Body Weight and Diabetes

JAMA: The Journal of the American Medical Association, 1983
To the Editor.— The findings reported by O'Sullivan inThe Journal(1982; 248;949) that body weight in patients with normal gestational glucose tolerance test results is not related to diabetes have a serious flaw. With only 66 obese subjects in the normal control group, the author had only a 12% chance to detect a relationship between relative weight ...

Body weight, heart weight, and heart-to-body weight ratio in Greyhounds

American Journal of Veterinary Research, 1995
SUMMARY Heart and body weights were obtained from 230 Greyhounds during necropsy. Sex and age were recorded for each Greyhound. Twenty-nine racing and 21 nonracing Greyhounds among the 230 dogs were compared. Heart-to-body weight ratio was calculated.

Effect of clothing weight on body weight

International Journal of Obesity, 2012
In clinical settings, it is common to measure weight of clothed patients and estimate a correction for the weight of clothing, but we can find no papers in the medical literature regarding the variability in clothing weight of adults with weather, season and gender.Fifty adults (35 women) were weighed four times during a 12-month period with and ...

Body Weight and Longevity [PDF]

open access: possibleJAMA, 1987
Conflicting results have been reported concerning the association between body weight and longevity. The shape of the curve relating weight to all-cause mortality has been variously described as linear, J-shaped, and even U-shaped. To assess the validity of the evidence for optimal weight recommendations, we examined the 25 major prospective studies on

Lipectomy, Body Weight, and Body Weight Set Point in Rats

Physiology & Behavior, 1999
Adult, Wistar male rats were lipectomized or sham lipectomized. The food-hoarding behavior was measured repeatedly and plotted against the animals' body weights. Body weight set point was estimated as the intercept of regression line of hoarding with the X axis. Body fat content was measured with a TOBEC body composition analyzer. Body weight set point,

Body Weight and Mortality

Nutrition Reviews, 2009
Over the years ideal or desirable weights have been associated with the lowest mortality and defined in a number of ways. The widely used height-weight tables of the Metropolitan Life Insurance Company, developed in the 1940s, have been supplanted in the last decade by new weight standards based on findings of several population-based studies that ...

Muscular development and lean body weight in body builders and weight lifters

Medicine & Science in Sports & Exercise, 1980
The extent of extreme muscular development in 39 males identified as body builders (N = 18), power weight lifters (N = 13), and Olympic weight lifters (N = 8) were studied. Body composition and anthropometric data, including calculations of pre-excess muscle body weight (scale weight minus excess muscle) were obtained.
