Epidemiological characteristics of stroke mortality in Yuyao,Zhejiang Province,2015-2022
摘要
Abstract
[Objective]To analyze stroke mortality data from Yuyao,Zhejiang Province,from 2015 to 2022,and to provide references for the development of effective stroke prevention and control strategies in Yuyao and similar county-level cities or districts.[Methods]Data on all stroke-related deaths in Yuyao from 2015 to 2022 were collected.Metrics including crude mortality rate(CMR),Chinese-standardized mortality rate,world-standardized mortality rate,truncated mortality rate(35-64 years),cumulative mortality rate(0-74 years),premature mortality rate,potential years of life lost(PYLL),average years of life lost(AYLL),PYLL rate(PYLLR),and average annual percentage change(AAPC)were calculated.Differences between groups were compared using the Chi-square test.Linear regression was utilized to calculate AAPC and analyze mortality trends.[Results]From 2015 to 2022,a total of 6 533 stroke deaths were recorded among residents in Yuyao,with ischemic stroke accounting for 70.60%and hemorrhagic stroke accounting for 29.40%.The average CMR was 97.67/100 000,China-standardized mortality rate was 45.82/100 000,and world-standardized mortality rate was 32.10/100 000.No statistically significant differences were observed in CMR,China-standardized morality rate,or world-standardized mortality rate over the 8 years(all P>0.05).Stroke deaths primarily occurred in winter(from December to February of next year),accounting for 31.21%of the cases.Male stroke mortality rate(108.15/100 000)was significantly higher than female mortality rate(87.49/100 000,χ2=73.195,P<0.001).Stroke mortality rate increased significantly with age(χ2trend=17 839.150,P<0.001),peaking at 1 867.82/100 000 in the≥85-year-old age group.Hemorrhagic stroke mortality rate was higher than ischemic stroke mortality rate in the 10-64-year-old age group,whereas ischemic stroke mortality rate exceeded hemorrhagic stroke mortality rate in those aged 65 years and above.The PYLL caused by stroke mortality was 11 014.00 person-years,with an AYLL of 10.98 years,and a PYLLR of 1.87‰.[Conclusion]Stroke mortality in Yuyao has remained relatively stable.A community-based comprehensive chronic disease intervention mechanism should be established,with a focus on males and the elderly.This mechanism should integrate community health education,stroke risk assessment,screening and intervention,two-way patient referral systems,and tiered rehabilitation services to reduce mortality rate and mitigate life expectancy loss.关键词
