[Maternal and perinatal morbidities associated to advanced age in pregnant women].

Background: Women in advanced maternal age (older than 35 years of age) are at higher risk of obstetric complications and adverse perinatal outcomes than younger women.

Objective: To know the maternal and perinatal morbidities associated to advanced age in pregnant women.

Material And Methods: Analytical cross-sectional study. Women with resolution of pregnancy in the medical unit were included and distributed in two groups: group 1, advanced age, ≥ 35 years, and group 2, < 35 years. Clinical data, maternal and perinatal morbidities of the newborn (NB) were collected from the medical record.

Results: We included 240 patients, 120 per group; a significant association of advanced maternal age with maternal morbidities such as diseases prior to pregnancy was demonstrated (p < 0.0001), including diabetes mellitus during pregnancy (p = 0.002), hypertensive disease of pregnancy (p = 0.0001), pregnancy resolution by cesarean section (p = 0.04), obstetric hemorrhage (p = 0.0002), prenatal control with < 5 consultations (p = 0.008), as well as those with perinatal morbidities of the NB: preterm gestational age (p = 0.001), intrauterine growth retardation (p = 0.01), low weight for gestational age (p = 0.001) and admission of the NB to the neonatal intensive care unit (p = 0.007); with multivariate analysis, an association of advanced maternal age with diabetes mellitus, hypertensive disease of pregnancy and obstetric hemorrhage was observed (R2 = 0.9884; p < 0.0001).

Conclusion: The maternal and perinatal morbidities are associated with advanced age in pregnant women.
