摘要
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 6 90名受试者 (男 30 5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 6 1.7%、正常体重者中 14.2 %呈腹内型肥胖(VA≥ 10 0cm2 ) ;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:2 6kg/m2 ,WC :90cm ,WHR :0 .93;④BMI≥2 8kg/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。
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.
