呼吸系统流行病混淆了空气污染和日常死亡之间的联系吗?摩根富林明-欧洲呼吸杂志》乔和J SP - 723 LP - 728欧元六世- 16 - 4盟-布拉加,AL非盟- Zanobetti AU -施瓦兹,J Y1 - 2000/10/01 UR - //www.qdcxjkg.com/content/16/4/723.abstract N2 -每日死亡与空气污染有关。这种联系可能是由不受控制的风险因素造成的。为了估计呼吸系统流行病造成的空气污染与健康影响之间的潜在混淆,对空气污染和每日死亡进行了一项时间序列研究。每天的死亡记录来自五个美国城市:芝加哥,伊利诺斯州;底特律,心肌梗死;明尼阿波利斯、锰;宾夕法尼亚州匹兹堡;和西雅图,佤邦。研究获得了空气动力直径50%为10微米(PM10)的颗粒物的每日水平和天气测量数据。 City-specific analysis was carried out using Poisson regression, adjusting for time trend, ambient temperature, dew point, barometric pressure and day of the week. A cubic polynomial was used for each epidemic period (> or =10 days of excessive pneumonia hospital admissions), and a dummy variable was used to control for isolated epidemic days. A 10-microg x m(-3) increase in PM10 concentration (lag 0-1) was associated with increased daily deaths in Chicago (0.81%, 95% confidence internal (CI) 0.54-1.09); Detroit (0.87%, 95% CI 0.60-1.15), Minneapolis (1.34%, 95% CI 0.78-1.90), Pittsburgh (0.84%, 95% CI 0.51-1.18) and Seattle (0.52%, 95% CI 0.11-0.94). When controlling for respiratory epidemics, small decreases in the PMlo effect were observed (Chicago 9%, Detroit 11%, Minneapolis 3%, Pittsburgh 5%, and Seattle 15%). The overall effect of PM10 concentration was 0.85% (95% CI 0.60-1.10) per 10 microg x m(-3) before controlling for epidemics and 0.78% (95% CI 0.51-1.05) after. This study showed that the association between air pollution and daily deaths is not due to failure to control for influenza or pneumonia epidemics. ER -
