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 型糖尿病的客观身体活动

目的

本研究的目的是检查自我报告的症状（包括疲劳和睡眠障碍）与 2 型糖尿病成人中等强度体育活动之间的关联。

方法

本报告是对横断面研究的二次分析。使用了至少 6 天重复测量的 53 名参与者的数据。在自由生活环境中使用腕戴式加速度计评估白天的体力活动和能量消耗。醒来时的疲劳使用 0 到 10 的量表来衡量。睡眠（例如，恢复性睡眠、睡眠持续时间和睡眠效率）是使用早晨的共识睡眠日记来测量的。使用线性混合模型分析数据，包括人内和人之间的影响。

结果

参与者主要是女性 (54.7%)，平均年龄为 60.3 岁。控制协变量，在个人水平（人内），恢复性睡眠的波动和醒来时的疲劳预测了中等强度的 PA。同样，在个人层面，恢复性睡眠的波动和醒来时的疲劳预测了平均每小时的能量消耗。然而，在群体层面（人与人之间），没有发现疲劳与中等强度体育活动的恢复性睡眠之间存在显着关联。

结论

研究结果表明，醒来时疲劳和恢复性睡眠的人体内波动预示着白天中等强度的身体活动。在个人层面，减少疲劳和恢复性睡眠的波动可能会鼓励参与体育活动。需要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疲劳和睡眠的人体内波动。
