Model 1 – no covariates other than race and ethnicity (referent non-Hispanic white)
Model 2 – adjustment for maternal age, body mass index, smoking, and medical co-morbidities
PTB = preterm birth; iPTB = medically-indicated preterm birth; sPTB = spontaneous preterm birth; HDP=hypertensive disease of pregnancy; SGA = small-for-gestational-age birth; NHB = non-Hispanic black; NHW = non-Hispanic white
