This study examined the associations between screen (computer, videogame, TV) and nonscreen (talking on the phone, doing homework, reading) sedentary time, and sleep in adolescents.
Data were drawn from AdoQuest, a prospective investigation of 1843 grade 5 students aged 10-12 years at inception in the greater Montreal (Canada) area.
Data for this cross-sectional analysis on screen and nonscreen sedentary time, sleep duration, and daytime sleepiness were collected in 2008-2009 from 1233 participants (67% of 1843) aged 14-16 years.
Computer and videogame use >2 hours per day was associated with 17 and 11 fewer minutes of sleep per night, respectively. Computer use and talking on the phone were both associated with being a short sleeper (<8 hour per night) (odds ratio =2.2 [1.4-3.4] and 3.0 [1.5-6.2], respectively), whereas TV time was protective (odds ratio=0.5 [0.3-0.8]). Participants who reported >2 hours of computer use or talking on the phone per day had higher daytime sleepiness scores (11.9 and 13.9, respectively) than participants who reported d2 hours per day (9.7 and 10.3, respectively).
Computer use and time spent talking on the phone are associated with short sleep and more daytime sleepiness in adolescents. Videogame time is also associated with less sleep. Clinicians, parents, and adolescents should be made aware that sedentary behavior and especially screen-related sedentary behavior may affect sleep duration negatively and is possibly associated with daytime sleepiness.
本研究旨在探讨青少年中屏幕（电脑、电子游戏、电视）和非屏幕（打电话、做作业、阅读）久坐时间与睡眠之间的关系。
数据来自于 AdoQuest，这是一项对加拿大大蒙特利尔地区 1843 名 5 年级学生（起始年龄为 10-12 岁）的前瞻性调查。
本横断面分析采用 2008-2009 年收集的 1233 名 14-16 岁参与者的屏幕和非屏幕久坐时间、睡眠时间和白天嗜睡数据。
每天使用电脑和电子游戏 >2 小时分别与每晚少睡 17 分钟和 11 分钟相关。使用电脑和打电话都与睡眠不足（每晚 <8 小时）有关（比值比=2.2 [1.4-3.4]和 3.0 [1.5-6.2]），而看电视时间则具有保护作用（比值比=0.5 [0.3-0.8]）。每天报告使用电脑或打电话 >2 小时的参与者白天嗜睡得分较高（分别为 11.9 和 13.9），而每天报告使用电脑或打电话 2 小时的参与者得分较低（分别为 9.7 和 10.3）。
在青少年中，使用电脑和打电话时间与睡眠不足和白天嗜睡增加有关。电子游戏时间也与睡眠时间减少有关。临床医生、家长和青少年应该意识到，久坐行为，特别是与屏幕相关的久坐行为，可能会对睡眠时间产生负面影响，并可能与白天嗜睡有关。
