BACKGROUND Previous studies on the effects of acute air pollution have focused primarily on blood pressure (BP). METHODS Our study enrolled 9238 nonsmoking adults over 30 years of age from 6 townships in Taiwan: 1 seaport, 1 urban, 1 industrial, and 3 rural. Using generalized additive models, we evaluated the associations between brachial BP and(More)
The associations between fine particulate matter (PM2.5) and stroke remain inconsistent. We conducted a time-series study to evaluate emergency room (ER) visits for ischemic and hemorrhagic strokes in relation to PM2.5 and its constituents. Generalized additive models were used to model the counts of daily ER visits for ischemic and hemorrhagic strokes(More)
Particulate matter with aerodynamic diameter of <2.5 μm (PM2.5) is associated with blood pressure and hemodynamic changes. Blunted nocturnal blood pressure dipping is a major risk factor for cardiovascular events; limited information is available on whether PM2.5 exposure-related hemodynamic changes vary with day-night blood pressure circadian rhythms.
