Obesity management is a critical global issue. It is essential to evaluate visceral adiposity which is associated with metabolic syndrome and cardiovascular disease. This study aims at precisely evaluating the necessity of visceral adipose tissue in obesity management. We assessed the validity of visceral fat area (VFA) measurement using bioelectrical impedance analysis (BIA) with computed tomography (CT) as a reference in obese subjects. Although VFABIA exhibited significant correlation with VFACT, the difference between VFACT and VFABIA increased with an advancing degree of obesity. The BIA device seemingly underestimated VFA in obese subjects compared with normal-weight subjects.
