Bioelectrical impedance analysis (BIA) is a simple and quick method used for assessment of body composition (BC). Present study aims to develop and validate a BIA prediction equation for Sri Lankan adults. Healthy adults (≥ 18 years) were randomly selected for development and validation of the equation. BIA was performed using the Inbody 230 multifrequency analyzer. BC analysis was also evaluated by deuterium oxide (D 2 O) dilution. Prediction equations for TBW/FFM were derived by linear-regression analysis …

Objectives Bioelectrical impedance analysis (BIA) is a simple and inexpensive method to estimate body composition. However, the accuracy of BIA is unknown. We aimed to assess the accuracy of BIA in estimating visceral fat area (VFA) in patients with gastric cancer. Study design This was a cross-sectional study comparing the accuracy of BIA in estimating VFA with the gold standard method measured by CT. VFA was measured in enrolled patients both by CT and BIA. VFA by CT at umbilical level≥ 100 cm 2 was considered as visceral …

The purpose of this study was to validate a Bioelectrical Impedance Analysis (BIA) equation for prediction of Bone Mineral Content (BMC) against Dual energy X-ray Absorptiometry (DXA) in Indian adults. Healthy 113 subjects were investigated by two methods: BMC was measured by DXA and bioelectrical impedance at various frequencies was measured by a commercial segmental multi-frequency BIA instrument. Body parameters were derived from impedance data and a new BIA equation was developed for the estimation of BMC, which …

The aim of the study is to examine the validity in predicting body fat percentage (% BF) of different bioelectrical impedance (BIA) devices among Chinese children and adolescents. A total of 255 Chinese children and adolescents aged 9–19 years old participated in the study.% BF was assessed by BIA scales, namely, Biodynamics-310 (Model A), Tanita TBF-543 (Model B), Tanita BC-545 (Model C), and InBody 520 (Model D). Dual-energy X-ray absorptiometry (DXA) was used as the criterion measurement. Lin's concordance correlation …

Multifrequency bioelectrical impedance analysis was used to estimate the ratio of extracellular water (ECW) to total body water in subjects with end-stage renal disease. The body's resistance was measured at frequencies ranging from 1 kHz to 1 MHz. The impedance index (height2/resistance) determined at low frequency (5 kHz) correlated most closely with ECW (r= 0.886) using sodium bromide dilution as the standard of comparison. In contrast, the ratio of height squared to resistance determined at high frequency (500 kHz) …

Multifrequency bioelectrical impedance analysis (MFBIA) was used to determine the intracellular (ICW) and extracellular water (ECW) compartments in rats. Resistance and reactance were measured on various body segments with frequencies ranging from 1 KHz to 1 MHz. After initial measurements, 0.9% NaCl was injected intravenously or intraperitoneally, and changes in ECW and ICW were estimated by MFBIA. Important differences were found between segments. In the leg, estimated ECW increased in …

The purpose of this study was to compare body composition measurements taken with air displacement plethysmography (BOD POD) to eight-polar bioelectrical impedance analysis (BIA) in African American college students. The 143 subjects, aged 17–39 years, visited the participating Human Performance & Leisure Studies laboratory at North Carolina A&T State University, Greensboro, NC, United States, between June 1, 2011 and December 31, 2011. Measurements of body composition, including fat mass (FM), fat free mass (FFM), and …

Objectives: Obesity is a chronic progressive disease representing a significant health hazard and serious economic problem. As an independent risk factor it contributes to increased cardiovascular and oncologic morbidity and mortality. The IDEA study conducted in the Slovak Republic in 2017 reports that every other inhabitant in Slovakia suffers from an abdominal type of obesity. Therefore, anthropometric indica-
