Abstract 11493: A New Measurement System of Visceral Fat Area by Bioelectrical Impedance Analysis in a Population of community-Dwelling

Abstract

Accumulation of visceral fat leads to metabolic syndrome and increases risks of cerebro-cardiovascular diseases. Accurate measurement of visceral fat area (VFA) is commonly performed by the abdominal cross- sectional image measured by X-ray computed tomography (CT). However, this method is expensive and associated with radiation. In this regard, cheaper and more easily accessible modality is desirable. Recently, bioelectrical impedance analysis (OMRON, HDS-2000 DUALSCAN^R) was developed. Therefore, we investigated the clinical usefulness of DUALSCAN^R in 226 subjects who received a health examination. They received blood chemistries, electrocardiography, cardio and carotid ultrasonography, and underwent VFA measurement by DUALSCAN^R. Average of VFA was 83.5±36.3 cm² in men, and 64.8±28.0 cm² in women. VFA was correlated to weight (r=0.7404, p<0.0001), body mass index (BMI) (r=0.7320, p<0.0001), and waist circumstance (r=0.7393, p<0.0001). In multivariate analyses, VFA was significantly associated with weight (p<0.0001), BMI (p<0.0001), waist circumstance (p<0.0001), high sensitive-CRP (p<0.05), PAI-1(p<0.0001), HDL-cholesterol (inversely, p=0.004), triglycerides (p<0.0001), uric acid (p=0.0021), HbA1c (p=0.0005), and IMT (p=0.0208). We, for the first time, evaluated VFA by this new method in a large number of subjects. VFA was significantly associated with waist, BMI, and inflammatory markers. Our results may suggest that DUALSCAN^R is useful to measure VFA simply and cheaply in a large number of subjects.
