Background. Body composition measurement is very important for early nutritional care in hemodialysis patients. Dual-energy X-ray absorptiometry (DXA) is a gold standard test, but clinically limited. Bioelectrical impedance analysis (BIA) with multifrequency technique is a practical and reliable tool. Objective. This cross-sectional study was aimed to compare the agreement of BIA with DXA in measurement of body composition in hemodialysis patients and to evaluate their associated factors. Methods. Body composition was measured by 2 BIA …

Introduction: The purpose of this study was to compare three body composition methods in a cohort of exercise-trained men and women: dual energy x-ray absorptiometry (DXA), a multifrequency bioelectrical impedance (MF-BIA) device (InBody® 270) and the Omron handheld BIA. Methods: Subjects (n= 47; 22 male, 25 female) came to the laboratory for body composition assessment (ie, percent body fat, fat-free mass and fat mass). Results: There were no statistically significant differences between the InBody 270 and DXA for any …

This study examined the agreement between 2 segmental bioimpedance analysis (BIA) devices, air displacement plethysmography (BOD POD), and dual energy X-ray absorptiometry (DXA) for estimating body composition in obese adults. Fifty obese adults (25 men and 25 women; age= 34.20±11.19 years; BMI= 36.14±5.33 kg/m 2) had their body fat percentage (BF%) and fat-free mass (FFM) evaluated with 2 segmental BIA devices (InBody 230 and InBody 720), BOD POD, and DXA (Lunar iDXA). Body composition via the BOD …

Body composition is an integral component of physiology and pathology, as well as an indication of how the musculoskeletal system changes over time in response to training and/or nutritional modifications. Two common methods of estimating body composition …

The objectives of this study were 1) to quantify the differences in body densities and percent body fat using various methods for evaluating body composition (eg, underwater weighing (UWW), air displacement plethysmography (ADP), skinfold caliper (SKF) measurement, ultrasound (US), bioelectrical impedance analysis (BIA), and dual-energy x-ray absorptiometry (DXA)), and 2) to examine the relationship between trends of the differences in body density and percent body fat obtained by these methods and characteristics of …

Objectives: The accuracy of different bioelectrical impedance analysis (BIA) devices for assessing body composition in children with obesity is unclear. We determined the relative accuracy of 2 BIA devices compared to dual x-ray absorptiometry (DXA) in obese and severely obese children. Methods: We measured body composition in a cross-sectional study of 78 obese children by a handheld single frequency tetrapolar BIA device (Omron), a stationary multifrequency octopolar BIA device (InBody 370) and DXA. Intermethod …

Background We compared the evaluation of skeletal muscle mass (SMM) using the computed tomography (CT) and bioelectrical impedance analysis (BIA) methods in critically ill patients. We also evaluated whether BIA can be applied for measuring SM with high accuracy to critically ill patients. Methods We included 135 critically ill surgical patients (83 men and 52 women, mean age: 59.3 years) who got the BIA and abdominal CT scan both within 7 days during the intensive care unit (ICU) stay. With CT scan, skeletal muscle area …

The purpose of this study was to evaluate the validity of whole body percent fat (% BF) and segmental fat-free mass (FFM) using multi-frequency bioelectrical impedance analysis (MF-BIA) and dual-energy x-ray absorptiometry (DEXA) in college-aged adults. Sixty-two participants male (n= 32) and female (n= 30) completed MF-BIA and DEXA measurements following established pre-test guidelines.% BF and segmental FFM (right arm, left arm, trunk, right leg, and left leg) were collected and analyzed. The MF-BIA significantly (p< 0.05) …

Objective The purpose of this study was to compare body composition measurements estimated by multi‐frequency bioelectrical impedance analysis (MF‐BIA) with air displacement plethysmography (ADP) in individuals with obesity. Methods Bariatric patients were recruited from Geisinger's Center for Nutrition and Weight Management Clinic in Danville, Pennsylvania. Sixty‐two participants (age= 52.4±9.3 years; body mass index= 38.9±8.0 kg m− 2) reported for a same‐day testing visit. Body composition was measured …

One of the major challenges in field research has been the difficulty to adequately measure body composition, such as% body fat and fat-free mass (FFM). Therefore, the purpose of the present study was to investigate the convergent validity of the portable bioelectrical impedance body composition analyzer, the Inbody 230, with dual X-ray absorptiometry (DXA)(General Electric Lunar Prodigy). The study population consisted of 145 men and women (age, 44.6±20 years; BMI, 24.5±3.8 kg· m–2). We measured body composition (fat …
