成都市社区脑卒中流行病学调查

Epidemiological Investigation on Cerebral Apoplexy in Community of Chengdu City

目的了解成都市社区居民脑卒中的流行病学特征,为脑卒中预防、干预提供科学依据。方法采用整群随机抽样方法抽取成都市2个社区。对132 303人采用前瞻性的热追踪,搜集社区中脑卒中发病及死亡人群。结果 2008年脑卒中发病率、死亡率分别为217.68/10万、49.13/10万,2009年发病率、死亡率分别为239.60/10万、41.57/10万,2008年-2009年标化发病率216.01/10万,标化死亡率43.61/10万。缺血性脑卒中患者构成比最高,占半数以上。发病率随年龄增长而增高(χ2=1 095.11,P<0.001),男女发病率差异无统计学意义(χ2=2.367,P=0.124)。结论成都市社区居民发病率与我国平均水平相当,死亡率略低于我国平均水平。

Objective To explore the epidemiologic features of cerebral apoplexy in community of Chengdu,and to provide references for intervention and prevention of cerebral apoplexy.Methods Two communitis in Chengdu were selected by randomized cluster sampling method.The morbidity and mortality in 132 303 people were calculated by prospective tracing.Results The annual incidence was 217.68 per 100 000,and the annual mortality was 49.13 per 100 000 in 2008.The annual incidence was 239.60 per 100 000,and the annual mortality was 41.57 per 100 000 in 2009.The age-standardized incidence was 216.01 per 100 000,and the age-standardized mortality was 43.61 per 100 000 in the two years.Ischemic cerebral apoplexy exceeded half of all and had a highest constituent ratio.The incidence Increased with the age（χ^2=1095.11,P〈0.001）,while there was no significant difference between the male and female（χ^2=2.367,P=0.124）.Conclusion The incidence of cerebral apoplexy in Chengdu City is similar to the average incidence of our country,and the mortality is lower than that of the average mortality
