Prenatal and early life exposures to ambient air pollution and development.

ABSTRACT:

Background

Residential proximity to major roadways, and prenatal exposures to particulate matter <2.5 μm (PM_2.5) and ozone (O₃) are linked to poor fetal outcomes but their relationship with childhood development is unclear.

Objectives

We investigated whether proximity to major roadways, or prenatal and early-life exposures to PM_2.5 and O₃ increase the risk of early developmental delays.

Study design

Prospective cohort.

Settings

New York State excluding New York City.

Participants

4089 singletons and 1016 twins born between 2008 and 2010.

Exposures

Proximity to major roadway was calculated using road network data from the NY Department of Transportation. Concentrations of PM_2.5 and O₃
