Brief summary

This phase III trial compares a multi-component mobile health and social media physical activity intervention versus wearing a physical activity tracker alone among adolescent and young adult childhood cancer survivors. Regular physical activity helps maintain healthy weight, energy levels, and health. Adolescents and young adults who complete treatment for cancer are often less active. They may gain weight and have more health problems compared to people the same age who have not had treatment for cancer. Comparing the 2 programs will help researchers learn how to increase physical activity levels over time and also how changes in physical activity levels affect health and quality of life over time.

Detailed description

PRIMARY OBJECTIVE: I. To evaluate the effects of a multi-component physical activity intervention including a Fitbit, individualized goal setting, and a social media peer support group compared to the control condition (Fitbit only) on physical activity among adolescent and young adult survivors of childhood cancer (AYA survivors) who do not meet physical activity guidelines. SECONDARY OBJECTIVES: I. To evaluate the effects of a multi-component physical activity intervention including a Fitbit, individualized goal setting, and a social media peer support group compared to the control condition (Fitbit only) on biomarkers predictive of cardiometabolic health among adolescent and young adult survivors of childhood cancer (AYA survivors) who do not meet physical activity guidelines. II. To evaluate the effects of a multi-component physical activity intervention including a Fitbit, individualized goal setting, and a social media peer support group compared to the control condition (Fitbit only) on health-related quality of life among adolescent and young adult survivors of childhood cancer (AYA survivors) who do not meet physical activity guidelines. OUTLINE: Participants are randomized to 1 of 2 groups. INTERVENTION GROUP: Participants receive educational materials about physical activity. INTENSIVE PHASE (24 WEEKS): Participants wear a physical activity tracker (Fitbit) daily as well as receiving weekly reminders from study staff to wear it. They also receive goal setting sessions each week (by text, phone call, etc.) to set personalized step count goals using the Fitbit application (app). Lastly, participants receive an invitation to follow and post on an online social media peer support group (Instagram), where study staff provide encouraging advice and messages about physical activity 2-3 times per week, announce badges/awards every week, and moderate a forum to discuss physical activity and use of the Fitbit. MAINTENANCE PHASE (24 WEEKS): Participants wear a Fitbit daily but do not receive reminders to wear it. They also set their own step count goals weekly and check in with study staff monthly for assistance with goal setting. Participants take the lead posting content on the Instagram account moderated by the study staff. Study staff only post once per week with general physical activity-related questions and provide no badges. CONTROL GROUP: Participants receive educational materials about physical activity and wear a Fitbit daily for 48 weeks.

Post-menarchal female patients are eligible as long as they agree to use an effective contraceptive method (including abstinence) during study participation * Patients with previous hematopoietic stem cell transplant (HSCT) are excluded * Note: Patients with previous autologous HSCT, chimeric antigen receptor T-cell (CAR T-cell) therapy, and other cellular cancer therapies can participate as long as all other eligibility criteria are satisfied

Design outcomes

Primary

MeasureTime frameDescription
Minutes of moderate-to-vigorous physical activity (MVPA) per day12 monthsModerate-to-vigorous physical activity (MVPA) will be measured with a research-grade accelerometer which records minutes of MVPA over a 7 day period. This is used to calculate MVPA minutes at baseline and 12 months post-baseline. Total minutes above the moderate-intensity threshold will be divided by the number of valid days to obtain minutes of MVPA per day. Will report the mean difference in average daily minutes of MVPA from baseline to 12 months, by arm, with corresponding 95% confidence intervals.

Secondary

MeasureTime frameDescription
Cardiopulmonary fitness12 monthsCardiopulmonary fitness is an objective biomarker of exercise capacity and will be assessed by the 2-Minute Step Test. Participants complete the 2-Minute Step Test at baseline and 12 months post-baseline. Steps are counted during the test. Will report the mean difference in steps from baseline to 12 months, by arm, with corresponding 95% confidence intervals.
Resting heart rate12 monthsResting heart rate will be taken using the Fitbit physical activity tracker heart rate monitor prior to the participant initiating the 2-Minute Step Test at baseline and 12 months. Will report the mean difference, by arm, with corresponding 95% confidence intervals.
Health-related quality of life (HRQOL) Global Functioning12 monthsHRQOL will be measured at baseline and 12 months with the Pediatric Quality of Life inventory (PedsQL) 4.0 Generic Core Scales. The Global Functioning score will be transformed to a scale from 0-100, in which higher scores indicate better HRQOL. Will report the mean difference, by arm, with corresponding 95% confidence intervals.
Health-related quality of life (HRQOL) Physical Functioning12 monthsHRQOL will be measured at baseline and 12 months with the Pediatric Quality of Life inventory (PedsQL) 4.0 Generic Core Scales. The Physical Functioning score will be transformed to a scale from 0-100, in which higher scores indicate better HRQOL. Will report the mean difference, by arm, with corresponding 95% confidence intervals.
Health-related quality of life (HRQOL) Social Functioning12 monthsHRQOL will be measured at baseline and 12 months with the Pediatric Quality of Life inventory (PedsQL) 4.0 Generic Core Scales. The Social Functioning score will be transformed to a scale from 0-100, in which higher scores indicate better HRQOL. Will report the mean difference, by arm, with corresponding 95% confidence intervals.
Health-related quality of life (HRQOL) Fatigue12 monthsHRQOL will be measured at baseline and 12 months with the Pediatric Quality of Life inventory (PedsQL) 4.0 Generic Core Scales.
