Charts of 443 postdate pregnancies were reviewed to determine the effect of late maternal age on pregnancy outcome. There were significantly more low 1-minute Apgar scores, intrapartum decelerations, and cesarean sections in the group of women greater than 35 years old. ⋯ Five-minute Apgar scores also were similar. Women greater than 35 years of age are less able to be delivered of postdate infants with optimal outcomes, but it is still safe to allow them to exceed 42 weeks' gestation.
