Impact of the Visceral Fat Area Measured by Dual Impedance Method on the Diagnostic Components of Metabolic Diseases in a Middle-aged Japanese Population

Abstract

Objective The aim of this study was to examine the associations between the visceral fat area (VFA) and the subcutaneous fat area (SFA) as estimated by the dual impedance method with a body composition monitor (BCM) and the diagnostic components of metabolic syndrome in a middle-aged Japanese population. Methods The subjects included 303 men (average age 51.3±9.0 years old) and 345 women (average age 40.0±9.4 years old). The VFA and SFA were estimated by BCM, and the associations among the components of metabolic syndrome (waist circumference, blood pressure and related blood sample tests) were evaluated. Results VFA showed positive correlations with waist circumference, HbA1c, high-density lipoprotein (HDL)/low-density lipoprotein (LDL) cholesterol, triglyceride and uric acid level in men, while showing positive correlations with waist circumference, HDL cholesterol, triglyceride and HbA1c in women. The estimated SFA showed positive correlations with systolic blood pressure, HDL/LDL cholesterol and triglyceride in men, and HDL cholesterol and triglyceride in women. A receiver operating characteristic (ROC) analysis showed the estimated VFA to be as effective as WC to identify subject with metabolic syndrome. Conclusion By estimating the VFA using BCM, it may be possible to identify patients at risk of developing metabolic syndrome and hyperuricemia.

A Useful Tool As a Medical Checkup in a General Population—Bioelectrical Impedance Analysis

“…Where more easily accessible modality at lower cost should be developed, the bioelectrical impedance analysis (BIA) has been recently developed, which is used in population and clinical studies as a technique to estimate body composition ( 15 – 19 ). Unno and colleagues ( 15 ) found that VFA estimated by BIA is useful for detection of metabolic syndrome (MetS), as consistently reported by other studies ( 16 – 20 ).…”

Risk for metabolic diseases in normal weight individuals with visceral fat accumulation: a cross-sectional study in Japan

“…VFA estimation by the dual bioelectrical impedance analysis used in the present study can be influenced by body shape or body water distribution 39. However, the dual bioelectrical impedance analysis for measuring VFA is well correlated with that of CT,19 20 and we used categorical information of VFA. Therefore, missing VFA classifications might occur less frequently.…”

“…BMI was calculated as weight (kg) divided by height squared (m 2 ). VFA was measured in the morning before breakfast by dual bioelectrical impedance analysis which is the first device in the world for measuring visceral fat without X-ray exposure (DUALSCAN; Omron Healthcare Co., Kyoto, Japan) 19–21. BP was measured using a sphygmomanometer after 5 min of rest.…”

Reduction Effect of Calcium Alginate on Blood Triglyceride Levels Causing the Inhibition of Hepatic and Total Body Accumulation of Fat in Rats

“…Because a correlation between visceral fat mass and uric acid concentration in blood has been reported, 28,29) we measured uric acid, allantoin and blood urea nitrogen (BUN) in plasma. Allantoin and BUN showed significant dose-dependent decreases in the Ca-Alg groups.…”
