BACKGROUND Weight restoration is a crucial element in the treatment of patients with anorexia nervosa. Therefore, the validity of different methods for measuring body composition is important. OBJECTIVE We tested the concurrent validity of hydrodensitometry (underwater weighing) and anthropometry (12 skinfold thicknesses) and assessed body composition and subcutaneous fat before and after a r...

Regression equations to predict kilograms of fat-free soft tissue (the sum of water and protein from chemical analyses) were developed from data collected on 526 steers and heifers. Straightbred animals representing Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Pinzgauer, Red Poll, and Simmental breeds of cattle contributed to the data set. Cattle ranged in slaughter weight and age...

Placental growth is a strong predictor of fetal growth, but little is known about maternal predictors of placental growth in malnourished populations. Our objective was to investigate in a prospective study the associations of maternal weight and body composition [total body water (TBW) estimated by bioelectrical impedance and fat and fat-free mass derived from upper arm fat and muscle areas (U...

BACKGROUND Weight loss may contribute to the loss of lean mass with age. OBJECTIVE The objective was to evaluate the relation between weight loss or weight gain and changes in lean mass and fat mass in older adults. DESIGN We observed changes in weight and body composition during a 4-y period in 2163 men (47%) and women (53%) aged 70-79 y in the Health, Aging and Body Composition Study coho...

The ability to quantify in vivo femoro-tibial relations in the knee holds great advantage to further patient care. There is little consensus on the optimal weight-bearing environment and measurement method for MRI assessment of in vivo knee kinematics. This study set out to establish the optimal method of measuring femoro-tibial relations in an upright, weight-bearing environment in normal indi...

Young growing rats weighing approximately 83 g were fed on diets containing kidney bean (Phaseolus vulgaris) lectin (phytohaemagglutinin, PHA) in the range of 0-0.45 g/kg body weight for 10 d to ascertain whether there was a minimum dose below which the lectin had no significant effect on body and skeletal muscle weights in comparison with pair-fed lectin-free controls. Averaged over all experi...

OBJECTIVE To evaluate the effect of tibial plateau leveling on joint motion in canine stifle joints in which the cranial cruciate ligament (CCL) had been severed. STUDY DESIGN In vitro cadaver study. ANIMALS Six canine cadaver hind legs. METHODS Radiographs of the stifle joints were made to evaluate the tibial plateau angle with respect to the long axis of the tibia. The specimens were mo...

The comparative performance of shaded and unshaded Zebu cross steers was studied in a Queensland feedlot from January to May 1992. The provision of shade gave no significant (P > 0.05) advantage in liveweight gain (182 V. 177 kg), feed conversion ratio (9.4 v. 9.8 kg of fresh feed/kg liveweight gain), carcase weight, dressing percentage, P8 rump fat, eye muscle area, saleable meat yield, meat c...

CONTEXT Anorexia nervosa and normal-weight hypothalamic amenorrhea are characterized by hypogonadism and hypercortisolemia. However, it is not known whether these endocrine abnormalities result in reductions in adrenal and/ or ovarian androgens or androgen precursors in such women, nor is it known whether relative androgen deficiency contributes to abnormalities in bone density and body composi...

PURPOSE Precise estimation of creatinine clearance in obese individuals relies on the appropriate assessment of lean body weight (LBW). Anthropometric methods of predicting LBW have not been validated in morbidly obese populations. PATIENTS AND METHODS Using an existing dataset of anthropometric data for a female cohort with morbid obesity who had undergone measured FFW with dual energy absor...
