Background:
Functional bowel disorder (FBD) is conceptualized as a "biopsychosocial disorder." Psychological factors are important moderators of symptom severity and persistence, treatment seeking and response to treatment. We investigated psychological factors and quality of life (QOL) in patients with FBD.
Methods:
Seventy patients visiting the department of medical gastroenterology diagnosed as FBD were included in the study. Severity of FBD was rated with FBD Severity Index. The Depression, Anxiety, and Stress Scale was applied and patients were divided into two groups, i.e., with moderate stress (Group A) and with severe stress (Group B). QOL in both the groups was assessed by WHOQOL-BREF Scale. Chi-square, t-test was done to compare the groups. Regression analysis was done to find predictors of poor QOL. P < 0.05 was taken as significant.
Results:
Patients of Group B had a longer duration of illness and had higher prevalence of depressive disorder (P = 0.03) in comparison to patients in Group A, who had higher prevalence of anxiety disorders (P = 0.06). Severity of FBD was positively correlated with depression (r = 0.8; P = 0.02). Physical and psychological QOL was significantly impaired in Group B patients having depression (P = 0.02; P = 0.03). Regression analysis showed a positive trend for presence of depressive disorder (P = 0.05), anxiety disorder (P = 0.08) and severity of FBD (P = 0.09) as predictors of poor QOL.
Conclusion:
In our study, the high prevalence of stress, anxiety and depression in patients with FBD indicates the need for routine screening of such symptoms along with a collaborative and holistic treatment approach. Several etiological perspectives explaining the complex gut-brain interaction are also provided.
