浙江省居民脑血管病死亡率近40年变化趋势分析

Dynamic trend of mortality of residents with cerebrovascular diseases in recent 40 years in Zhejiang

目的分析浙江省居民脑血管病死亡的流行病学特征。方法通过收集浙江省慢性病监测系统2010-2012年人群死亡监测数据与浙江省20世纪90年代和70年代2次死因回顾调查资料,分析年龄别、性别、城乡别死亡率和潜在减寿年数(YPLL)并进行比较。结果 1973-1975年、1990-1992年和2010-2012年浙江省居民脑血管病粗死亡率分别为61.49/10万、81.09/10万和114.27/10万,标化死亡率分别为118.84/10万、134.50/10万和123.05/10万,脑血管病标化死亡率随着年代推移先上升后下降。脑血管病死亡多发生在50岁之后,60岁之后死亡率明显上升,且各年龄组的死亡率依次升高;城乡比较,70年代和90年代城市脑血管病标化死亡率高于农村,2010-2012年城市脑血管病标化死亡率低于农村。近40年全人群脑血管病人均YPLL率增加了0.34%。结论当前浙江省脑血管病死亡率总体维持在一个较高水平上,但呈缓慢下降趋势,男性脑血管病死亡率高于女性,农村高于城市。

Objective To analyze the trend of mortality among residents with cerebrovascular disease（CVD）in recent 40 years in Zhejiang. Methods Death data collected from chronic disease monitoring system in Zhejiang in 2010-2012 were analyzed and compared with those collected from 2respective surveys conducted in1990’s and 1970’s in terms of factors related to mortality as age,gender,residency and YPLL. Results The crude mortality rates of residents in Zhejiang were 61.49,81.09 and 114.27 per 100,000 population in 1973-1975,1990-1992 and 2010-2012,respectively with the standardized mortality rates（SMR）of 118.84,134.50 and 123.05 per 100,000 population,which went up and then down.The mortality rate increase along with age,especially among residents aged over 60 years.The SMR among residents from urban area was higher than those from rural area in 1970’s and 1990’s,while it was lower in 2010-2012.In the last 40 years,the average YPLL%increased by 0.34%. Conclusions The mortality rate of CVD in general still remains at a high level in Zhejiang,but shows a slowly down-ward trend.The mortality rates are higher among male residents and among residents from rural area.
