Pediatric-to-adult Transition and Medication Adherence in Patients with Inflammatory Bowel Disease.

Background: Medication nonadherence is common in inflammatory bowel disease and is associated with poor outcomes. There has been no study on pediatric-to-adult transition as a risk factor for nonadherence in inflammatory bowel disease, which has been demonstrated in other diseases. We aimed to assess whether transitioned (TR) patients have higher nonadherence rates than young adults (YAs) diagnosed in adulthood.
