AI Article Synopsis

  • Recent decades have seen China implementing policies aimed at reducing air pollution, specifically targeting health issues related to stroke caused by fine particulate matter (PM).
  • Analysis of data from the Global Burden of Disease study indicates that the rate of disability-adjusted life years (DALY) lost due to stroke from PM increased dramatically from 1990 to 2012, but showed a steady decrease from 2012 to 2019.
  • The research highlights that while rates for ischemic and intracerebral hemorrhage strokes initially rose, they have since declined, demonstrating a positive impact of air quality improvement efforts on public health in China.

Article Abstract

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 (PM ).

Methods: 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 PM in China, increased dramatically during 1990-2012, subsequently decreased at an annual percentage change (APC) of -1.98 [95% confidence interval ( ): -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% : -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% : -2.74, -0.16) during 2003-2007 and -3.33 (95% : -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 PM attributable stroke burden in China during 1990-2019, highlighting the health effects of air quality improvement policies.
