中度和剧烈的体力活动（MVPA）对乳腺癌幸存者的益处已经得到了充分的证实。然而，大多数人都不够活跃。Fit 2 Thrive使用多阶段优化策略（MOST）方法来确定五种干预成分对该人群MVPA的影响。参与者[n=269;法师=52.5（SD=9.9）]接受核心干预（Fit 2 Thrive自我监测应用程序和Fitbit），并在全析因实验中随机分配到设置为开/关的五个干预组件：支持电话、豪华应用程序、好友、在线健身房和短信。干预措施在12周内实施，随访12周。在基线（T1）、12（T2）和24（T3）周通过加速度计测量MVPA。检查了所有组分在每个时间点的主效应和相互作用效应。试验保留率很高; 93%在T2或T3时具有有效的加速度计数据。在所有条件下，T2时MVPA（+53.6 min/周;p<0.001）和符合MVPA指南的存活者比例（+22.3%，p<0.001）显著增加，但在T3时维持但减弱（+24.6 min/周，p<0.001; +12.6%符合指南，p<0.001）。没有单独的组件显着改善MVPA，但在T2和T3时，支持呼叫、好友和短信的“开启”水平与“关闭”水平相比，增幅更大。Fit 2 Thrive核心干预（自我监测应用程序和Fitbit）有望增加乳腺癌幸存者的MVPA，但这些组件没有提供MVPA的额外增加。未来的研究应该在随机试验中评估核心干预措施，并确定哪些成分可以优化乳腺癌幸存者的MVPA行为。系统地测试五个技术支持的身体活动促进干预组件以及核心Fit 2 Thrive干预（Fit 2 Thrive自我监测应用程序和Fitbit），导致乳腺癌幸存者在干预后和12周随访时的身体活动增加。然而，与“关闭”相比，任何组件的增加都没有显著增加，这表明Fit 2 Thrive核心是一种有前途的可扩展策略，可以增加MVPA。
The benefits of moderate and vigorous physical activity (MVPA) for breast cancer survivors are well established. Yet, most are insufficiently active. Fit2Thrive used Multiphase Optimization Strategy (MOST) methodology to determine the effect of five intervention components on MVPA in this population. Participants [n=269;Mage=52.5 (SD=9.9)] received a core intervention (Fit2Thrive self-monitoring app and Fitbit) and were randomly assigned to five intervention components set to on/off in a full factorial experiment: support calls, deluxe app, buddy, online gym, and text messages. The intervention was delivered over 12 weeks with a 12-week follow-up. MVPA was measured via accelerometry at baseline (T1), 12 (T2) and 24 (T3) weeks. Main effects and interaction effects at each time point were examined for all components. Trial retention was high; 93% had valid accelerometer data at T2 or T3. Across all conditions, there were significant increases in MVPA (+53.6 min/week;p<0.001) and the proportion of survivors meeting MVPA guidelines (+22.3%, p<0.001) at T2 that were maintained but attenuated at T3 (+24.6 min/week, p<0.001; +12.6% meeting guidelines, p<0.001). No individual components significantly improved MVPA although, increases were greater for the “on” versus “off” level for support calls, buddy, and text messages at T2 and T3. The Fit2Thrive core intervention (self-monitoring app and Fitbit) is promising for increasing MVPA in breast cancer survivors, but the components provided no additional increases in MVPA. Future research should evaluate the core intervention in a randomized trial and determine what components optimize MVPA behaviors in breast cancer survivors. Systematically testing five technology-supported physical activity promotion intervention components alongside the core Fit2Thrive intervention (Fit2Thrive self-monitoring app and Fitbit) resulted in an increase in physical activity at post-intervention and at 12-week follow-up in breast cancer survivors. However, increases were not significantly greater with any component turned “on” versus “off” indicating the Fit2Thrive core is a promising scalable strategy for increasing MVPA.
