Abstract: Background: Obesity is a global health issue, with a prevalence of 13.1% worldwide and 3.9% in India (WHO, 2020). Among Indian medical students, increasing rates of obesity are linked to stressful education, lack of physical activity, and irregular diets. Studies show obesity impairs cognitive functions, including executive function and memory. This study investigated the relationship between Body Mass Index (BMI) and cognitive function in medical students, with a focus on gender differences. Method: This cross-sectional study included 212 GMCH medical students selected via random sampling. BMI was measured using digital weight and height scales, and cognitive function was assessed with the 30-item Mini-Mental State Examination (MMSE). Data analysis utilized SPSS software, employing p-value, Pearson?s correlation coefficient to evaluate the BMI-cognitive function relationship. Results: A significant correlation was found between higher BMI and lower cognitive function scores, with gender differences observed. These findings highlight the need for weight management strategies to enhance cognitive health in students. Conclusion: This study contributes to the understanding of how obesity impacts cognitive function in medical students, emphasizing the importance of addressing obesity to preserve cognitive health.
