Fit2ThriveMB: Optimization of a Physical Activity Promotion Intervention for Metastatic Breast Cancer Patients (Fit2ThriveMB)

28. září 2026 aktualizováno: Siobhan M Phillips, Northwestern University

The purpose of this study is to examine which of four components of a digital health intervention using an App and Fitbit meaningfully contribute to increased physical activity in Metastatic Breast Cancer Patients.

Participants will be asked to:

  • Wear a Fitbit and use an app, use 0 to 3 other components for 24 weeks and attend 6 or 12 coaching coaching calls in the first 12 weeks to increase daily steps.
  • Complete a questionnaire at baseline, week 12 and week 24
  • Complete functional performance test (FPT) via Zoom at baseline, week 12 and week 24
  • Wear a research activity monitor (Accelerometer) for 7 days at baseline, week 12 and week 24

Přehled studie

Detailní popis

Multiphase Optimization Strategy (MOST) methodology will be used to determine which intervention components or component combinations optimally increase daily steps in a 12-week intervention with a 12-week follow-up. MOST is a framework adapted from engineering that uses highly efficient factorial experiments to evaluate individual, and combined, effects of intervention components to determine which ones can be reduced, eliminated, or replaced to improve efficiency. Insufficiently active people with metastatic breast cancer (MBC) will receive a core intervention consisting of the FIt2ThriveMB app and Fitbit and be randomly assigned to four components, each with two-levels, under consideration for inclusion in the optimized intervention: 1) EHR-integration (on v. off); 2) coaching dose (weekly v. bi-weekly; 3) social+ (on v. off) and 4) goal-setting type (highly tailored v. static). The effects of increasing PA on symptom burden, other intensity activities (i.e. moderate to vigorous, light and sedentary), and functional performance and potential mediators and moderators of component effects will also be examined. Knowledge gained from this study will inform the development of more effective and scalable interventions to improve health and disease outcomes in this population.

Časové okno: Baseline, 12 and 24 weeks

Participants will be asked to indicate frequency of participation in strenuous (e.g., jogging), moderate (e.g., fast walking), and mild (e.g., easy walking) exercise over the past 7 days and average time spent in each activity. Activity frequencies will be multiplied by 9, 5, and 3 metabolic equivalents, respectively, and summed to create a total leisure time activity score. Weekly minutes of total, light, moderate, and vigorous activity will be calculated by multiplying the frequency and time of each activity. This value will be divided by 7 to obtain daily averages.

Short Physical Performance Battery (SPPB) Total Score
Časové okno: Baseline, 12 weeks, 24 weeks

The SPPB score is based on timed measures of gait speed, ability to rise from a chair, and standing balance. Gait speed will be measured using the better of two recorded times over a 4-meter course. Chair stand time will be measured as the time needed to rise five times from a seated position in a chair, with arms folded across the chest. For the balance test, participants will be asked to maintain their feet side-by-side, semi-tandem, and tandem positions for 10 seconds each. Each individual performance measure will be scored according to established cut points and aggregated for a total SPPB score.
