Objectives: Overweight and obesity has an adverse effect on public health, and emerging adulthood (18-25 years) is recognized as a potential period for the onset of obesity, thus, this study aimed to explore risk factors associated with overweight and obesity in Bangladeshi university students. Participants: Bangladeshi university students (n = 280). Methods: A case-control study of 140 students with overweight and obesity and 140 students with normal weight. Results: Multiple logistic regression revealed having at least one overweight or obese parent (AOR = 4.2; 95% CI: 2.2-8.4) and participating in no physical activity (AOR = 3.2; 95% CI: 1.0-9.9) were potential risk factors. Reported consumption [greater than or equal to]4 meals in a day, junk food/fast food, and soft drinks for [greater than or equal to]3 days a week were potential determinants of overweight and obesity in this population. Conclusion: Increased awareness on the importance of regular physical activity and a healthy diet may reduce the risk of overweight and obesity among Bangladeshi university students.
