This study was undertaken to determine whether there was a correlation between fine particle (PM2.5) levels and hospital admissions for hypertension in Taipei, Taiwan. Hospital admissions for hypertension and ambient air pollution data for Taipei were obtained for the period from 2009 to 2013. The relative risk of hospital admissions was estimated using a case-crossover approach, controlling for weather variables, day of the week, seasonality, and long-term time trends. For the single pollutant model (without adjustment for other pollutants), the risk of hospital admissions for hypertension was estimated to increase by 12% on warm days (>23 degrees C) and 2% on cool days (<23 degrees C), respectively. There was no indication of an association between levels of PM2.5 and risk of hospital admissions for hypertension. In two-pollutant model, PM2.5 remained nonsignificant after inclusion of any of the other air pollutants (SO2, NO2, CO, or O-3) both on warm and cool days, but a numerically greater response was seen on warm days. Data thus indicate that in Taipei, hospital admissions for hypertension occur as a consequence of factors not related to ambient air exposure.
