Traffic-Related Air Pollution Increases Risk of Hospital Readmission for Asthma

Higher exposure to traffic-related air pollution (TRAP) increases the odds of readmission to the hospital for asthma – but only for white children, according to a new Cincinnati Children’s Hospital Medical Center study.

White children exposed to high levels of TRAP are three times more likely to be readmitted for asthma than white children with low TRAP exposure. However, levels of TRAP exposure were not associated with increased risk of readmission of black children.

“Although black children in our study had a higher rate of asthma readmission overall, TRAP exposure was not a discernible factor for these children,” says Nicholas Newman, DO, a pediatrician at Cincinnati Children’s and lead author of the study.
