Interventions to Increase Adherence to a Gluten Free Diet in Patients with Coeliac Disease: A Scoping Review

Coeliac disease is a chronic inflammatory disorder of the small bowel, characterised by permanent intolerance to gluten. The only current and effective treatment for coeliac disease is a gluten free diet [GFD], however this is challenging for patients to adhere to. The review aims to identify published interventions designed to improve patients' adherence to a GFD. Ten intervention studies were identified and included within the review; whilst heterogeneous in delivery, all included an educational, behavioural, and practical element. Five interventions significantly improved dietary adherence, these included follow-up appointments, a telephone clinic, an online course, cooking sessions and psychological support. All studies were small and used varied methods to assess adherence. There is a paucity of well-designed interventions to promote dietary adherence, in future more robust methods for ascertaining adherence is needed, we recommend greater inclusion of dietetic assessment and combining more than one method for assessing adherence.
