驻浙部队团以上干部腰围身高比值与高血压危险因素的相关性

Correlation among risk factors of hypertension and waist-to-height ratio in officers of regiment and above in troops stationed in Zhejiang

目的：探讨驻浙部队团及其以上干部腰围身高比值（WHtR）与血压及高血压危险因素的相关性。方法：选择2012-2013年度来我院参加干部年度体检的团及其以上干部共2641例，分析人体质量指数（BMI）、腰围（WC）、WHtR、腰臀比（WHR）与血压的相关性；以受试者工作特征曲线（ROC曲线）分析比较上述4个指标对高血压的预测价值并判断其最佳切点。结果：（1） Pearson相关分析显示：WHtR与WC、BMI、WHR、收缩压、舒张压存在显著正相关（ r＝0.25-0.94， P＜0.005-＜0.001）；（2）上述4个指标中， ROC曲线下面积WHtR最大，为0.697（95％ CI 0.676-0.718），最佳切点为0.51；BMI为0.651（95％ CI 0.639-0.662），WC为0.689（95％ CI 0.664-0.751），WHR为0.685（95％ CI 0.672-0.698）；对于高血压的患病风险，与BMI、WC和WHR相比，WHtR的敏感性（60.68％）和特异性（70.74％）最为均衡，OR最大，为4.12（3.71-4.59）。结论：（1）驻浙部队团及其以上干部中，人体测量学指标与血压关系密切，可作为预测、评估该人群患病风险的简易指标；（2）腰围身高比值是评价驻浙部队团及其以上干部人群高血压风险最佳的人体测量学指标，预测高血压的最佳切点为0.51。

Objective：To explore the correlation among risk factors of hypertension and waist-to-height ratio （WHtR） in officers of regiment and above in troops stationed in Zhejiang .Methods ：A total of 2641 officers of regi-ment and above from troops stationed in Zhejiang ,who participated in annual physical examination in our hospital from 2012 to 2013 ,were selected .Correlation among body mass index （BMI） ,waist circumference （WC） ,WHtR , waist/hip ratio （WHR） and blood pressure were analyzed ;receiver operator characteristic curve （ROC） was used to compare and analyze the predictive value of above four indexes on hypertension and judge the optimal cut-off point . Results ：（1） Pearson correlation analysis indicated that WHtR was positively correlated with WC ,BMI ,WHR ,sys-tolic and diastolic blood pressure （r=0.25-0.94 ,P〈0.005- 〈0.001）;（2） Among above four indexes ,WHtR had the largest area under the ROC curve 0.697 （95% CI 0.676-0.718） and the optimal cut-off point was 0.51 ;and it＇s 0.651 （95% CI 0.639-0.662） for BMI ,0.689 （95% CI 0.664-0.751） for WC and 0.685 （95% CI 0.672-0.698） for WHR ;for morbidity risk of hypertension ,compared with BMI ,WC and WHR ,WHtR possessed the most balanced sensitivity （60.68% ） and specificity （70.74% ） ,and the largest OR 4.12 （3.71-4.59） .Conclusion：（1） Among officers of regiment and above in troops stationed in Zhejiang ,anthropometric indexes are closely relat-ed to blood pressure ,which can be regarded as simple indexes for predicting and assessing morbidity risk of the popu-lation ;（2） Waist-to-height ratio may be the best anthropometric index evaluating risk of hypertension in these popu-lation and its optimal cuf-off point is 0.51 for predicting hypertension .
