RESUMEN
ANTECEDENTES: Preferencias personales y prioridades son factores importantes a considerar cuando se elige un método anticonceptivo, y son aspectos claves en la toma de decisiones de la población adolescente. OBJETIVO: Identificar los factores más relevantes al seleccionar un método anticonceptivo y sus razones para elegir o rechazar cada uno de los métodos anticonceptivos disponibles en adolescentes. MATERIAL Y MÉTODOS: Estudio transversal analítico. Un cuestionario anónimo y auto-administrado se aplicó a 116 adolescentes que consultaron durante un año a un centro de salud sexual y reproductiva. RESULTADOS: El inyectable fue el método que más conocen y que más usan, seguido de la píldora. La eficacia, protección contra ITS y regular los períodos menstruales son las tres más importantes razones para elegir un MAC. Mientras que las razones más importantes para no elegir la píldora fue tener que recordar su uso cada día. En el caso del implante, el miedo y dolor al colocarlo y removerlo fue la razón más importante. CONCLUSIÓN: A pesar que la confiabilidad y uso de larga duración pueden ser muy importantes ventajas para posponer embarazo en adolescentes, el miedo al dolor e inserción hacen que los métodos de larga duración como el implante y dispositivos intrauterinos sean menos atractivos para adolescentes.
BACKGROUND: Personal preferences and priorities are important factors to consider when choosing a contraceptive method, key aspects in the decision making of the adolescent population. OBJECTIVE: To identify the most relevant factors when selecting a contraceptive method and its reasons for choosing or rejecting each of the contraceptive methods available in adolescents. MATERIAL AND METHODS: Analytical cross-sectional study. An anonymous and self-administered questionnaire was administered to 116 adolescents who consulted for a year in a sexual and reproductive health center. RESULTS: The injectable method was the most known and most used followed by the pill. Efficacy, protection against STIs and regulation of menstrual bleeding are the three most important reasons for choosing a MAC. While the most important reasons for not choosing the pill was to have to remember its use every day, in the case of the implant, it was the fear and pain to place it and removed it. CONCLUSIONS: Although reliability and long-term use may be very important advantages in postponing pregnancy in adolescents, fear of pain and insertion make long-lasting methods such as implant and intrauterine devices less attractive for adolescents.

STUDY OBJECTIVE: To compare in a regular non-clinical trial experience the efficacy, acceptability, and continuation rates of an injectable contraceptive containing 50 mg norethisterone enanthate plus 5mg estradiol valerate (IC) and an oral contraceptive containing 0.15 mg levonorgestrel plus 0.03 mg ethinyl estradiol (OC), among adolescent users. DESIGN: A total of 251 adolescents ages 14-19 were followed during 12 months. The IC group (124 subjects) was studied for 1044 cycles and the OC group (127 subjects) was studied for 1368 cycles. The users were not assigned in a random selection. Information was collected from clinical records. Groups were compared using Pearson chi-square, odds ratio (95% confidence interval), t-test, and proportion difference test. RESULTS: The IC group had significant differences in baseline social risk, confidence, psychiatric problems, consumption of alcohol, and number of sexual partners. At 12 months, the IC group showed significant decrease in weight and increase in hypermenorrhea. In the OC group, dysmenorrhea decreased, and hypomenorrhea and regular cycles were significantly more frequent. One pregnancy occurred in the OC group (Pearl Index: 0.88). Final continuation rates at 12 months were 41.9% and 37.8% for IC and OC, respectively. CONCLUSIONS: The monthly injectable is a recommended contraceptive option for adolescents, especially for those facing psychosocial risk factors.
