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...

Body composition, fat distribution and bone mineral density were examined in lean women suffering from polycystic ovary syndrome (PCOS) and compared with body composition and fat distribution characteristics of weight-matched lean controls. Ten women with PCOS and a body mass index (BMI) below 25.00 (kg/m(2)) and 10 healthy women with a BMI below 25.00 (kg/m(2)) matched for age and weight and B...

Background There are many types of intervention that can lead to a change in lean body mass including: hormone replacement therapy, aging, menopause, strength training, aerobic exercise, extreme weight loss interventions (gastric bypass surgery), and starvation. Lean body mass is a metabolically active tissue which is involved in several key functions in the body, including: locomotion, basal m...

Body fat and lean body mass was assessed in young college students by two different techniques involving NIR method and body circumference measurements. NIR technique significantly over-estimated the body fat as compared to the results obtained by the other method. The difference between the methods was 23-30% high for fat and the variation was 5-9% low for lean body mass for the whole group. R...

OBJECTIVES Diagnostic criteria for sarcopenia include measures of muscle mass, muscle strength and physical performance. Consensus on the definition of sarcopenia has not been reached yet. To improve insight into the most clinically valid definition of sarcopenia, this study aimed to compare the association between parameters of malnutrition, as a risk factor in sarcopenia, and diagnostic measu...

BACKGROUND Body mass index (BMI) does not make a distinction between fat mass and lean mass. In children, high fat mass appears to be associated with low maternal education, as well as low lean mass because maternal education is associated with physical activity. Therefore, BMI might underestimate true obesity in children of low-educated mothers. OBJECTIVE To investigate the associations of m...

BACKGROUND AND PURPOSE Fractures are a serious complication after stroke, and the risk of hip fractures among stroke patients is increased 2 to 4 times versus a reference population. Fractures after stroke are probably caused by the development of hemiosteoporosis and the high incidence of accidental falls. The aim of this study was to investigate the development of hemiosteoporosis in relation...

UNLABELLED Metabolic disorders are involved in the pathogenesis of some comorbid conditions such as atherosclerosis and cardiovascular diseases, which frequently occur in COPD patient. These disorders may also associate alterations in body composition. AIM To determine the particularities of body composition, assessing its relationship with respiratory function and clinical status in COPD pat...

BACKGROUND Clinical recommendation of weight loss (WL) in older adults remains controversial, partially due to concerns regarding lean mass loss and potential loss of physical function. The purpose of this study is to determine the independent associations between changes in fat and lean mass and changes in physical function in older, overweight, and obese adults undergoing intentional WL.
