PRIMARY OBJECTIVES:
I. Determine the feasibility of recruiting and retaining hematologic malignancy and hematopoietic cell transplantation (HCT) survivors in a randomized cardiovascular (CV) risk reduction mobile health (mHealth) counseling intervention.
II. Develop and refine a protocol to engage participants using an existing social medial platform and commercially available mHealth tools to reinforce lifestyle goals.
OUTLINE: Participants are randomized to 1 of 2 groups.
INTERVENTION GROUP: Participants receive individualized goal-setting and coaching in relation to physical activity and diet, supplemented with peer support through the study's social media platform, over 4 months. They also have access to mHealth apps including Fitbit and Healthwatch that provide feedback on physical activity and diet.
CONTROL GROUP: Participants receive general information about physical activity and diet, and access to Fitbit and Healthwatch.
After completion of study treatment, participants are followed up at 2 months and at 1 year.
