Testing Counseling and Mobile Health Interventions to Improve Physical Activity and Diet Quality in Survivors of Childhood Cancer

OUTLINE: Patients are randomized to Arms 1, 2, or 3. ARM 1: Patients receive a personalized clinician-led self-management telehealth session at baseline and 2 months. Patients with poor response at 3 months are randomized to Arm 2 or 4, otherwise patients receive the same telehealth session at months 4 and 6. Patients may receive 2 additional telehealth sessions after 6 months. ARM 2: Patients receive personalized goal setting for daily steps and activity (updated weekly) and 3 dietary goals (updated monthly) with social media peer support for 6 months. Patients with poor response at 3 months are randomized to Arms 1 or 4. Patients may receive personalized goal setting for daily steps and activity (updated monthly) and dietary goals (updated every 2 months) after 6 months. ARM 3: Patients receive no intervention for 12 months. After 12 months, they may optionally receive their choice of intervention for up to 6 months. ARM 4: If Arms 1 or 2 patients have poor response after 3 months, patients may be re-randomized to Arm 4. Patients receive remote sessions with a health coach every 1-2 weeks for 3 months. Patients may continue to receive remote sessions once a month after 3 months, during the maintenance phase (months 6-12).
