Obesity is a global problem that is reaching epidemic proportions. Body composition is an important parameter for humans because previous studies indicate high values of body fat as a predictor of mortality. The aim of the study was to assess gender differences in body composition and physical fitness in Saudi adult population. This epidemiological cross-sectional study included 411 healthy adu...

The relationship between insulin resistance (HOMA-IR), percent body fat, and aerobic fitness (VO2max per unit fat free mass; mL/kgFFM/min) was examined in 1,710 children. Percent body fat was estimated from sum of skinfolds, and VO2max was estimated from submaximal cycle ergometer tests. Overnight fasting blood samples were obtained. VO2max (mL/kgFFM/min) and percent body fat were correlated wi...

Obesity, along with other unhealthy living habits, nowadays represents one of the greatest risk factors for various diseases. This study was designed to define the most suitable anthropometric technique among body mass index (BMI), waist-hip ratio (WHR) and Body fat percent (BF) as indices of obesity in women living in Raipur City. The study was a cross-sectional design. A selected sample of 70...

OBJECTIVE Diabetes mellitus requires lifelong treatment, most of which is accomplished in family and community settings. The present study was designed to identify the effectiveness of nutrition intervention provided by public dietitian on glycemic control in a community setting in China. METHODS Two communities were selected and randomly assigned to a routine care group (59 subjects) and a p...

Results Using multiple linear regression, a model was produced where significant predictors of VO2max (p < 0.05) included estimated body fat percentage from sum of three skinfolds (p < .001) and BMI (p = .024). The generalized equation (R = .741, R2 = .549, SEE = 7.10) derived from the model to predict VO2max was: 72.32 + (-.949 × %fat from skinfolds) – (.392 × BMI). Variables excluded (p > 0.0...

We determined whether ultra-runners in a multi-stage ultra- endurance run lose body mass, fat mass, skeletal muscle mass or total body water in a descriptive field study at the 'Deutschlandlauf' 2007 a 1,200 km run within 17 consecutive days with 10 male non-professional Caucasian ultra-runners (mean ± SD, 43.8 ± 6.2 years, 73.8 ± 6.0 kg body mass, 1.77 ± 0.05 m body height, BMI 23.3 ± 1.8 kg·m...

The aim of this study is to investigate the relationship between sleep duration and body composition and to estimate the genetic contribution of sleep duration and body composition in a Chinese twin population. This cross-sectional analysis included 738 men and 511 women aged 21-72 year. Anthropometric and dual-energy X-ray absorptiometry (DXA) measures of body composition were used. Sleep dura...

OBJECTIVE The purpose of this cross-sectional study was to establish neighborhood built environment correlates of adiposity as measured by dual x-ray absorptiometry (DXA). The utility and methodological gains of using this measure for built environment research was further investigated by comparing model fit across parallel models on BMI z-scores and waist circumference. METHODS Pre-existing ...
