Risk factors of teenage pregnancies, deliveries and post-partum in the department of Loiret

Objective To evaluate the obstetric outcome of teenage pregnancies compared to adult women in the department of Loiret. Methods A retrospective study of adolescents (10-19 years) delivered after 22 weeks compared to adult women aged 20-35 years (controls) from the first January to the 31 December 2012 in a maternity level 3. The two groups were compared by the Chi2 test or the exact test of Fisher. A P-value < 0.05 was considered significant. Results Adolescent had less prenatal consultations than controls (4 versus 7). They used more tobacco during pregnancy than adult controls. Urinary infections and preterm threat and births were more frequent in the adolescent group compared to the controls (P = 0.04 and 0.018). However, the gestational diabetes was less frequent in the adolescent group versus controls (P = 0.0005, OR: 0.16 [IC95%: 0.03-0.54]). The adolescent group represented 2.38 of total deliveries. The rate of vaginal deliveries and caesarean section was similar in the two groups. Vaginal tears were significantly more frequent among adolescents than controls (P = 0.0019). Conclusion The adolescents were more likely to preterm delivery and to have urinary infections than the adult women (controls). They are less likely to have gestational diabetes than older women. The rates of vaginal deliveries are comparable; however, the adolescents are more likely to experience vaginal tears than controls.
