Summary

Late maternal age in postdate pregnancies is linked to poorer infant outcomes and more cesarean births. However, exceeding 42 weeks gestation remains safe for women over 35.

Area of Science:

Maternal-Fetal Medicine

Background:

Postdate pregnancies, defined as those extending beyond 42 weeks gestation, require careful management.
Maternal age is a known factor influencing pregnancy outcomes.

Purpose of the Study:

To investigate the impact of advanced maternal age (over 35 years) on pregnancy outcomes in postdate pregnancies.
To assess risks associated with postdate infants born to older mothers.

Main Methods:

Retrospective chart review of 443 postdate pregnancies.
Comparison of pregnancy outcomes between women aged over 35 and younger women.

Main Results:

Significantly higher rates of low 1-minute Apgar scores observed in older mothers.
Increased incidence of intrapartum decelerations and cesarean sections in women over 35.
Similar oxytocin use and 5-minute Apgar scores across age groups.

Conclusions:

Women over 35 experience suboptimal outcomes with postdate infants.
Allowing pregnancies to extend beyond 42 weeks gestation is considered safe for older mothers despite increased risks.
