Objective: To assess the association between air pollution and daily stroke mortality.
Methods: All death records of the decreased who lived in one urban district of Shanghai and died from stroke from January 1 to December 31, 2001 were collected. We used a time series approach to study the acute effects of air pollution on stroke mortality after controlling for long-term trends, weather variables, and day of the week.
Results: An increase of 10 micrograms/m3 of PM10, SO2 and NO2 corresponds to 1.008 (95% CI 1.000-1.016), 1.017 (95% CI 0.998-1.036), and 1.029 (95% CI 1.001-1.057) relative risk of stroke mortality, respectively in Shanghai.
Conclusion: Our findings provide new evidence for the association between air pollution and acute stroke mortality risk.
