Body composition in subjects with anorexia nervosa: bioelectrical impedance analysis and dual-energy X-ray absorptiometry.
OBJECTIVE To evaluate the applicability and validity of bioelectrical impedance analysis (BIA) compared with dual-energy X-ray absorptiometry (DXA) in a population of girls with restrictive anorexia nervosa (AN). METHODS A total of 30 girls (11-19 years old) with AN were enrolled. DXA and BIA (BIA software and the Deurenberg equations) were used to estimate the body composition. The correlati...
متن کاملEstimation of body composition from bioelectrical impedance of body segments: comparison with dual-energy X-ray absorptiometry.
In twenty-eight healthy subjects, ten men and eighteen women, with a range in body mass index (BMI) of 17.9-31.6 kg/m2 and an age range 20-60 years, body composition was estimated by dual-energy X-ray absorptiometry (DEXA), skinfold anthropometry (SFA) and bioelectrical impedance analysis (BIA) of the 'whole body' and body segments. In thirteen subjects muscle mass was also estimated by 24 h ur...
متن کاملRelationships among dual-energy X-ray absorptiometry, bioelectrical impedance and ultrasound measurements of body composition of swine
In three separate studies (156 pigs total), dual-energy X-ray absorptiometry (DXA), bioelectrical impedance (BIA) and ultrasound were compared as methods for measuring live body composition of pigs at 60 and 100-110 kg BWt. DXA measured total body fat and lean content, BIA measurements of resistance (Rs) and reactance (Xc) were used to calculate total body lean mass and ultrasound measurements ...
متن کاملBody Composition Analysis by Dual-Energy X-Ray Absorptiometry in Women Aged 20-75 Years
Obesity has become a worldwide epidemic [1]. Its consequences include severely increased morbidity and mortality, as well as impaired quality of life. According to recent publications, 38.8% of the men and 28.3% of the women in a random Bulgarian population (1046 women and 912 men) have overweight and obesity [2]. Common measures of overweight and obesity are the body weight, body mass index (B...
متن کاملComparison of multifrequency bioelectrical impedance analysis with dual-energy X-ray absorptiometry for assessment of percentage body fat in a large, healthy population.
BACKGROUND Bioelectrical impedance analysis (BIA) is widely used in clinics and research to measure body composition. However, the results of BIA validation with reference methods are contradictory, and few data are available on the influence of adiposity on the measurement of body composition by BIA. OBJECTIVE The goal was to determine the effects of sex and adiposity on the difference in pe...
