Body composition in infancy may be of importance for later health. In particular, infant body composition may be relevant regarding obesity risk in childhood. Recent advances in body composition methodology using air displacement plethysmography (ADP) have provided possibilities to accurately measure body composition of infants in a quick and non-invasive manner. The aims of this thesis were to study associations of parental body composition using ADP, glucose homeostasis during pregnancy and infant genetics with infant body composition also using ADP. When using ADP in adults, a correction for the thoracic gas volume (TGV) is needed and TGV can be predicted using equations developed in nonpregnant adults. Thus another aim was to study the validity of using such equations during pregnancy.. Parent couples were invited to this study at a routine visit to a maternity clinic in Linköping between September 2008 and October 2010. When the mother was in gestational week 32, parental body composition ...
Pork is the most widely eaten meat in the world and recent evidence shows that diets high in pork protein, with and without energy restriction, may have favourable effects on body composition. However, it is unclear whether these effects on body composition are specific to pork or whether consumption of other high protein meat diets may have the same benefit. Therefore we aimed to compare regular consumption of pork, beef and chicken on indices of adiposity. In a nine month randomised open-labelled cross-over intervention trial, 49 overweight or obese adults were randomly assigned to consume up to 1 kg/week of pork, chicken or beef, in an otherwise unrestricted diet for three months, followed by two further three month periods consuming each of the alternative meat options. BMI and waist/hip circumference were measured and body composition was determined using dual energy x-ray absorptiometry. Dietary intake was assessed using three day weighed food diaries. Energy expenditure was estimated from
For a long time it was generally accepted that Underwater-weighing was considered the gold-standard when it came to the most reliable and accurate way to assess body composition. Later, DEXA was developed and also offered the advantage of being able to measure not only Body Fat % but also bone mineral density. It is also a very reliable and accurate tool for measuring body composition. Within the last twenty years, several other techniques have become available, with air-displacement plethysmography (using the BODPOD) offering a cheaper (I use this term loosely) way to assess body composition (only $50,000 compared to $120,000). The Bod Pod has been shown to be a valid and reliable tool for measuring body composition, particularly when compared to other field-based measures such as skin-fold testing or BIA. Again, its important to select an assessment technique that gives you the most accurate reading when it comes to measuring your body composition, particularly if you are using to detect ...
The objective of this study was to examine the association of self-reported physical activity (PA) with body composition in 290 college students (49% male, 60% White) 18-25 years of age. Outcome measures included: self-reported PA levels calculated in MET-hrs·wk-1 from the International Physical Activity Questionnaire (IPAQ); body mass index (BMI; in kg·m-2); and body composition variables estimated by dual-energy X-ray absorptiometry (DXA). Mean activity levels of the sample were 39.8 ± 23.8 MET-hrs·wk-1. Participants were divided into quartiles of PA levels: ≥0 to |24.0, ≥24.0 to |34.0, ≥34.0 to |51.25, and ≥51.25 MET-hrs·wk-1 and body composition variables were compared by group. Chi-square analyses revealed a significant difference for gender by PA quartile [χ2 (3, N=290) = 32.42, p | 0.0001], and for gender by race by PA quartile [χ2 (9, N=290) = 37.82, p | 0.0001]. MET-hrs·wk-1 was inversely correlated with %BF (r = -0.40, p | 0.0001) but not BMI (r = 0.05, p = 0.43). When
Body composition measurement by dual energy absorptiometry was carried out in 160 men (age 45-87 years) and 407 women (age 20-88 years) consisting of volunteers and 25 men and 14 women with chronic obstructive airways disease (COAD) not receiving steroids from a hospital respiratory clinic. The objectives of this study were to provide normal reference values for adult Chinese including the elderly; to examine the effect of age and COAD on body composition; and to compare the use of body mass index (BMI) as a measure of obesity or malnutrition compared with body composition measurements. Values for body composition were different when compared with studies in the Caucasian population. In both sexes, height and lean mass decreased in a linear fashion with aging. In men, total body water increased till the 55-65 age group and then decreased. In women, total body water and bone mineral content also decreased with aging in a linear fashion. Changes in weight, BMI, fat mass and percentage fat with aging were
Researchers have found that fat-free mass index, but not body mass index, was a significant predictor of survival in patients with idiopathic pulmonary fibrosis (IPF), a debilitating form of pneumonia. Unlike body mass index, fat-free mass index takes into account the amount of muscle mass a person is carrying.

Excessive BF is associated with morbidity and mortality in severe obesity. After surgical treatment, effectiveness of weight loss has strong correlation with changes in body composition (fat and lean mass), emphasizing the importance of its evaluation by a simple, accurate, reproducible and inexpensive method [9-32]. There are three different models of body compartments used for body composition assessment: two compartment (2C) model (Fat Mass and Fat Free Mass), three compartment (3C) model (Fat Mass, Total Body Water and Dry Fat Free Mass) and four compartment (4C) model (Fat Mass, Total Body Water, minerals and residual)[6,7]. The traditional 2C model divides the body into fat and Fat Free Mass (FFM). The assumption that FFM has a constant density in health and disease subjects is an important limitation of the model. The FFM includes protein, TBW, mineral tissue (soft tissue and bone) and glycogen. Then, any difference in the proportions of these components will lead to FM or FFM estimation ...

