Text Message Intervention to Improve Adherence in Adolescents and Young Adults With Celiac Disease

This is a prospective randomized controlled trial investigating the impact of educational bidirectional text message reminders on gluten free diet adherence among adolescents and young adults with celiac disease age 12-24. Participants will complete a series of online questionnaires assessing quality of life, patient activation, celiac symptoms, and self reported dietary adherence at the beginning and end of the study. Participants will also have their blood drawn to measure Tissue Transglutaminase IgA (TTG IgA) antibody and Deamidated Gliadin Peptide IgA (DGP IgA) at the beginning and end of the study. Lab draws can be done locally, and are at no cost to the participant. Patients are randomized to the intervention or control group based on enrollment TTG IgA. Intervention group receives 45 unique text messages over the 3 month study. A gift card is provided for participation in the study.
