Abstract

Abstract: This time‐series study collects data on stroke‐related mortality, years of life lost (YLL), air pollution, and meteorological conditions in 96 Chinese cities from 2013 to 2016 and proposes a three‐stage strategy to generate the national and regional estimations of avoidable YLL, gains in life expectancy and stroke‐related population attributable fraction by postulating that the daily fine particulate matter (PM2.5 ) has been kept under certain standards. A total of 1 318 911 stroke deaths are analyzed. Each 10 µg m −3 increment in PM2.5 at lag03 is associated with a city‐mean increase of 0.31 (95% CI: 0.19, 0.44) years of life lost from stroke. A number of 914.11 (95% CI: 538.28, 1288.94) years of city‐mean life lost from stoke could be avoided by attaining the WHO's Air Quality Guidelines (AQG) (25 µg m −3 ). Moreover, by applying the AQG standard, 0.11 (0.08, 0.15) years of life lost might be prevented for each death, and about 0.91% (95% CI: 0.62%, 1.19%) of the total years of life lost from stroke might be explained by the daily excess PM2.5 exposure. This study indicates that stroke patients can have a longer life expectancy if stricter PM2.5 standards are put in place, especially ischemic stroke patients. Abstract : This study aims to examine the relationships between daily fine particulate matter PM2.5 pollution and stroke‐related years of life lost YLL and potential gains in life expectancy by achieving different PM2.5 standards in 96 Chinese cities from 2013 to 2016. The results show that daily PM2.5 exposure is associated with YLL due to stroke, and that life expectancy can be longer by adopting stricter PM2.5 standards.
