摘要
目的探讨体质指数(BMI)、腰围(WC)、腰臀比(WHR)、腰围身高比(WHtR)4种肥胖指标对预测糖尿病风险的效果。方法利用四川成都市2008年调查5 205名40～70岁人群数据,分析4种指标及身高的相关关系;应用受试者特性曲线(ROC)、Logistic回归分析比较4个指标对糖尿病的预测效果。结果 WHtR与腰围相关性最高(男性r=0.938 4,女性r=0.956 2,P<0.05);4个指标中,ROC曲线下面积男性WHR最大,女性WHtR最大(男性c=0.641 5,女性c=0.669 2);Logistic回归分析中,男性WHR,女性WC预测价值最佳(男性OR=3.107,女性OR=2.684),调整4个指标交互作用后,BMI结合WC、WHR、WHtR并不能明显提高模型预测效果。结论本研究人群糖尿病风险模型中,男性选择WHR作为肥胖评定指标,最佳切点为0.90,女性选择WC作为肥胖评定指标,最佳切点为83 cm,但在不同地区和人群的应用需要进一步研究。
Objective To evaluate the predictive values of body mass index（BMI）,waist circumference（WC）,waist/hip ratio（WHR）,and waist-height ratio（WHtR） to diabetes risk.Methods Data came form the 2008 Chengdu Diabetes Survey,a population based cross-sectional study,and 5 205 residents aged 40-70 years were enrolled.Results WHtR showed positive correlation with WC（r=0.938 4 in male,r=0.952 6 in female,P〈0.05）.WHR in male and WC in female showed low correlation with height（r=0.027 8 in male,r=0.029 4 in female,P〉0.05）.WHR in male and WHtR in female were found to have the largest areas under the ROC curve relative to diabetes（c=0.641 5 in male,c=0.669 2 in female）.Logistic regression analysis showed that WHR in male and WC in female were the best predictors related to obesity among the 4 deliberated indexes to diabetes risk（odds ratio=3.107 in male,OR=2.684 in female）.After controling the interaction of 4 indexes,BMI combined with WC,WHR or WHtR could not improve the predictive value in the model.Conclusion The results suggest that WHR in male and WC in female are the best predictors related to obesity among the 4 evaluation indicators.The best cut-off points of WHR in male and WC in female are 0.90 and 83 centimeter,respectively,and the application of the predictors in defferent area or population needs to be researched.
