Abstract:
Objective To analyze the trend of stroke mortality among residents in Handan City of Hebei Province from 2017 to 2023, evaluate its impact on life expectancy, and provide data support for the government to formulate stroke prevention and control strategies.
Methods Stroke mortality surveillance data were collected in Handan City from 2017 to 2023. The crude mortality rate, standardized mortality rate, gender-specific mortality rate, and subtype-specific mortality rate of stroke were calculated. The average annual percentage change (AAPC) was used to analyze the trend of stroke mortality. Arriaga’s decomposition method was used to estimate the influence of stroke mortality on life expectancy across all age groups and different stroke subtypes.
Results The standardized mortality rate of stroke in Handan City fluctuated from 63.51/10
5 to 103.54/10
5 from 2017 to 2023, showing a significant decreasing trend (AAPC=-7.46%,
P<0.001). The changes of strokes mortality contributed 0.94 years to the life expectancy growth. The positive contribution from the 65 to 69 years old group was the greatest, with a contribution of 0.23 years. The declines in the mortality rates of hemorrhagic stroke, ischemic stroke and unclassified stroke contributed 19.94%, 14.61% and 0.44% to life expectancy, respectively. The positive contribution in the 65 to 69 years old group was the greatest, with a contribution of 4.90% and 3.57% for hemorrhagic stroke and ischemic stroke, respectively. The 85 ages old and above group made the greatest positive contribution to life expectancy for unclassified stroke, with a contribution rate of 0.08%.
Conclusion The standardized mortality rate of stroke in Handan City showed a declining trend from 2017 to 2023, which positively contributed to the increase of life expectancy. However, it is still suggested to strengthen the prevention and control of stroke, especially for men and people aged 60 years old and above. At the same time, attention should also be paid to the impact of different risk factors for hemorrhagic stroke and ischemic stroke on life expectancy.
