Introduction:

Most pregnancies in adolescents and young adults are unwanted and many are the consequence of inconsistent contraception use.

Objective:

To analyze the risk factors that may influence on female adolescents with unwanted pregnancies.

Method:

Cross-sectional, descriptive study in Ecuadorian female medical students, where the 2013 National Sexual and Reproductive Health Survey, the family APGAR scale, and the Graffar-Méndez Castellanos socio-economic scale were used.

Results:

There was statistically significant difference in the age of active sexual life initiation between those who became pregnant (18.11 ± 1.45) and those who did not (19.22 ± 2.28). Average age at pregnancy was 20.41 ± 2.18; 59.3 % of those who had a pregnancy and 32% of those without pregnancy did not use protection in their first intercourse. Pregnancy was more common in city residents (100%), Catholic females (85.2%), who belonged to middle-high (55.6%) and middle-high socioeconomic strata (29.6%) and to families with moderate dysfunction (40.7%).

Conclusions:

A significant percentage of adolescents in our study had an unwanted pregnancy at an early age despite being young undergraduate medical students, coming from moderately dysfunctional families and belonging to a middle-high socioeconomic status.
