Young adults (YAs) are vulnerable to insomnia and mood disturbance. YAs also engage in back-lit device use which has been implicated in the development and maintenance of insomnia. This study explored the association between device use, mood disturbance, and insomnia symptoms in YAs.
Two thousand three hundred and ninety students at a Canadian university, aged 18-35 years.
Cross-sectional online survey MEASUREMENTS: Participants self-reported duration and frequency of back-lit device use before sleep and during the night. The Insomnia Severity Index and the Hospital Anxiety and Depression Scale were used to measure symptoms. Univariate and multivariate logistic regressions explored associations between device use behaviors and insomnia symptoms. A hierarchical regression analysis identified the unique contribution of back-lit device use on insomnia severity adjusting for mood disturbance, age, and sex.
Using a back-lit device for 1-2 hours after lights out (adjusted odds ratio [AOR] = 1.50, p < 0.001), being awakened by a device (AOR = 1.34, p = 0.002), and believing that device use negatively impacts sleep (AOR = 2.27, p < 0.001) were associated with insomnia symptoms. Depression contributed to the greatest unique variance to insomnia (11.8%), followed by anxiety (7.2%). Duration of device use after lights out, being awakened by a device and a negative perception of device use on sleep accounted for an additional 3%.
Device use contributed to insomnia symptoms over and above mood disturbance, age, and biological sex in YAs. Additional research is needed to determine the direction of effect and inform prevention/intervention programs specific to device use and insomnia symptomology in this population.
年轻人易患失眠和情绪障碍。年轻人还会在睡前使用有背光的设备，而这种行为可能会导致并维持失眠。本研究旨在探讨年轻人中设备使用、情绪障碍与失眠症状之间的关系。
加拿大一所大学的 2390 名年龄在 18-35 岁的学生。
横断面在线调查。
参与者自我报告睡前和夜间使用有背光设备的时间和频率。使用失眠严重程度指数和医院焦虑抑郁量表来测量症状。单变量和多变量逻辑回归探讨了设备使用行为与失眠症状之间的关联。分层回归分析确定了在调整情绪障碍、年龄和性别后，使用有背光设备对失眠严重程度的独特贡献。
在熄灯后使用有背光设备 1-2 小时（调整后的优势比 [OR] = 1.50，p < 0.001）、被设备唤醒（OR = 1.34，p = 0.002）以及认为设备使用对睡眠有负面影响（OR = 2.27，p < 0.001）与失眠症状相关。抑郁对失眠的独特贡献最大（11.8%），其次是焦虑（7.2%）。熄灯后使用设备的时间、被设备唤醒以及对设备使用对睡眠的负面影响，这三个因素共解释了失眠症状的另外 3%。
在年轻人中，设备使用除了情绪障碍、年龄和生物性别外，还与失眠症状有关。需要进一步的研究来确定因果关系，并为该人群的设备使用和失眠症状制定特定的预防/干预计划。
