Fully adjusted and partially adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for stillbirth among pregnant people in maternal obesity classes I, II, and III, compared with those with normal body mass index, among singleton hospital births in Ontario, Canada, Apr. 1, 2012, to Dec. 31, 2018. The fully adjusted Cox regression model is adjusted for maternal age older than 35 years, nulliparity, smoking, low income quintile, substance use, use of artificial reproductive technologies, chronic hypertension, pre-gestational diabetes, other pre-existing health conditions, previous stillbirth, previous cesarean delivery, antenatal care, small for gestational age (< 10th percentile), gestational diabetes, hypertensive disorders of pregnancy, placental abruption, and congenital fetal anomalies. The partially adjusted Cox regression model is adjusted for maternal age older than 35 years, nulliparity, low income quintile, use of artificial reproductive technologies, other pre-existing health conditions (not including chronic hypertension and pre-gestational diabetes), previous cesarean delivery, and antenatal care (representing the population with additional or undiagnosed high-risk pregnancy factors).
