Obesity, particularly visceral obesity, is associated with increased risk of cardiovascular morbidity and mortality. Therefore, cardiovascular risk should be determined by evaluating visceral fat tissue not only in obese individuals but also in non-obese individuals. We aimed to evaluate the comparison of visceral fat tissue measurement methods with computed tomography (CT).
One hundred four participants, 19 to 58 years of age (21 males, 83 females) were enrolled in this study. Participants underwent anthropometric evaluation, bioelectrical impedance analysis (BIA), ultrasonography (US), and CT examinations on the same day.
The mean body mass index (BMI) was 31.2 +/- 8.7 kg/m2 (73 individuals [70.2%] had BMI > or =30, and 31 individuals [29.8%] had BMI < 30). The non-obese group (BMI < 30) that showed the best correlation coefficient values were for visceral fat area (VFA) by BIA in all participants, males and women (r = 0.902, P < 0.001; r = 0.994, P < 0.001; r = 0.645, P = 0.01, respectively); in case of BMI > or =30 the best correlation coefficient values were for VFA by BIA (r = 0.774, P < 0.001) for all participants, and visceral fat thickness by US for males (r = 0.851, P < 0.001), and BMI (r = 0.786, P < 0.001) for females. Using multiple stepwise regression analysis, the methods best reflecting VFA by CT were as follows: In subjects with BMI < 25, BIA correlated best with CT measures of VFA; while in subjects with BMI > 30 waist-to-hip ratio showed the best correlation with CT measures of VFA. The method best reflecting VFA by CT was visceral thickness by US in males; and the method best reflecting VFA by CT in females was visceral thickness by US, BMI and waist circumference.
Anthropometric measurements and visceral fat tissue measurement methods such as US and BIA exhibit differences with respect to compliance with CT results in visceral fat tissue measurements by gender and BMI levels.
肥胖，尤其是内脏肥胖，与心血管发病率和死亡率增加有关。因此，不仅要评估肥胖个体，而且要评估非肥胖个体的内脏脂肪组织，以确定心血管风险。我们旨在评估与计算机断层扫描（CT）相比，内脏脂肪组织测量方法的比较。
本研究共纳入 104 名年龄在 19 至 58 岁（21 名男性，83 名女性）的参与者。参与者在同一天接受了人体测量评估、生物电阻抗分析（BIA）、超声检查（US）和 CT 检查。
平均体重指数（BMI）为 31.2 +/- 8.7 kg/m2（73 名[70.2%]参与者 BMI≥30，31 名[29.8%]参与者 BMI < 30）。在所有参与者、男性和女性中，非肥胖组（BMI < 30）中 BIA 测量的内脏脂肪面积（VFA）显示出最佳相关系数值（r = 0.902，P < 0.001；r = 0.994，P < 0.001；r = 0.645，P = 0.01）；在 BMI≥30 的情况下，BIA 测量的 VFA 最佳相关系数值（r = 0.774，P < 0.001）用于所有参与者，男性 US 测量的内脏脂肪厚度（r = 0.851，P < 0.001）和女性 BMI（r = 0.786，P < 0.001）。使用多元逐步回归分析，与 CT 测量的 VFA 相关性最佳的方法如下：在 BMI<25 的受试者中，BIA 与 CT 测量的 VFA 相关性最佳；而在 BMI>30 的受试者中，腰围臀围比与 CT 测量的 VFA 相关性最佳。US 测量的内脏厚度是男性 CT 测量 VFA 的最佳方法；而女性 CT 测量 VFA 的最佳方法是 US、BMI 和腰围。
根据性别和 BMI 水平，与 CT 结果相比，人体测量和 US 等内脏脂肪组织测量方法在符合内脏脂肪组织测量方面存在差异。
