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.
目的
评估空气污染与每日中风死亡率之间的关联。
方法
收集了2001年1月1日至12月31日期间居住在上海某市区并死于中风的所有死亡记录。在控制长期趋势、天气变量和星期几之后，我们采用时间序列方法研究空气污染对中风死亡率的急性影响。
结果
在上海，PM10、SO2和NO2每增加10微克/立方米，中风死亡率的相对风险分别为1.008（95%可信区间1.000 - 1.016）、1.017（95%可信区间0.998 - 1.036）和1.029（95%可信区间1.001 - 1.057）。
结论
我们的研究结果为空气污染与急性中风死亡风险之间的关联提供了新的证据。
