目的探讨人群体重指数(BMI)、腰臀比(WHR)和腰身比与2型糖尿病(T2DM)的关联性。方法采用Logistic回归分析和受试者工作特征(ROC)曲线评估T2DM患者(A组,117例)和非T2DM患者(B组,130例)BMI、WHR和腰身比对T2DM发生的关联程度。结果 WHR和腰身比可能是T2DM的危险因素(P<0.05)。行逐步Logistic回归分析后,仅有腰身比和年龄纳入回归方程(P<0.05)。腰身比做为预测变量时,其对应的ROC曲线下面积最大。结论腰身比预测T2DM的效果优于BMI和WHR。
Objective To investigate the association between body mass index (BMI), waist-hip ratio (WHR) and waist-to-body ratio and type 2 diabetes mellitus (T2DM). Methods Logistic regression analysis and receiver operating characteristic (ROC) curves were used to evaluate the association between BMI, WHR and waist-to-waist ratio in T2DM patients (group A, n = 117) and non-type 2 diabetic patients (group B, n = 130). Results WHR and waist-to-waist ratio may be risk factors for T2DM (P <0.05). After the stepwise Logistic regression analysis, only the waist circumference ratio and age were included in the regression equation (P <0.05). When the waist-to-waist ratio was used as a predictor, the area under the corresponding ROC curve was the largest. Conclusion The effect of waist circumference on prediction of T2DM is better than that of BMI and WHR.
