Abstract:

目的评价体重指数(BMI)、腰围(WC)、腰臀比(WHR)估测腹内型肥胖的最佳临界点及敏感度、特异度。方法应用核磁共振(MRI)对690名受试者(男305人,女385人)进行腹内脂肪(VA)测量,同时测量BMI、WC、WHR。以受试者工作特性(ROC)曲线评价简易体脂参数对腹内型肥胖的诊断价值。结果①经MRI诊断,超重/肥胖者中61.7%、正常体重者中14.2%呈腹内型肥胖(VA≥100cm2);②BMI、WC、WHR与腹内脂肪面积呈显著正相关,尤以WC的相关性最好;③简易体脂参数估测腹内脂肪积聚的最佳切割点为BMI:26kg/m2,WC:90cm,WHR:0.93;④BMI≥28kg/m2、WC≥95cm时,95%的男性及90%左右的女性呈腹内型肥胖。结论BMI、WC及WHR都可估测腹内型肥胖,但以腰围的准确率稍高。

English Abstract:

Objective To evaluate the best cut-off point, sensitivity and specificity of body mass index (BMI), waist circumference(WC) and Waist-to-hip ratio (WHR) in predicting of abdominal visceral obesity. Methods Abdominal visceral fat area (VA) was measured with magnetic resonance image (MRI) in 690 subjects (men: 305, women: 385). Meanwhile, BMI, WC, WHR were assessed. Receiver operating characteristic (ROC) curve was used as index for analysis. Results 1) 61.7% of over-weight/obesity (OW/OB) and 14.2% of normal weight (NW) individuals were abdominal visceral obesity ( VA≥100 cm 2) by MRI diagnosis. 2) VA was significantly positively correlated with anthropometric variables (BMI, WC, WHR), in which WC was the best (r= 0.73- 0.77, P 0.001). 3) The best cut-off points of these anthropometric parameters in assessing abdominal visceral obesity were as follow: BMI:26 kg/m 2, WC:90 cm, WHR: 0.93. Among them WC showed most sensitive and specific. 4) 95% men and 90% women appeared abdominal visceral obesity in subjects with BMI≥28 kg/m 2 or WC≥95 cm.Conclusion BMI, WC, WHR can all predict abdominal visceral obesity, with WC the best.
