Characteristics of Stroke Death Among Residents in Cause-of-Death Monitoring Areas in Nanchong City from 2018 to 2022
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)(x2=50.63,P＜0.001).The mortality rate increased with age,and the trend change was statistically significant(x2 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(x2=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.
