Adherence to prescribed exercise is a challenge for cancer patients undergoing treatment. The changing pattern of exercise adherence over time cannot be fully understood by an overall measure of adherence. This study was aimed to identify the trajectory of exercise adherence and its predictors for women with breast cancer during their chemotherapy.
Participants were 78 women with breast cancer assigned to the exercise arm of a randomized control trial. Based on the weekly adherence rates in time and intensity, patients were classified as good (>100%), acceptable (80-100%), and poor (<80%) adherents. Data were analyzed using ordinal logistic hierarchical linear modeling.
The trajectories for both time and intensity adherence declined significantly. The decline in exercise-time adherence was significantly slower in women who reported higher interest in exercise. Women with higher perceived importance of exercise, early disease stage, and employed were more likely to be classified as good intensity adherents. Poorer weekly adherence for both exercise time and intensity was associated with higher fatigue level for that week.
Adherence to exercise adherence in breast cancer patients declined as the dose of exercise prescription increased. Factors influencing overall adherence and adherence trend were identified.
坚持规定的锻炼对正在接受治疗的癌症患者来说是一项挑战。通过总体依从性测量无法完全理解锻炼依从性随时间的变化模式。本研究旨在确定乳腺癌女性患者在化疗期间锻炼依从性的轨迹及其预测因素。
参与者为78名被分配到一项随机对照试验锻炼组的乳腺癌女性患者。根据每周在时间和强度上的依从率，患者被分为依从性良好（>100%）、可接受（80 - 100%）和依从性差（<80%）的人群。使用有序逻辑分层线性模型对数据进行分析。
时间和强度依从性的轨迹均显著下降。对锻炼兴趣较高的女性，其锻炼时间依从性的下降明显较慢。认为锻炼重要性较高、疾病分期较早且有工作的女性更有可能被归类为强度依从性良好的人群。锻炼时间和强度的每周依从性较差与该周较高的疲劳水平相关。
随着锻炼处方剂量的增加，乳腺癌患者的锻炼依从性下降。确定了影响总体依从性和依从趋势的因素。
