Prenatal exposure to air pollutant mixtures and birthweight in the upstate KIDS cohort.

ABSTRACT:

Background

Single-pollutant models have linked prenatal PM_2.5 exposure to lower birthweight. However, analyzing air pollutant mixtures better captures pollutant interactions and total effects. Unfortunately, strong correlations between pollutants restrict traditional methods.

Objectives

We explored the association between exposure to a mixture of air pollutants during different gestational age windows of pregnancy and birthweight.

Methods

We included 4,635 mother-infant dyads from a New York State birth cohort born 2008-2010. Air pollution data were sourced from the EPA's Community Multiscale Air Quality model and matched to the census tract centroid of each maternal home address. Birthweight and gestational age were extracted from vital records. We applied
