Growth performance, body composition, body conformation and meat quality were evaluated in crossbred pigs originating from three sire lines selected for leanness and conformation. The crossbred P, which was based on Belgian Piétrain had a leaner carcass and a better ham conformation compared to the other crossbreds. The presence of the halothane gene resulted in poorer meat quality in compariso...

OBJECTIVE We measured insulin sensitivity with euglycemic clamp (Si-clamp) in initially normoglycemic African Americans (AA) and European Americans (EA), to probe the existence of subphenotypes of obesity and leanness, and their impact on incident dysglycemia during longitudinal follow-up. RESEARCH DESIGN AND METHODS 320 healthy subjects (176 AA, 144 EA; mean age 44.2±10.6 years) underwent ba...

A large amount of epidemiological evidence suggests that the impact of body weight on breast cancer risk should be heterogeneous throughout the life-stage of women. At birth, high weight has been positively associated with an increased risk of breast cancer. While, the body mass index (a relative body weight; BMI kg/m(2)) has been inversely associated with breast cancer risk among pre-menopausa...

Specific causes of death were analyzed for 10,908 participants in the Hypertension Detection and Follow-up Program, to explore possible explanations for the observed excess 8.3-year mortality from all causes in hypertensives with low body mass. Although the cardiovascular mortality rate among men in the lowest decile of body mass (body mass index 21.96 or less) was 50% higher than that of men i...

From the standpoint of promoting leanness, exercise is of most value if oxidation of stored fat is maximized during and following the exercise sessions. Bahadori has proposed that this can best be achieved if prolonged exercise of moderate intensity is performed during a 12-14 h "mini-fast" that entails skipping a meal; if subsequent food consumption features low-fat foods, the fat stores expen...

STUDY OBJECTIVES An inverse relationship between body mass index (BMI) and the risk of lung cancer, suggesting that leanness is a risk factor for lung cancer, has been reported in previous studies. In order to evaluate the risk of lung cancer associated with lower levels of BMI in preclinical patients, we conducted a case-control study based on the results of community mass screening. DESIGN ...
