Introduction. In Argentina, 18.3% of all births are related to adolescent mothers. Adolescent pregnancy has been associated with an increase of adverse perinatal outcomes. Placental examination helps to identify etiology and predict recurrence of perinatal pathologies. The aim of this study was to describe placental weight and placental lesions and to estimate the risks of adolescent pregnancies compared with young adults mothers.
Methods. We examined 50 placentas from adolescent mothers (<16 yrs, n = 18 and 17-19 yrs, n = 32) and 101 placentas from adults mothers between 20 and 29 years old attending the Sarda’ Maternity Hospital of Buenos Aires, Argentina. Conventional methods were used for macroscopic and histological examination.
Results. No differences were found in placental weights. In half of examined placenta one or more lesions were present, predominantly in adolescents (p = 0.327). In < 16 ys placental lesions represented 77.78 % (14/18, 95% CI 54 – 91), in older teenagers 34.3% (11/32, 95% CI 20 – 51) (OR 2.26, 95% CI 1.32 – 3.38, p = 0.003), whereas in young adults figure was 41.5% (42/101, [95% CI 32 – 51]), a 1.87 (IC 95% 1.33 – 2.62, p = 0.004) and 0.83 (IC 95% 0.49 – 1.41, p = 0.469) crude risks of both adolescents’ groups compared with adults, respectively.
Adjusted risk for placental lesions was four folds higher in adolescent at or below 16 years (p = 0.018).
Conclusions. No differences were found in placental weights Younger teenagers (? 16 year age) have an increased risk for having placental lesions.
