这项研究的目的是确定结直肠癌幸存者在整个癌症经历中的主要锻炼模式，并确定它们与当前生活质量(QOL)的关系。参与者是130名结直肠癌幸存者，他们在过去4年内被诊断为结直肠癌患者并接受了辅助治疗。每个参与者都完成了一份邮寄的自填式问卷，评估了三个时间点的运动行为(诊断前、积极治疗、治疗后)、当前生活质量(身体、功能、情感、社交)和总体生活满意度(SWL)。结直肠癌幸存者在整个癌症经历中表现出四种主要的锻炼模式，分别被标记为维持者(在所有三个时间点都活跃)、暂时性复发者(诊断前活跃、治疗期间不活跃、治疗后活跃)、永久复发者(诊断前活跃、治疗期间不活跃、治疗后不活跃)和不锻炼者(在所有三个时间点都不活跃)。统计分析表明：(A)功能性生活质量是支持总体SWL的最少但最重要的生活质量维度，(B)运动水平从诊断前到积极治疗后下降，然后从积极治疗到治疗后上升，但没有恢复到诊断前水平，(C)在四种主要运动模式中，永久性复发者的生活质量最低。结论是，癌症治疗对锻炼水平有负面影响，那些在癌症治疗后未能重新开始锻炼的先前活跃的个人在1到4年后经历了最低的生活质量。研究结果将参考以前的研究进行讨论，并对未来的研究提出建议、实际意义和研究的局限性。
The purpose of this study was to identify the main exercise patterns of colorectal cancer survivors across the cancer experience and determine their relationship with current quality of life (QOL). Participants were 130 colorectal cancer survivors who were diagnosed within the previous 4 years and had received adjuvant treatment. Each participant completed a mailed, self-administered questionnaire that assessed exercise behavior at three time points (prediagnosis, active treatment, posttreatment), current QOL (physical, functional, emotional, social), and overall satisfaction with life (SWL). Colorectal cancer survivors exhibited four main exercise patterns across the cancer experience which were labeled maintainers (active at all three time points), temporary relapsers (active prediagnosis, inactive during treatment, active posttreatment), permanent relapsers (active prediagnosis, inactive during treatment, inactive posttreatment), and nonexercisers (inactive at all three time points). Statistical analyses showed that: (a) functional QOL was the least possessed but most important QOL dimension underlying overall SWL, (b) exercise levels decreased from prediagnosis to active treatment and then increased from active treatment to posttreatment but not back to prediagnosis levels, and (c) permanent relapsers reported the lowest QOL of the four main exercise patterns. It was concluded that cancer treatment has a negative impact on exercise levels and that those previously active individuals who fail to reinitiate exercise after cancer treatment experience the lowest QOL 1 to 4 years later. Findings are discussed in reference to previous research along with suggestions for future research, practical implications, and limitations of the study.
