Prenatal PM_2.5 exposure and behavioral development in children from Mexico City.

ABSTRACT:

Background

Childhood exposure to air pollution has been linked with maladaptive cognitive development; however, less is known about the association between prenatal fine particulate matter (PM_2.5) exposure and childhood behavior.

Objectives

Our aim was to assess the association between prenatal PM_2.5 exposure and behavioral development in 4-6 year old children residing in Mexico City.

Methods

We used data from 539 mother-child pairs enrolled in a prospective birth cohort in Mexico City. We estimated daily PM_2.5 exposure using a 1 km² satellite-based exposure model and averaged over each trimester of pregnancy. We assessed childhood behavior at 4-6 years of age using the parent-completed Behavioral Assessment Scale for Childr
