Prevalence and predictors of functional gastrointestinal disorder among the undergraduate students of Bangladesh.

Objective: This study aimed to address this knowledge gap by investigating FGID prevalence and its predictors among undergraduate students in Bangladesh.

Design: This cross-sectional study was conducted between 01 August 2023 and 31 January 2024 among 1,019 undergraduate students. Data were collected using a web-based survey containing questions on socio-demographics, the Rome IV questionnaire, the insomnia severity index, the perceived stress scale 4, the patient health questionnaire, and the smartphone addiction scale. Descriptive statistics, the chi-square test, the t-test, and the multivariable logistic regression model were used to report our study findings.

Results: The overall prevalence of FGID was 38.24%, with functional constipation being the most common subtype (18.24%). The multivariate analysis revealed that college canteen meal (AOR: 1.593, CI: 1.068, 2.376), occasionally and regularly delayed meal (AOR: 1.663, CI: 1.031, 2.682; AOR: 1.872, CI: 1.061, 3.301), physical inactivity (AOR:0.41, CI: 1.061, 3.301), family history of FGID and GI disease (AOR: 4.7, CI: 2.55, 8.66; AOR: 2.42, CI: 1.47, 3.96), history of abdominal surgery (AOR: 2, CI: 1.08, 3.72), psychological trauma (AOR: 1.64, CI: 1.04, 2.57), dairy-product consumption (AOR: 1.64, CI: 1.04, 2.59), >3 meals/day (AOR: 1.89, CI: 1.2, 2.98), insomnia (AOR: 1.98, CI: 0.73, 5.40), and depression (AOR: 7.02, CI: 2.74, 17.98) were significantly associated with FGID.

Conclusion: The burden of FGIDs among Bangladeshi students is concerning. This study found significant factors contributing to their prevalence, including meal source and number of daily meals, delayed meals, family history of disease, physical activity, abdominal surgery, history of psychological trauma, depression, and insomnia. This study recommends further exploration and holistic healthcare approaches to better the well-being of young adults dealing with FGIDs.
