Conclusion
This study has identified risks and risk sexual behaviors for STIs and/or HIV infection on university students. The knowledge of the students towards STIs and/or HIV is unsatisfactory. More than half of the students were at risk for STIs and/or HIV infection. Casual/benefit based sexual relationship with first sexual partner and having multiple sexual partners (≥4 sexual partners) in the last 12 months were independent predictors of STIs and/or HIV infections. Therefore, university based, risk reduction and behavior change focused interventions are recommended.
