Background: Teenage pregnancy is a social problem associated with multiple determinants. Colombia has a high rate of teenage pregnancy Objective: To determine risk factors associated with teenage pregnancy in women and develop a predictive scale pregnancy in adolescent girls. Methods: Case-control study with 151 female adolescents aged 19 or younger, pregnant, with children or a history of pregnancy and 302 controls sexually active female adolescents (SA) with no history of pregnancy. Associations were determined by odds ratio (OR). Multivariate analysis was used logistic regression (LR). With the LR variable predictor of pregnancy model was created, evaluating their performance by sensitivity, specificity and area under ROC. Results: Pregnancy was significantly associated with individual variables: not be educated or studying, SA start at 15 or younger and not use methods of family planning (FP) in all sexual intercourse; family variables: maternal education less than high school, adolescent sex education for the mother and FP methods supply by the mother, and socio-cultural variables: belong to the socio-economic stratum 1 and have not received FP education by teachers, health or different to parents. The model had 92.1% sensitivity, specificity 68.9% and area under ROC 0.805. Conclusions: The causes related to pregnancy involve individual, family and socio-cultural factors. Promoting abstinence is a worthwhile goal, especially among younger adolescent, however, the global scientific evidence shows that it is not enough to prevent unwanted pregnancies.
