Database Draws Connections between Traffic Proximity and Asthma Exacerbations

In the November 2016 edition of Environmental Health, researchers examined the connection between asthma exacerbations and proximity to traffic. The authors used the Rochester Epidemiology Project (REP), “a unique community-based medical record data linkage system that provides individual patient address, diagnosis and visit information for all hospitalizations, as well as emergency department, urgent care and outpatient clinic visits for asthma.” Traffic exposure metrics were compared against “spatial coordinates of the homes of 19,915 individuals diagnosed with asthma.”

The results indicated that “asthma exacerbations increased as traffic levels near the home increased. Proximity to traffic was a significant predictor of asthma exacerbations in logistic and Poisson regressions controlling for age, gender and block group poverty.”
