BACKGROUND
Lung cancer patients undergo various treatments leading to sleep problems, rest-activity circadian rhythms disruption, and reduced levels of physical activity. It is important to understand the relationships among these variables. Appropriate interventions can possibly be implemented to improve sleep quality in lung cancer patients.
OBJECTIVE
The objective of this study was to examine the relationships of circadian rhythms and physical activity with objective sleep parameters in 106 of Taiwanese lung cancer patients.
METHODS
This study used a cross-sectional design. The instruments included an actigraph to measure the objective sleep parameters (total sleep time [TST], sleep efficiency, and sleep-onset latency [SOL]), rest-activity circadian rhythms (r24 [24-hour autocorrelation coefficient] and I < O [in-bed less than out-of-bed dichotomy index]), and physical activity frequency (UP activity mean). The daily physical activity amount in minutes was measured by the Bouchard 3-day physical activity record.
RESULTS
Patients performing light-intensity physical activity of 295 min/d or greater had better values for the TST, sleep efficiency, SOL, r24, and I < O than those performing less than 295 min/d (all P < .05). Significant predictors of the TST included age (β = -.31), I < O (β = .32), and UP activity mean (β = -.42). Predictors of the SOL included current treatment (β = .20), I < O (β = -.28), UP activity mean (β = .51), and 24-hour light-activity minutes (β = -.23).
CONCLUSIONS
Marked circadian rhythms and adequate light-intensity physical activity may improve sleep quality in lung cancer patients.
IMPLICATIONS FOR PRACTICE
Adequate light-intensity physical activity can be an effective intervention to improve sleep quality in lung cancer patients.
背景
肺癌患者接受多种治疗，这会导致睡眠问题、休息 - 活动昼夜节律紊乱以及身体活动水平降低。了解这些变量之间的关系很重要。可能可以实施适当的干预措施来改善肺癌患者的睡眠质量。
目的
本研究的目的是在106名台湾肺癌患者中检验昼夜节律和身体活动与客观睡眠参数之间的关系。
方法
本研究采用横断面设计。所使用的仪器包括一个活动记录仪，用于测量客观睡眠参数（总睡眠时间 [TST]、睡眠效率和入睡潜伏期 [SOL]）、休息 - 活动昼夜节律（r24 [24小时自相关系数] 和I < O [卧床时间少于起床时间二分指数]）以及身体活动频率（UP活动均值）。通过布沙尔3天身体活动记录来测量每日身体活动量（以分钟为单位）。
结果
每天进行295分钟或更长时间轻度身体活动的患者，其TST、睡眠效率、SOL、r24和I < O的值优于每天进行少于295分钟身体活动的患者（所有P <.05）。TST的显著预测因素包括年龄（β = -.31）、I < O（β =.32）和UP活动均值（β = -.42）。SOL的预测因素包括当前治疗（β =.20）、I < O（β = -.28）、UP活动均值（β =.51）和24小时光照 - 活动分钟数（β = -.23）。
结论
明显的昼夜节律和充足的轻度身体活动可能会改善肺癌患者的睡眠质量。
对实践的启示
充足的轻度身体活动可以作为改善肺癌患者睡眠质量的有效干预措施。
