- Model adjusted for infant’s sex, maternal age, pre-pregnancy maternal body mass index (BMI), maternal educational level, maternal smoking during first 3 months of pregnancy, and environmental tobacco smoke exposure during pregnancy.
- arepresents the increase in odds of PTB for a per IQR increase in PM10 exposure;
- brepresents the increase in odds of TLBW for a per IQR increase in PM10 exposure;
- crepresents the increase in odds of SGA for a per IQR increase in PM10 exposure
