Description
Summary:Objective In recent decades, China has implemented a series of policies to address air pollution. We aimed to assess the health effects of these policies on stroke burden attributable to ambient fine particulate matter (PM2.5). MethodsJoinpoint regression was applied to explore the temporal tendency of stroke burden based on data from the Global Burden of Disease 2019 study. Results The age-standardized rates of disability-adjusted life year (DALY) for stroke attributable to ambient PM2.5 in China, increased dramatically during 1990–2012, subsequently decreased at an annual percentage change (APC) of –1.98 [95% confidence interval (CI): –2.26, –1.71] during 2012–2019. For ischemic stroke (IS), the age-standardized DALY rates doubled from 1990 to 2014, and decreased at an APC of –0.83 (95% CI: –1.33, –0.33) during 2014–2019. Intracerebral hemorrhage (ICH) showed a substantial increase in age-standardized DALY rates from 1990 to 2003, followed by declining trends, with APCs of –1.46 (95% CI: –2.74, –0.16) during 2003–2007 and –3.33 (95% CI: –3.61, –3.06) during 2011–2019, respectively. Conversely, the age-standardized DALY rates for subarachnoid hemorrhage (SAH) generally declined during 1990–2019. Conclusion Our results clarified the dynamic changes of the ambient PM2.5–attributable stroke burden in China during 1990–2019, highlighting the health effects of air quality improvement policies.
