BAUTISTA CERECEDO, Ranulfo; ORTIZ ESPINOSA, Rosa María  and  MUNOZ JUAREZ, Sergio. Irritable bowel syndrome in medical students. Rev. Fac. Med. (Méx.) [online]. 2011, vol.54, n.3, pp.4-11. ISSN 2448-4865.

Objective: To estimate the prevalence of IBS in medical students and calculate both its association with anxiety, depression and stress, and its impact on students' academic performance. Material and methods: Resea rch design: a compa rative, analytical cross-sectional study. Probabilistic multistage sampling for the selection of students regardless of age and sex was used. Clinical history, anxiety record, Beck depression inventory, life event records and the academic record were used as data sources. Results: 219 students were chosen; 58% of them were women in which the prevalence of IBS was 24.7. The prevalence of anxiety was 94%, depression 38% and stress 60%. Women were the most affected (P<0.05). The grade point average of student who suffered from IBS was 8.25+0.37 and the average of failed subjects was 2.68+2.26 (P>0.05). Stress was associated with IBS OR=6.6 with IC95% 3.2-13.7; anxiety OR=38.6 with IC95% 11.4-199.2; and depression OR=49 with IC95% 2.2-11.1. Conclusions: IBS is associated with anxiety, depression and stress. Meaningful differences were found between women and men. IBS does not affect the students' academic performance.
