ObjectiveTo explore the prevalence situation and risk factors for irritable bowel syndrome (IBS) of students in higher vocational colleges. MethodsThe cluster sampling method was performed to select 2 626 freshmen from a higher vocational college in Guangxi Zhuang Autonomous Region. The students were diagnosed using the Rome IV standard questionnaire to understand the prevalence situation of students with IBS. Logistic regression analysis was performed on risk factors for the prevalence of IBS. ResultsAccording to the Rome IV standard, the total prevalence of freshmen with IBS in higher vocational college was 2.70%, of which the prevalence of IBS in boys was 1.69%, whereas the prevalence of IBS in girls was 3.00%. There was no statistically significant difference in the prevalence of IBS between students with different genders (P＞0.05). There was also no statistically significant difference in the prevalence of IBS between different ethnic freshmen (P＞0.05). Univariate analysis revealed that there was statistically significant difference of comparison between the situation of alcohol consumption in healthy freshmen, a cold catch, dairy intake, fatigue, poor mood and mental stimulation etc., and freshmen patients with IBS (P＜0.05). Multivariate logistic regression analysis exhibited that dairy intake and mental stimulation were independent risk factors for the prevalence of freshmen with IBS in higher vocational college(P＜0.05). ConclusionDiary product consumption and mental stimulation are independent risk factors for the prevalence of freshmen with IBS in higher vocational college. Students face a great academic pressure generally, which increase the prevalence of IBS. It is of great significance to strengthen education of students and awareness of visiting doctors when necessary, find and eliminate the causes of the disease, and thus reduce the prevalence and improve life quality.
