Mobile social networks (MSNs) have emerged as a pervasive technological phenomenon in the 21st century, significantly influencing both mental health and social interaction. This study aims to determine the relationship between MSN use and mental health as well as social behaviours among medical students. This demographic is particularly salient due to their increasing engagement with MSNs and their crucial role as prospective contributors to societal health and development. A cross-sectional study was conducted involving 260 medical students enrolled at a university in southern Iran. Data were collected using the 28-item General Health Questionnaire (GHQ-28), a purpose-designed questionnaire assessing mobile social network addiction, and a social behavior questionnaire. Statistical analyses were performed using SPSS version 22. The findings indicated that approximately 30% of the student population exhibited behaviors suggestive of emerging social media addiction. A statistically significant positive correlation was found between the extent of social network use and mental health status (r = 0.242, p = 0.001). Furthermore, a significant relationship was observed between the use of mobile social networks and social behaviors (r = 0.138, p = 0.036). Mobile social network use is widespread among medical students in southern Iran. The findings suggest an association between MSN and psychological disturbances, including anxiety, sleep disorder, and depression, as well as reduced social maturity. It is crucial to note that these findings highlight potential correlations rather than causal relationships, as the cross-sectional design does not allow for causal inferences. Educational programs and psychological interventions promoting balanced social media use may help support students' mental health and social development.
