背景：体力活动（PA）可能对预防青少年和年轻成人（AYA）儿童癌症幸存者的慢性疾病很重要。对AYA幸存者进行PA干预的随机对照试验（RCT）很少，但有必要确定在这一人群中增加PA的有效方案。因此，我们进行了一个试点随机对照试验，测试的可行性的移动的健康（mHealth）干预，以促进PA AYA survivors.Procedure：我们招募了14- 18岁的人谁是>= 1年后的癌症治疗西雅图儿童医院。为期10周的干预包括一个可穿戴PA跟踪设备（Fitbit Flex）和一个基于同伴的虚拟支持小组（Facebook小组）。研究人员帮助制定步骤目标，并每周颁发徽章。对照组接受常规护理。基线评估在随机化前进行，随访评估在干预期第8-10周进行。可行性标准定义如下。定性访谈评估可接受性。探索性结果包括PA，生活质量和PA的动机。结果：所有可行性标准均得到满足：我们招募了60名幸存者，干预参与者在大多数（71.5%）干预日佩戴Fitbit，>= 90%的参与者完成了问卷调查。定性数据证实了干预的可接受性。探索性分析发现，将干预受试者与对照组进行比较，在中度至剧烈PA（4.4 vs. 5.0 min/d; P = 0.92）或久坐时间（-4.5 vs. 1.0 min/d; P = 0.73）的变化方面，没有显著的校正组间差异。一些温和的差异被发现为PA的生活质量和动机的选择分量表。结论：这种mHealth PA干预是可行的，可以接受的AYA儿童癌症幸存者，并保证一个完全强大的随机对照试验。
Background: Physical activity (PA) may be important for preventing chronic diseases for adolescent and young adult (AYA) childhood cancer survivors. Randomized controlled trials (RCTs) of PA interventions for AYA survivors are sparse, but necessary to determine effective programs for increasing PA among this population. Thus, we conducted a pilot RCT, testing the feasibility of a mobile health (mHealth) intervention to promote PA among AYA survivors.Procedure: We recruited 14- to 18-year-olds who were >= 1-year post cancer therapy from Seattle Children's Hospital. The 10-week intervention consisted of a wearable PA-tracking device (Fitbit Flex) and a peer-based virtual support group (Facebook group). Research staff helped set step goals and awarded badges weekly. Controls received usual care. Baseline assessments occurred before randomization and follow-up assessments occurred during weeks 8-10 of the intervention period. Feasibility criteria are defined below. Qualitative interviews assessed acceptability. Exploratory outcomes included PA, quality of life, and motivation for PA.Results: All feasibility criteria were met: we recruited 60 survivors, intervention participants wore the Fitbit on the majority (71.5%) of intervention days, and >= 90% of all participants completed questionnaires. Qualitative data confirmed intervention acceptability. Exploratory analyses found no significant adjusted group differences for change in moderate-to-vigorous PA (4.4 vs. 5.0 min/day; P = 0.92) or sedentary time (-4.5 vs. 1.0 min/day; P = 0.73), comparing intervention subjects to controls. Some modest differences were found for select subscales of quality of life and motivation for PA.Conclusions: This mHealth PA intervention was feasible and acceptable to AYA childhood cancer survivors and warrants a fully powered RCT.
