Associations between weekly maternal exposure to ambient particulate matter and congenital heart disease.

ABSTRACT:

Background

The association between maternal exposure to air pollution and congenital heart diseases (CHDs) has garnered increasing attention. However, investigations into critical weekly specific exposure windows for CHDs remain limited. This study evaluated the relationship between maternal ambient particulate matter exposure throughout the entire pregnancy period and the risk of CHDs, as well as explored critical weekly specific exposure windows.

Method

Based on the Jiangsu Maternal and Child Health Monitoring Manual and the Environmental Health Department of Suzhou CDC, 19,914 pregnant women with complete hospital delivery records between 2021 and 2023 were included, and the concentration data for five air pollutants (PM₁₀, PM_2.5, NO₂, CO,
