Numerous epidemiological studies have shown stronger associations between PM<SUB>2.5</SUB> and both mortality and morbidity than PM₁?. The association of PM<SUB>2.5</SUB> with respiratory mortality was examined in Seoul, during the period of 1996~2002. Because PM<SUB>2.5</SUB> data were available for only 10% of this time period, a prediction regression model was developed to estimate PM<SUB>2.5</SUB> concentration. Death count due to respiratory-related diseases (total respiratory mortality; ICD-10, J00-J98) and death counts (cause-specific mortality) due to pneumonia (ICD-10, J12-J18), COPD (ICD-10, J40-J44) and asthma (ICD-10, J45-J46) were considered in this study. Averaged daily mortality was 5.6 for total respiratory mortality and 1.1 to 1.6 for cause-specific mortality.
Generalized additive Poisson models controlling for confounders were used to evaluate the acute effects of particle exposures on total respiratory mortality and cause-specific mortality. An IQR increase in 5-day moving average of PM<SUB>2.5</SUB> (22.6 μg/㎥) was associated with an 8.2% (95% CI: 4.5 to 12.1%) increase in total respiratory mortality. The association of PM<SUB>2.5</SUB> was stronger for the elderly (≥65 years old, 10.1%, 95% CI: 5.8 to 14.5%) and for males (8.9%, 95% CI: 2.1 to 11.3%). A 10-μg/m3 increase in 5-day moving average of PM2.5 was strongly associated with total respiratory mortality in winter (9.5%, 95% CI: 6.6 to 12.4%), followed by spring (3.1%, 95% CI: -1.2 to 7.5%), which was a different pattern with the finding in North American cities. However, our results are generally consistent with those observed in recent epidemiological studies, and suggest that PM<SUB>2.5</SUB> has astronger effect on respiratory mortality in Seoul.
