We aimed to identify the moderators of maintenance strategies' effects to assist cancer care organizations that offer peer mentoring physical activity programs.
A total of 161 inactive breast cancer survivors participated in a 12-month study and were randomized to one of three conditions at baseline. American Cancer Society's Reach to Recovery coaches delivered weekly calls to participants for the first 3 months. During Months 4-9, participants self-monitored PA and received feedback (Reach Plus) or additionally received monthly calls from coaches (Reach Plus Phone) or weekly text/email messages (Reach Plus Message). Moderate-to-vigorous PA (MVPA) was assessed using self-report and accelerometry at baseline, 3, 6, 9, and 12 months. We examined baseline demographics, cancer-specific, and social cognitive variables as potential moderators of MVPA. Using Latent Class Models, we identified three participant profiles. The profile was used as a moderator in longitudinal mixed-effects models of MVPA.
Profile 1 (44%) were married, White, in preparation, with higher income and higher social support. Profile 2 (41%) were older, office employees, African American, with higher PA self-efficacy. Profile 3 (15%) were diagnosed with stage 1 cancer, in contemplation, with higher MVPA and lower social support. At follow-ups, among those with Profile 1, Reach Plus participants had higher MVPA than other groups (f [Formula: see text].10). Among those with Profile 2, Reach Plus Message participants had higher mean MVPA than other groups (f [Formula: see text].11). Among those with Profile 3, Reach Plus Phone participants had higher MVPA than other groups, f [Formula: see text].11 (all ps < .05).
Organizations can choose PA maintenance strategies that are most effective for survivors with specific profiles.
Breast cancer survivors with specific profiles increase PA when receiving certain PA maintenance programs.

本研究旨在确定维持策略效果的调节因素，以协助提供同伴指导身体活动项目的癌症护理组织。
共有 161 名不活跃的乳腺癌幸存者参加了一项为期 12 个月的研究，并在基线时随机分为三组。美国癌症协会的“复苏之触”（Reach to Recovery）教练每 3 周给参与者打一次电话，为期 3 个月。在第 4-9 个月期间，参与者自行监测身体活动（PA）并接收反馈（Reach Plus），或者另外每月接受教练的电话（Reach Plus Phone）或每周短信/电子邮件（Reach Plus Message）。在基线、3、6、9 和 12 个月时，使用自我报告和加速度计评估中度至剧烈的 PA（MVPA）。我们检查了基线人口统计学、癌症特异性和社会认知变量，作为 MVPA 的潜在调节因素。使用潜在类别模型，我们确定了三个参与者的特征。在 MVPA 的纵向混合效应模型中，使用该特征作为调节因素。
特征 1（44%）为已婚、白人、准备阶段、收入较高且社会支持较高。特征 2（41%）为年龄较大、办公室员工、非裔美国人、身体活动自我效能较高。特征 3（15%）为诊断为 1 期癌症、处于考虑阶段、MVPA 较高且社会支持较低。在随访中，在具有特征 1 的参与者中，接受 Reach Plus 项目的参与者的 MVPA 高于其他组（f [Formula: see text].10）。在具有特征 2 的参与者中，接受 Reach Plus Message 项目的参与者的平均 MVPA 高于其他组（f [Formula: see text].11）。在具有特征 3 的参与者中，接受 Reach Plus Phone 项目的参与者的 MVPA 高于其他组，f [Formula: see text].11（所有 p <.05）。
组织可以选择对具有特定特征的幸存者最有效的 PA 维持策略。
具有特定特征的乳腺癌幸存者在接受某些 PA 维持项目时会增加 PA。
