Neonatal and maternal morbidity rates in low-risk nulliparous women across different gestational ages

This study examines perinatal outcomes in low-risk nulliparous women and their neonates across different gestational ages. Using data from 18 hospitals, we analyzed maternal and neonatal complications for deliveries at 37-38 weeks, 39-40 weeks, and 41 weeks, focusing on the risks associated with early- and late-term deliveries. Neonatal complications were highest at 37-38 weeks, while maternal complications, primarily anemia, were more prevalent at 41 weeks. These findings suggest that deliveries closer to 39-40 weeks may offer optimal outcomes for maternal and neonatal health. By providing insights into the impact of gestational timing, this study aids clinical decision-making for safe delivery timing, potentially improving perinatal outcomes for low-risk pregnancies.
