The purpose of this study was to determine associations of objectively assessed moderate-to-vigorous intensity physical activity (MVPA) and sedentary time with psychological health outcomes including depression symptoms, anxiety symptoms, and overall satisfaction with life in colon cancer survivors.
Colon cancer survivors (N = 180) from Alberta, Canada (n = 91), and Western Australia (n = 89) completed a mailed survey that assessed depression symptom severity, state anxiety, and satisfaction with life (SWL). Sedentary time and MVPA were assessed using the Actigraph(®) GT3X+ accelerometer (60-s epochs) via a 7-day monitoring protocol. MVPA and sedentary time were corrected for wear time and then examined as quartiles (Q). Multivariate analysis of variance was used to examine associations of MVPA and sedentary time with psychological health.
There was a significant association between psychological health outcomes and objectively assessed MVPA [Wilks' λ = 0.886, F(3382.2) = 2.156, p = 0.024] that suggested a small and significant association between MVPA and SWL (p = 0.032). A significant multivariate analysis of variance (MANOVA) [Wilks' λ = 0.945, F(3159) = 3.1, p = 0.028] suggested participants meeting guidelines reported significantly fewer anxiety symptoms (M(diff) = -1.23, p = 0.027) and higher perceptions of SWL (M(diff) = 3.0, p = 0.008). No significant associations emerged for sedentary time [Wilks' λ = 0.956, F(9382.3) = 0.788, p = 0.628].
Contrary to previously published research using self-reports, objectively assessed MVPA and sedentary time were not associated with depression symptoms. Objectively assessed MVPA was associated with SWL and anxiety outcomes in colon cancer survivors.
Colon cancer survivors should continue to engage in regular and sustained MVPA for the accrual of psychological health benefits.
本研究旨在确定客观评估的中度至剧烈强度身体活动（MVPA）和久坐时间与结肠癌幸存者心理健康结果之间的关联，这些心理健康结果包括抑郁症状、焦虑症状和对生活的总体满意度。
来自加拿大艾伯塔省（n = 91）和西澳大利亚州（n = 89）的180名结肠癌幸存者完成了一项邮寄调查，该调查评估了抑郁症状严重程度、状态焦虑和生活满意度（SWL）。使用Actigraph(®) GT3X +加速度计（60秒时段）通过7天监测方案评估久坐时间和MVPA。对MVPA和久坐时间进行佩戴时间校正，然后作为四分位数（Q）进行检查。使用多变量方差分析来检查MVPA和久坐时间与心理健康之间的关联。
心理健康结果与客观评估的MVPA之间存在显著关联[威尔克斯'λ = 0.886，F(3,382.2) = 2.156，p = 0.024]，这表明MVPA与SWL之间存在小而显著的关联（p = 0.032）。一项显著的多变量方差分析（MANOVA）[威尔克斯'λ = 0.945，F(3,159) = 3.1，p = 0.028]表明，符合指南的参与者报告的焦虑症状显著较少（M（差异）=-1.23，p = 0.027），对SWL的感知更高（M（差异）= 3.0，p = 0.008）。久坐时间未出现显著关联[威尔克斯'λ = 0.956，F(9,382.3) = 0.788，p = 0.628]。
与先前发表的使用自我报告的研究相反，客观评估的MVPA和久坐时间与抑郁症状无关。客观评估的MVPA与结肠癌幸存者的SWL和焦虑结果相关。
结肠癌幸存者应继续进行规律且持续的MVPA，以获得心理健康益处。
