NCT03995043

Brief Summary

The PREVENT Project is a multifaceted, adolescent friendly, culturally competent program aimed to address the issues surrounding unplanned pregnancies and lack of access and uptake of contraceptive services among adolescent girls. The intervention uses a mobile platform that provides educational SMS (Short Message Service) messaging, interactive voice response, and connects adolescent girls to community based AFSRH (Adolescent Friendly Sexual Reproductive Health) counselling services, as well as discreet contraceptive access points headed by female entrepreneurs. The program will be piloted for 12 months in various wards and villages in rural and urban Kilimanjaro, Tanzania.The acceptability and practicality of the intervention will be assessed using mixed methods. Questionnaires and focus groups will be conducted with the study participants, as well as the medical and non-medical volunteers at the start and end of the pilot. The study will be heavily supported by all-female non-medical social entrepreneurs and sexual reproductive health community mentors (volunteers), and, all-female medical reproductive health team. Recruitment will also take place in hair saloons (local hair braiding and styling establishments) and other female run business such as tailors and female clothing stores that have enlisted to become contraceptive access points in the study. There will be 2 intervention groups, control and case group. Both groups will receive educational SMS (text) messages on SRH (Sexual Reproductive Health) and access individually tailored educational resources through interactive voice response (IVR) services/system via PREVENT mobile platform. In addition to personal support to be able to contact with a SRH community peer mentor in the community for AFSRH counselling and support. The case group will then have access to contraception provided with detailed and discreet information on accessing PREVENT contraceptive access points in all communities included in the study.
