Abstract
Introduction: Irritable bowel syndrome (IBS) is often associated with psychiatric disorders such as obsessive-compulsive disorder (OCD). This meta-analysis was conducted to compare the rate of OCD among patients with IBS and a control group.
Methods: This study was conducted using a meta-analysis approach. International databases including PubMed, Web of Science, and Scopus, as well as the Google Scholar search engine from 1985 to August 2020 were searched to find the related studies. The standardized mean difference (SMD) of OCD between the case and control groups was calculated and analyzed by a random-effects model. In addition, meta-regression and sub-group analysis were performed to identify possible causes of heterogeneity. All statistical analyses were performed through Stata 11.0.
Results: A total of 5167 patients including 1451 IBS patients for case and 3716 for control group collected from 15 studies entered the analysis. Based on the results of the random effects analysis, the rate of obsessive-compulsive disorder in IBS patients in case group was higher than the control group (Pooled SMD, 0.76, I2 = 87.8%; 95% CI, 0.54-0.98; P <0.001). Egger (P = 0.083) and Begg (P = 0.09) tests did not show significant publication bias. Subgroup analysis also revealed that the type of studies and IBS diagnostic criteria were identified as factors affecting heterogeneity.
Conclusion: The present meta-analysis demonstrated that the rate of obsessive-compulsive disorder in IBS patients was higher than the control group, regardless of subgroup analysis or meta-regression. Due to the significant relationship between these two disorders, psychiatrists and gastroenterologists can provide strategies and techniques for individual or group treatment of obsessive-compulsive disorder in patients with IBS based on the cognitive-behavioral therapy.
