The relationship between air pollutants and maternal socioeconomic factors on preterm birth in California urban counties.

ABSTRACT:

Background

Preterm birth is the leading cause of perinatal morbidity and mortality in the U.S. and disparities among racial and ethnic groups persist. While etiologies of preterm birth have not been fully elucidated, it is probable that environmental and social factors play a role.

Objective

We hypothesized that there is an interactive association between exposure to fine particulate matter (PM_2.5) or ozone (O₃) and neighborhood socioeconomic factors that increase the risk of preterm birth.

Methods

We conducted a retrospective study using geocoded birth certificate data between 2007 and 2011, daily ambient air quality data on PM_2.5 and O₃, and American Community Survey (2007-2011 5-year estimates) data to assess census tract
