Background:
Studies have found that depression is more frequent in patients with inflammatory bowel disease (IBD) than the general population. Clinicians are now trying to pinpoint risk factors for psychological impairment in the IBD population.
Aims:
To examine the demographic and phenotypic variables associated with the development of depression among a diverse cohort of IBD patients. We also sought to describe psychotropic therapy prescribed to IBD patients.
Methods:
We conducted a retrospective cohort study including patients with Crohn's disease (CD) and ulcerative colitis (UC) without a prior psychiatric diagnosis and followed in the gastroenterology clinics of the private university hospital and public safety net hospital at a large academic centre in Miami (Florida). Predictive variables included demographic characteristics, IBD phenotype, exposure to IBD medications, history of a surgical stoma or seton placement, extra-intestinal manifestations, laboratory indices, aggressive disease and disease activity (based on imaging and endoscopic parameters). Proportional hazard regression models and stepwise Cox regression analysis were used for statistical analysis.
Results:
Independent predictors of depression were female gender [HR: 1.3 (95% CI: 1.1-1.7), P = 0.01], aggressive disease [HR: 1.4 (95% CI: 1.02-1.9), P = 0.03] and active disease [HR: 1.5 (95% CI: 1.1-2.0), P = 0.04]. In the group that did develop a depressive disorder, 65% received pharmacologic therapy with one or more psychotropic agents.
Conclusions:
We found female gender, aggressive disease and increased endoscopic/radiological activity to be independently associated with the development of depression in inflammatory bowel disease.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
