2018年-2022年南充市死因监测地区居民脑卒中死亡特征

Characteristics of Stroke Death Among Residents in Cause-of-Death Monitoring Areas in Nanchong City from 2018 to 2022

目的了解南充市脑卒中死亡水平、分布特点及潜在寿命、潜在工作损失情况,为脑卒中防治政策提供科学依据。方法从中国疾病预防控制中心人口死亡信息登记管理系统,选取死亡日期为2018年1月1日-2022年12月31日、户籍地址为南充市死因监测点的全部脑卒中死亡个案13080例,计算死亡率、标化死亡率、年度变化百分比、潜在减寿年数、平均潜在减寿年数、标化潜在减寿年数率、潜在工作损失年数、平均潜在工作损失年数、标化潜在工作损失年数率。结果粗死亡率和标化死亡率分别为130.56/10万和69.74/10万,5年间趋于稳定。男性粗死亡率(138.43/10万)高于女性(122.18/10万)(χ^(2)=50.63,P<0.001)。死亡率随年龄的增长而升高,趋势变化有统计学意义(χ^(2)趋势=29342.881,P<0.001)。出血性脑卒中占死亡总数的60.93%,5年来死因顺位始终位于首位。农村居民脑卒中粗死亡率和标化死亡率均高于城市居民,差异有统计学意义(χ^(2)=2933.887、1427.316,均P<0.001)。PYLL为32191.00人年,APYLL为9.71年,SPYLLR为2.94‰;WPYLL为19102.50人年,AWPYLL为9.47年,SWPYLLR为2.03‰。潜在减寿及潜在工作损失指标男性均高于女性,出血性脑卒中均高于缺血性脑卒中。结论出血性脑卒中是南充市死因监测地区脑卒中死亡的主要类型,男性、60岁以上老年人群是防治的重点人群,应采取综合性防治措施。

Objectives This study aims to understand the death level and distribution characteristics of stroke in Nanchong City,as well as potential life span and potential work loss,so as to provide scientific basis for stroke prevention and treatment policies.Methods All 13,080 stroke death cases with death dates from January 1,2018 to December 31,2022,and household registration addresses at the death cause monitoring point in Nanchong City were selected from the"Population Death Information Registration Management System"of the Chinese Center for Disease Control and Prevention.Mortality rate,standardized mortality rate,annual percent change(APC),potential years of life lost(PYLL),average potential years of life lost(APYLL),standardized potential years of life lost rate(SPYLLR),working years of potential lost rate(WYPLL),average working years of potential lost rate(AWYPLL),and standardized working years of potential lost rate(SWYPLLR)were calculated.Results The crude mortality rate and standardized mortality rate were 130.56/100,000 and 69.74/100,000 respectively,which tended to be stable in 5 years.The crude mortality rate in males(138.43/100,000)was higher than that in females(122.18/100,000)(χ^(2)=50.63,P<0.001).The mortality rate increased with age,and the trend change was statistically significant(χ^(2)_(trend)=29342.881,P<0.001).Hemorrhagic stroke accounted for 60.93%of the total deaths and had always been at the top of the list of causes of death in the past five years.The crude mortality rate and standardized mortality rate of stroke among rural residents were higher than those among urban residents,and the differences were statistically significant(χ^(2)=2933.887,1427.316,both P<0.001).PYLL was 32191.00 person-years,APYLL was 9.71 years,and SPYLLR was 2.94‰;WPYLL was 19102.50 person-years,AWPYLL was 9.47 years,and SWPYLLR was 2.03‰.The indicators of potential life expectancy reduction and potential work loss were higher in males than in females,and hemorrhagic stroke was higher than ischemic stroke.Conclusions Hemorrhagic stroke was the main type of stroke death in monitoring areas of death causes in Nanchong city.Males and elderly people over 60 years old were the key populations for prevention and control.Comprehensive prevention and control measures should be taken.