Previous studies (Munsters & Saris, 2012; Smeets & Westerterp-Plantenga, 2008; Stote et al., 2007) on the relationship between meal frequency, body composition, and appetite have targeted sedentary or obese individuals. These studies were conducted using energy-balanced conditions for maintaining BW. Almost all these studies were short in duration, ranging from one to several days. Long-term dietary intervention studies have not been conducted, even on the general population. A very limited intervention study by Iwao et al. (1996) used a hypocaloric diet for weight loss in boxers. However, Schoenfeld et al. (2015) meta-analysis found a lack of significant impact of higher versus lower meal frequencies after sensitivity analysis on weight loss. Contrastingly, this study focused on the influence of meal frequency in athletes during weight gain. The diets were carefully monitored to maintain a positive EB, and the intervention period was much longer than in previous studies. Moreover, despite the ...

BackgroundWe aimed to describe newborn body composition and identify which anthropometric ratio (weight/length; BMI; or ponderal index, PI) best predicts fat mass (FM) and fat-free mass (FFM).MethodsAir-displacement plethysmography (PEA POD) was used to estimate FM, FFM, and body fat percentage (BF%). Associations between FFM, FM, and BF% and weight/length, BMI, and PI were evaluated in 1,019 newborns using multivariate regression analysis. Charts for FM, FFM, and BF% were generated using a prescriptive subsample (n=247). Standards for the best-predicting anthropometric ratio were calculated utilizing the same population used for the INTERGROWTH-21st Newborn Size Standards (n=20,479).ResultsFFM and FM increased consistently during late pregnancy. Differential FM, BF%, and FFM patterns were observed for those born preterm (34+0-36+6 weeks gestation) and with impaired intrauterine growth. Weight/length by gestational age (GA) was a better predictor of FFM and FM (adjusted R2=0.92 and 0.71, respectively)
BODY COMPOSITION BODY COMPOSITION. The term body composition describes the various components that make up a persons body. The absolute and relative amounts and distribution of these components are relevant to diverse body functions and, thus, influence the state of health and various disease risks. A commonly used body composition model organizes the body to five levels of increasing complexity: from atomic to molecular, cellular, tissue-system, and whole body.

AIM: To present a visual representation of changes in body composition, leptin, insulin, estradiol and follicular stimulating hormone (FSH) levels in relation to menarche in girls. METHODS: Participants were a subset of healthy girls (n = 108) enrolled in a longitudinal study of growth and development conducted at the General Clinical Research Center at the Massachusetts Institute of Technology (MIT). Participants were seen annually from before menarche until 4 years postmenarche for measures of body composition and serum levels of leptin, insulin, estradiol and FSH. Body composition was determined by bioelectrical impedance. Standardized body composition and hormone levels were smoothed and plotted relative to menarche to visualize patterns of change. RESULTS: At menarche, the mean percentage body fat (%BF) of girls was 24.6% (SD = 4.1%) after menarche %BF was approximately 27%. Leptin levels averaged 8.4 ng/mL (SD = 4.6) at menarche and were approximately 12 ng/mL after menarche. Changes in leptin

In physical fitness, body composition is used to describe the percentages of fat, bone, water and muscle in human bodies. Because muscular tissue takes up less space in our body than fat tissue, our body composition, as well as our weight, determines leanness. Two people of the same sex and body weight may look completely different because they have a different body composition. The most accurate estimation of body composition is derived from body density by means of the equation of fractional densities which states that the overall density of a mixture containing more than one substance (each with a different density) can be calculated if the proportion and density of each component substance is known. For determination of body composition the body is often assumed to be composed of four basic substances (four compartment model) with the general form of the equation as follows: 1 / D b = w / D w + f / D f + p / D p + m / D m {\displaystyle 1/Db=w/Dw+f/Df+p/Dp+m/Dm} Where: D b {\displaystyle ...

Therefore, studies suggest that the change of life is why many women notice their body composition changing - some women start to notice a different shape of their body (one the hips and thighs, and sometimes the waist and stomach). Some women experience what they think is bloating of the stomach and are unable to lose the tummy weight during the change. More studies are required to determine the exact role the change of life plays in a womans body composition. (NAMS.org. (2019 ...
The medical significance of body composition in general and the technology of bioelectrical impedance analysis specifically offer substantial added value to diagnostic support and treatment. Many different medical specialties such as oncology, nephrology, cardiology, nutrition and sports medicine profit from the precise measurement of body composition. Nevertheless, up until now the medical community has had no standard textbooks and no platform where researchers and clinicians could obtain and share information on these subjects. As an expert in medically validated body composition analysis, seca wanted to change the situation by helping to spread knowledge of this field and heighten awareness of this fascinating material, said Dr. Michael Johannes Maisch, Chief Medical Advisor at seca. We are pleased that we could engage the renowned experts Dr. Bosy-Westphal and Dr. Wootton, who will make the mBCA science center the number one address for everyone who wants to learn more about this subject ...
Despite well-known sex differences in body composition it is not known whether sex-specific genetic or environmental effects contribute to these differences.We assessed body composition in 2,506 individuals, from a young Dutch genetic isolate participating in the Erasmus Rucphen Family study, by dual-energy X-ray absorptiometry and anthropometry. We used variance decomposition procedures to partition variation of body composition into genetic and environmental components common to both sexes and to men and women separately and calculated the correlation between genetic components in men and women.After accounting for age, sex and inbreeding, heritability ranged from 0.39 for fat mass index to 0.84 for height. We found sex-specific genetic effects for fat percentage (fat%), lean mass, lean mass index (LMI) and fat distribution, but not for BMI and height. Genetic correlations between sexes were significantly different from 1 for fat%, lean mass, LMI, android fat, android:gynoid fat ratio and WHR,
OBJECTIVES: The aim of the present study was to test the association between muscular strength, functional limitations, body composition measurements and indexes of sarcopenia in a sample of community-dwelling, elderly women at the high end of the functional spectrum. DESIGN: Cross-sectional. SUBJECTS: In all, 167 women aged 67-78 y were selected from the general population in central Verona. A group of 120 premenopausal healthy women aged 20-50 y represented the young reference group. MEASUREMENTS: Body weight, height, body mass index (BMI) and the presence of acute and chronic conditions were evaluated in each subject. Body composition was measured by dual-energy X-ray absorptiometry (DXA). Physical functioning was assessed using a modified version of the Activities of Daily Living Scale. Dominant leg isometric strength was measured with a Spark Handheld Dynamometer.

