To further examine the relationship between bedtime media use and sleep in adults by taking relevant covariates into account and testing hypothesised mediating and moderating pathways.
Bedtime media use and sleep outcomes were examined by questionnaire in 4188 adults (59 % women, aged 19-94 years) from the Specchio cohort based in Geneva, Switzerland. We tested associations between bedtime media use and sleep (bedtimes, rise times, sleep latency, sleep duration, sleep quality, insomnia, and daytime sleepiness), adjusting for prior sleep, mental health, and health behaviours; whether bedtime media use mediates associations between individual susceptibility factors (age, chronotype, and mental health) and sleep; and whether individual susceptibility factors moderate associations between bedtime media use and sleep.
Often using a screen in the 30 minutes before going to sleep at night was associated with a late bedtime (≥midnight; OR [95 % CI] = 1.90 [1.44,2.51], p < 0.001), a short sleep duration (<7 h; 1.21 [1.01,1.46], p < 0.05), and excessive daytime sleepiness (Epworth score >9; 1.47 [1.25,1.74], p < 0.001), adjusting for all covariates. Bedtime media use partly mediated the association between younger age and an evening chronotype and these sleep outcomes. Mental health moderated the association between bedtime media use and sleep quality/insomnia, such that the former was only associated with poorer sleep quality/insomnia among individuals with better mental health.
Frequent bedtime media use was associated with various sleep outcomes, independently of relevant covariates. Limiting the use of screens at bedtime is important to promote sleep among adults. Individuals with poorer mental health likely require additional support to improve their sleep quality.
通过考虑相关协变量并测试假设的中介和调节途径，进一步研究成年人睡前媒体使用与睡眠之间的关系。
在瑞士日内瓦的 Specchio 队列中，对 4188 名成年人（59%为女性，年龄 19-94 岁）进行了问卷调查，以了解睡前媒体使用和睡眠结果。我们调整了先前的睡眠、心理健康和健康行为，测试了睡前媒体使用与睡眠（就寝时间、起床时间、睡眠潜伏期、睡眠时间、睡眠质量、失眠和白天嗜睡）之间的关联；睡前媒体使用是否在个体易感性因素（年龄、昼夜类型和心理健康）与睡眠之间的关联中起中介作用；以及个体易感性因素是否调节睡前媒体使用与睡眠之间的关联。
经常在晚上睡觉前 30 分钟内使用屏幕与晚睡（≥午夜；OR[95%CI]=1.90[1.44,2.51]，p<0.001）、睡眠时间短（<7 小时；1.21[1.01,1.46]，p<0.05）和白天过度嗜睡（Epworth 评分>9；1.47[1.25,1.74]，p<0.001）有关，调整了所有协变量。睡前媒体使用部分中介了年龄较小和夜间型昼夜类型与这些睡眠结果之间的关联。心理健康调节了睡前媒体使用与睡眠质量/失眠之间的关联，使得前者仅与心理健康较好的个体的睡眠质量/失眠相关。
频繁的睡前媒体使用与各种睡眠结果有关，与相关协变量无关。限制睡前使用屏幕对于促进成年人的睡眠很重要。心理健康较差的个体可能需要额外的支持来改善睡眠质量。
