Acute Effects of PM10 on Asthma Hospitalization Among Children and Benefit Analysis at Four Major Cities in Korea

This study assessed the relationships between levels of PM!O and hospitalization rates for asthma among children from 2003 to 2005 at four m에 or cities in Korea. In addition, we estimated the reduced number of asthma hospitaIization asso ciated with an nbiεnt PMlO improvement to thε acceptable levels as recommεnded by the W orld HeaIth Organization(WHO). The GeneraIized Additive Model (GAM) was used to estimatε the relative risks (RR) of asthrna hospitalization associated with changes in PM!O The RRs of children’s asthma hospitalization for every 10 μg/m3 increment in PM1O were 1.009(95% CI = 1.004-1.014) in Seoul, 1.013(95% CI = 1.006-1.021) in Incheon, 1.009(95% CI = 1.002-1.016)in Busan, and 1.021(95% CI = 1.005-1.037) in Ulasn. We assessed PM!O related health benefits from implε， menting the WHO’s guidelines (24-hour average 50 μg/m3 ) using the U.S. Environmεntal Protection Agency s Environmental Benefits Mapping and Analysis Program. Thε estimated benefits wεrε 439(95% CI = 216-666) reduced asthrna hospitaIization in Seoul, 720(95% CI = 304-1,151) in Incheon, 260(95% CI = 66-459) in Busan, and 126(95% CI = 30-228) in Ulsan. It was concluded that improving PM!O condition to the WHO guideline would makε a significant contribution to the reduction in asthrna hospitaIization among children. Therefore, public heaIth measures are still needed to improve air quality in Kmεa
