Understanding the factors that influence adherence to exercise programs is necessary to develop effective interventions for people with cancer. We examined the predictors of adherence to a supervised exercise program for participants in the ENGAGE study - a cluster randomized controlled trial that assessed the efficacy of a clinician-referred 12-week exercise program among men treated for prostate cancer. Demographic, clinical, behavioral, and psychosocial data from 52 participants in the intervention group were collected at baseline through self-report and medical records. Adherence to the supervised exercise program was assessed through objective attendance records. Adherence to the supervised exercise program was 80.3%. In the univariate analyses, cancer-specific quality of life subscales (role functioning r = 0.37, P = 0.01; sexual activity r = 0.26, P = 0.06; fatigue r = -0.26, P = 0.06, and hormonal symptoms r = -0.31, P = 0.03) and education (d = -0.60, P = 0.011) were associated with adherence. In the subsequent multivariate analysis, role functioning (B = 0.309, P = 0.019) and hormonal symptoms (B = -0.483, P = 0.054) independently predicted adherence. Men who experienced more severe hormonal symptoms had lower levels of adherence to the exercise program. Those who experienced more positive perceptions of their ability to perform daily tasks and leisure activities had higher levels of adherence to the exercise program. Hormonal symptoms and role functioning need to be considered when conducting exercise programs for men who have been treated for prostate cancer.
了解影响坚持锻炼计划的因素对于为癌症患者制定有效的干预措施至关重要。我们在ENGAGE研究中考察了参与一项有监督的锻炼计划的依从性预测因素，该研究是一项整群随机对照试验，评估了临床医生推荐的为期12周的锻炼计划对接受前列腺癌治疗的男性的疗效。通过自我报告和病历在基线时收集了干预组52名参与者的人口统计学、临床、行为和心理社会数据。通过客观出勤记录评估对有监督的锻炼计划的依从性。对有监督的锻炼计划的依从率为80.3%。在单因素分析中，癌症特异性生活质量量表（角色功能r = 0.37，P = 0.01；性活动r = 0.26，P = 0.06；疲劳r = -0.26，P = 0.06，激素症状r = -0.31，P = 0.03）和教育程度（d = -0.60，P = 0.011）与依从性相关。在随后的多因素分析中，角色功能（B = 0.309，P = 0.019）和激素症状（B = -0.483，P = 0.054）独立预测了依从性。经历更严重激素症状的男性对锻炼计划的依从性较低。那些对自己执行日常任务和休闲活动的能力有更积极看法的人对锻炼计划的依从性较高。在为接受过前列腺癌治疗的男性开展锻炼计划时，需要考虑激素症状和角色功能。
