Explanation for the choice of comparators {6b}
Crohn’s disease, ulcerative colitis
DISEASE, ULCERATIVE COLITIS
We include patients with Crohn’s disease and ulcerative colitis with moderate disease activity as comparators and offer them one online lesson of 15–25 min on lifestyle guidance including general advice on healthy living. Specialized health personnel will present an educational video lesson. The patients in the comparison arm will receive the usual medical treatment with regular follow-up in the outpatient clinic. In this group, we will also monitor 7 days of physical activity level by accelerometry using the AX3 accelerometer [Axivity Ltd., Newcastle upon Tyne, UK] in weeks 0 and 12. The comparators have been chosen to represent the usual treatment and to help determine the efficacy of the intervention. Furthermore, all patients in the comparison arm will receive a wrist-worn heart rate monitor/fitness tracker (commercial) after completing a follow-up program identical to the patients in the intervention arm.
