AIM:To estimate the prevalence of irritable bowel syndrome(IBS)in college and university students of North China and certain related factors for IBS.METHODS:A total of 2500 students from Shandong University in North China were asked in February-March 2009 to complete questionnaires,including the Rome Ⅲquestionnaire,hospital anxiety and depression scale,and IBS-quality of life questionnaire(IBS-QOL).RESULTS:Among the 2126 students with complete data,the prevalence of IBS was 7.85%according to the RomeⅢcriteria,with a female/male ratio of 1.78:1.Most students had the IBS-constipation subtype (36.5%),followed by IBS-diarrhea subtype(31.1%)and IBS-mixed subtype(23.9%).The students with IBS had a higher anxiety and depression score than those without IBS.Low exercise level and anxiety indicated a high risk for IBS.The mean score of IBS patients was 74.2± 4.242 on the IBS-QOL.CONCLUSION:The prevalence of IBS is 7.85%in Chinese college and university students according to the RomeⅢcriteria.Low exercise level and anxiety may be the risk factors for IBS.
