight. The protective effect of breast feeding was not attributable to differences in social class or lifestyle. After adjusting for potential confounding factors, breast feeding remained a significant protective factor against the development of obesity (odds ratio 0.75, 95% CI 0.57 to 0.98) and being overweight (0.79, 0.68 to 0.93). CONCLUSIONS: In industrialised countries promoting prolonged breast feeding may help decrease the prevalence of obesity in childhood. Since obese children have a high risk of becoming obese adults, such preventive measures may eventually result in a reduction in the prevalence of cardiovascular diseases and other diseases related to obesity.

Pregnancy and early onset pauciarticular juvenile chronic arthritis.
(30/2970)
OBJECTIVES: To study interaction of early onset pauciarticular juvenile chronic arthritis (EOP-JCA) and pregnancy in the Polish population, in particular to confirm the ameliorating effect of pregnancy on disease activity reported by others and to analyse the factors that govern the occurrence of postpartum flare, with emphasis on the potential role of breast feeding. METHODS: The reproductive outcome and disease status in 39 adult women with history of EOP- JCA was examined by means of a questionnaire and an interview. In all patients the disease onset occurred before the 6th birthday, 19 had persistent pauciarticular JCA (PeEOP-JCA) and 20 had extended pauciarticular JCA (ExEOP-JCA). RESULTS: 23 women had at least one successful pregnancy, seven had unsuccessful pregnancies but all of them had also one or more successful pregnancies. Among those who have never been pregnant (n=16) there was a higher frequency of eye disease and ExEOP-JCA compared with the rest of the group. In almost all cases pregnancy was associated with remission of disease activity, however a postpartum flare appeared after 22 pregnancies (52%). The flares were more frequent in women who had an active disease before pregnancy, had a flare after a previous pregnancy and/or were breast feeding. CONCLUSIONS: In EOP-JCA patients pregnancy generally has a good outcome and induces amelioration of disease activity. After delivery, however, a flare of disease often appears, especially in women who were breast feeding, had a postparum flare previously or had an active disease before pregnancy. The pattern of interaction between disease and pregnancy found in EOP-JCA makes EOP-JCA similar in this respect to RA, but different from systemic lupus erythematosus and ankylosing spondylitis.

Counselling on breastfeeding: assessing knowledge and skills.
(31/2970)
Reported are the results of a randomized controlled trial to assess the effectiveness of the WHO/UNICEF 40-hour course "Breastfeeding counselling: a training course". The course was conducted in a maternity hospital which provides care to a low-income population in a metropolitan area in Sao Paulo, Brazil. Health workers from 60 health units were randomly assigned to be either participants (20) or controls (40), and their breastfeeding knowledge and skills were assessed before and immediately after the course, as well as 3 months later. Immediately after the course the participants' knowledge of breastfeeding had increased significantly compared to controls. Both their clinical and counselling skills also improved significantly. When assessed 3 months later, the scores remained high with only a small decrease. The implementation of the course was also evaluated. The methods used were participatory observation, key interviews and focus group discussion. In the 33 sessions of the course, the average score was 8.43 out of 10. Scores were highest for content and methodology of the theory sessions, and lowest for "use of time", "clinical management of lactation", and "discussion of clinical practice". "Breastfeeding counselling: a training course" therefore effectively increases health workers' knowledge and their clinical and counselling skills for the support of breastfeeding. The course can be conducted adequately using the material and methodology proposed, but could be more satisfactory if the time allocated to exercises and clinical practice sessions were increased.

Maternal factors, obstetric history and smoking stage of change.
(32/2970)
BACKGROUND: Maternal smoking is known to be associated with low educational status, low social class and younger age groups. The aim of this study was to determine if maternal smoking and stage of change relating to smoking is associated with other maternal variables such as intention to breastfeed and attend antenatal classes, having a planned pregnancy, previous obstetric history and child health problems. METHOD: A cross-sectional survey was carried out of all women who attended antenatal clinics at the Leicester Royal Infirmary NHS Trust over a two-week period. The data comprised 254 completed questionnaires. Results Intention to breastfeed was more common among non-smokers as shown by smoking status (p < 0.001) and smoking stage of change (p < 0.05). Having a planned pregnancy was more common among non-smokers as determined by smoking status (p < 0.001) and stage of change (p < 0.05). Intention to attend antenatal classes showed no significant relationship with smoking status but the majority of those planning to attend antenatal classes were in the action-maintenance stage (p< 0.05). Previous obstetric complications were not associated with either smoking status or stage of change. Smokers were more likely to have at least one child with asthma (p < 0.05) or respiratory infections (p < 0.001). Having at least one child with asthma or respiratory infections was more common among precontemplators (p < 0.05). CONCLUSION: Smoking stage of change should be assessed in antenatal care so that appropriate information can be offered to pregnant smokers. The development and evaluation of stage-specific smoking cessation materials should offer considerable benefits to maternal and infant health. (+info)
