Gestational diabetes and preeclampsia in association with air pollution at levels below current air quality guidelines.

ABSTRACT:

Background

Several studies have estimated associations between air pollution and birth outcomes, but few have evaluated potential effects on pregnancy complications.

Objective

We investigated whether low-level exposure to air pollution is associated with gestational diabetes and preeclampsia.

Methods

High-quality registry information on 81,110 singleton pregnancy outcomes in southern Sweden during 1999-2005 was linked to individual-level exposure estimates with high spatial resolution. Modeled exposure to nitrogen oxides (NOx), expressed as mean concentrations per trimester, and proximity to roads of different traffic densities were used as proxy indicators of exposure to combustion-related air pollution. The data were analyzed by logistic regression, with and without
