Background: Particulate matter < 2.5 micrometers in aerodynamic diameter (PM2.5) has been variably associated with preterm birth (PTB).
Objective: We classified preterm births into four categories (20–27, 28–31, 32–34, and 35–36 weeks completed gestation) and estimated risk differences (RD) for each category in association with a 1-µg/m3 increase in PM2.5 exposure during each week of gestation.
Methods: We assembled a cohort of singleton pregnancies that completed at least 20 weeks of gestation during 2000-2005 using live birth certificate data from three states (Pennsylvania, Ohio, and New Jersey) (n = 1,940,213; 8% PTB). We estimated mean PM2.5 exposures for each week of gestation from monitor-corrected Community Multi-Scale Air Quality modeling data. RDs were …
