Cognitive Development and Prenatal Air Pollution Exposure in the CHAMACOS Cohort.

ABSTRACT:

Background

Because fine particulate matter [PM, with aerodynamic diameter ≤2.5μm (PM2.5)] is a ubiquitous environmental exposure, small changes in cognition associated with PM2.5 exposure could have great societal costs. Prior studies have demonstrated a relationship between in utero PM2.5 exposure and cognitive development in urban populations, but it is not known whether these effects are similar in rural populations and whether they persist into late childhood.

Objectives

In this study, we tested for associations between prenatal PM2.5 exposure and both full-scale and subscale measures of IQ among a longitudinal cohort at age 10.5 y.

Methods

This analysis used data from 568 children enrolled in the Center for the Health Assessment of Mothers and Children of
