Data was analyzed using multivariable logistic regression analysis. Models were adjusted for maternal age, height, gravidity, parity, gestational age at delivery, weight gain during pregnancy, cigarette smoke pre-pregnancy, and alcohol consumption pre-pregnancy
Reference group: normal weight for pre-pregnancy
OR odds ratio, CI confidence interval, GH gestational hypertension, PE preeclampsia, GDM gestational diabetes mellitus, PPH postpartum hemorrhage, SGA small for gestational age, LGA large for gestational age, NS the number in this category was too small to analyze
