Obesity is a major public health problem in the United States. The role of physical activity and formal exercise in controlling body weight has not been clearly determined.
Most methods available to clinicians for estimating body-composition changes have been validated against estimates from densitometry, based on a 2-component (fat mass and fat-free mass) model.
Malnutrition is common in HIV-infected children, but the body compartment that is most affected has been ill defined.
Nondigestible oligosaccharides have been claimed to benefit the health of the colon by selectively stimulating the growth of bifidobacteria and by decreasing the toxicity of the colon contents
Body composition in children is generally measured by 2-component (2C) models, which are subject to error arising from variation in fat-free mass (FFM) composition. The 4-component (4C) model, whic...
Over the past decade, considerable attention has been paid to accurately measuring body composition in diverse populations. Recently, the use of air-displacement plethysmography (AP) was proposed a...
The assumed constancy” of fat-free body mass hydration is a cornerstone in the body-composition research field. Hydration, the observed ratio of total body water to fat-free body mass, is stable a...
Although the high prevalence of obesity in American Indian children was documented in several surveys that used body mass index (BMI, in kg/m2 ) as the measure, there is limited information on mor...
No studies have been reported in children that assess correlates of body-composition changes in response to a physical training intervention.
There is little information on whether bioelectrical impedance analysis (BIA) accurately predicts changes in body composition associated with energy restriction, exercise, or both.
Commercial enteral diets differ widely in nutrient composition. It is unknown whether the nutrient composition of the diets influences intestinal absorption.
Determination of body composition during critical illness is complex because of various patient-related and technical factors. Bioelectrical impedance is a promising technique for the analysis of b...
Cardiorespiratory fitness and body fatness are both related to health, but their interrelation to all-cause and cardiovascular disease (CVD) mortality is unknown.
Reduced energy expenditure and excessive energy intake have been hypothesized to cause obesity. New Zealanders of Polynesian origin have a higher prevalence of obesity than do those of European ori...
