[Obstetric and neonatal outcomes of adolescent pregnancies: a cohort study in a hospital in Seine-Saint-Denis France].

OBJECTIVES

The aim of this study was to describe the characteristics, monitoring, obstetrical complications, childbirth and neonatal outcomes of pregnancies among minors in a cohort of adolescents from Seine-Saint-Denis (France).

PATIENTS AND METHODS

This is a retrospective, cohort, comparative study, conducted from January 1, 1996 to July 31, 2011, made from the database of Jean-Verdier hospital in Seine-Saint-Denis. Three groups were established: patients aged less than 16 years old, patients aged over 16 years old and under 18 years old compared to a group consisting of older primiparas from 18 to 25 years old. The criteria considered were the characteristics of pregnancy, terms of delivery, neonatal outcome and conduct of post-partum.

RESULTS

Minor patients were statistically more likely to be single, student, smoking and anemia compared to young adults. The obstetrical care was lower for minor compared to the control group with a number of consultations and ultrasounds lower (P < 0.001). Obstetrical complications were similar in the three groups outside of preterm labor. Adolescentes under 16 years old had a higher preterm delivery risk in multivariate analysis (RR = 0.33 CI 95% [0.12; 0.90] P = 0.03). Adolescents had fewer cesarean and instrumental deliveries (P < 0.05).

DISCUSSION AND CONCLUSION

Teenage pregnancy remains an important managing issue for maternities, particularly from a social standpoint. On the medical side, one preterm delivery appears to be more common among these adolescents.
