The Prevalence of Irritable Bowel Syndrome and Its Co-existence With Migraine in Medical and Non-medical Students at Al-Baha University, Saudi Arabia.

Abstract

It was hypothesized that the prevalence of irritable bowel syndrome (IBS) and migraine and their co-existence are higher among medical students. In this study, we aim to establish the prevalence of IBS and migraine in the medical and non-medical students at Al-Baha University, Saudi Arabia, and to observe the association and relationship between IBS and migraine using the Rome IV diagnostic criteria for IBS and the International Classification of Headache Disorders (ICHD)-3 criteria for migraine. This cross-sectional study was done on the Saudi Arabian campus of Al-Baha University between July 2022 and July 2023. Al-Baha city-dwelling male and female college students aged 18 to 29 comprised the study population. A self-administered electronic questionnaire was sent online to determine the prevalence of IBSand migraine, in addition to associated risk factors. The questionnaire consisted of three sections: demographic and lifestyle data, the Rome IV criteria for diagnosing and subclassifying IBS, and the ICHD-3 criteria for diagnosing migraine. The study was conducted among 452 participants with a mean age of 21.64 years. The majority of participants were not from medical schools. The majority of medical and non-medical participants were male, at 66.6% and 63.1%, respectively. In our study, 36.9% of the individuals reported having a first-degree relative diagnosed with IBS, whereas 2.7% reported having IBS themselves. Regarding migraine, 17.9% of respondents claimed to have a first-degree relative with migraine, while 6.9% of respondents themselves reported experiencing migraine. Regarding IBS prevalence, there was no significant difference between participants from non-MBBS colleges and MBBS colleges. Similarly, there was no significant difference in migraine prevalence between these two groups (92.0% vs. 95.4%, p=0.185). The current study contributes significantly to our understanding of the prevalence of IBS and migraines among medical students, as well as these individuals' demographic characteristics, familial histories, and aggravating variables.
