Adverse Perinatal Outcomes Associated with Increasing Maternal Obesity.

Higher preconceptional BMI was significantly associated with adverse neonatal metrics including decreased weeks of gestational age, preterm birth, lower 1- and 5-minute Apgar scores, and postdelivery length of stay ( Table 1 ). Associations remained significant in multivariable logistic regression models for gestational diabetes, preeclampsia, cesarean delivery adjusting for advanced maternal age, preexisting maternal hypertension, preexisting maternal diabetes, gestational age, and prior c-section ( Table 2 ). All the maternal metrics demonstrated a significant trend except for age at time of delivery and ICU admission.
