[A time-series study on the association of stroke mortality and air pollution in Zhabei District, Shanghai].
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.


CONCLUSIONS
Our findings provide new evidence for the association between air pollution and acute stroke mortality risk.
