1999—2006年天津市居民脑卒中死亡趋势与分布

The Epidemiological Trend and Distribution of Stroke Mortality in Tianjin Residents during 1999 to 2006

目的分析1999—2006年天津市居民脑卒中死亡的趋势与分布,为预防和控制脑卒中提供依据。方法以1999—2006年天津市脑卒中死亡报告102718例为基础数据,应用ICD-9或ICD-10进行脑卒中分型,描述脑卒中死亡的年龄、性别及地区分布,分析不同类型脑卒中死亡构成的变化,按照2000年世界人口对脑卒中死亡率进行标化,应用χ2检验进行死亡率、构成比的比较。结果天津市脑卒中死亡率呈下降趋势,由133.52/10万降至102.52/10万。1999—2006年各年份男性脑卒中死亡率(120.17/10万～157.74/10万)均高于女性(84.87/10万～109.31/10万),脑卒中死亡率随年龄增加而上升(P<0.05)。近5a来脑梗死是城市居民脑卒中死亡的主要原因,其构成比超过了50%。农村居民脑卒中死亡以脑内出血型为主(各年度均占50%以上)。结论脑卒中死亡的性别和地区分布存在差异,脑卒中死亡类型的构成和分布出现显著变化,应制定有针对性的预防措施,以减少脑卒中的死亡。

Objective To analyze the epidemiological trend and distribution of stroke mortality in residents of Tianjin, China. Methods The study was based on 102 718 died eases with stroke in Tianjin between 1999 and 2006. The death cause and the stroke typing were coded according to the ICD-9 and ICD-10. Standardized mortality rates were calculated for stroke and its subtypes, adjusted for age and sex according to the world standard population of the Year 2000. The age, sex and geographic distribution of the stroke and its subtype mortality were analyzed. Chi-square tests were used to determine the statistical significance of mortality trends and differences. Results Stroke mortality rate in Tianjin declined from 133.52/100 000/year in 1999 to 102.52/100 000/year in 2006. Cerebral infarction accounted for more than 50% of stroke mortality. The stroke mortality rate for males （120.17/100 000 to 157.74/100 000） was higher than that for females （84.87/100 000 to 109.31/100 000）. Stroke mortality rates elevated with age （P〈0.05）. The main death cause of stroke in the suburban areas was attributed to cerebral hemorrhage. Conclusion There are significant differences in the distribution of stroke mortality by subtype, age, sex, and geographic areas. Various subtypes of stroke are associated with different risk factors and therefore it requires different prevention and control measures.
