【摘要】 目的　分析大气污染急性暴露对居民每日脑卒中死亡的影响。方法　采用时间序列的半参数广义相加模型 ,在控制死亡的长期趋势、气象因素、“星期几效应”等混杂因素的基础上 ,分析了上海市某区 2 0 0 1年 1月 1日～ 12月 31日大气污染与居民每日脑卒中死亡的关系。结果　大气PM10 ,SO2 和NO2 4 8h平均浓度每增加 10 μg m3 ,居民因脑卒中而死亡的相对危险度分别为 1 0 0 8(95 %CI 1 0 0 0～ 1 0 16 ) ,1 0 17(95 %CI 0 998～ 1 0 36 )和 1 0 2 9(95 %CI1 0 0 1～ 1 0 5 7)。结论　上海市某区目前的PM10 和NO2 水平对居民脑卒中死亡有影响。更多还原

【Abstract】 Objective To assess the association between air pollution and daily stroke mortality. Methods All death records of the deceased 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 10μg/m3 of PM 10, SO 2 and NO 2 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.更多还原
