Abstract：
OBJECTIVE:The purpose of this study was to describe trends and outcomes of planned births. STUDY DESIGN:Data from linked birth and hospital records for 779,521 singleton births at ≥33 weeks' gestation from 2001-2009 were used to determine trends in planned births (prelabor cesarean section and labor inductions). Adverse outcomes were composite indicators of maternal and neonatal morbidity/death. RESULTS:From 2001-2009, there were increases in labor inductions and prelabor cesarean deliveries at <40 weeks' gestation, but no decrease in the stillbirth rate (trend P = .34). By 2009, 14.9% of live births at ≥33 weeks' gestation were prelabor cesarean deliveries before the due date; 11.4% were inductions. As planned births increased, maternal risks shifted, which included a decline in inductions with maternal hypertension from 31.9-23.9%. Earlier birth was contemporaneous with increases (trend P < .001) in neonatal and maternal morbidity rates from 3.0-3.2% and 1.1-1.5%, respectively. CONCLUSION:Planned birth before the due date is increasing without a contemporaneous reduction of stillbirths.
