目标：本研究前瞻性地调查了有失眠症状的乳腺癌患者的睡眠参数和体力活动的客观测量值之间的日常双向关系。方法：一个参与者亚组（N = 66）参加了一项随机对照试验，失眠与癌症共病，在干预前佩戴了7个24小时的活动记录仪。多水平模型检查了给定夜晚的睡眠参数（睡眠开始潜伏期，睡眠开始后觉醒[WASO]，总觉醒时间[TWT]，睡眠效率[SE]和总睡眠时间[TST]）是否预测了第二天的身体活动水平（每日活动计数和中度至剧烈身体活动的分钟数[MVPA]），反之亦然。结果如下：调整后的模型显示，较低的WASO（β =-0.12，SE = 0.07，p <0.05）、TWT（β =-0.14，SE = 0.05，p <0.05）和TST（β =-0.14，SE = 0.06，p <0.05）与第二天较大的每日活动计数波动显著相关。相反，较大的每日总计数波动与第二天晚上较高的WASO（β = 0.18，SE = 0.08，p <0.05），TWT（β = 0.12，SE = 0.04，p <0.05）和TST（β = 0.22，SE = 0.08，p <0.05）显著相关。结论：这些发现支持睡眠参数和体力活动之间的相互和复杂的关系。虽然他们没有证实身体活动对客观睡眠参数的可能有益影响，但他们认为成功的失眠治疗可以增加癌症患者的日常身体活动。
Objective: The present study prospectively investigated the day-to-day bidirectional relationships between objective measures of sleep parameters and physical activity among breast cancer patients with insomnia symptoms. Method: A subgroup of participants (N = 66) enrolled in a randomized controlled trial for insomnia comorbid with cancer wore an actigraphic recorder for seven 24-hr periods before the intervention. Multilevel models examined whether sleep parameters (sleep onset latency, wake after sleep onset [WASO], total wake time [TWT], sleep efficiency [SE], and total sleep time [TST]) on a given night predicted the levels of physical activity (daily activity counts and minutes of moderate to vigorous physical activity [MVPA]) the following day and vice versa. Results: Adjusted models revealed that a lower WASO (beta = -.12, SE = .07, p < .05), TWT (beta = -.14, SE = .05, p < .05), and TST (beta = -.14, SE = .06, p < .05) were significantly associated with a greater daily activity count fluctuation the next day. Conversely, greater total daily count fluctuations were significantly associated with a higher WASO (beta = .18, SE = .08, p < .05), TWT (beta = .12, SE = .04, p < .05), and TST (beta = .22, SE = .08, p < .05) the following night. Conclusions: These findings support a reciprocal and complex relationship between sleep parameters and physical activity. While they do not confirm a possible beneficial effect of physical activity on objective sleep parameters, they suggest that successful insomnia treatment could increase daily physical activity in patients with cancer.
