为了实现成功举办2008年奥运会和残奥会的承诺，中国政府采取了前所未有的措施来改善北京的空气质量。我们报告了2008年夏季奥运会期间北京成人哮喘患者的空气质量和门诊就诊情况。研究人员确定了三个研究时期：夏季基准期（6月1日至6月30日，没有任何空气污染控制措施），奥运会前（7月1日至8月7日，交通限制生效），以及奥运会（8月8日至9月20日，进一步限制工业排放）。每日哮喘门诊就诊数据来自北京朝阳医院哮喘登记。我们使用时间序列泊松回归模型来估计哮喘就诊与污染水平相关的相对风险（RR）。哮喘病的平均门诊次数在基线时为12.5次/天，在奥运会期间为7.3次/天。与基线相比，奥运会与哮喘就诊显著减少相关（RR 0.54, 95%CI: 0.39-0.75）。我们的分析表明，即使在污染严重的城市。小颗粒浓度的降低与成人哮喘就诊次数的减少有关。(c) 2009 Elsevier B.V.版权所有
To fulfill its commitment to a successful 2008 Olympic and Paralympic Games, the Chinese government made unprecedented efforts to improve the air quality in Beijing. We report findings on air quality and outpatient visits for asthma among adults in Beijing during the 2008 Summer Olympic Games. Three study periods were defined: summer baseline (June 1-June 30: before any air pollution controls), pre-Olympics (July 1-August 7: transportation restrictions in effect), and Olympics (August 8-September 20: further restrictions on industrial emissions). Daily data on outpatient asthma visits were obtained from the asthma registry of Beijing Chaoyang Hospital. We used time-series Poisson regression models to estimate the relative risk (RR) for asthma visits associated with pollution levels. The average numbers of outpatient visit for asthma were 12.5 per day at baseline and 7.3 per day during the Olympics. Compared with baseline, the Games were associated with a significant reduction in asthma visits (RR 0.54, 95%CI: 0.39-0.75). Our analysis showed that even in a heavily-polluted city. decreased concentrations of small particles were associated with some reduction in asthma visits in adults. (c) 2009 Elsevier B.V.
