[目的]评价体重指数(BMI)、腰围(WC)、腰臀比(WHR)估测男性2型糖尿病患者腹内型肥胖的最佳临界点、敏感度及特异度。[方法]应用CT对91例男性2型糖尿病患者在腰椎4-5间隙水平进行腹腔内脏器脂肪含量(VA)的测量,同时测量其体重(BW)、身高(H)、腰围(WC)、臀围(HC)、并计算体重指数(BMI)和腰臀比(WHR)。以受试者工作特性(ROC)曲线评价简易体脂参数对男性2型糖尿病患者腹内型肥胖的诊断价值。[结果]①经CT诊断,超重及肥胖者中89.80%、正常体重者中47.62%呈腹内型肥胖(VA≥100crn2);②BMI、WC、WHR与腹内脂肪面积呈正相关关系,尤以BMI、WC的相关性为好;③简易体脂参数估测男性2型糖尿病患者腹内脂肪积聚的最佳切割点为BMI:25kg/m2,WC:90cm,WHR:0.93;④当BMI≥28kg/m2,100%的患者为腹内型肥胖,当WC≥95cm时,91.90%的患者为腹内型肥胖。[结论]BMI、WC及WHR都可估测男性2型糖尿病患者腹内型肥胖,但以BMI、WC的准确率为高。
[Objective] To evaluate the best cut-off point, sensitivity and specificity of BMI, WC and WHR in estimating intra-abdominal obesity in male type 2 diabetic patients. [Method] The abdominal visceral fat content (VA) was measured in 91 male patients with type 2 diabetes mellitus at the clearance level of 4-5 at the lumbar spine. The body weight (BW), height (H), waist circumference Hip (HC), and body mass index (BMI) and waist-hip ratio (WHR) were calculated. To evaluate the diagnostic value of simple body fat parameters in patients with type 2 diabetes mellitus with intra-abdominal obesity based on ROC curves. [Results] ①There were 89.80% of the overweight and obese, 47.62% of the normal weight were diagnosed as abdominal obesity (VA≥100crn2) by CT; ②BMI, WC and WHR were positively correlated with the intra-abdominal fat area, especially the BMI , WC is good; ③Easy body fat parameter estimation of abdominal fat accumulation in male patients with type 2 diabetes the best cutting point is BMI: 25kg / m2, WC: 90cm, WHR: 0.93; ④ When BMI≥28kg / m2, 100% of patients were intra-abdominal obesity, while WC≥95cm, 91.90% of patients were intra-abdominal obesity. [Conclusion] The BMI, WC and WHR all can estimate the intra-abdominal obesity in male patients with type 2 diabetes, but the accuracy of BMI and WC is high.
