INTRODUCTION Environmental factors play a critical role in the progression or resolution of chronic respiratory diseases. However, studies are limited on the impact of environmental risk factors on individuals born prematurely with lung disease after they leave the neonatal intensive care unit and are discharged into the home environment. AREAS COVERED In this review we cover current knowledge of environmental exposures that impact outcomes in preterm respiratory disease, including air pollution, infections, and disparities. The limited data do suggest that certain exposures should be avoided and there are potential preventative strategies for other exposures. There is a need for additional research outside of the neonatal intensive care unit that focuses on individual and community-level factors that affect long term outcomes. EXPERT OPINION Preterm respiratory disease can impose a significant burden on infants, children, and young adults born prematurely, but may improve for many individuals over time. In this review we outline the exposures that may potentially hasten, delay, or prevent resolution of lung injury in the preterm child.
