Are there specific risk factors for irritable bowel syndrome in Bangladeshi students?
Irritable bowel syndrome (IBS) is a common gut-brain disorder that causes abdominal pain and changes in bowel habits. For Bangladeshi university students, a recent reanalysis of data from 506 students identified specific risk factors that may be more relevant than previously thought. The strongest predictors were psychological distress, higher body mass index (BMI), and academic dissatisfaction. These findings suggest that mental health and lifestyle factors play a key role in IBS among this population.
What the research says
A 2025 reanalysis of a dataset of 550 Bangladeshi students (reduced to 506 after removing implausible records) used a machine-learning method called Explainable Boosting Machines to identify the strongest predictors of IBS 6. The model found that psychological distress, elevated BMI, and academic dissatisfaction were the top risk factors, with an average accuracy (AUC) of 0.852 6. This means the model correctly distinguished students with IBS from those without about 85% of the time. Notably, the study found that physical activity showed a non-linear risk pattern only at high intensity, and the link between gender and IBS was much weaker when accounting for metabolic and psychological factors 6. These results differ from the original logistic regression analysis, likely because the machine-learning model captured complex interactions that simpler methods miss 6. Globally, psychological stress is a well-established trigger for IBS, affecting gut sensitivity, motility, and the gut-brain axis 8. Diet also plays a role, with low-FODMAP diets showing efficacy, though restrictive diets can be challenging 9. The global prevalence of IBS is about 11.2%, with higher rates in women and younger adults 10.
What to ask your doctor
- Could my IBS symptoms be related to stress, anxiety, or academic pressure?
- What role does my diet play, and should I consider a low-FODMAP diet?
- How can I manage my weight or BMI to potentially improve IBS symptoms?
- Are there any mental health resources or counseling services available for students?
- Should I track my symptoms and possible triggers in a diary?
