辽宁阜新农村地区蒙汉两族高血压发病率及其预测因素的比较

目的比较分析阜新农村地区蒙汉两族高血压发病率及其预测因素。方法前瞻性人群随访研究。结果随访期间24.6%的汉族和34.5%的蒙族人群发展为临床高血压,但是高血压的控制率非常低(汉族1.34%,蒙族1.54%)。蒙族人群高血压年发病率为14.16/100人年[95%CI:(13.52～14.82)/100人年],汉族人群高血压年发病率为10.74/100人年[95%CI:(10.45～11.03)/100人年](P<0.05)。与汉族相比,蒙古族发展为高血压的危险比(HR)为1.131(95%CI:1.068～1.198)。女性、基线年龄、高血压前期、超重和肥胖及高血压家族史与蒙汉两族高血压发病均相关,然而饮酒只和蒙族高血压发病相关(HR:1.128;95%CI:1.045～1.219)。与有高血压家族史的汉族人群(增加12%)相比,有高血压家族史的蒙族人群发展为高血压的风险大幅提高(增加60%)。结论蒙族人群高血压发病率高于汉族人群;饮酒和高血压家族史可能是导致差异的主要原因。

Comparison of incidence rate and predictors for hypertension between rural Mongolian and Han Chinese populations in Liaoning province

Objective To explore the incident rates and determinants of hypertension among rural Chinese Han and Mongolian population in Liaoning province.Methods This is a large-scale epidemiological follow-up study.Results During follow-up,24.6% Han population and 34.5% Mongolian developed incident hypertension,with the majority of new cases were untreated and uncontrolled.Mongolian had a great risk of developing hypertension than Han population did [hazard ratio(HR): 1.131;95%CI: 1.068 to 1.198].Independent determinants for incident hypertension for both Han populations and Mongolian also included women,baseline age,baseline body mass index,family history of hypertension at baseline and baseline salt intake level.Among Han population,additional determinants included baseline alcohol drinking(HR and 95%CI:1.128,1.045 to 1.219).Conclusion We demonstrate that Chinese Han population and Mongolian in this rural low-income area of Liaoning province have a higher incidence of hypertension,which were associated with different predictors.
