This paper analyses the issue of adolescents' access to family planning services and information on reproductive health. The data used in this paper are a part of a broader study conducted in 1995 in Dakar (Senegal) by the Committee for Studies on Women, Family and Environment in Africa (COSWFEVA/CEFFEVA) and Family Health International. The findings present information on adolescents' perceptions of premarital sexual activity and contraceptive use and the different types of barriers to access to family planning, using data obtained primarily from focus group discussions with adolescents 16 to 20 years old and a mystery client study. In this approach, 12 of the adolescents participating in the focus group discussions visited clinics as clients and requested contraceptive methods or information. The results indicate that adolescents did not approve of premarital sexual relations, were less likely to approve of contraceptive use by adolescents than by married men and women, and felt embarrassed to go to the services. They were also disappointed by the providers' reception and response to their needs. The content of the counselling offered by the providers was moralistic, encouraging girls to abstain from having sexual intercourse until marriage. The discussions of the findings related adolescents' and providers' attitudes to the socio-cultural context in which adolescent sexuality takes place. In this context, sexuality is closely linked to marriage and childbearing, which affects the impact of classical programs on adolescent health. Alternative solutions such as the life skills development approach could be promoted in order to reach both in-school and out-of-school adolescents.
