Association between ambient particulate matter concentration and fetal growth restriction stratified by maternal employment.

ABSTRACT:

Background

Fetal growth has been known to be associated with particulate matter (PM) air pollution during gestation. Given that regular working may deviate outdoor air pollution exposure, the association between air pollution and fetal growth restriction can be different across maternal working status. This study was to assess possible effect modification by maternal employment in the association between exposure to PM during pregnancy and fetal growth restriction.

Methods

Using hourly PM less than or equal to 10 and 2.5 μm in diameter (PM₁₀ and PM_2.5) regulatory monitoring data for 2001-2012 and 2008-2012, respectively, and birth certificate data for 2002-2012, we computed maternal exposures with district-level averages of PM₁₀ and PM_2.
