人体测量指标对男性警察心血管病危险因素的适用性及筛检试验评价

目的：比较体质量指数（BMI）、腰围（WC）、腰臀比（WHR）、腰围身高比（WHtR）4项人体测量指标对男性公安民警心血管病（CVD）危险因素的预测和评价。方法：以4593名男性公安民警为研究对象，运用受试者特征曲线（ROC）比较4项人体测量指标对警察人群的适用性及CVD危险因素（高血压、糖尿病及血脂异常）的筛检试验评价。结果：该人群中，与WC、WHR和BMI相比，WHtR预测糖尿病、血脂异常及CVD高危人群的真实度较高，其ROC曲线下面积（AUC）较大（P分别〈0．05、〈0．01）：WHtR的灵敏度、约登指数及阴性预测值优于其他3项指标，分别为72．68％、0．35、58．9％。结论：应用WHtR在公安民警中进行筛检能够更全面地发现CVD高危人群，起到良好的预防效果。

Anthropometric indexes on predicting cardiovascular risk factors and screening test estimating in police ofricers

Objective： To compare anthropometric indexes-body mass index （BMI）, waist circumference （WC）, waist-to-hip ratio（WHR） and waist-to-height ratio（WHtR） in identifying the presence of cardiovascular disease（CVD） risk factors in police officers and estimate their validity in screening test. Methods： A study on anthropometric indexes and cardiovascular diseases risk factors （hypertension, diabetes and dyslipidemia） using Receiver Operating Characteristic Curve （ROC） method was conducted among 4 593 police officers. Results： Compared with WC, WHR and BMI, AUC of WHtR performed a better role in identifying diabetes, dyslipidemia and high risk group ofCVD （P〈0.05, P〈0.01 respectively）; The sensitivity, Youden＇s index and negative predictive value of WHtR were 71.87%, 0.35, 60.1%, respectively, which were higher than other anthropometric indexes. Conclusion： WHtR can identify high risk group of cardiovascular disease with a better prevention effect.
