Abstract Early pregnancies are often linked to precarious situations. Even if Belgium has seen a decrease in teenage pregnancies, in the former mining region of the Hainaut there are still twice as many births to young women under 20 compared to the national rate. Colfontaine is one of the poorest cities in Belgium. Last year, one of the local high schools counted 10 pregnant teenagers out of 450 students. Médecins du Monde was already present in the city at the time with a mobile health clinic called the Médibus. In response, we carried out a mapping of the local sexual and reproductive health actors. The lack of accessibility to social and health structures capable of welcoming teenagers anonymously and free of charge quickly emerged as a problem, the nearest family planning center being located 30 minutes away by bus. In September 2019, in partnership with 5 local health actors, we decided to reshape the Médibus into the Adobus in order to offer family planning consultations, health promotion and harm reduction activities at the high school once a week. In addition to offering health information services, we also aim to detect teenagers experiencing vulnerable situations such as addiction, violence, gender issues and refer them to appropriate services. Halfway through the project, we met 430 teenagers in 14 afternoons. The most common reasons for consultation (N = 310) were questions related to contraception for 29% and to sexually transmitted infections for 24,5%. 70,9% of teenagers received condoms and 13 girls were tested for pregnancy. One girl received a morning-after pill. 3 teenagers with addiction problems and 17 victims of violence were detected. The teams referred 18 teenagers to other services. The success of this outreach project confirms the need for information regarding sexual and reproductive health for teenagers living in precarious situations as well as the need to develop reachable and affordable sexual and reproductive health services in semi-rural areas.
