We aimed to determine the association between young maternal age at delivery with adverse pregnancy outcome in a single, tertiary, university-affiliated medical center.


A retrospective, cohort, matched control study using the first percentile distribution of maternal age at delivery (21 years old, n = 461) as the study group, and four control groups by maternal age matched by parity in a 2:1 ratio (22-25, 26-30, 31-35 and 36-40 years; n = 922 each).


Women aged ≤21 years were found to have lower rates of chronic hypertension [compared with women aged 36-40 years old (0.0% versus 1.3%, p < 0.05)], lower rates of gestational diabetes mellitus (GDM) (1.3% versus 3.7%, p = 0.007), higher rates of perineal lacerations [compared with women aged 31-35 and 36-40 years old, 41% versus 31.8% and 31.1%, respectively, p < 0.01)], higher rates of postpartum hemorrhage (4.6% versus 1.5%, p < 0.0001) and higher rates of low 5-min Apgar score (2.2% versus 0.8%, p = 0.004). No significant differences were found in terms gestational age at delivery, birth weight, fetal sex, intrapartum or antepartum mortality.


Young maternal age at delivery is associated with increased risk of short-term complications after delivery.