The aim of the study was to examine the effect a five week pedometer intervention on anthropometric measurements such as skin calliper measurements, waist and hip measurements and aerobic fitness. Fifteen female students volunteered to participate in the study. Their mean (± s) age, body mass, height and body mass index were 20.8 ± 0.7 years, 70 ± 6 cm, 166 ± 4.3 cm and 25.4 ± 1.9 Kg.m2 respectively. Participants completed a three day baseline step log followed by a five week step log. Pre and post intervention measurements were completed. First a YMCA VO2 sub-maximal test and second skin calliper application on four points of the body, tricep, bicep, subscapual and suprailliac were taken to measure body fat percentage and sum of skinfold. The tests were repeated after the five week intervention. Over the five weeks there was a decrease in body mass, (-0.1kg) body fat percent (-0.9%), and waist circumference (-1.4 cm) albeit not significant. There was a statistical decrease in the sum of ...

Background Altered growth, body composition and abnormalities of skeletal mineralisation have been reported in offspring of mothers with type 1 and type 2 diabetes mellitus.. Aims The authors hypothesised that children born to mothers with type 1 diabetes mellitus (CDM) would be taller, have higher body mass index (BMI), greater fat mass, thicker diaphyseal bone cortices and reduced trabecular bone mineral density (BMD), as compared to those born to non-diabetic mothers.. Methods Anthropometric, body composition and bone parameters were assessed using dual-energy x-ray absorptiometry (DXA) and peripheral quantitative CT in 67 white Caucasian CDM (35 boys; age 5-18 years) and in 246 (121 boys) age-matched controls.. Results CDM were taller (p,0.0001), heavier (p,0.0001) and had higher BMI (p=0.02), and had 32% more total body fat mass and 7.5% more total body lean mass than controls. At the total body and lumbar spine (L1-L4) sites, CDM had significantly higher bone area and bone mineral content ...
T2D was diagnosed according to the criteria reported in the WHO/IDF 2006 consultation [WHO/IDF consultation. Geneva, Switzerland, 2006]. Hypertension was diagnosed by BP readings and from medical records. Abdominal obesity was assessed by WC using the standards for Asians developed by the International Diabetes Federation (2005). Physical activity of patients was assessed by the number of steps measured by pedometers (Hoffmann-La Roche Ltd, Basel, Switzerland).. Anthropometrical indicators included age (years), weight (kg), BMI (kg/m2), WC (cm). Body composition parameters including fat mass (in % of total body weight and total kg), visceral fat rating (units), fat free mass (kg), total body water (% and kg), muscle mass (% and kg), bone mass (% and kg), metabolic age (years), basal metabolic rate (kcal/day), and bioimpedance (Ohms) were measured using a Tanita-SC330S Body Composition Analyzer (Tanita Corp., Tokyo, Japan). On the same blood samples, complete blood cell count, erythrocyte ...
Knowledge and visible success are top motivatorStefanie Wirtz from the Selbsthilfeverband AdipositasHilfe Deutschland e.V. and Coordinator of the Adipositaszentrum Lüneburg emphasized how important body composition information is for obesity therapy and motivation. She says, When patients know how their bodies are composed of water, muscle and fat, they are more apt to understand how to succeed at weight loss. On top of that, success becomes visible in body composition measurements even before the patient can see the changes in the mirror or on the bathroom scale. That increases motivation and treatment compliance enormously! One affected person, Stefanie Bohn, confirms that: It was an incredible relief for me to know that I am not just made of fat as I often thought. That was good for my self-esteem and for my motivation too. Because now that I know about my body composition, I can take a more targeted approach to managing my weight ...
Body composition can be looked at as how much of your body is fat and lean muscle mass. It can tell us more about our training and nutrition.. Our body weight is basically just a product of gravity. It tells us very little except what our body weighs right now.. If we increase our lean muscle mass by 1 kilogram and reduce our body fat by 1 kilogram - expect our body weight to stay the same. If you didnt know this and saw your scales not budge after a month of killing it in the gym - youd be pretty pissed off right? Well now you know so now you can prepare.. Now to measure body composition there are various methods. Skin calipers are a manual tool for assessing body fat - tiny clamps that will grasp onto skin folds around the body and then using calculations can provide your body fat %. The accuracy of skin folds depends on the tester doing it so I suggest a coach or trainer do it. If you find a coach who is good, pay him/her. Its a skill less and less trainers have now a days.. The GOLD ...
We analyzed 197 patients with stage III esophageal cancer who were treated with pac and carboplatin in a prospective study between 2008 and 2013. CL of pac, which was estimated using nonlinear mixed effects modeling (NONMEM) was used as a measure of systemic pac exposure (de Graan et al, 2012). Skeletal muscle index (SMI, cm2/m2), muscle attenuation (MA) and visceral adipose tissue (VAT; cm2) were measured at the level of the 3rd lumbar vertebra on computed tomography (CT) scans performed before treatment. Gender-specific differences in pac CL, based on the 1st quartile and the 4th quartile of the SMI and VAT measurement were analyzed with a Mann-Whitney test. A Spearman rank correlation (r) was calculated to explore the relationship between pac CL and SMI, VAT and MA, respectively. ...
UNLABELLED The contributions of systemic versus local insulin-like growth factor-I (IGF-I) action for mediating fat-free mass (FFM) accretion have yet to be fully clarified, but circulating IGF-I is the preferred measure in clinical practice, and its merits as a biomarker have been demonstrated for a number of physiological outcomes. PURPOSE To test the hypothesis that bioavailable IGF-I would have a stronger association with physical activity-induced FFM accretion than total IGF-I and would serve as a prognostic indicator of FFM accretion. METHODS Seventy-seven young healthy women (21 ± 5 yr, 62.7 ± 8.5 kg, 27.0% ± 6.0% body fat) participated in 8 wk of Army basic training involving intense physical activity. Total and bioavailable IGF-I; IGF binding proteins (IGFBP) 1, 2, 3, 4, 5, and 6; and body composition parameters were measured before and after the training. RESULTS There were significant (P≤0.05) increases in FFM (6%) and decreases in fat mass (-13%). Total IGF-I and IGFBP-4 to -6
BACKGROUND & AIMS: Sarcopenic obesity may be defined by a high fat to fat-free mass (FM/FFM) ratio. Skeletal muscle may be negatively influenced by the pro-inflammatory milieu associated with visceral fat, while the loading effect induced by a heavier body mass index (BMI) may enhance muscle anabolism. Recently, a new anthropometric measure based on waist circumference (A Body Shape Index, ABSI) was developed. In this study we have assessed the predictive power of ABSI on the FFM index (FFMI), a surrogate marker of lean mass. METHODS: Standard anthropometric parameters and ABSI as well as body composition data (fat and fat-free mass determined by bioelectrical impedance analysis) were assessed in 111 female and 89 male overweight/obese subjects, with no clinically significant co-morbidities. Groups with higher- or lower-ABSI were identified according to median values of this index. RESULTS: In women and men, ABSI did not correlate with BMI, while multiple linear regression indicated that BMI ...

