Purpose

The purpose of this study was to examine the association between self-reported symptoms including fatigue and sleep disturbance with moderate-intensity physical activity among adults with type 2 diabetes.

Methods

This report was a secondary analysis of a cross-sectional study. Data from 53 participants with at least 6 days of repeated measures were used. Daytime physical activity and energy expenditure were assessed using a wrist-worn accelerometer at the free-living setting. Fatigue upon awakening was measured using a 0 to 10 scale. Sleep (eg, restorative sleep, sleep duration, and sleep efficiency) was measured using the Consensus Sleep Diary for Morning. Data were analyzed using linear mixed models by including within- and between-person effects.

Results

Participants were predominantly females (54.7%) with a mean age of 60.3 years. Controlling for the covariates, at the individual level (within-person), fluctuations in restorative sleep and fatigue upon awakening predicted moderate-intensity PA. Similarly, at the individual level, fluctuations in restorative sleep and fatigue upon awakening predicted average hourly energy expenditure. However, at the group level (between-person), no significant associations were found between fatigue and restorative sleep with moderate-intensity physical activity.

Conclusions

The study findings suggest that within-person fluctuations in fatigue and restorative sleep upon awakening predict daytime moderate-intensity physical activity. At the individual level, reducing fluctuations in fatigue and restorative sleep might encourage participation in physical activity. More research is warranted to uncover the underlying causes of fluctuations in fatigue and restorative sleep. Meanwhile, diabetes care and education specialists should pay attention to the within-person fluctuations of fatigue and sleep.

自我报告症状的波动预测成人2型糖尿病的客观体育活动

目的

这项研究的目的是检查2型糖尿病成年人自我报告的症状（包括疲劳和睡眠障碍）与中等强度的体育活动之间的关系。

方法

该报告是对横断面研究的次要分析。使用来自53名参与者的数据，这些参与者至少进行了6天的重复测量。在自由生活环境下，使用腕戴式加速度计评估白天的体育活动和能量消耗。使用0至10的标度测量唤醒时的疲劳。使用“早晨共识睡眠日记”测量睡眠（例如，恢复性睡眠，睡眠时间和睡眠效率）。通过使用人与人之间的影响，使用线性混合模型对数据进行了分析。

结果

参加者主要是女性（54.7％），平均年龄为60.3岁。在个体水平上（在人内）控制协变量时，恢复的睡眠和疲劳的波动会在唤醒时预测到中等强度的PA。同样，在个人层面上，唤醒时恢复性睡眠和疲劳的波动预计为平均每小时能量消耗。但是，在小组级别（人与人之间），疲劳和恢复性睡眠与中等强度的体育活动之间没有发现显着关联。

结论

研究发现表明，唤醒后人的疲劳和恢复性睡眠的波动预示着白天中等强度的体育锻炼。在个人层面上，减少疲劳和恢复性睡眠的波动可能会鼓励人们参加体育锻炼。有必要进行更多的研究来揭示疲劳和恢复性睡眠波动的根本原因。同时，糖尿病护理和教育专家应注意人内疲劳和睡眠的波动。
