OBJECTIVE To assess the predictive capacity of a recently described equation that we have termed CUN-BAE (Clínica Universidad de Navarra-Body Adiposity Estimator) based on BMI, sex, and age for estimating body fat percentage (BF%) and to study its clinical usefulness. RESEARCH DESIGN AND METHODS We conducted a comparison study of the developed equation with many other anthropometric indices r...

This study aimed to determine thresholds for percentage of body fat (BF%) corresponding to the cut-off values for overweight/obesity as recommended by the International Obesity Task Force (IOTF), using two bioelectrical impedance analyzers (BIA), and described the likelihood of increased cardiometabolic risk in our cohort defined by the IOTF and BF% status. Participants included 1165 children an...

The aim of the present study was to compare body fat percent (BF %) using single-site near-IR reactance (NIR) and dual-energy X-ray absorptiometry (DXA) in a cohort of normal-weight (BMI < 25 kg/m2) black (n 102) and white (n 71); and obese (BMI > or = 30 kg/m2) black (n 117) and white (n 41) South African women (18-45 years). NIR-derived BF % was significantly correlated with DXA-derived BF % ...

Based on data from a three-year longitudinal study, we assess the effect, according to gender, of emotional psychopathology in preadolescence on anthropometric and body composition parameters in adolescence (N = 229). Psychopathology was assessed using the Screen for Childhood Anxiety and Related Emotional Disorders, the Children's Depression Inventory and the MINI-International Neuropsychiatri...

–The aim of this study was to verify the association between inflammatory biomarkers, dyslipidemia, obesity and physical activity status in 10-years old children. Ninety-four children participated in this study and were classified into eutrophic (n=36), overweight (n=34) or obese (n=24) according to their body mass index (BMI). The genic expression of interleukin 6 (IL-6), tumor necrosis factor...

Body composition was measured in 205 male and female Beijing Chinese and in 148 male and female Singaporean Chinese, age 34 (mean) (range 18-68) years and body mass index (BMI) 22.3 (15.9-38.5) kg/m2. In Beijing Siri's two-compartment model based on densitometry was used as a reference technique and in Singapore Siri's three-compartment model based on densitometry and deuterium oxide dilution w...

Body composition methods were examined in 20 women [body mass index (BMI) 48.7 +/- 8.8 kg/m(2)] before and after weight loss [-44.8 +/- 14.6 (SD) kg] after gastric bypass (GBP) surgery. The reference method, a three-compartment (3C) model using body density by air displacement plethysmography and total body water (TBW) by H(2)18O dilution (3C-H(2)18O), showed a decrease in percent body fat (%BF...

OBJECTIVE The purpose of the present study was to examine the interactions between weight perceptions, weight control behaviours and body fatness in a multiethnic sample of adolescent girls. DESIGN A cross-sectional study. SETTING Girls from European (37.7 %), Pacific Island (21.6 %), East Asian (15.8 %), Maori (10.2 %) and South Asian (9.6 %) populations and from other ethnicities (5.0 %)....

Obesity is the major risk factor for the development of many diseases. BMI is widely used as a deputy measure of obesity, but underestimates the prevalence of obesity, defined as an excess of body fat. The aim of this study was to investigate the relationship between body mass index (BMI) and body fat percentage (BF%) in females. The study was a cross-sectional design. A selected sample of 70 f...
