Prenatal exposure to particulates and anthropometry through 9 years of age in a birth cohort.

ABSTRACT:

Background

Previous research observed links between prenatal air pollution and risk of childhood obesity but the timing of the exposure is understudied.

Aim

We examined prenatal particulate matter (PM₁₀, PM_2.5) exposure and child anthropometry.

Materials & methods

Children's body mass index z-scores (zBMI) at 0-3 (N = 4370) and 7-9 (n = 1191) years were derived from reported anthropometry at paediatric visits. We ran linear mixed models for six windows, adjusting for maternal, child, and neighbourhood factors.

Results

PM₁₀ exposure across pregnancy and at multiple windows was associated with higher zBMI in both early and middle childhood. For instance, one interquartile range increase in PM₁₀ exposure during the first
