Prenatal air pollution exposure and ultrasound measures of fetal growth in Los Angeles, California.

ABSTRACT:

Background

Few previous studies examined the impact of prenatal air pollution exposures on fetal development based on ultrasound measures during pregnancy.

Methods

In a prospective birth cohort of more than 500 women followed during 1993-1996 in Los Angeles, California, we examined how air pollution impacts fetal growth during pregnancy. Exposure to traffic related air pollution was estimated using CALINE4 air dispersion modeling for nitrogen oxides (NOx) and a land use regression (LUR) model for nitrogen monoxide (NO), nitrogen dioxide (NO2) and NOx. Exposures to carbon monoxide (CO), NO2, ozone (O3) and particles <10μm in aerodynamic diameter (PM10) were estimated using government monitoring data. We employed a linear mixed effects model to estimate changes in fetal size a
