BACKGROUND AND PURPOSE: Cognition is the mental action on the process of acknowledge and understanding through thought, experience, and sense. A glowing body of literature is binding that being overweight (OW) or obese (O) has an effect on cognition as well as on physical functioning. A better understanding of this relationship could help target psychological services and public health strategies more effectively. The aim of the present study was to find out the impact of body mass index (BMI) on cognitive function among young adults. MATERIALS AND METHODS: A convenient sample of 300 participants aged between 18 and 24 years was selected for the study. Demographic data and anthropometric measurements were taken. After that, BMI was calculated for all participants and participants were divided into two groups: Group A (normal BMI, n = 150) and Group B (OW/O, n = 130). Twenty students were excluded from the study because of their underweight. Rest of the participants (n = 280) were asked to performed Rey Verbal Auditory Learning test (RVALT), Stroop test, and Trail Making test A and B. STATISTICAL ANALYSIS: Unpaired t-test was used to find out a significant difference in cognitive functions among two groups. RESULTS: It was found that cognition score (all three tests) obtained by normal BMI group was higher than score obtained by OW/O group (RVALT: P<0.0001, Stroop test: P<0.0001, Trail Making Test: Part A: P < 0.04 and for Part B: P < 0.0001). CONCLUSION: The present study concluded that high BMI individuals have lower cognitive functions.
