영문 초록

This study investigated the age dependencies on ambient air pollution-associated asthma hospitalization in Seoul in 2003-2005. For all ages and the age groups of 0-14, 15-64, and 65+years, the Generalized Additive Model (GAM) was used to estimate the relative risk of daily asthma hospitalization associated with changes in particulate matter and ozone. The time-trends, seasonal variances, day effects, temperature, humidity, and pressure at sea level were controlled in the models. Significant associations were observed between asthma hospitalization and the levels of PM10, and O₃. The relative risks (RRs) of asthma hospitalization for every 10 unit increases in PM10(㎍/m³) and O3(ppb) were 1.008 (95% CI 1.005-1.012), and 1.012 (95% CI 1.003-1.020), respectively. Evaluated over 10㎍/m³ increase in PM10, we found the relative risks of asthma hospitalization to be 1.009 (95% CI 1.004-1.014) in 0-14 age group, and 1.015 (95% CI 1.008-1.022) in 65+ age group. Considering 10 ppb increase in O3, those were 1.012 (95% CI 1.003-1.020) in 0-14 age group, and 1.025 (95% CI 1.09-1.041) in 65+ age group. It was concluded that current levels of ambient air pollution in Seoul make a significant contribution to the variation in daily asthma hospitalization. Further reduction in air pollution is necessary to protect the health of the community, especially that of the higher risky groups including children and elderly population.
