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 understand the epidemiological characteristics of hypertension among local populations of Yi nationality and Han nationality in Mianning County, Liangshan Prefecture, Sichuan Province, and to provide a scientific basis for the prevention and treatment of hypertension in Liangshan Yi ethnic region. Methods A stratified, cluster-based and multistage random sampling method was used to survey the prevalence of hypertension among 1 388 Han and 677 Yi nationality residents from 10 townships in Mianning County. Results The prevalence rate of hypertension in Yi residents was 14.62%, the standardization rate was 15.29%, the systolic blood pressure (SBP) was (119.99 ± 14.55) mm Hg and the diastolic blood pressure (DBP) was (74.06 ± 8.49) mm Hg The prevalence rate of residents was 14.19%, standardized rate was 15.60%, SBP was (118.06 ± 15.91) mm Hg, and DBP (74.39 ± 9.70) mm Hg. The prevalences of blood pressure and hypertension among the two ethnic groups were There was no significant difference (P> 0.05), but there was significant difference between different genders in the same ethnic group (P <0.01). With age, the prevalence of hypertension was significantly increased. The prevalence of hypertension is also closely related to the level of education and labor intensity. Conclusions The prevalence of hypertension in Mianning Yi residents is not statistically different from that in Han residents.