Purpose: The influence of female sex hormones on body fluid regulation and metabolism homeostasis has been widely studied. However, it remains unclear whether hormone fluctuations throughout the menstrual cycle (MC) and with oral contraceptive (OC) use affect body composition (BC). Thus, the aim of this study was to investigate BC over the MC and OC cycle in well-trained females. Methods: A total of 52 eumenorrheic and 33 monophasic OC-taking well-trained females participated in this study. Several BC variables were measured through bioelectrical impedance analysis 3 times in the eumenorrheic group (early follicular phase, late follicular phase, and midluteal phase) and on 2 occasions in the OC group (withdrawal phase and active pill phase). Results: Mixed linear model tests reported no significant differences in the BC variables (body weight, body mass index, basal metabolism, fat mass, fat-free mass, and total body water) between the MC phases or between the OC phases (P , .05 for all ...

Background: Although lipoatrophy is uncommon with current antiretroviral therapy (ART), fat accumulation continues to occur, and its association with protease inhibitors (PIs) has been questioned. The effect of integrase inhibitors vs. PIs on body composition has not been established.. Methods: We compared the percentage change in lean mass (by DXA), peripheral fat (limb fat by DXA and subcutaneous abdominal fat (SAT) by CT scan of abdomen), and central fat (trunk fat by DXA and visceral abdominal fat (VAT) by CT) over 96 weeks in HIV-infected treatment-naive participants randomized to open labeled tenofovir disoproxil fumarate-emtricitabine (TDF/FTC) plus atazanavir-ritonavir (ATV/r), darunavir-ritonavir (DRV/r), or raltegravir (RAL) in ACTG 5260s, a substudy of A5257. DXA and CT measurements were standardized and centrally read. Linear regression, adjusting for the stratification factors of baseline cardiometabolic risk and HIV-1 RNA, was used to compare the 96-week percentage change in fat ...

Although obesity is a risk factor for hip osteoarthritis (OA), the role of body composition, if any, is unclear. This study examines whether the body mass index (BMI) and body composition are associated with hip cartilage changes using magnetic resonance imaging (MRI) in community-based adults. 141 community-based participants with no clinical hip disease, including OA, had BMI and body composition (fat mass and fat free mass) measured at baseline (1990 to 1994), and BMI measured and 3.0 T MRI performed at follow-up (2009-2010). Femoral head cartilage volume was measured and femoral head cartilage defects were scored in the different hip regions. For females, baseline BMI (β = −26 mm3, 95% Confidence interval (CI) -47 to −6 mm3, p = 0.01) and fat mass (β = −11 mm3, 95% CI −21 to −1 mm3, p = 0.03) were negatively associated with femoral head cartilage volume. Also, while increased baseline fat mass was associated with an increased risk of cartilage defects in the central superolateral region

