Multivariate logistic regression adjusted for maternal age, race, body mass index at delivery, nulliparity, education level, insurance type, household income and marital status. aOR were only reported if the outcome of interested had a minimum number of events reported (80) thus allowing 8 adjustors to be used. Bolded if significantly different.
Composite neonatal morbidity includes: 5-minute Apgar score ≤ 3, respiratory distress syndrome (RDS), use of ventilator/CPAP, suspected newborn sepsis, seizure, stillbirth, or neonatal death.
