Context: About one third of all new HIV infections are estimated to occur among young people globally. In recent years, the increasing age of marriage in Iran has caused increasing risky behaviors in the young population. According to evidence, risk perception toward acquiring HIV is an important factor for risky behaviors. Objectives: This study was conducted to detect the concern toward HIV acquisition among Iranian youths. Evidence Acquisition: In this systematic review, the knowledge, attitudes, threat perception, and practices of youths toward HIV/AIDS were assessed through searching such databases as the Web of Science, PubMed, and Scopus. Quality assessment was done using STROBE and PRISMA-P checklists. A total of 1,036 articles were initially found, of which 28 articles were analyzed. Results: The youths’ knowledge about HIV/AIDS varied from low to moderate, their attitude was generally negative, perceived risk susceptibility was low, and risk perception ranged from 6.5 to 60%. Premarital sexual relationships were reported by 8 - 50% of the youths, while the rate of both condom use and consistent condom use was less than 50%. Conclusions: The current situation is worrisome and needs serious practical measurements. Therefore, urgent and multifactorial interventions such as establishment of youths’ sexual reproductive health services and its integration into the current primary health care system across the country are needed.