TY - JOUR. T1 - Effect of interaction of gender and energy intake on lean body mass and fat mass gain in infant baboons. AU - Lewis, D. S.. AU - Bertrand, H. E.. AU - Masoro, E. J.. AU - McGill, H. C.. AU - Carey, K. D.. AU - McMahan, C. A.. PY - 1984/1/1. Y1 - 1984/1/1. N2 - The hypothesis that energy intake influences differently the composition of mass gain during the preweaning period was tested in male and female baboons. Infant baboons were fed either a high (92 kcal/100 g formula) or a low (49 kcal/100 g formula) caloric formula from birth. Body mass, lean body mass and fat mass of each baboon were measured directly at weaning (18 weeks of age). Lean mass and fat mass gained from birth to 18 weeks was estimated by using body composition data from eight newborn baboons. Both energy intake and gender significantly influenced gain of total mass, lean mass and fat mass. There was a significant gender by diet interaction effect of the gain of fat mass. There was a significant gender by diet ...
In this study, the bioelectrical impedance analysis (BIA), skinfold thickness measurement (STM) and dual-energy X-ray absorptiometry (DXA), as a reference method, were compared with each other in the assessment of body composition in elderly (62-72-year-old) Finnish women (n=93). BIA had better agreement with DXA in the assessment of fat free mass (FFM, R2=0.70, Sres=2.1) and fat mass (FM, R2=0.93, Sres=2.3) than the STM (FFM, R2=0.62, Sres=2.4; FM, R2=0.89,Sres=2.8). There was quite a large variation in the estimates when different BIA prediction equations were used. The equation developed in this study, FFM (kg)=-128.06 + 1.85 x BMI-0.63 x weight + 1.07 x height - 0.03 x resistance +10.0 x waist-hip ratio, yielded a small and unbiased error (0.5 +/- 1.6 kg), with a small residual standard deviation (R2=0.83, Sres=1.6). However, error associated with the estimate of FM was positively related to the degree of FM. BIA(Heitmann) equation yielded unbiased estimates of both FFM and FM (FFM, R2=0.77, ...
Objective: This study aimed to compare the various anthropometric and body composition parameters based on the ethnicity and the absence or presence of menarche.Design: A cross-sectional study with incomplete sampling, using the subject as the evaluation unit.Subjects: the final sample of 550 subjects was composed of 122 Japanese and 179 Caucasian premenarcheal adolescents, and 72 Japanese and 177 Caucasian postmenarcheal adolescents.Methods: the variables of body composition were measured through the following methods: bioelectrical impedance analysis, near-infrared interactance (NIR), Slaughter cutaneous skinfold equations and body mass index. Weight, height and sitting height were also evaluated.Results: the Japanese pre- and postmenarcheal girls presented lower weight and height values when compared with the Caucasian girls. in general, the Japanese premenarcheal girls presented less fat and fat-free mass than the premenarcheal Caucasian girls. This fact was demonstrated through NIR results. ...
Bioelectrical impedance analysis (BIA) is a commonly used method for estimating body composition, and in particular body fat. Since the advent of the first commercially available devices in the mid-1980s the method has become popular owing to its ease of use, portability of the equipment. It is familiar in the consumer market as a simple instrument for estimating body fat. BIA actually determines the electrical impedance, or opposition to the flow of an electric current through body tissues which can then be used to estimate total body water (TBW), which can be used to estimate fat-free body mass and, by difference with body weight, body fat. Many of the early research studies showed that BIA was quite variable and it was not regarded by many as providing an accurate measure of body composition. In recent years technological improvements have made BIA a more reliable and therefore more acceptable way of measuring body composition. Nevertheless, it is not a gold standard or reference method. ...
The purpose of this study was to examine the influence of fat-free adipose tissue mass (FFAT) on association between dual-energy X-ray absorptiometry (DXA)-derived lean soft tissue mass and skeletal muscle mass (TMM). Forty-one middle-aged and older women were recruited for this study. Percent body fat, total and appendicular fat mass (tFM and aFM, respectively), and total and appendicular lean soft tissue mass (tLM and aLM, respectively) were measured using a DXA. FFAT was calculated based on the methods of a previous study. TMM was estimated from the ultrasound-derived prediction equation. The subjects were separated into three groups based on DXA-determined percent fat: low (n=12, ,25 %), middle (n=15, ,= 25 and ,35 %), and high (n=14, ,= 35 %). DXA-derived aLM was greater in high than in middle or low, although ultrasound-estimated TMM was similar among the three groups. There was a strong correlation between aLM and TMM (r=0.905, p,0.001). The difference between aLM and TMM was correlated ...

Obesity is a problem which is more and more common in Polish population. The reason for that is excessive energy delivery from food against the quantity used by organism, as well as too small physical activity. These factors lead to excessive increase of body fat quantity which has a detrimental impact on the health condition. The purpose of the study is a body composition assessment in women aged 50-80 living in Kujawsko-Pomorskie Voivodeship. 1902 female inhabitants of Kujawsko-Pomorskie Voivodeship participated in the study which was divided into six age groups. The fat mass level and the fat free mass level of the body was evaluated with the assistance of electrical bioimpedance method. The content of water in the organism and, indirectly, the basic metabolism level were also determined. With age women exhibit the decrease of fat free body mass and water level in the organism; whereas the body mass and, at the same time, the body fat content are observed to increase for women between 50 and ...

