Sleep disorders, such as insomnia, have been associated with extended periods of inactive, sedentary behaviour. Many factors contribute to insomnia, including stress, irregular sleep patterns, mental health issues, inadequate sleeping schedules, diseases, neurological disorders and prescription medications.
Identification of the patterns of sedentary time and its duration in adults with acute insomnia and healthy controls to determine the statistically significant sedentary bouts; comparison of the sedentary behaviour patterns in acute insomnia adults with healthy controls.
We investigate the daytime actigraphy data and identify temporal patterns of inactivity among adults with acute insomnia and healthy adults. Seven days of actigraphy data were utilised to calculate sedentary time and bouts of variable duration based on a threshold of activity counts (<100 counts per minute). Statistical analysis was applied to investigate sedentary bouts and total sedentary time during weekdays and weekend. A logistic regression model has been used to determine the significance of sedentary bouts.
We found that individuals with acute insomnia accumulate a significant amount of their sedentary time in medium (6-30 minutes and 31-60 minutes) and longer (more than 60 minutes) duration bouts in comparison to healthy adults. Furthermore, a low p value for total sedentary time (2.54 ⋅ 10-4) association with acute insomnia supports the finding that acute insomnia individuals are significantly more engaged in sedentary activities compared to healthy controls. Also, as shown by the weekend vs weekday analysis, the physical and sedentary activity patterns of acute insomnia adults demonstrate higher variability during the weekdays in comparison to the weekend.
The results of the present study demonstrate that adults with acute insomnia spend more time in low-intensity daily physical activities compared to healthy adults.
睡眠障碍，如失眠，与长时间不活动、久坐行为有关。许多因素会导致失眠，包括压力、不规律的睡眠模式、心理健康问题、不适当的睡眠时间、疾病、神经紊乱和处方药物。
确定急性失眠症患者和健康对照组成年人久坐时间及其持续时间的模式，以确定具有统计学意义的久坐时间；比较急性失眠症成年人和健康对照组的久坐行为模式。
我们调查了白天的活动记录仪数据，并确定了急性失眠症成年人和健康成年人的白天不活动时间模式。利用 7 天的活动记录仪数据，根据活动计数（<100 次/分钟）的阈值计算久坐时间和不同持续时间的久坐时间。应用统计分析来研究工作日和周末的久坐时间和总久坐时间。使用逻辑回归模型确定久坐时间的显著性。
我们发现，与健康成年人相比，急性失眠症患者在中（6-30 分钟和 31-60 分钟）和长（超过 60 分钟）时间的久坐时间更长。此外，急性失眠症与总久坐时间（2.54 ⋅ 10-4）的低 p 值表明，与健康对照组相比，急性失眠症患者更倾向于久坐活动。此外，正如周末与工作日的分析所示，与周末相比，急性失眠症成年人在工作日的身体和久坐活动模式表现出更高的变异性。
本研究的结果表明，与健康成年人相比，急性失眠症成年人每天进行低强度身体活动的时间更多。
