Pattern of Ultra Processed Food (UPF) Consumption and Mental Wellbeing of Medical Undergraduates of Chengalpattu district, Tamil Nadu, India – A Cross sectional Study

Background: Nutrition plays a crucial role in the health and development of individuals. In recent years, the rise in ultra-processed food (UPF) consumption, especially among young adults, has been linked to various health issues, including mental health concerns. This study aims to assess the pattern of UPF consumption and its impact on the mental well-being of medical undergraduates in Chengalpattu district, Tamil Nadu. Methods: A cross-sectional study was conducted among 384 medical undergraduates aged 18 years and above enrolled in three tertiary care teaching hospitals. Data was collected using a questionnaire, which included demographic details, lifestyle factors, a UPF frequency questionnaire, and mental well-being assessments using the Perceived Stress Scale (PSS) and the Patient Health Questionnaire (PHQ-4). Data analysis was performed using SPSS version 29. Results: The study found that 87.2% of participants consumed high amounts of UPFs, with a significant association between higher UPF intake and elevated perceived stress (p=0.026). Participants also reported using UPFs as mood enhancers, particularly during emotional instability. Conclusion: The study highlights the widespread consumption of UPFs among medical undergraduates, which is linked to higher stress levels. These findings emphasize the need for educational interventions to promote healthier eating habits and improve mental well-being among medical students.
