AIMS (1) To validate a leg to leg bioimpedance analysis (BIA) device in the measurement of body composition in children by assessment of its agreement with dual energy x ray absorptiometry (DXA) and its repeatability. (2) To establish a reference range of percentage body fat in Hong Kong Chinese children. METHODS Sequential BIA and DXA methods were used to determine body composition in 49 chi...

Chicks divergently selected for 14-d (14H and 14L) or 42-d (42H and 42L) exponential growth rate (EGR) over five generations were used to determine correlated responses between growth at different ages and body composition. Regression coefficient estimates across five generations of selection were not significant for any line at either age for percentage total body water or protein. Genetic cor...

BACKGROUND This study investigated the associations of fitness and fatness with metabolic syndrome in rural women, part of a recognized US health disparities group. METHODS Fitness, percentage body fat, BMI, and metabolic syndrome criteria were assessed at baseline in 289 rural women with prehypertension, ages 40-69, enrolled in a healthy eating and activity community-based clinical trial for...

BACKGROUND Increasing evidence indicates that adult body composition is associated with prenatal and infancy weight gain, but the relative importance of different time periods has not been elucidated. OBJECTIVE The objective was to study the association between prenatal, early postnatal, and late infancy weight gain and body mass index (BMI), fat mass, and fat distribution in young adulthood....

1. In this study we investigated the relationship between serum leptin levels and body fat distribution in a random sample of women of widely ranging age and body mass index. Anthropometry and dual energy X-ray absorptiometry were used to measure body fat and its distribution. 2. Leptin levels (log transformed) were not significantly correlated with age, but were significantly positively correl...

Anthropometrie measures Body mass index When we speak about the prevalence of obesity in populations, we mean the fraction of people who have excess storage of body fat. ln adult men with weight in the acceptable range, the percentage of body fat is around 15-20%. ln women, this percentage is higher (about 25-30%). Because differences in weight between individuals are only partly due to variati...

OBJECTIVE The purpose of this study was to determine whether objectively measured physical activity and dietary macronutrient intake differentially predict body fat in adolescent girls with type 1 diabetes and control girls. RESEARCH DESIGN AND METHODS This study comprised 23 girls (12-19 years) with type 1 diabetes and 19 age-matched healthy control girls. At baseline, physical activity and ...
