ABSTRACT
Objective@#Many previous studies have reported relationships between particulate matter 80 μg/m3, and the PM10 values on the 5 following days were recorded. To assess the cumulative effects of PM10, we calculated relative risk (RR) by analyzing the cumulative effects over 6 days (lag days 0 to 5). @*Results@#Asthma, COPD, and ischemic stroke patients (< 65 years old) showed a positive correlation between PM10 (asthma on lag day 5 RR, 2.587; 95% confidence interval [CI], 2.001-3.344; COPD on lag day 4 RR, 3.727; 95% CI, 2.988-4.650; and ischemic stroke on lag day 4 RR, 1.573; 95% CI, 1.168-2.118). MI in those≥65 showed the highest RR on lag day 1 (RR, 1.471; 95% CI, 1.042-2.077). Hemorrhagic stroke was not found to be significantly correlated with PM10 in either age group. @*Conclusion@#An increase in PM10 is associated with ED visits by patients<65 years old with asthma, COPD, or ischemic stroke, and with MI for those≥65 years.
