有监督的运动干预可以在老年乳腺癌幸存者中产生许多积极的健康结果。然而，为了保持这些好处，需要在监督计划结束后很长一段时间内保持定期锻炼。这可能很困难，因为在这一过渡期(即紧随有监督的锻炼计划之后的一段时间)，乳腺癌幸存者在缺乏训练有素的锻炼专家的现场直接监督的情况下。这项研究的目的是在完成乳腺癌辅助治疗的65岁以上的女性中，在为期12个月的监督锻炼计划结束后的6个月的随访期内，确定定期参加锻炼的关键决定因素。在监督锻炼计划结束时和6个月后，69名乳腺癌幸存者完成了从跨理论模型检查他们的锻炼行为和关键结构的调查。在调整了过渡点的体重状况和体力活动后，在过渡点自我效能较高的乳腺癌幸存者在离开监督锻炼计划6个月后更有可能活跃(优势比[95%可信区间，1.10[1.01-1.18])。类似地，在转变点有较高改变行为过程的乳腺癌幸存者更有可能是积极的(优势比[95%可信区间]，1.13[1.02-1.26])。这些发现表明，自我效能感和改变的行为过程在老年乳腺癌幸存者从监督计划向家庭计划转变的运动参与中扮演着重要的角色。
Supervised exercise interventions can elicit numerous positive health outcomes in older breast cancer survivors. However, to maintain these benefits, regular exercise needs to be maintained long after the supervised program. This may be difficult, as in this transitional period (i.e., time period immediately following a supervised exercise program), breast cancer survivors are in the absence of on-site direct supervision from a trained exercise specialist. The purpose of the present study was to identify key determinants of regular exercise participation during a 6-month follow-up period after a 12-month supervised exercise program among women aged 65+ years who had completed adjuvant treatment for breast cancer.At the conclusion of a supervised exercise program and 6 months later, 69 breast cancer survivors completed surveys examining their exercise behavior and key constructs from the Transtheoretical Model.After adjusting for weight status and physical activity at the transition point, breast cancer survivors with higher self-efficacy at the point of transition were more likely to be active 6 months after leaving the supervised exercise program (odds ratio [95% confidence interval, 1.10 [1.01-1.18]). Similarly, breast cancer survivors with higher behavioral processes of change use at the point of transition were more likely to be active (odds ratio [95% confidence interval], 1.13 [1.02-1.26]).These findings suggest that self-efficacy and the behavioral processes of change, in particular, play an important role in exercise participation during the transition from a supervised to a home-based program among older breast cancer survivors.
