Validity of Two Commercial Grade Bioelectrical Impedance Analyzers for Measurement of Body Fat Percentage. JEPonline 2013; 16 (4): 74-83. The purpose of this study was to validate the assessment of% Fat measured by two commercial grade BIA devices against the gold standard of dual x-ray absorptiometry (DEXA). Twenty-one subjects were measured for% Fat using three devices: an octopolar, multi-frequency BIA device (BIA8, BioSpace InBody R20); a quadripolar, single frequency BIA device (BIA4, Tanita BC-590BT); and a …

Purpose: The purpose of this study was to test the convergent validity of Omron 306 using Biospace InBody 720. Method: A total of 267 participants (145 boys; aged 10.4–17.9 years) completed testing during a single session. Each measure provided percent body fat (% BF), while the InBody 720 included fat-free mass (FFM). The validity was examined using the Pearson correlation. Limits of agreement (LOA) and multiple linear regression were also used to determine the impact of both age and FFM on the associations between the 2 …

We tested the validity and reliability of the BioSpace InBody 320, Omron and Bod-eComm body composition devices in men and women (n 254; 21–80 years) and boys and girls (n 117; 10–17 years). We analysed percentage body fat (% BF) and compared the results with dual-energy X-ray absorptiometry (DEXA) in adults and compared the results of the InBody with underwater weighing (UW) in children. All body composition devices were correlated (r 0· 54–0· 97; P≤ 0· 010) to DEXA except the Bod-eComm in women aged 71–80 years (r 0 …

The aim of this study was to determine reference values for sarcopenia indices using different methods in healthy Saudi young men. Participants included 232 Saudi men aged between 20 and 35 years. The study measured anthropometric indices, blood pressure, hand grip strength, and lean muscle mass using dual-energy X-ray absorptiometry (DXA), and bioelectrical impedance analysis (BIA) was performed using Inbody 770 and Tanita 980 devices. Using DXA, the mean value of appendicular lean mass divided by the height …

Objective: This study evaluated the impact of feet callosities, arm posture, and use of electrolyte wipes on body composition measurements by bioelectrical impedance analysis (BIA) in morbidly obese adults. Methods: 36 morbidly obese patients (13 males, aged 28-70 years, BMI 41.6±4.3 kg/m 2) with moderate/severe feet callosities participated in this study. Body composition (percent body fat (% BF)) was measured while fasting using multi-frequency BIA (InBody 720®), before and after removal of callosities, with and without …

The aim of this study was to determine the most effective anthropometric equations or BIA devices for quantifying the sensitivity to change in fat free mass (FFM) in elite young soccer players, in comparison with measurement using dual-energy X-ray absorptiometry (DXA), between pre-season and mid-season. A total of 40 elite youth soccer players participated in this study. DXA values provided a criterion measure of FFM. Correlation coefficients, biases, limits of agreement, and differences were used as measures of sensitivity to change. All …

Besides magnetic resonance imaging, dual energy X-ray absorptiometry (DXA) seems the most reliable tool to evaluate body composition and is often considered as the gold standard in clinical practice. Bioelectrical impedance analysis (BIA) could provide a simpler, portative, and less expensive alternative. Because the body composition assessment by BIA is device-dependent, the aim of this study was to appraise the concordance between the specific bioelectrical impedance device InBody S10 and DXA for the body composition evaluation …

ABSTRACT Background: New, vertical, 8-electrode bioimpedance spectroscopy (BIS) analyzers provide detailed body-composition and nutritional information within 2 min. This is the first report on BIS's accuracy in predicting relative fatness [percentage body fat (% BF)] in a heterogeneous sample according to a multicomponent model criterion. Objective: We compared% BF measurements from 2 BIS devices with those from a multicomponent model in a sample of Hispanic, black, and white adults. Design: Equal numbers of apparently …

Objectives To compare the accuracy of abdominal visceral fat area (VFA) measurements between abdominal dual bioelectrical impedance analysis (BIA) and whole-body BIA referenced to computed tomography (CT) measures. Methods Abdominal VFAs were measured in 102 individuals: 59 men and 43 women with a mean age of 44.2±16.3 years (range 21–76), body mass index 23.9±7.8 kg/m 2 (range 18–35) using a DUALSCAN HDS-2000 machine (dual abdominal BIA) and an InBody720 machine (whole-body BIA). The VFA …

Background: In diagnosis and treatment of obesity, body composition analysis including percent body fat (% BF) is useful in the clinical setting. Because bioelectrical impedance analysis (BIA) could be used quickly, easily and was non‐invasive in clinical setting, the purpose of the present study was to evaluate the usefulness of multi‐frequency BIA with eight‐point tactile electrodes (MF‐BIA8; InBody 720, Biospace) compared with dual‐energy X‐ray absorptiometry (DXA) in healthy children and adolescents. Methods: A total of 166 …
