Reembarazo en la adolescencia: Análisis de la población perteneciente a la Red del Hospital Padre Hurtado, entre los años 2005-2015

Abstract

Objective: To evaluate the prevalence of multiparous adolescents, in the population that had their births at Hospital Padre Hurtado. Methods: Retrospective cohort study, with information taken from the electronic database of the center, Birth data and Interventions, between 2005 and 2015. The data was tabulated in Microsoft Excel and the analysis was done with IBM SPSS 22 version. Results: It occurred 62,656 deliveries and 5,770 pregnancies that ended in an intervention, from the total, 14,030 (20.5%) occurred in girls under 20 years and 356 (0.52%) under 15 years old (yo). The number of multiparous was 940 (10.3% of all of the adolescent pregnancies). For first time pregnants under 15 yo, 68 had a reiterative pregnancy among their adolescence (19.3% of pregnant <15 yo). The median time between pregnancies was 3 years (range 1- 6 years). When a girl <15 yo gets pregnant for the first time, she has an OR of 2.25 (IC 95%: 1.71-2.95; X2: 35,46; p<0,001) of getting pregnant again during adolescence compared to girls that get pregnant between 15-18 yo. About interventions, the group under 15yo had an OR 2.75 (in Chile all forms of abortions are illegal) compared with the group above 15 years, of requiring surgery when pregnant. Conclusions: The frequency of adolescent pregnancy analized, is above the national and international publications. Plus, if the pregnancy occurs under 15 yo, they have a greater chance of having another teenage pregnancy. An effective secondary prevention could be administration of contraception during immediate postpartum, ideally LARCs.
