Abstract

Objective: To examine the role of insomnia as a mediator between worrying and mental health and whether the association between worrying and insomnia is moderated by the levels of exercise frequency.

Methods: A cross-sectional online survey was conducted during the fourth wave of the COVID-19 outbreak in Hong Kong (n = 988). Participants' insomnia, psychological distress, and exercise frequency were evaluated. A mediation analysis was performed to examine the direct effect of COVID-19 worries and their indirect effect through insomnia on psychological distress.

Results: A significant indirect effect of COVID-19 worries through insomnia was found on psychological distress (beta = 0.18, SE = 0.02, 95% CI = 0.14-0.22, p < .001). The significant index of moderated mediation supported the moderating effect of exercise frequency on the indirect effect of COVID-19 worries on psychological distress (IMM = 0.06, SE = 0.02, 95% CI = 0.02-0.10, p = .006). The conditional indirect effects of insomnia on psychological distress were significant in individuals with mean and higher exercise frequency but not in those with lower exercise frequency.

Conclusion: COVID-19 worries increased psychological distress through the worsening of sleep, and such an array of COVID-19 worries on insomnia was moderated by exercise frequency. Engaging more frequent exercise could reduce insomnia in people with less COVID-19 worries.

失眠和锻炼在新冠肺炎对香港中国人心理困扰的担忧中的作用：一个温和的调解模型。

目的：研究失眠在焦虑与心理健康之间的中介作用，以及焦虑与失眠之间的关系是否受运动频率水平的调节。方法：在香港第四波新冠肺炎疫情期间进行横断面在线调查（n = 988）。对参与者的失眠、心理困扰和运动频率进行评估。对新冠肺炎担忧的直接影响及其通过失眠对心理困扰的间接影响进行了中介分析。结果：发现新冠肺炎焦虑通过失眠对心理困扰有显著的间接影响（β = 0.18，SE = 0.02，95%CI = 0.14-0.22，p p = .006）。失眠对心理困扰的条件间接影响在平均运动频率和较高运动频率的个体中显著，但在较低运动频率的群体中不显著。结论：新冠肺炎焦虑通过睡眠的恶化而增加心理压力，而运动频率对新冠肺炎对失眠的一系列担忧起到了调节作用。更频繁地锻炼可以减少新冠肺炎担忧较少的人的失眠。

期刊介绍： Behavioral Sleep Medicine addresses behavioral dimensions of normal and abnormal sleep mechanisms and the prevention, assessment, and treatment of sleep disorders and associated behavioral and emotional problems. Standards for interventions acceptable to this journal are guided by established principles of behavior change. Intending to serve as the intellectual home for the application of behavioral/cognitive science to the study of normal and disordered sleep, the journal paints a broad stroke across the behavioral sleep medicine landscape. Its content includes scholarly investigation of such areas as normal sleep experience, insomnia, the relation of daytime functioning to sleep, parasomnias, circadian rhythm disorders, treatment adherence, pediatrics, and geriatrics. Multidisciplinary approaches are particularly welcome. The journal’ domain encompasses human basic, applied, and clinical outcome research. Behavioral Sleep Medicine also embraces methodological diversity, spanning innovative case studies, quasi-experimentation, randomized trials, epidemiology, and critical reviews.
