内蒙古农村高血压与脑卒中患病率调查分析

prevalence and relationship between hypertension and stroke in rural village of Inner Mongolia

目的了解内蒙古农村≥35岁人群高血压与脑卒中患病率的情况及两者的关系。方法采用整群随机抽样方法,抽取内蒙古准格尔旗常住居民进行统一体格检查、问卷调查和实验室检查,收集资料并进行统计学分析。结果 （1）本次流行病学调查有关该项研究的入选人数为72 350人,应答率为88.7%,其中血压正常人群52 085人,高血压病20 265人,高血压患病率为28.01%;其中非卒中69 762人,卒中2 588人,卒中患病率为3.58%。（2）高血压、脑卒中患病率均随着年龄的增加而逐步升高（P〈0.01）,经多因素分析调整后,高血压对脑卒中的OR为2.386（2.211-2.576）,对脑梗死OR值为2.327（2.130-2.541）,对脑出血OR值2.437（2.405-2.469）。（3）脑梗死、脑出血患病率均有随年龄增长而上升。结论内蒙古准格尔旗为高血压、脑卒中高发区,应采取全面的高血压防治措施,以减少脑卒中的患病率。

Objective To study the correlation between hypertension and stroke of≥35 year olds in Jungar Banner, Inner Mongolia. Methods Use cluster random sampling method to extract Jungar Banner, Inner Mongolia ordinarily resident in a unified physical examination, questionnaires and laboratory tests, collect data and statistical analysis. Results 1 Number selected for the study of the epidemiological survey of 72 350 people, response rate of 88.7%, 52 085 of whom have normal blood pressure and 20 265 of whom suffer from hypertension. Hypertension prevalence was 28.01%. 69 762 of the people have no stroke and 2 588 of whom suffer from stroke. Stroke prevalence was 3.58%. 2 The prevalence of hypertension and stroke increased with advanced age（P 〈0.01）. By multivariate Logistic regression, the odds ratio（OR） of hypertension for stroke, cerebral infarction and cerebral hemorrhage were 2.386（2.211-2.576）, 2.327（2.130-2.541） and 2.437（2.405-2.469）, respectively. 3 Cerebral infarction and cerebral hemorrhage prevalence rates increased with age.
