OBJECTIVE
To study the relationship between ambient air pollution and daily mortality of SARS in Beijing.
METHODS
The approach of time-series Poisson regression was used to assess the relationship between daily SARS mortality, ambient air pollution, and other factors from April 25 to May 31, 2003 in Beijing.
RESULTS
An increase of each 10 microg/m3 over a 5-day moving average of PM10, SO2 and NO2 corresponded to 1.06 (1.00-1.12), 0.74 (0.48-1.13) and 1.22 (1.01-1.48) relative risks (RRs) of daily SARS mortality, respectively. The relative risks (RRs) values depended largely on the selection of lag days.
CONCLUSION
The daily mortality of SARS might be associated with certain air pollutants in Beijing.
目的
研究北京市环境空气污染与严重急性呼吸综合征（SARS）每日死亡率之间的关系。
方法
采用时间序列泊松回归方法，评估2003年4月25日至5月31日期间北京市SARS每日死亡率、环境空气污染及其他因素之间的关系。
结果
PM10、SO2和NO2的5日移动平均浓度每增加10微克/立方米，SARS每日死亡率的相对危险度（RRs）分别为1.06（1.00 - 1.12）、0.74（0.48 - 1.13）和1.22（1.01 - 1.48）。相对危险度（RRs）值在很大程度上取决于滞后天数的选择。
结论
北京市SARS的每日死亡率可能与某些空气污染物有关。
