Irritable bowel syndrome-related symptoms among medical students in Bosnia and Herzegovina.

AIM: To determine the prevalence of irritable bowel syndrome (IBS)-related symptoms and associated factors among medical students in Bosnia and Herzegovina. METHODS: This cross-sectional online survey included 176 medical students from the universities of Sarajevo and Zenica between November 2022 and December 2023. IBS-related symptoms were assessed using the Serbian-language Rome III questionnaire, and test anxiety using the Westside Test Anxiety Scale. Categorical variables were compared using Pearson's χ² test. RESULTS: Eighty-four students (47.7%) met the symptom-based Rome III criteria. The IBS-related symptoms group included 75 females (89.3%) compared with 54 (58.7%) in the comparison group (p<0.001). Sweets consumption at least four times weekly was reported by 53 (63.1%) and 45 (48.9%) students, respectively (p = 0.021). Test-anxiety distributions differed between groups (p < 0.001); extremely high anxiety was reported by 12 (14.3%) students with IBS-related symptoms and one (1.1%) without symptoms. Other sociodemographic and lifestyle characteristics were not associated with IBS-related symptoms. CONCLUSION: IBS-related symptoms were frequent in this medical-student sample and were associated with female sex, frequent sweets consumption, and test anxiety. The cross-sectional, self-reported design precludes causal interpretation and clinical confirmation of IBS.
