糖尿病与肥胖、脂代谢异常

　　【摘要】目的 评价中青年腹型肥胖的简易体脂参数及临床应用价值。方法 应用MRI 对267 名受试者行腹内脂肪面积(AVF area)测量，同时测量BMI、WC及WHR,并与MR测量的AVF area进行比较，以受试者工作特征曲线(ROC)评价简易体脂参数对腹型肥胖的诊断价值。结果 BMI、WC、WHR与AVF area呈正相关(r分别为0.645,0.782,0.618)，受试者工作特征(ROC)曲线下面积男性以WC最高，女性以BMI最高。简易体脂参数评价腹型肥胖最佳参数的最佳切割点为男性WC 88 cm ，女性BMI 24 kg / m 2 。结论 BMI 、WC及WHR均可估测腹型肥胖，男性WC、女性BMI可靠性最好。

　　【Abstract】 To evaluate anthropometric parameters of abdormal visceral obesity in young and Middle-aged people and the clinical value . Methods Abdominal visceral fat(AVF)areas in 267 subjects were measured with MRI and compared with those determined by MR . Meanwhile，BMI,WC,WHR were assessed. ROC curve was used as index for analysis Results (1)AVF area was significantly positively correlated with BMI,WC and WHR(r=0.645, 0.782, 0.618), besides, WC(0.89)in male and BMI (0.85) in female have the largest area under ROC curve . (2) The best cut-off points of these anthropometric parameters in assessing abdominal visceral obesity were as following: WC 88 cm in male, BMI 24 kg / m 2 in female. Conclusion BMI, WC, WHR all can predict abdominal visceral obesity with WC as the best in male and BMI as the best in female.
