长沙社区人群脑卒中患者发病的监测研究

Surveillance of incidence of cerebral hemorrhage in community populations in Changsha

目的 了解长沙市社区人群脑卒中发病情况。方法 1986-1990年在长沙市社区随机选取的 10 000名人群中进行脑卒中发病监测,并进行其亚型分析。发现长沙市脑出血年发病率为171.7/10万,又从1991年起扩大监测人群至50 000人,监测时限直到2000年12月。结果 1986-2000年12月,长沙市社区人群脑出血年平均发病率为128.5/10万(调整率为100.3/10万),脑卒中年平均发病率为238.9/10万(调整率为200.2/10万),脑出血占脑卒中的比例为53.8％。结论 长沙市社区人群脑出血连续15年中年平均发病率达128.5/10万,为世界脑出血的高发区。

Objective To observe the incidence of cerebral apoplexy among the community populations in Changsha, Hunan Province. Methods Surveillance of the incidence of cerebral apoplexy and analysis of its subtypes were conducted among 10 000 urban residents in Changsha selected by random cluster sampling from 1986 to 1990. The number of people under surveillance was amplified to 50 000 in 1991 and the studies lasted to December 2000. Results Among the Chamgsha populations, the annual average incidence of cerebral hemorrhage was 171.7 per 100 000 during the period 1986 - 1990. The annual average incidence of cerebral apoplexy was 238.9/100 000 with an adjusted rate of 200.2/100 000, and the annual average incidence of cerebral hemorrhage, accounting for 53.8% of cerebral apoplexy, was 128.5/100 000 with an adjusted rate of 100.3/100 000) . Conclusion The annual average incidence of cerebral hemorrhage in community populations is 128.5 per 100 000 during the period of fifteen years, 1986 - 2000, in Changsha, one of the areas with high incidence of cerebral hemorrhage.
