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