Physical fitness is a powerful marker of health in youth. Studies in adolescents and adults suggest that higher fat mass is related to worse physical fitness. However, there is limited knowledge whether fat mass and fat-free mass are associated with physical fitness already in preschoolers. Baseline data from the MINISTOP (Mobile-based INtervention Intended to STop Obesity in Preschoolers) trial was utilized for this cross-sectional analysis. Body composition was assessed using air-displacement plethysmography. Fat mass index [fat mass (kg)/height(2) (m)] and fat-free mass index [fat-free mass (kg)/height(2) (m)] were used to provide height-adjusted measures of body composition. Physical fitness was measured using the PREFIT (FITness testing in PREschool children) battery, which assesses cardiorespiratory fitness, upper-body and lower-body muscular strength as well as motor fitness. In total, this study included 303 children (168 boys and 135 girls), who were on average 4.48 +/- 0.15 years old. ...
BACKGROUND: Skeletal muscle wasting is related to muscle dysfunction, exercise intolerance, and increased mortality risk in patients with COPD. STUDY OBJECTIVES: The aims of this study were to investigate the effects of whole-body exercise training on body composition in normal-weight patients with COPD, and to study the relationship between changes in body composition and functional capacity. SETTING AND PARTICIPANTS: Fifty patients with COPD (FEV(1), 39% of predicted [SD, 16]) admitted to the pulmonary rehabilitation center at Hornerheide, and 36 healthy age-matched control subjects (for baseline comparison) were included. INTERVENTIONS: Patients participated in a standardized inpatient exercise training program consisting of daily submaximal cycle ergometry, treadmill walking, weight training, and gymnastics during 8 weeks. MEASUREMENTS: Fat-free mass (FFM) was measured by bioelectrical impedance analysis. None of the patients met the criteria for nutritional supplementation (body mass index ...
Accurate measurement of body fat mass (BFM) is critical in assessing overweight and obesity that pause health implications of other non-communicable diseases (NCDs). The traditional commonly used method, body mass index (BMI) is not adequate to measure BFM because it does not account for body composition. Hence the study measured BFM and free fat mass (FFM) using bioelectrical impedance analysis (BIA) in relation to BMI. This allowed for better estimation of human nutritional status and determination of misclassification when BMI method is used alone. A total of 247 participants, comprising 54% females and 46%males aged 18-55 years were selected from University of Zambia (UNZA), Chalimbana University (CHAU), Natural Resources Development College (NRDC) and Chongwe College of Education (CCE). Participants were further categorized into young adults aged 18-39 years (77%) and old adults aged 40-55 years (23%). Both measurements of BMI and BIA were taken in the morning following overnight fasting ...
BACKGROUND: Prader-Willi syndrome (PWS) children have impaired growth, and abnormal body composition. Previous 1-year controlled studies showed improvement of height and body composition during GH-treatment.. OBJECTIVE: To evaluate growth, body composition and body proportions during GH-treatment in a large group of PWS children.. DESIGN/PATIENTS: We performed a randomized controlled GH trial in 91 prepubertal PWS children (42 infants, 49 children, aged 3-14 years). After stratification for age, infants were randomized to GH-treatment (GH-group; 1 mg/m(2)/day; n = 20), or no treatment (control group; n = 22) for 1 year. In the second year all infants were treated with GH. After stratification for BMI, children , 3 years of age were randomized to GH-treatment (GH-group; 1 mg/m(2)/day; n = 27) or no treatment (control group; n = 22) for 2 years. Anthropometric parameters were assessed once in every 3 months. Body composition was measured by Dual Energy X-ray Absorptiometry.. RESULTS: Median ...
The enrichment of diet with nutrients with potential benefits on body composition is a strategy to combat obesity. Conjugated linoleic acid (CLA) due its beneficial effects on body composition and inflammatory processes becomes an interesting candidate, since the promotion and impairment of obesity is closely linked to a low-grade inflammation state of adipose tissue. Previously we reported the favourable effects of moderate doses of CLA mixture on body composition and inflammatory status of adipose tissue in mice fed a standard-fat diet. In the present study we assessed the potential beneficial effects of CLA mixture (cis-9, trans-11 and trans-10, cis-12, 50:50) in mice fed a high-fat diet. Two doses were assayed: 0.15 g (CLA1) and 0.5 g CLA/kg body weight (CLA2) for the first 30 days of the study and then animals received a double amount for another 35 days. The lowest dose (CLA1) had minor effects on body composition, plasma parameters and gene expression. However, a clear reduction in fat
Outrageous, right? What? Well, the title of this post. I mean even the use of the term low fat advantage is probably going to piss a couple of people off, these days. So, please low carb crusaders, dont kill the messenger, it was not my idea to put 32 obese subjects (mean age 43y) onto alternative day fasting regimen that provided either 45% (ADF-HF) or just 25% (ADF-LF) of the energy in form of fat (25% fat) and to observe what happens to their almost 50% fat (46kg of pure fat on 96kg of total body weight) bodies during a 2-week baseline weight maintenance period and an 8-week alternative day fasting weight loss period, in the course of which all foods were provided by the research team at the Department of Kinesiology and Nutrition of the University of Illinois at Chicago (Klempel. 2013 ...
IMPACT OF BODY COMPOSITION ON PHYSICAL PERFORMANCE TASKS IN OLDER OBESE WOMEN UNDERGOING A MODERATE WEIGHT LOSS PROGRAM. G.D. Miller, S.L. Robinson. J Frailty Aging 2013;2(1):27-32. Show summaryHide summary. Background: Although obesity is a recognized risk factor for impaired physical function in older adults, there is still debate on whether older obese adults should undergo intentional weight loss due to concern of loss in lean body mass, including appendicular lean soft tissue mass. This may put them at risk for worsening muscle strength and mobility. Objectives: Therefore, the purpose of this study was to examine the effect of a weight loss intervention on body composition and physical function in obese older women. Design: Women were randomized into either a weight stable (WS) (n=20) or an intensive weight loss (WL) (n=26) group. Setting: The study setting was at a university research facility. Participants: Women (age, 67.8±1.3 yrs; BMI, 34.9 (0.7) kg/m2; mean±standard error of the ...

