PURPOSE
Determine the feasibility of a remotely delivered mobile health (mHealth)-supported intervention to improve diet and physical activity in hematologic malignancy survivors.
METHODS
Pilot randomized controlled trial of a 16-week intervention for improving diet and physical activity: individualized goal-setting (daily steps, sodium, saturated fat, added sugar intake) per feedback from mHealth trackers (Fitbit for activity; Healthwatch360 for diet), supplemented by a Facebook peer support group. Controls accessed the trackers without goal-setting or peer support. Everyone received standardized survivorship counseling with tailored advice from a clinician. Actigraphy and food frequency questionnaires assessed activity and diet at baseline and follow-up.
RESULTS
Forty-one participants (51.2% male; median age 45.1 years; 7.0 years from treatment) were randomized (24 intervention; 17 control). Fitbit and Healthwatch360 use were more common among intervention versus control participants (75.0% versus 70.6% and 50.0% versus 17.7% of eligible days, respectively). Most intervention participants (66.7%) engaged with Facebook; overall, 91.7% interacted with the study's mHealth applications. While no comparisons in activity or dietary outcomes between intervention versus control group met statistical significance, the intervention was associated with greater reductions in the targeted dietary factors and improvements in Healthy Eating Index-2015 score, moderate-vigorous physical activity time, and daily steps. Participant retention at 6 months was 90.2%.
CONCLUSIONS
An intervention for cardiovascular risk reduction based on individualized goal-setting enhanced by mHealth and social media peer support was feasible and acceptable among cancer survivors.
IMPLICATIONS FOR CANCER SURVIVORS
Effective and easily disseminated strategies that improve diet and physical activity in this population are needed.

目的
确定远程提供移动健康（mHealth）支持的干预措施改善血液恶性肿瘤幸存者饮食和身体活动的可行性。
方法
一项为期 16 周的改善饮食和身体活动的干预措施的试点随机对照试验：根据 mHealth 跟踪器（Fitbit 用于活动；Healthwatch360 用于饮食）的反馈进行个体化目标设定（每日步数、钠、饱和脂肪、添加糖摄入量），并辅以 Facebook 同行支持小组。对照组访问跟踪器但不设定目标或不获得同行支持。所有人都接受了标准化的生存咨询，并根据临床医生的建议进行了个性化咨询。活动记录仪和食物频率问卷在基线和随访时评估活动和饮食。
结果
41 名参与者（51.2%为男性；中位年龄 45.1 岁；治疗后 7.0 年）被随机分配（24 名干预组；17 名对照组）。与对照组相比，干预组使用 Fitbit 和 Healthwatch360 的更为常见（分别为 75.0%和 50.0%与 70.6%和 17.7%的合格天数）。大多数干预组参与者（66.7%）参与了 Facebook；总体而言，91.7%的参与者与研究的 mHealth 应用程序进行了互动。虽然干预组与对照组在活动或饮食结果方面没有任何比较达到统计学意义，但干预组与以下方面的改善相关：目标饮食因素的减少和健康饮食指数-2015 评分、中高强度体力活动时间和每日步数的增加。6 个月时的参与者保留率为 90.2%。
结论
基于 mHealth 和社交媒体同行支持的个体化目标设定增强的心血管风险降低干预措施在癌症幸存者中是可行且可接受的。
对癌症幸存者的意义
需要有效的且易于传播的策略来改善该人群的饮食和身体活动。
