目的研究中国成人腰围身高比(WHtR)与血脂异常的关系,并提出WHtR预测血脂异常的适宜截点.方法采用整群随机抽样,对2008至2009年度在4个全国性体检机构进行健康查体的221 270名城市人群,测量其身高、体重、腰围(WC),计算体质指数(BMI)和WHtR,并检测血脂四项.采用受试者工作特征曲线(ROC)比较曲线下面积,计算不同水平肥胖指标预测血脂异常的灵敏度和特异度,通过约登指数最大值找到适宜截点.结果 WHtR在高TC血症、高TG血症及高LDL-C血症的ROC曲线下面积最大,其次为WC及BMI；WHtR最佳截点范围男性为0.49 ～0.50,女性为0.47 ～0.49；WC男性为83～ 85 cm,女性为73～76 cm;BMI男性为24 ～ 25 kg/m2,女性为22～23 kg/m2.结论 WHtR筛查不同类型的血脂异常优于WC和BMI,推荐适宜截点男女性均为0.5.

Objective To explore the association between waist-to-height ratio (WHtR) and dyslipidemia in Chinese adults and to find out an optimal threshold of WHtR for predicting dyslipidemia.Methods A total of 221 270 adults from 4 health checkup centers nationwide were selected by using cluster random sampling method.Height,body weight,waist circumference (WC),total cholesterol (TC),triglyceride (TG),high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol(LDL-C) were measured.Body mass index (BMI) and WHtR were then calculated.The area under the receiver operating characteristic curve(AUC) was analyzed and optimal cutoffs were estimated by maximizing the sums of sensitivity and specificity.Results WHtR showed the largest AUCs in the participants with higher TC,TG and LDL-C,followed by increased WC and BMI.In male and female,the optimal thresholds of WHtR,WC and BMI for predicting dyslipidemia were 0.49-0.50 and 0.47-0.49,83-85and 73-76 cm,and 24-25 and 22-23 kg/m2,respectively.Conclusion WHtR may be superior to WC and BMI for predicting dyslipidemia,and an unisex cutoff of 0.5 should be recommended.
