The impact of maternal age on pregnancy outcome in singleton pregnancies

Abstract Objective: To identify the impact of maternal age on pregnancy outcome in singleton gestations without a maternal history of previous preterm delivery. Study design: We retrospectively identified women who presented with preterm labor in the current pregnancy andsubsequently delivered between July 1995 and February 2000. Included were those with documented pregnancy outcome who delivered at ≥24 weeks of gestation. Data were analyzed as four age groups: Results: Pregnancy outcome was analyzed in 22,975 women. Overall, 38.4% experienced preterm delivery. There were no significant differences across the groups in the incidence of delivery because of spontaneous labor at >37 weeks of gestation. Significant findings are summarized in the table (all P 2 ). 20–34 35–39 ≥40 n = (2,061) 17,362) (2,961) (591) Delivery 46.5% 37.6% 36.6% 37.1% Delivery 6.1% 4.4% 5.9% 7.1% PTL @ delivery 36.0% 26.8% 23.4% 23.5% Cesarean delivery 11.3% 21.9% 32.3% 35.8% Conclusion: Our findings suggest that maternal age
