BACKGROUND
Peer support can extend the reach of physical activity (PA) interventions. In previous studies, peer support via weekly counseling calls increased PA at 3 and 6 months among breast cancer survivors, compared to contact control. However, effects were attenuated at 6 months. Interventions targeting PA maintenance among cancer survivors are limited. Hence, we extended prior work to identify effective PA maintenance interventions.
PURPOSE
Following a 3-month PA intervention, the study compared the effects of three 6-month interventions on PA at 12 months.
METHODS
One hundred and sixty-one inactive breast cancer survivors participated in a 12-month randomized controlled trial. Intervention delivery was uniform for the first 3-months: all participants received a weekly call with their peer coach to encourage PA. Following month 3, participants self-monitored PA and received feedback reports (Reach Plus) or additionally received, a monthly phone call (Reach Plus Phone), or weekly text message (Reach Plus Message). Moderate-to-vigorous PA (MVPA) was measured using self-report (7 Day PAR) and accelerometry at baseline, 3, 6, 9, and 12 months.
RESULTS
At 3 months, there were significant within group increases in self-reported and objectively measured MVPA with no between-group differences (ps > .05). At 6 months, adjusted longitudinal models showed that Reach Plus Message reported an additional 23.83 (SD = 6.33, f2 = .12) min/week of MVPA and Reach Plus Phone reported an additional 18.14 min/week (SD = 5.15, f2 =.16) versus Reach Plus. Results were similar at 9 months. At 12 months, Reach Plus Message and Reach Plus Phone both out-performed Reach Plus (ps = .04 and .05 respectively and effect sizes f2 = .11 and f2 = .21 respectively). Accelerometer data showed similar patterns: Reach Plus Message and Reach Plus Phone out-performed Reach Plus at 6 (f2 = .20) and 9 months (f2 = .09).
CONCLUSION
Phone calls from peer mentors and text messaging can support PA maintenance among breast cancer survivors.

背景
同伴支持可以扩大身体活动 (PA) 干预的范围。在之前的研究中，与接触对照组相比，每周通过咨询电话进行的同伴支持在乳腺癌幸存者中增加了 3 个月和 6 个月的 PA，但在 6 个月时效果减弱。针对癌症幸存者 PA 维持的干预措施有限。因此，我们扩展了之前的工作，以确定有效的 PA 维持干预措施。
目的
在为期 3 个月的 PA 干预之后，该研究比较了三种 6 个月干预措施对 12 个月时 PA 的影响。
方法
161 名不活跃的乳腺癌幸存者参加了一项为期 12 个月的随机对照试验。前 3 个月的干预措施是统一的：所有参与者都接受了每周一次的电话与他们的同伴教练通话，以鼓励 PA。在第 3 个月后，参与者自我监测 PA 并收到反馈报告（Reach Plus）或另外每月收到一次电话（Reach Plus Phone）或每周一次短信（Reach Plus Message）。在基线、3、6、9 和 12 个月时，使用自我报告（7 天 PAR）和加速度计测量中度至剧烈体力活动 (MVPA)。
结果
在 3 个月时，自我报告和客观测量的 MVPA 均有显著的组内增加，而组间无差异（p >.05）。在 6 个月时，调整后的纵向模型显示，与 Reach Plus 相比，Reach Plus Message 报告每周额外增加 23.83 分钟（SD = 6.33，f2 =.12）的 MVPA，而 Reach Plus Phone 报告每周额外增加 18.14 分钟（SD = 5.15，f2 =.16）。在 9 个月时结果相似。在 12 个月时，Reach Plus Message 和 Reach Plus Phone 均优于 Reach Plus（p 值分别为.04 和.05，效应大小 f2 =.11 和 f2 =.21）。加速度计数据显示出类似的模式：Reach Plus Message 和 Reach Plus Phone 在 6 个月（f2 =.20）和 9 个月（f2 =.09）时的表现均优于 Reach Plus。
结论
来自同伴导师的电话和短信可以支持乳腺癌幸存者的 PA 维持。
