Associations Between Ambient Air Pollutant Concentrations and Birth Weight: A Quantile Regression Analysis.

ABSTRACT:

Introduction

We investigated the extent to which associations of ambient air pollutant concentrations and birth weight varied across birth weight quantiles.

Methods

We analyzed singleton births ≥27 weeks of gestation from 20-county metropolitan Atlanta with conception dates between January 1, 2002 and February 28, 2006 (N = 273,711). Trimester-specific and total pregnancy average concentrations for 10 pollutants, obtained from ground observations that were interpolated using 12-km Community Multiscale Air Quality model outputs, were assigned using maternal residence at delivery. We estimated associations between interquartile range width (IQRw) increases in pollutant concentrations and changes in birth weight using quantile regression.

Results

Gestational age-adjusted
