Objective:
To investigate the relationship between irritable bowel syndrome (IBS) and overactive bladder (OAB) in men and women using questionnaires.
Materials And Methods:
This research survey was based on multicenter data (men and women older than 20 years). The Korean version of the Rome III criteria was used for the diagnosis of IBS, Overactive Bladder Symptom Score (OABSS) was used for screening OAB, Self-Rating Depression Scale was used for depressive symptoms, and International Prostate Symptom Score and Quality of Life were used to determine the degrees of lower urinary tract symptoms.
Results:
A total of 609 (men: 257, women: 352) people answered the questionnaire. The prevalence of IBS and OAB was 31.9% (men vs women: 27.3% vs 39.2%) and 19.2% (men vs women: 25.3% vs 18.5%), respectively. The OABSS values of patients with IBS and non-IBS patients were 1.70 ± 2.48 and 2.48 ± 2.79 (P <.001). On the Self-Rating Depression Scale, individuals with IBS had a higher score than non-IBS individuals (n = 201) (44.92 ± 13.71 vs 39.19 ± 10.39, P <.001). In men, non-IBS (n = 56) had higher OABSS and OABSS question number 3 responses than patients with IBS (OABSS: 2.56 ± 2.69 vs 1.57 ± 2.43, P = .01, OABSS Q3: 0.92 ± 1.26 vs 0.66 ± 1.13, P = .17). Also, in women, non-IBS (n = 214) had higher OABSS and OABSS question number 3 responses than patients with IBS (n = 138) (OABSS: 2.40 ± 2.87 vs 1.76 ± 2.52, P = .03, OABSS Q3: 0.83 ± 1.25 vs 0.70 ± 1.18, P = .32).
Conclusion:
IBS in adults had no relationship with OAB in our study. These data suggest that more studies are needed to determine the relationship between IBS and OAB.
