目的：与科技相关的睡前行为(如使用电脑)与青少年睡眠较差和较短有关；然而，对其他与睡眠有关的行为知之甚少。这项研究描述了睡前一小时内的一系列行为(即BT前行为[PBBS])，并研究了它们与学校和假期期间睡眠参数的关系(即分别限制和延长睡眠机会)。方法：在一个学期的最后一周和整个两周的假期中，来自普通社区的146名青少年(47.26%的男性，年龄M+/-标准差=16.2+/-1.0岁)完成了日常睡眠测量，并在学校和假期期间使用PBBS和PSAcog(睡眠前唤醒量表)和时型(Morningnerse-Evenness调查问卷)完成了日常睡眠测量。值得注意的是，玩电子游戏与较晚的学校和假期BT和较短的学校睡眠时间(控制了时间类型)有关。在度假期间，在线社交媒体与显著延长的入睡潜伏期有关，这种关系是通过较高的PSAcog来调节的。相反，在上学之夜，与家人在一起的时间与更早的BT和更长的睡眠时间相关。结论：与科技相关的PBB、视频游戏和在线社交媒体是导致睡眠更短和更差的危险因素，而与家人在一起的时间对睡眠时间有保护作用。在解决青少年的睡眠问题时，针对科技使用的潜在成瘾性质并减少PSAcog的治疗程序被牵连在内。(C)2016年青少年健康与医学学会。版权所有。
Purpose: Technology-related behaviors (e.g., computer use) before bedtime (BT) have been associated with poorer and shorter sleep in adolescents; however, less is known about other behaviors in relation to sleep. This study characterized a range of behaviors in the hour before bed (i.e., pre-BT behaviors [PBBs]) and examined their relationship with sleep parameters during school and vacation periods (i.e., restricted and extended sleep opportunities, respectively). Mechanistic roles of chronotype and cognitive presleep arousal (PSAcog) were also examined.Methods: During the last week of a school term and throughout a 2-week vacation, 146 adolescents (47.26% male, age M +/- standard deviation = 16.2 +/- 1.0 years) from the general community completed daily sleep measure using actigraphy, self-report measures on PBBs and PSAcog (Pre-sleep Arousal Scale) for both school and vacation periods, and chronotype (Morningnesse-Eveningness Questionnaire).Results: Adolescents engaged in a variety of behaviors before bed. Notably, playing video games was associated with significantly later school and vacation BT and shorter school sleep duration (controlling for chronotype). During vacation, online social media was associated with significantly longer sleep onset latency, and this relationship was mediated by higher PSAcog. In contrast, on school nights, spending time with family was associated with significantly earlier BT and longer sleep duration.Conclusions: Technology-related PBBs video games and online social media were risk factors for shorter and poorer sleep, whereas time with family was protective of sleep duration. In addressing sleep problems in adolescents, therapeutic procedures that target the potentially addictive nature of technology use and reduce PSAcog were implicated.
