Background: With the unprecedented pace of modernization, risky sexual behaviors have become more frequent in developing countries, such as Iran. We aimed to assess the prevalence of informal sexual relationship (ISR) and factors associated with having ISR in young adult in Iran.
Methods: This cross-sectional study was conducted on 414 young adult smartphone users in Iran, in 2019. Data was collected through an online questionnaire (including: ISR, socio-demographic variables, their use of social network, religious beliefs, personality, and loneliness). Logistic regression model was used to determine factors related to ISR.
Results: A total of 152 (36.7%; 95% CI 32.1-45.6) participants reported having ISR. Finding an opposite-sex friend through a mobile app (OR = 2.59, 95% CI 1.34, 5.01), being currently sexually active (OR = 2.39, 95% CI 1.26, 4.56), higher scores of extroverted personality (OR = 1.13, 95% CI 1.01, 1.27), and closer relationship with parents (OR = 3.17, 95% CI 2.25, 8.02) were found to be associated with having ISR. Additionally, living in small cities rather than the provincial capital (OR = 0.23, 95% CI 0.10, 0.49) had a reverse association with having ISR.
Conclusions: This study illustrated the high prevalence of ISR and its association with increased duration of internet and mobile app use. Innovative and multidisciplinary approaches could be recommended in this regard.
