Outline of Final Research Achievements

This study aims to examine the health effects of air pollutants such as particulate matter 2.5 (PM2.5) on daily admissions by identifying the cause of admission for all causes and each type of cardiovascular, cerebrovascular, and respiratory disease. Relative risks of hospital admissions per unit concentration increase in air pollutants are estimated using time-series Poisson regression models. The result shows that an increase of hospital admissions was observed at an increase of air pollutants: the number of hospital admissions at lag 0 day due to subarachnoid hemorrhage increased at every 10µg/m3 increase in PM2.5.
