Prenatal Exposure to Air Pollution and Respiratory Distress in Term Newborns: Results from the MIREC Prospective Pregnancy Cohort.

ABSTRACT:

Background

Respiratory distress is the leading cause of neonatal morbidity and mortality worldwide, and prenatal exposure to air pollution is associated with adverse long-term respiratory outcomes; however, the impact of prenatal air pollution exposure on neonatal respiratory distress has not been well studied.

Objectives

We examined associations between prenatal exposures to fine particular matter (PM2.5) and nitrogen dioxide (NO2) with respiratory distress and related neonatal outcomes.

Methods

We used data from the Maternal-Infant Research on Environmental Chemicals (MIREC) Study, a prospective pregnancy cohort (n=2,001) recruited in the first trimester from 10 Canadian cities. Prenatal exposures to PM2.5 (n=1,321) and NO2 (n=1,064) were estimated using land-use re
