BACKGROUND Low fat-free mass may be an independent risk factor for malnutrition that results in an increased length of hospital stay (LOS). OBJECTIVES The objectives were to compare differences in fat-free mass and fat mass at hospital admission between patients and healthy control subjects and to determine the association between these differences and the LOS. DESIGN Patients (525 men, 470...

objective: nowadays the value of bioelectrical impedance analysis (bia) in the estimation of body adiposity both on a clinical basis in the individual and epidemiologically in large populations is of great interest. the current study determine accuracy of bia compared with body mass index (bmi) measurement for estimating body composition in a group of normal weight employee women with a sedenta...

Background: Differences in body composition are extensively investigated in subjects with COPD as low muscle mass was independently associated with increased morbidity and mortality. Also cardio-vascular co-morbidity is often reported in COPD and the contribution of fat mass in COPD related co-morbidity is gaining interest. We hypothesized that the prevalence of low muscle mass and high fat mas...

Physical fitness is a powerful marker of health in youth. Studies in adolescents and adults suggest that higher fat mass is related to worse physical fitness. However, there is limited knowledge whether fat mass and fat-free mass are associated with physical fitness already in preschoolers. Baseline data from the MINISTOP (Mobile-based INtervention Intended to STop Obesity in Preschoolers) tria...

OBJECTIVES To develop reference curves for the body fat index (BFI) in the pediatric population, in adolescents from the city of São Paulo, Brazil, and verify their association with body mass index and body fat percentage. METHODS The study is part of the research project "Nutritional Profile of Adolescents from Public and Private Schools of São Paulo" that was performed in 2004-2005. A total...

BACKGROUND low fat-free mass has been related to high mortality in patients. This study evaluated the relationship between body composition of healthy elderly subjects and mortality. METHODS in 1999, 203 older subjects underwent measurements of body composition by bioelectrical impedance analysis, Charlson co-morbidity index and estimation of energy expenditure through physical activity by a ...
