Association between fine particulate matter (PM2.5) and violence cases in South Korea: A nationwide time-stratified care-crossover study.

ABSTRACT: Several studies reported the roles of short-term exposure to fine particulate matter (PM2.5) on violent behaviors; however, existing findings had a limitation in assessing the population-representative association between violence and PM2.5 due to the limited data availability: most studies have been based on homicides in monitored urban areas. This study collected violence data from the National Hospital Discharge In-depth Injury Survey in South Korea (2015-2019), based on population-representative samples. To cover unmonitored areas, we used the daily modeled PM2.5, the predicted result driven by a machine-learning ensemble model covering all inland districts in South Korea (R2>0.94). We evaluated the national association between short-term exposure to PM2.5 and violence cases with a tim
