“…It is unlikely that participants selected by physicians may be biased since physicians were asked to exclude FGID patients who had improved their GI symptoms and the mean severity score in IBS patients was considered as a moderate level at the index visit on the IBS-SSS, 13 which was almost concordant with the previous findings of validation studies for IBS. 9,23,24 Lastly, IBS patients were significantly younger in age compared with FD patients or control subjects. Younger population might be more educated than older population in Japan.…”

Background/AimsReliable diagnostic instruments for measuring the presence of functional gastrointestinal disorders based on the Rome III criteria have been lacking in Japan. The aims of the present study were to translate and validate the Rome III diagnostic questionnaire which was widely used in Western countries. MethodsThe original version of Rome III diagnostic questionnaire was translated from English into Japanese through 3 independent forward translations, resolution, back translation and reconciliation of the differences. Forty-nine patients with irritable bowel syndrome (IBS), 32 patients with functional dyspepsia (FD) and 56 subjects without any current GI symptoms as controls were recruited from three hospitals located in different regions of Japan and completed the IBS and FD diagnostic modules twice within 14 days. Kappa statistic was used to assess test-retest reliability. The sensitivity and specificity of each diagnostic module for distinguishing IBS or FD patients from controls was tested. Olafur Palsson.

ORCID: Motoyori Kanazawa, http://orcid.org/0000-0003-1953-3336. Motoyori Kanazawa, et al Journal of Neurogastroenterology and Motility 538 ResultsMedian kappa statistics were 0.63 for the translated IBS diagnostic module and 0.68 for the FD module. The sensitivity, specificity, and positive predict value of the IBS module against physician diagnosis was 61.2%, 100%, and 100% and those of the FD module was 53.2%, 98.2%, and 94.4%, respectively. Meanwhile, IBS patients were significantly more likely to report blood in stools compared to controls (18.4% vs 1.8%, P ＜ 0.01). ConclusionsThe IBS and FD diagnostic modules on the Japanese version of the Rome III diagnostic questionnaire are valid and reliable. Further studies are warranted to elucidate the diagnostic utility of the red flag questionnaire. (J Neurogastroenterol Motil 2015;21:5...

“…On the other hand, it is lower than that reported in Japan (25.2%) among male nursing and medical school students (Okami et al, 2011). The studies that were conducted in Japan revealed that the prevalence rate was about 5 to 10% (Miwa, 2008;Shinozaki et al, 2006) while the prevalence rate among university students was 10.7% (Shiotani et al, 2006). In Nigeria, the prevalence rate of 26.1% has been reported among medical students (Okeke et al, 2005).…”

Irritable bowel syndrome (IBS) is considered as a prevalent gastrointestinal disorder which ischaracterized by some non-specific symptoms, such as altered bowel habits and abdominal pain. There is no recognized organic pathology associated with IBS. The prevalence of IBS is different in different communities. Its etiology remains uncertain or obscure, perhaps multifactorial. The predestined objective was the determination of prevalence, associated factors and impact of IBS on medical student studying in Prince Sattam bin Abdulaziz University. A cross-sectional study was carried out among male medical students enrolled in Prince Sattam bin Abdulaziz University during the academic year 2013 to 2014. All male medical students of second to sixth year were invited for participation in the study by filling study questionnaire. A validated, reliable, confidential, and self-administered questionnaire was used for data collection. Rome III Criteria was used for the diagnosis of irritable bowed syndrome. The IBS prevalence was 21% with profiles characterized by constipation (20.0%), diarrhea (34.3%), and other alternating symptoms (45.7%). Students who having history of chronic health problems were about three times more prone to develop IBS (OR=2.93). Those reported having stress was at 2.63 times more risk to develop IBS. Those having food hypersensitivity as compared to others were more liable to develop IBS (OR=3.29). IBS was not significantly associated with academic performance. IBS prevailed among medical students. Thus, screening of these students for psychological problems, IBS and stress management strategies are recommended for these students.

“…Subjects were classified into three subgroups as follows: Diarrhea-predominant IBS (IBS-D), constipation-predominant IBS (IBS-C), and alteration type IBS (IBS-A). We used a Japanese version of the Rome II modular questionnaire, including 15 items complied by Shinozaki et al [28].…”

Background: The aim of this study was to verify the efficacy of lifestyle self-monitoring for the improvement of the IBS and reveal what has been changed due to the intervention. Methods: A total of 111 nursing school students were randomized into three groups, two intervention groups (a two-month intervention group, n = 34, and a four-month intervention group, n = 35) and a control group (n = 34). The intervention groups conducted lifestyle self-monitoring in conjunction with a 15-minutes group work for either two or four months. The primary outcome measure was Rome II criteria for IBS. Other outcome measures were the Hospital Anxiety and Depression Scale (HADS) and the Gastrointestinal Symptom Rating Scale (GSRS). They were assessed at the baseline and the end of both of the intervention periods. Analysis was conducted as intention-to-treat. Results: The prevalence of IBS did not change significantly after the intervention in any of the groups. The HAD-A score, a subscale of the HADS score for anxiety, decreased 1.4 points in the two-month intervention group (p = 0.02) and 2.3 points in the four-month intervention group of (p = 0.01) after intervention. The average GSRS decreased 0.2 points in the control group (p = 0.05) and 0.3 points in the four-month intervention group (p < 0.01). Conclusions: Lifestyle self-monitoring for two or four months did not reduce the prevalence of the IBS significantly, but it did decrease anxiety and improved the QOL related to gastrointestinal symptoms in female nursing school students.
