Ambient pollutants and urgent visits for asthma

Pediatric asthma is a chronic, heterogeneous disease that can be triggered by environmental exposures, leading to urgent medical visits. Numerous studies have demonstrated increases in emergency department visits and hospitalizations in association with increasing concentrations of outdoor ambient pollutants. Social and environmental stressors have also been shown to be associated with a stronger relationship between environmental pollutants and asthma development and symptoms. In this study, Dr Lovinski-Desir from Columbia University Medical Center and her team aimed to determine if the relationship between ambient pollutants and urgent visits for asthma varied between New York City neighborhoods with high versus low asthma prevalence.
