Adverse perinatal outcome in teenage pregnancies: an analysis of a 5-year period in Southeastern Hungary

Abstract

Objective: To determine the risks of adverse perinatal outcomes of teenage mothers.Material and methods: A retrospective analysis was performed on teenage mothers (under 20 years of age) who delivered in the period of 2010–2014 at the Department of Obstetrics and Gynecology, University of Szeged (study group). All mothers who delivered in Hungary during the same period were studied as a control group. The following parameters were analyzed: demographic data of the mothers, maternal complications, perinatal outcome and congenital malformations of the newborns. The binominal test, Student’s t-test and Poisson’s regression were applied using STATA 9.0 (StataCorp, College Station, TX, USA) statistical software (p < .05 was considered to be statistically significant).Results: During this 5-year period, 12,845 births were recorded at the Department, of these 274 (2.1%) were teenage pregnancies with 275 newborns. The offsprings of teenage mothers had significantly lower mean birth weight (3110.2 ± 564.03 g versus 3247 g), higher rate of congenital malformations (8.0 versus 5.0%) and higher admission to neonatal intensive care unit (12.4 versus 8.0%) than the infants in the control group.Conclusions: Younger maternal age was significantly associated with lower mean birth weight, higher risk of congenital malformations, and increased admission rate to neonatal intensive care unit.
