The widespread use of smartphones has become an integral part of daily life among medical students, raising concerns about problematic use and its potential impact on health-related behaviours, including eating patterns. Intuitive eating, which emphasizes awareness of internal hunger and satiety cues rather than external influences, has gained attention as a positive approach to eating behaviour and overall well-being.The aim of this cross-sectional study is to assess smartphone addiction risk and intuitive eating behaviours among medical students and to investigate their association with sociodemographic characteristics.524 participants from Istanbul University – Cerrahpaşa Faculty of Medicine 1st, 2nd and 3rd year students were included in our study. Sociodemographic Data Form, Intuitive Eating Scale – 2 and Smartphone Addiction Scale – Short Form scales were applied to the participants face-to-face.Among all participants, 51,7% were found to be at risk of smartphone addiction. There was a negative correlation between Smartphone Addiction Scale score and Intuitive Eating Scale score. Participants with a chronic disease had a significantly higher risk of having smartphone addiction.In the present study, smartphone addiction was negatively correlated with intuitive eating behaviours, indicating that higher levels of problematic smartphone use are associated with lower intuitive eating scores among medical students. This finding is consistent with previous research demonstrating similar patterns in related contexts, suggesting that behavioural addictions can interfere with adaptive eating attitudes and behaviours.In conclusion, this study highlights a significant negative association between smartphone addiction and intuitive eating behaviours among medical students, emphasizing the potential impact of problematic smartphone use on healthy eating practices.
