Area of Science:

  • Obstetrics and Gynecology
  • Reproductive Medicine
  • Maternal-Fetal Medicine

Background:

  • Advanced maternal age (≥ 35 years) is linked to reduced fertility and increased pregnancy/neonatal complications.
  • This study investigates maternal and fetal outcomes and risk perception in pregnancies after 35.

Purpose of the Study:

  • To analyze maternal and fetal consequences of advanced maternal age.
  • To assess maternal perception of pregnancy risk after 35.

Main Methods:

  • Retrospective comparative study of 153 women aged ≥ 35 and 153 women aged < 35.
  • Statistical analysis included Chi-square and Fisher's exact tests (p < 0.05 significance).

Main Results:

  • Advanced maternal age group had more primiparous women, previous miscarriages, assisted reproductive technology use, amniocentesis, and dystocia (including C-sections).

  • No significant association found for maternal complications, birth defects, neonatal resuscitation, or prematurity.
  • Women under 35 perceived pregnancy risk as higher.

    • Conclusions:

    • Term deliveries in advanced maternal age pregnancies often occur without complications.
    • Neonatal outcomes were not significantly influenced by advanced maternal age in this cohort.
    • Future definitions of advanced maternal age may shift to 40 years.
