Abstract: Irritable bowel syndrome (IBS) is among the most common gastrointestinal disorders and is responsible for up to 30-50% visit to gastroenterology clinics. Diagnosis is based on a symptom criteria as the condition has a poorly defined structural basis. The aim of the study was to determine the prevalence of IBS in a student population and compare the agreement between two of these diagnostic criteria. This was a cross-sectional study of clinical medical students at the Nnamdi Azikiwe University, Teaching Hospital, Nnewi. The IBS questionnaire for health care practitioners developed by the world gastroenterology organization (WGO) for the diagnosis of IBS was completed by the students. A total of 228 clinical medical students completed the IBS questionnaire. They were 136(59.6%) males and 92(40.4%) females. Their age ranged from 18-32years with a mean age of 24.03±2.8years. According to the WGO criteria, none had definite IBS, 42(18.4%) subjects had probable IBS and 186(81.6%) subjects do not have IBS. Using the Rome III criteria, the prevalence of IBS among the study population was 30(13.2%). The prevalence was slightly lower in males than in females, 15/136(11%) vs 15/92 (16.3%) but the difference was not statistically significant (p=0.25). cohen’s kappa was 0.18 which shows poor agreement between the WGO and Rome III criteria and it was statistically significant (p=006). IBS is prevalence in our study population. There is poor agreement between the WGO questionnaire and Rome III criteria in the diagnosis of IBS.