Disease states can adversely affect body composition and energy expenditure. Resting energy expenditure decreases following prolonged starvation in the absence of any organic disease.21 This is a biological response to conserve energy. It has previously been shown that, in malnourished patients with anorexia nervosa, the REE per unit of lean tissue is reduced.22 Our study confirms this finding. We regard anorexia nervosa as a model for prolonged (semi)starvation22 without any associated organic disease. Certainly our earlier results22 are consistent with those in subjects undergoing prolonged starvation on a voluntary basis.21 We therefore chose to compare two groups of malnourished patients-anorexia nervosa, in which there is voluntary food restriction, and Crohns disease, an inflammatory process with weight loss. The patients with Crohns disease were also moderately malnourished at the time of exacerbation. In body compartments, lean body mass was significantly depleted. As a proportion of ...
Nutritional status is an important factor influencing outcomes in persons undergoing hematopoietic stem cell transplantation (HSCT). While quantitative measurements such as body mass index (BMI) and weight change and serum markers such as albumin are commonly used in the pre- and post-transplant evaluations, these parameters in isolation give an incomplete understanding of overall health status. A more comprehensive evaluation of body composition and its relation to functional status pre- and post-transplant would facilitate the implementation of interventions aimed to improve outcomes in transplant recipients.. Prior studies of allogeneic transplant recipients have identified low BMI, low body weight, or weight loss during transplant as measurements of nutritional status correlating with inferior clinical outcomes.1 Low pre-transplant BMI ,18.5 kg/m2 has been associated with worse survival, higher treatment-related mortality and in some instances higher risk of disease relapse.2 Other studies ...
Most people are familiar with the biomedical diagnostic application of ultrasound (US), such as musculoskeletal injury evaluation and visualization of a fetus during a prenatal exam [1]. Despite being used to measure fat thickness in humans dating back to the mid-1960s [2, 3], using ultrasound for body composition assessment has been customarily overshadowed by other techniques [1]. In a recent survey of national and international sport professionals by Meyer et al. (2013), ultrasound (US) was so seldom used that it didnt even make the list of common body composition techniques [4]. On the other hand, skinfolds assessment, a technique that provides many similar advantages to US (small, portable, quick, regional assessment, etc.), was the most popular kid in class [4]. US = Ultrasound. Using a beam of skin-penetrating ultrasonic waves (i.e. high-frequency sound waves above the upper limit of human hearing) emitted by a transducer probe, body fat percentage is estimated based on the acoustic ...
Background The background of most metabolic diseases is obesity and overweight. The purpose of this study was to compare the relationship between resting metabolic rate and body composition factors in obese and normal-weight gymnast children. Materials and Methods In this semi-experimental study, 20 obese and 21 normal-weight boys age 8 to 12 year old participated in the study. In the first session, anthropometrical (weight, height, waist to hip ratio (WHR), and body composition [(body fat percentage (BF%), body fat weight (BFW), and lean body weight (LBW)] data were measured. In the next session, at first, subjects rested for 15 min and then performed a modified Bulk exhausting test. The subjects were connected to the mouthpiece of gas analyzer throughout the rest and exhausting test andthemaximal oxygen consumption (VO2max), respiratory exchange ratio (RER), and resting metabolic rate (RMR) was measured in both groups. Results A significant difference was observed for a mean of VO2max, weight,

Low-carbohydrate, high-fat and ketogenic diets are increasingly adopted by athletes for body composition and sports performance enhancements. However, as yet, there is no consensus on their efficacy in improving performance. There is also no comprehensive literature on athletes experiences while undertaking this diet. The purpose of this pilot work was two-fold: i. to examine the effects of a non-calorie controlled ketogenic diet on body composition and performance outcomes of endurance athletes, and ii. to evaluate the athletes experiences of the ketogenic diet during the 10-week intervention. Using a case study design, five New Zealand endurance athletes (4 females, 1 male) underwent a 10-week ketogenic dietary intervention. Body composition (sum of 8 skinfolds), performance indicators (time to exhaustion, VO2 max, peak power and ventilatory threshold), and gas exchange thresholds were measured at baseline and at 10 weeks. Mean change scores were calculated, and analysed using t-tests; Cohens

Studies over the past 10 years strongly support an association between skeletal muscle mass (SMM) depletion and outcome in metastatic colorectal cancer (mCRC). Factors influencing SMM changes over time are, however, poorly studied. We analyzed the impact of SMM on overall survival and chemotherapy toxicities in mCRC patients treated with first-line chemotherapy. Changes in weight and body composition were evaluated during follow-up. Patients enrolled in the randomized phase II ACCORD trial comparing two chemotherapy regimens were screened. Body composition parameters (SMM, adipose tissue) were assessed prospectively with computed tomography (CT) imaging, and toxicities were recorded. Mixed models were used to assess weight and BC changes during 4 months of treatment follow-up. Among 145 patients included in ACCORD, 76 had available baseline CT scans and were included in the current study. Mean age was 60.6 ± 10.0 years, 50% were women, 82% had colon cancer, and 62% had two or more metastatic sites. At

