Trial Evaluation of Visceral Fat Characteristics by Abdominal Bioelectrical Impedance Method

Aim: As the abdominal bioelectrical impedance method is changed by visceral fat area by CT (VFA) and quantity, we examined whether the abdominal bioelectrical impedance per measured area (V/A) as the visceral fat characteristics index is useful for diabetes care. Methods: The subjects were 33 Japanese obese female outpatients. We investigated the correlations of V/A measured by the abdominal bioelectrical impedance method device and of VFA, for each measurement item. And we analyzed the related factors for HOMA-R as the insulin resistance index and for V/A as visceral fat characteristics index by stepwise multiple regression analysis. Results: As there is no correlation between the V/A we used and VFA, we report that the visceral fat characteristics (density) from V/A is not directly associated with VFA (area). We investigated correlations of V/A and VFA for the measured items. There were significant correlations of V/A for peakVO(2)/W, BS, IRI, HOMA-R, lean body. There were significant correlations of VFA for peakVO(2)/W, IRI and HOMA-R, BMI, waist circumference, and body weight. We analyzed the related factors for HOMA-R and for V/A by stepwise multiple regression analysis. From the results of stepwise multiple regression analysis, the final independent variables V/A and VFA were chosen for HOMA-R, and peakVO(2)/W was chosen for V/A. Conclusion: We report that the visceral fat characteristics (density) from V/A are not directly associated with VFA (area). Hence the evaluation of visceral fat characteristics by V/A is important for diabetes care and treatment of obesity.
