Associations of PM_2.5 exposure with emergency department visits and readmissions among preterm infants with bronchopulmonary dysplasia.

ABSTRACT:

Objectives

To quantify the association of ambient air pollution (particulate matter, PM_2.5) exposure with medically attended acute respiratory illness among infants with bronchopulmonary dysplasia (BPD).

Study design

Single center, retrospective cohort study of preterm infants with BPD in Metropolitan Philadelphia. Multivariable logistic regression quantified associations of annual mean PM_2.5 exposure (per μg/m³) at the census block group level with medically attended acute respiratory illness, defined as emergency department (ED) visits or hospital readmissions within a year after first hospital discharge adjusting for age at neonatal intensive care unit (NICU) discharge, year, sex, race, insurance, BPD severity, and census tract deprivation
