HIV/STI RISK-TAKING SEXUAL BEHAVIOURS AND RISK PERCEPTION AMONG MALE UNIVERSITY STUDENTS IN TEHRAN: IMPLICATIONS FOR HIV PREVENTION AMONG YOUTH.

Recent evidence indicates a rising trend in premarital sexual activity among young people in Iran. However, little is known about the extent to which young people's sexual behaviours expose them to HIV and STI risks. This study aimed to assess HIV/STI-related sexual risk-taking behaviours (correlates and determinants) and HIV/STI risk perception among male university students in Tehran.
