Initiatives to encourage delaying deliveries until a gestational age of 39 weeks appear to have slowed the increases but have not led to declines. The rates are at historic highs and the consequences of these interventions when not medically necessary have not been systematically explored at the population level. In this study, we used population-level data on births in New Jersey (1997-2011) to document trends in elective deliveries (induced vaginal delivery, cesarean delivery with no labor trial, and cesarean delivery after induction) and estimate logistic and linear regression models of associations between delivery method andAmerican journal of epidemiologyElective Deliveries and Neonatal Outcomes in Full-Term Pregnancies.PMC6438816P2C HD058486R01 HD090119P2CHD058486R01HD090119Hegyi TPlaza RReichman NETeitler JOKruse LfalseElective Deliveries and Neonatal Outcomes in Full-Term Pregnancies.Cesarean and induced delivery rates have risen substantially in recent decades and currently account for over one-third and one-fourth of US births, respectively.
