Sexual behavior and risk of HIV/AIDS among adolescents in public secondary schools in Osogbo, Osun State, Nigeria.

Unlabelled: Young people are particularly vulnerable to unplanned sexual activities. This study sought to identify the sexual behaviors and risk of HIV among public secondary schools students in Nigeria.

Methods: A cross-sectional survey of 521 students in eight randomly selected public secondary schools. Respondents were selected by a multistage sampling technique from amongst the study population. Using a self-administered, semi-structured, pre-tested questionnaire, data were obtained concerning their sexual behaviors and influencing factors.

Results: Most respondents (n = 387, 74.3%) were in late adolescence. Many knew the consequences of premarital sex as unplanned pregnancy, STI/HIV/AIDS, incomplete schooling, and guilt feelings. About 40% of the respondents had been involved in sexual activities with partners who were classmates, neighbors, 'sugar daddies', teachers, or strangers (party-mates or prostitutes). Heterosexual, oral, and anal forms of sex were practiced respectively by 78.1%, 13.3%, and 12.4% of those who were sexually active. Sexual debut was 15.2 +/- 1.62 years. About 36% of those sexually active had more than one partner, and about 14.8% were aware that their partners had other partners. Only 8.6% used a condom on a consistent basis, whereas 41.9% had never used a condom at all. More than half the sexual activities were not pre-planned. The reasons given for engaging in such practices were peer influence, financial reward, drug influence, fun, or experimentation.

Conclusions: Despite their 'above average' level of knowledge of the consequences, the students were still involved in risky sexual behaviors. Behavioral change communications should be intensified among these adolescents.
