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

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.

摘要

目的

评估体重指数（BMI）、腰围（WC）和腰臀比（WHR）预测腹部内脏肥胖的最佳切点、敏感性和特异性。

方法

对690名受试者（男性305名，女性385名）采用磁共振成像（MRI）测量腹部内脏脂肪面积（VA）。同时，评估BMI、WC、WHR。采用受试者工作特征（ROC）曲线进行分析。

结果

1）根据MRI诊断，超重/肥胖（OW/OB）个体中有61.7%、正常体重（NW）个体中有14.2%为腹部内脏肥胖（VA≥100 cm²）。2）VA与人体测量学变量（BMI、WC、WHR）显著正相关，其中WC相关性最佳（r = 0.73 - 0.77，P < 0.001）。3）这些人体测量学参数评估腹部内脏肥胖的最佳切点如下：BMI：26 kg/m²，WC：90 cm，WHR：0.93。其中WC的敏感性和特异性最高。4）BMI≥28 kg/m²或WC≥95 cm的受试者中，95%的男性和90%的女性出现腹部内脏肥胖。
