Fine Particulate Matter Constituents Associated With Emergency Room Visits for Pediatric Asthma: A Time-Stratified Case–Crossover Study in an Urban Area
Abstract:Background: Global asthma-related mortality tallies at around 2.5 million annually. Although asthma may be triggered or exacerbated by particulate matter (PM) exposure, studies investigating the relationship of PM and its components with emergency department (ED) visits for pediatric asthma are limited. This study aimed to estimate the impact of short-term exposure to PM constituents on ED visits for pediatric asthma. Methods: We retrospectively evaluated non-trauma patients aged younger than 17 years who visi… Show more
