Continuing high rates of adolescent childbearing in sub-Saharan Africa indicate a need for improved understanding of factors affecting adolescent sexuality. As traditional cultural influences on adolescent sexuality in Africa have diminished, peer interaction and modern influences have gained importance. To study peer interaction and societal factors and their impact on adolescent attitudes toward sexuality and contraception, the authors conducted a series of single-sex-focus-group discussions with in-school and out-of-school youth in urban and rural areas of Kenya and Nigeria in 1990. Out-of-school youth generally receive information on sexuality and family planning from peers (and the media), while in-school youth receive information in school, although not necessarily relevant information. Young women interviewed perceived unwanted early childbearing as something that affected them, an important precursor to family planning use. However, young people tended to have better information and more positive attitudes about induced abortion than about family planning.
