We evaluated the concordance between visceral fat area (VFA) estimated by bioelectrical impedance analysis (BIA) or computed tomography (CT) in Korean subjects with a wide range in age and body mass index (BMI). In 1006 individuals (mean age 55.2±11.8 (19–87) years, mean BMI 26.0±3.5 (17–46) kg/m 2, 48.9% men), VFA quantified by CT was compared with VFA using multifrequency BIA machines within 15 days. Concordance rates were compared by age or BMI using correlation analysis, Bland-Altman plots, and intraclass …

Visceral fat accumulation is a risk factor for cardiometabolic diseases. Magnetic resonance imaging (MRI) and computed tomography (CT) provided the most accurate techniques of abdominal fat assessment, but these methods are very expensive. The aim of this study was to examine and compare the predictive ability of simple anthropometric parameters for visceral fat area (VFA) among adult women in different age and obesity status groups. The sample consisted of 133 adult women (aged 18–76 years). All subjects underwent …

Introduction: The purpose of this study was to compare two common laboratory methods of body composition assessment: dual-energy X-ray absorptiometry (DXA) and the InBody® 270 Body Composition Analyzer. Methods: Eighty-eight subjects (43 female, 45 male) volunteered for this study. Participants were tested in a controlled laboratory environment (ie, 3-hour fast, no prior exercise, testing between 1100 and 1700 hours) first on the InBody® 270 followed by the DXA. A paired t-test was used to assess differences between the …

This study aimed to assess the association between urinary concentrations of chlorophenols and childhood central obesity. The study subjects were 165 girls (91 with central obesity and 74 with non-central obesity) aged 7–8 years who visited a hospital for regular health check-ups. The urinary concentrations of chlorophenols including 2, 4-dichlorophenol (2, 4-DCP), 2, 5-dichlorophenol (2, 5-DCP), 2, 4, 5-trichlorophenol (2, 4, 5-TCP), and 2, 4, 6-trichlorophenol (2, 4, 6-TCP) were analyzed using liquid chromatography-tandem mass …

Increasing central blood pressure is an independent predictor of cardiovascular disease and is an acute effect of high-intensity resistance exercise. It has been shown that classical music suppresses increased peripheral pressure during exercise. We hypothesized that classical music would suppress increased central pressure induced by high-intensity resistance exercise. To confirm this hypothesis, we examined the effect of classical music on central pressure following high-intensity resistance exercise in 18 young men. A …

BACKGROUND: The present study seeks to assess the validity of the InBody 520™ device to predict RMR in apparently healthy adults relative to a metabolic cart (the standard, yet time-intensive, method for determining resting metabolic rate). METHODS: Twenty-six apparently healthy adults participated in the study. Predicted RMR (pRMR) was calculated by the InBody 520™ and measured RMR (mRMR) was determined by 30-minute gas analysis and ventilated hood system. Of the 78 measurement trials conducted, 64 yielded …

BACKGROUND/AIMS: This study was conducted to assess the efficacy of bioelectrical impedance analysis by InBody 720 as a new tool for measuring visceral fat area. METHODOLOGY: A total of 53 consecutive patients elected to undergo surgical resection of primary gastric cancer received preoperative measurement of visceral fat area at the umbilical level with both computed tomography and bioelectrical impedance analysis by InBody 720. RESULTS: Visceral fat area values measured by InBody 720 significantly …

Background: At present, the portfolio of devices using the bioelectrical impedance (BIA) method is continuously expanding as a result of the wide use of this method in the field as measurements by this method are fast and staff training is simple and reasonably priced. Nonetheless, the problem is that despite using the same method, bioimpedance analyzers can differ in many parameters. They use different electric current frequencies, a different number of electrodes and the electric current may be conducted through different parts of the …

Bioelectrical impedance analysis (BIA) models must be validated against a reference method in a representative population sample before they can be accepted as accurate and applicable. The purpose of this study was to compare the eight-electrode BIA method with DEXA as a reference method in the assessment of body composition in Korean adults and to investigate the predictive accuracy and applicability of the eight-electrode BIA model. A total of 174 apparently healthy adults participated. The study was designed as a cross-sectional …
