Scaling of body composition to height: relevance to height-normalized indexes.
BACKGROUND Body weight scales to height with a power of ≈2, thus forming the basis of body mass index (weight/height(2)). The corresponding scaling of body composition to height has not been established in a representative sample of US adults. OBJECTIVE The aim of the study was to examine the scaling of weight, fat, fat-free mass, and bone mineral content to height. DESIGN Adult non-Hispani...
متن کاملBody mass index and body composition scaling to height in children and adolescent
Childhood obesity prevalence has been increased and known to be related to various diseases and mortality in adult and body mass index (BMI) has been widely used as a screening tool in children with obesity. It is important to understand what BMI is and its limitations. BMI is a measure of weight adjusted for height. Weight scales to height with a power of about 2, is the basis of BMI (weight/h...
متن کاملThe Influence of Height Ratio on Rayleigh-number Scaling and Stability of Horizontal Convection
Horizontal convection in a rectangular enclosure driven by a linear temperature profile along the bottom boundary is investigated numerically using a high-resolution spectralelement discretization in space and a third-order time integration scheme for velocity and temperature fields. A Boussinesq approximation is employed to model buoyancy. The emphasis of this study is on the scaling of Nussel...
متن کاملScaling of human body mass with height: the body mass index revisited.
We adapt a biomechanical argument of Rashevsky, which places limits on the stress experienced by a torso supported by the legs, to deduce that body mass m of growing children should scale as the p th power of height h with 7/3 < p < 8/3. Further arguments based on stability and heat loss suggest that p should be close to 8/3. The arguments are extended to suggest that waist circumference w shou...
متن کاملScaling of adult body weight to height across sex and race/ethnic groups: relevance to BMI.
BACKGROUND Body mass index (BMI) is formulated on the assumption that body weight (BW) scales to height with a power of 2 (BW∝height(2)), independent of sex and race-ethnicity. Powers differing from 2 are observed in studies of selected samples, thus raising the question if BMI is a generalizable metric that makes BW independent of height across populations. OBJECTIVES The objectives were to ...
