The Health Insurance Research Database from the National Health Research Institutes, and air pollutants data from 11 air quality monitoring stations in Central Taiwan Air Basin were collected and analyzed. Generalized additive models are employed to regress the daily numbers of respiratory and circulatory outpatients and daily mean concentrations of the air pollutants. The relative risks (RR) of outpatients per IQR increase in the concentration of each air pollutant are also estimated. The results show that the air pollutants in lag0 or lag1 have the most significant impacts on respiratory diseases. CO (RR, 1.0399, 95% CI, 1.0272-1.0407), NO2 (RR, 1.0535, 95% CI, 1.0462-1.0608), SO2 (RR, 1.0225, 95% CI, 1.0193-1.0257), PM10 (RR, 1.0372, 95% CI, 1.0303-1.0441), PM2.5 (RR, 1.0312, 95% CI, 1.0245-1.0379) and O3 (RR, 1.0009, 95% CI, 1.0006-1.0012) are significantly associated with total respiratory diseases and lower respiratory diseases. CO and NO2 are significantly associated with COPD. However, the six pollutants have no significant effect with asthma. For different aged groups, the 65+ aged group has the highest RR in respiratory diseases while the 15-65 aged group has the highest RR in lower respiratory diseases. In addition, CO (RR, 1.0352, 95% CI, 1.0233-1.0473), NO2 (RR, 1.0545, 95% CI, 1.0412-1.0675), SO2 (RR, 1.0297, 95% CI, 1.0240-1.0355), PM10 (RR, 1.0414, 95% CI, 1.0290-1.0539), and PM2.5 (RR, 1.0302, 95% CI, 1.0184-1.0422) are significantly associated with circulatory and cardiovascular diseases. The 65+ aged group has the highest RR in circulatory diseases while the 15-65 aged group has the highest RR in cardiovascular diseases.
