Principal Investigator: Nina S. Kadan-Lottick, MD, Children’s Oncology Group

The primary objective of the study is to review the effects of the multifaceted intervention on physical activity in AYA survivors of childhood cancer who do not meet physical activity guidelines. 

The multifaceted intervention includes using a Fitbit, receiving educational materials about physical activity, setting individualized goals, and having access to a social media peer support group. Patients in the control group will only use a Fitbit and receive the educational materials. 

The primary outcome measure of the trial is to increase the minutes of moderate-to-vigorous physical activity per day, compared with baseline. Secondary outcome measures include changes in cardiopulmonary fitness, body mass index, and resting heart rate. 

To be eligible, patients must be 15 to 20 years of age, have a prior diagnosis of a malignant neoplasm, and be in first continuous remission at the time of enrollment. For a complete list of eligibility criteria, please see the reference.
