彝族、汉族居民高血压流行病学分析

Hypertension among local residents of Yi and Han nationality

目的了解四川省凉山州冕宁县彝族地区彝、汉族当地人群高血压的流行病学特征,为凉山彝族地区高血压防治干预提供科学依据。方法采用分层、整群、多阶段随机抽样方法对冕宁县10个乡镇1 388名汉族、677名彝族共计2 065名当地居民进行高血压患病率调查。结果彝族居民高血压患病率为14.62%,标化率为15.29%,血压水平收缩压(SBP)为(119.99±14.55)mm Hg,舒张压(DBP)为(74.06±8.49)mm Hg,汉族居民的患病率为14.19%,标化率15.60%,血压水平为SBP为(118.06±15.91)mm Hg,DBP(74.39±9.70)mm Hg;2个民族血压水平和高血压患病率差异均无统计学意义(P>0.05);但同一民族不同性别间差异有统计学意义(P<0.01)。随着年龄的增长,高血压患病率呈明显的增高趋势。高血压患病率还与教育程度和劳动强度密切相关。结论冕宁县彝族居民高血压患病率与汉族居民差异无统计学意义。

Objective To assess the epidemic characteristics of hypertension among local residents of Yi and Han na-tionality in Mianning county of Liangshan state,and to provide scientific basis for prevention of hypertension among Yi nationality population.Methods An investigation on hypertension prevalence with stratified cluster random sampling was carried out among 2 096 residents（1 270 Han nationality and 677 Yi nationality） in ten small towns of Mianning county.Results The prevalence rate of hypertension for local residents of Yi nationality was 14.62% with a standatdized preva-lence rate of 15.29%;the systolic blood pressure（SBP） on average was 119.99 ± 14.55 mmHg;the average diastolic blood pressure（DBP） was 74.06 ± 8.49 mmHg.The prevalence rate of hypertension in residents of Han nationality was 14.19% with a standardized prevalence rate of 15.60%;the average SBP was 118.06 ± 15.91 mmHg and the DBP was 74.39 ± 9.70 mmHg.The difference in hypertension prevalence between the two groups was not statistically significant（P 0.05）.However,the difference between the males and females in the same group was statistical significant（P 0.01）.With the age increasing,the prevalence rate of hypertension was obviously increased.The prevalence rate of hypertension was also closely related with the education level and the labor intensity.Conclusion The results indicate that the difference in hy-pertension prevalence is not statistically significant between Yi nationality and Han nationlity in Mianning county.
