The Association Between Depression and Activity of Inflammatory Bowel Disease

Background: The association between depression and inflammatory bowel disease (IBD) has been reported worldwide. Objectives: We aimed to investigate the prevalence of active and inactive IBD depression and its associated risk factors among patients with depression and IBD. Materials & Methods: In this cross-sectional study, demographic data and clinical characteristics of ۱۵۶ IBD patients referred to Razi Hospital, Rasht City, Iran, were recorded from ۲۰۱۵ to ۲۰۱۶. The Beck depression inventory (BDI) was administered to all patients, and their scores were classified as no, mild, moderate, and severe depression. Modified Truelove and Witts severity index (MTWSI) for ulcerative colitis (UC) and Harvey Bradshaw severity index (HBSI) for Crohn’s disease (CD) were used to quantitate IBD activity as active UC (scored ≥۱۰) and active CD (scored ≥۷). Results: About ۳۵.۹% of the patients (n=۵۶) had depression. Patients with active IBD had significantly higher BDI scores than those with inactive IBD (۱۴.۴۱±۱۰.۳۴ vs ۱۰.۱۴±۱۰.۲۸, respectively, P=۰.۰۱۱). Except for income (P=۰.۰۰۱), no significant associations were detected between IBD status and other background variables (P>۰.۰۵). No patients in either active or inactive IBD groups had cancers. Based on the severity of depression, the patients were grouped as follows: ۶۴.۱% had no depression, ۳۰.۱% had mild depression, ۵.۸% had moderate depression, and ۰.۰% had severe depression. However, significant positive associations were seen between an increase in depression severity and having autoimmune diseases, a lower education level, and a history of IBD-related surgeries. Conclusion: It seems that patients with active IBD are more depressed than inactive IBD patients.
