Journal of Adolescence 1996, 19, 179–181 Brief Report AIDS-related knowledge, attitude and behaviour among selected adolescents in N igeria M ARGARET O LABISI ARAOYE AND ALFRED ADEGOKE Introduction The occurrence of AIDS in Africa represents an epidemic with serious economic, social and demographic consequences. It poses a great challenge to Public Health. Behavioural changes are important for AIDS control and well-targeted programmes are essential. Adolescents constitute a high-risk group for HIV infection. The few previous adolescent studies in Nigeria were not specific for in-school adolescents (Feyisetan and Pebley, 1989; Makinwa-Adebusoye, 1992). Although enrolment in secondary school is low; 24% and 17%, respectively, of male and female adolescents aged 10–24 years (Yanagishita and Haub, 1994), it is hoped that this study which was an assessment of the knowledge, attitude and behaviour related to AIDS, will provide some sort of baseline data for the design and implementation of an AIDS prevention programme targeted at in-school adolescents in Africa.  1996 The Association for Professionals in Services for Adolescents M ethods The study was based in Ilorin, the capital of Kwara State, Nigeria. The people are heterogenous, the major ethnic group being the Yorubas. A sample of 1000 students was selected based on the social cluster and the school type (mixed, “all boys” and “all girls”). Within high, medium and low socio-economic clusters, schools were stratified by type. Using proportionate sampling technique, two secondary schools were selected from the high, three from the medium and five from the low socio-economic clusters. Proportionate sampling technique was used to determine the sample size within each school. Approximately, equal numbers of students were then selected, using systematic random sampling technique within sex, from each level in the school. The data were collected in May 1992 by self-administration of pre-coded questionnaire. Records of 30 students were discarded because they fell outside the defined ages (10–19 years). Univariate, bivariate and multivariate analyses were performed using SPSS computer program. Reprint requests and correspondence should be addressed to M.O.
