OBJETIVE:

To describe and compare the influence of maternal age on maternal and perinatal outcomes.

MATERIALS AND METHODS:

Observational, retrospective, single-center, retrospective study in which all deliveries that occurred in the year 2020 in a Spanish hospital were collected. The age of the women was categorized into three groups (1: under 35 years; 2: more or less older than 35 years and younger than 40 years; 3: older than 40 years).

RESULTS:

A study population of 1700 women was assembled and found a clear correlation between advanced maternal age and risk of cesarean section and a nonsignificant trend toward a higher number of instrumented deliveries. Advanced maternal age is a risk factor for various pregnancy-related diseases and poor perinatal outcomes. Since the current trend shows an increase in this type of pregnancies, it is essential to know the obstetric risks in order to correctly inform and advise pregnant women and to carry out the pertinent actions to avoid the most frequent complications.

CONCLUSIONS:

There is a higher rate of caesarean section in advanced age pregnancies after the confounding factors were adjusted. Fetal outcomes are not affected by maternal age, as well as other perinatal events.
