腰围/身高比预测高血压风险的可行性和价值

Feasibility and Value of Waist to Height Ratio in Predicting the Risk of Hypertension

目的:探讨和评价腰围/身高比值(WHt R)预测高血压风险的可行性和价值。方法:利用河南省高血压流行病学调查数据,分析腰围/身高比值(WHt R)、体重指数(BMI)和腰围(WC)与血压的相关关系;受试者工作特性曲线(ROC)判断最佳切点。结果:男女间WHt R及WC比较差异有统计学意义(P<0.05);WHt R与收缩压、舒张压均高度相关(r=0.398,P<0.05;r=0.426,P<0.05);3个指标中,无论男、女,ROC曲线下面积均是WHt R最大,最佳切点男、女分别为0.51、0.52,PARP%为48.48%。结论:男性WHt R>0.51,女性WHt R>0.52可有效预测高血压的患病风险。

Objective：To evaluate the feasibility and value of waist to height ratio（WHt R） in predicting the risk of hypertension.Method：Data which came from the epidemiological survey of hypertension in Henan were analyzed.The correlation between WHt R,waist cincumference（WC）,body mass index（BMI） and hypertension was analyzed.The ROC curve was used to optimal cut-off point.Result：The differences in WHt R and WC between male and female were statistically significant（P〈0.05）.WHt R showed high correlation with SBP and DBP（r=0.398,P〈0.05;r=0.426,P〈0.05）.Among the three anthropometric indices,WHt R was found to have the largest areas under the ROC curve in both gender population.The best cut-off point of WHt R was 0.51 in males and 0.52 in females.PARP% was 48.48%.Conclusion：WHt R〉0.51（male） or 0.52（female） may effectively predict the risk of hypertension.
