2015—2018年铜陵市铜官区居民卒中流行概况分析

Analysis on prevalence of stroke in Tongguan district of Tongling city from 2015 to 2018

目的分析铜官区缺血性卒中(IS)和出血性卒中(HS)流行概况,为卒中防治提供科学依据。方法统计中国慢性非传染性疾病监测系统中,2015—2018年铜官区户籍居民因卒中发病和死亡的人数,计算IS和HS发病率、死亡率(因卒中死亡的人数占辖区总人口的比例)、病死率(因卒中死亡的人数占患病总人数的比例)和潜在减寿年数等,采用χ2检验进行统计分析。结果2015—2018年铜官区平均发病率为373.60/10万,死亡率为17.48/10万,病死率为4.68%;IS和HS发病率呈年度下降趋势,发病率、死亡率和病死率随年龄的增长呈上升趋势;IS和HS在不同季节上发病构成差异有统计学意义(P<0.01),其中IS发病高峰为春夏季,而HS发病高峰为冬春季;IS的平均减寿年数(AYLL)为9.67年,潜在减寿率(PYLLR)为0.11‰;HS的AYLL为13.25年,PYLLR为0.66‰,HS减寿程度高于IS,男性卒中减寿程度大多高于女性。结论铜官区居民卒中发病呈年度下降趋势,但随年龄的增长发病及死亡呈上升趋势,应继续强化全民健康宣教,重点是中老年人群。

Objective To analyze the prevalence of ischemic stroke(IS)and hemorrhagic stroke(HS)in Tongguan district for providing scientific basis for the prevention and treatment of stroke.Methods The number of stroke cases and deaths of registered residents in Tongguan district from2015 to 2018 reported to the Chinese chronic noncommunicable disease surveillance system was counted.The morbidity rate and death rate(proportion of the number of death caused by stroke house the total number of Tongling district)of IS and HS,fatality rate(proportion of the number of death caused by stroke house the number of patients),and the number of potential years of life loss were calculated.Chi-square test was used for statistical analysis.Results From 2015 to 2018,the average morbidity in Tongguan district was 373.60/100000,the mortality rate was 17.48/100000,and the fatality rate was 4.68%.The incidence of IS and HS showed an annually downward trend,while the morbidity,mortality and fatality rate showed an increased trend with the growth of age.The incidence composition of IS and HS in different seasons was statistically different(χ2=239.27,41.63,P<0.01).The peak of the incidence of IS was in spring and summer,and the peak of HS was in winter and spring.The average life expectancy(AYLL)of IS was 9.67 years,and the potential life expectancy(PYLLR)was 0.11‰.The AYLL of HS was 13.25 years,and the PYLLR of HS was 0.66‰.The degree of life loss of HS was higher than that of IS,and the degree of life loss of stroke in males was mostly higher than that in females.Conclusion The incidence of stroke in Tongguan district shows an annually decline trend,but the morbidity and mortality are on the rise with the growth of age,and the national health education should be strengthened,especially in the middle-aged and elderly population.
