中老年人群脑卒中流行现状及其影响因素研究

Study of Prevalence of Stroke and its Influencing Factors in the Middle-aged and Elderly Population

目的:了解我国中老年人群脑卒中流行现状及其危险因素。方法:利用CHARLS数据,采用χ2检验,Logistic回归进行分析。结果:共18763例有效观察对象,其中951例患有脑卒中,脑卒中的患病率为5.07%,男、女患病率分别为5.55%、5.15%。从流行病学分布特征观察,中老年人群在不同年龄、地区、户籍、婚姻情况、受教育程度分布以及不同疾病史高血压、血脂异常、糖尿病、心脏疾病、抑郁症的脑卒中患病率差异有统计学意义(P<0.05),而不同民族分布的脑卒中患病率差异无统计学意义(P>0.05)。Logistic回归分析结果显示,与脑卒中相关的危险因素主要有:年龄、地区、高血压、糖尿病、血脂异常、心脏疾病和抑郁症。结论:我国中老年人群脑卒中的防治应根据流行现状和危险因素针对性地实施干预措施。

Objective:Analysis of the epidemic status and related factors of stroke among middle-aged and elderly people in China.Methods:In this study,Chi-square test and Logistic regression analysis were used to analyze the CHARLS survey data.Results:Of the 18,763 participants in the study,951 had stroke.The prevalence of stroke was 5.07%,5.55%in males and 5.15%in females,respectively.According to the epidemiological distribution characteristics,there were significant differences in the prevalence of stroke among middle-aged and elderly people in different age,region,household registration,marital status,education level and hypertension,dyslipidemia,diabetes,heart disease and depression(P<0.05),while there was no significant difference in the prevalence of stroke among different ethnic groups(P>0.05).Logistic regression showed that the main risk factors associated with stroke were age,region,hypertension,diabetes,dyslipidemia,heart disease and depression.Conclusions:The prevention and treatment of stroke in middleaged and elderly people in China should carry out targeted intervention measures according to the epidemic status and risk factors.
