Objective:

To evaluate the association between anxiety disorders and the subsequent diagnosis of irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD).

Key Findings:
  • 1.1% of patients with anxiety developed IBS compared to 0.4% of controls.
  • Anxiety preceded IBD slightly more often than in matched controls, but the absolute incidence was low.
  • 6.6% of patients with IBS developed anxiety compared to 3.0% of controls.
  • The incidence of anxiety in IBD patients was similar to controls at 2.6% and 2.7%, respectively.
Interpretation:

The associations between anxiety and IBS are significantly stronger than those between anxiety and IBD, suggesting a more pronounced bidirectional relationship with IBS.

Limitations:
  • Retrospective observational design limits causal inference.
  • Potential misclassification of diagnoses due to reliance on administrative codes.
  • Inability to assess disease severity or changes in disease activity.
  • Residual confounding from unmeasured factors may persist.
  • Extensive exclusion criteria may limit generalizability.
Conclusion:

The study highlights a significant association between anxiety and IBS, with weaker links to IBD, indicating the need for further research to understand these relationships.
