The objective of this study is to see whether there were any health benefits of mitigated air pollution concentration due to reduced traffic flow during a citywide intervention for the 2002 Summer Asian Games. Relative risks of hospitalization for childhood asthma during the post-Asian Game period compared with the baseline period were estimated using a time-series analysis of the generalized additive Poisson model. Fourteen consecutive days of traffic volume control in Busan during the Games reduced all regulated air pollutant levels by 1-25%. The estimated relative risk of hospitalization during the post-Games period over the baseline period was 0.73 (95% confidence interval [CI] = 0.49, 1.11). We observed that this reduced air pollution was unique in 2002 when the traffic volume reduction program was applied during the Games period. This empirical data provides epidemiologic evidence of the health benefits resulting from environmental interventions to reduce ambient air pollution.
本研究的目的是观察在2002年夏季亚运会全市范围干预期间，交通流量减少导致空气污染浓度降低是否对健康有益。通过广义相加泊松模型的时间序列分析，估计亚运会后时期与基线时期相比儿童哮喘住院的相对风险。亚运会期间釜山连续14天的交通流量控制使所有受监管的空气污染物水平降低了1%-25%。与基线时期相比，亚运会后时期住院的估计相对风险为0.73（95%置信区间[CI]=0.49,1.11）。我们观察到，2002年在亚运会期间实施交通流量减少计划时，空气污染的减少是独一无二的。这一经验数据为减少环境空气污染的干预措施对健康有益提供了流行病学证据。