World J Hepatol 2017 March 8; 9(7): 401-408. Background: To evaluate the prognostic value of the phase angle (PA) obtained from bioelectrical impedance analysis (BIA) for mortality prediction in patients with cirrhosis.. Subjects /Methods: In total, 134 male cirrhotic patients prospectively completed clinical evaluations and nutritional assessment by BIA to obtain PAs during a 36-mo follow-up period. Mortality risk was analyzed by applying the PA cutoff point recently proposed as a malnutrition marker (PA≤ 4.9°) in Kaplan-Meier curves and multivariate Cox regression models.. Results: The patients were divided into two groups according to the PA cutoff value (PA , 4.9°, n = 73; PA ≤ 4.9°, n = 61). Weight, height, and body mass index were similar in both groups, but patients with PAs , 4.9° were younger and had higher mid-arm muscle ...
A persons body weight is made up of different components (Muscles, bone, fats, tissues).It all adds up to form an individuals body composition. Two people who have the same body weight and height may look completely different from one another because of their differing body composition. The weighing scale can only tell you how heavy you are but it does not give you a breakdown of your body fat percentage and lean muscle mass. According to the National Institute of Health, the healthy range for body fat should be between 8-17% for male and 10-21% for female. Any figure that is above the range stated is considered excess body fat.. There are many ways which you can measure your body fat percentage. One of the most common method is to use a skinfold caliper. The caliper used is precisely calibrated to ensure accuracy of the measurements.. Different measurement readings are taken from specific points on the body. All measurements are taken on the right side of the body. The results are used to ...
Background: Roux-en-Y gastric bypass (RYGB) result in a marked reduction of body fat and also visceral fat (VF) decrease up to 36 % in 16 weeks. This leads to positive effects on cardiometabolic risks, which are known to be correlated with the occurrence of VF. This study analyzed the validity of bioelectrical impedance analysis (BIA) for determining VF in the postoperative course. In addition, magnetic resonance imaging (MRI) was performed for prediction of whole VF in bariatric patients on the basis of a single slice. Methods: Eighteen patients, who underwent RYGB (18), were included in this study. MRI and BIA measurements were performed 1 day before surgery, as well as 6, 12, and 24 weeks after surgery. Results: During the postoperative observation period, we found a significant decrease of both subcutaneous fat (SF) and VF. SF measured by MRI was highly correlated with the level of body fat shown by BIA. In contrast, the VF volume, as determined by MRI, showed no correlation with the body ...
Electrical bioimpedance measurement is widely used today for monitoring body condition. The applications include and go beyond, body composition assessment, nutritional status evaluation, and cancer detection. The modalities for interpreting the impedance information have also developed quickly over the recent decades from single frequency bioimpedance analysis to spectrum and to images.. Bioimpedance is measured by computing the relationship between voltage and current. In a current based bioimpedance measurement system, the stability of current source has a large influence on the performance of the system. This thesis compared three different voltage controlled current sources: enhanced Howland circuit, load-in-the-loop circuit driven by a current conveyor and double operational amplifiers circuit. These circuits were simulated in Multisim and manufactured into prototypes and tested in lab.. Effort has also been made to generate and collect signals with digital-to-analog convertor and ...
A method and apparatus for rapid non-invasive determination of blood composition parameters. A blood-containing body part of a live organism is irradiated with electromagnetic radiation of near-infrared wavelength range. Spectrum values of the radiation transmitted through and reflected by the body part are measured. One or more unknown values of blood composition parameters are determined on the basis of the measured values. The transmittance spectrum of the body part is measured at several wavelengths in a first wavelength range from 700 nm to a value between 1000 and 1100 nm. The reflectance and/or interactance spectrum of the body pat is measured at several wavelengths in a second range from the value between 1000 and 1100 nm to 1800 nm. The unknown values of blood composition parameters are determined on the basis of a single spectrum including spectrum values of said transmittance spectrum and spectrum values of said reflectance and/or interactive spectrum.

Smartphones can be used to estimate body composition and indicate health and mortality risks, according to a new study by a University of Hawaiʻi Cancer Center researcher and his team. This accessible and cost-effective option will enable early screening and monitoring of physiological indicators of metabolic diseases in regions where medical imagery or clinical assessment is not available.. This is beneficial as smartphones are already owned by middle and low-income individuals who are most susceptible to metabolic diseases, including diabetes and non-alcoholic fatty liver disease, said John Shepherd, lead study investigator.. Patients health and mortality risks can be indicated by total and regional body composition measurements using 3-D imaging, which require expensive and specialized equipment and are restricted to clinical settings. The study found that body composition can be estimated from a single frontal consumer level photograph of a patients body that can be taken on ...

The psychiatric condition of patients suffering from anorexia nervosa (AN) is affected by their nutritional status. An optimal assessment of the nutritional status of patients is fundamental in understanding the relationship between malnutrition and the psychological symptoms. The present review evaluates some of the available methods for measuring body composition in patients with AN. We searched literature in Medline using several key terms relevant to the present review in order to identify papers. Only articles in English or French were reviewed. A brief description is provided for each body composition technique, with its applicability in AN as well as its limitation. All methods of measuring body composition are not yet validated and/or feasible in patients with AN. The present review article proposes a practical approach for selecting the most appropriate methods depending on the setting, (i.e. clinical v. research) and the goal of the assessment (initial v. follow-up) in order to have a ...
