Model D includes age, birth year, insurance status, marital status. Model E includes covariates in Model D, plus smoking in pregnancy, alcohol use in pregnancy, pre-pregnancy BMI, prior stillbirth, stillbirth risks in prior pregnancy (previous c-section, prior preterm birth), current risks (small for gestational age, preterm birth, placental abruption), preconception chronic disease (asthma, hypertension, diabetes). Model F includes covariates in Model E, plus current area-level percent poverty, change in poverty from 1990 to birth year, exposure to ozone, and temperature.
