Associations of acute exposure to fine and coarse particulate matter and mortality among older people in Tokyo, Japan

Recent studies have reported adverse health effects of short-term exposure to coarse particles independent of particulate matter less than 2.5μm in diameter (PM2.5), but evidence in Asian countries is limited. We therefore evaluated associations between short-term exposure to particulate matter (PM)...

Description
Summary:Recent studies have reported adverse health effects of short-term exposure to coarse particles independent of particulate matter less than 2.5μm in diameter (PM2.5), but evidence in Asian countries is limited. We therefore evaluated associations between short-term exposure to particulate matter (PM) and mortality among older people in Tokyo, Japan. We used a time-stratified, case-crossover design. Study participants included 664,509 older people (≥65years old) in the 23 urbanized wards of the Tokyo Metropolitan Government, who died between January 2002 and December 2013. We obtained PM2.5 and suspended particulate matter (SPM; PM
