新疆维、汉两民族50岁及以上人群高血压患病率调查

目的了解新疆地区维、汉两民族≥50岁人群高血压的现患状况,为高血压的防治工作提供依据。方法采用分层随机多级整群抽样的方式,以现场问卷调查与入户调查相结合的方法,于2004年9月至2007年6月随机抽取新疆南疆≥50岁维、汉常住居民(1年以上)进行高血压的普查。共调查8583例,其中维吾尔族4936例,汉族3647例。结果新疆地区维、汉两民族≥50岁抽样人群高血压粗患病率为50.55%(标化率49.57%),高血压患病率随着年龄的增长而上升(χ2=78.303,P<0.05);其中汉族的患病率高于维族(χ2=4.829,P<0.05);抽样人群女性高于男性(χ2=8.862,P<0.05);维族女性高于维族男性,汉族男性高于维族男性,维族男性患病率最低(均P<0.05)。单纯性收缩期高血压粗患病率为14.63%(标化率13.74%)。结论新疆维、汉两民族≥50岁人群高血压的患病率较高,女性高于男性,汉族高于维族;单纯性收缩期高血压的患病率较低。

An epidemiological investigation of hypertension in the middle-age and elderly people among the Uygur nationality and Han nationality living in Xinjiang province

Objective To investigate the prevalence of hypertension in the middle-age and elderly people among the Uygur nationality and Han nationality living in Xinjiang,the purpose is provide the basis for further control. Methods The epidemiological study adopt a multistage stratified random cluster sampling approaches to collect middie-age and elder Uygur and Hans people older than 50-year-old suffer from hypertension in totally 8583 individuals. Results The prevalence of hypertension among population over age 50 in Xinjiang was 50.55% （49.57% after standardization）, the prevalence of hypertension increased with age. The prevalence of hypertension in Uygur was 49.53% （48.62% after standardization） ,and 51.93% （50.95% after standardization） in Han nationality. The hy- pertensive ratio of Han nationality was higher than that of Uygur （ X2 = 4. 829, P 〈 0.05 ）. There was a statistically significant difference between men and women （ X2 = 8. 862, P 〈 0.05 ）, which the Uygur men had lower prevalence rate than others did. The prevalence of isolated systolic hypertension （ISH） was 14.63% （ 13.74% ）. Conclusion The results of this study showed that the higher prevalence of hypertension among Uygur and Han nationality in Xinjiang province, we should strength the prevention and treatment of hypertension among high-risk population.
