This analysis suggests that traffic is a contributor to more acute asthma episodes in children.
While previous studies have found associations between traffic-related air pollution and asthma attacks in children, these studies were mainly conducted in emergency department or hospital admission settings; little is known regarding less acute health effects. This analysis, conducted in a primary care setting, found that both larger traffic volumes and smaller distances to the nearest major roadway were significantly associated with larger numbers of childhood asthma visits, when compared with less traffic and larger distances. The findings point to motor vehicle traffic as an important contributor to childhood asthma exacerbations.
