Skin fold thickness, hydrodensitometric weighing and body mass index (BMI) have become available for determination for the human body composition. Recently, the relevance to intra-abdominal visceral fat was reported as a risk factor for coronary artery sclerosis, insulin resistance. It was able to have many interests on the obesity and visceral fat to prevent of lifestyle-related disease. However, there is no method except for the computed tomography method (CT) for evaluating visceral fat area.New instruments using a tetrapolar multi-frequency bioelectric impedance have been developed from 5 kHz to 1 MHz could possibly distinguish between extra and intra-cellular resistance.The purpose of this study was to develop convenient and useful equations for of visceral fat area by multi-frequency bioelectric impedance, circumferences of body segment and skinfold thickness. Abdominal CT scan image was obtained at the level of umbilicus. The subjects were 82 persons (male : 51, female : 31) aged 18 to 69 years.The average BMI were 22.58 kg/m^2 for male, 21.1158 kg/m^2 for female. The average visceral fat area determined by CT were 46.2 cm^2 for male and 34.2 cm^2 for female.Multiple regression equation developed in this study for estimating visceral fat area was 2.973^*BMI + 1.151^*age + 1.006^*hip + 0.727^*wait + 0.538^*Ri of abdomen - 216.075. The correlation between visceral fat area by abdominal CT at the umbilicus level and estimating visceral fat area was 0.895 (p<0.01). These findings suggest that the equation may be useful for assessment of applicable to a visceral fat area.

皮褶厚度、水密度称重和体重指数 (BMI) 已可用于测定人体成分。最近，据报道，腹内内脏脂肪与冠状动脉硬化和胰岛素抵抗的危险因素有关。它能够对肥胖和内脏脂肪有很多兴趣，以预防与生活方式相关的疾病。然而，除了计算机断层扫描方法（CT）之外，没有其他方法可以评估内脏脂肪面积。已经开发出使用四极多频生物电阻抗的新型仪器，从5 kHz到1 MHz可以区分细胞外和细胞内电阻。本研究的目的是通过多频生物电阻抗开发方便且有用的内脏脂肪面积方程， 身体节段的周长和皮褶厚度。腹部 CT 扫描图像在脐水平获得。研究对象为82人（男性：51人，女性：31人），年龄18至69岁。男性平均BMI为22.58 kg/m^2，女性为21.1158 kg/m^2。通过CT确定的平均内脏脂肪面积男性为46.2 cm^2，女性为34.2 cm^2。本研究中开发的用于估计内脏脂肪面积的多元回归方程为2.973^*BMI + 1.151^*年龄+1.006^*臀部+0.727^*等待+腹部0.538^*Ri - 216.075。脐部腹部 CT 测得的内脏脂肪面积与估计内脏脂肪面积之间的相关性为 0.895 (p<0.01)。这些发现表明该方程可能有助于评估内脏脂肪区域的适用性。
