Screen viewing is considered to have adverse impacts on the sleep of adolescents. Although there has been a considerable amount of research on the association between screen viewing and sleep, most studies have focused on specific types of screen viewing devices such as televisions and computers. The present study investigated the duration with which currently prevalent screen viewing devices (including televisions, personal computers, mobile phones, and portable video devices) are viewed in relation to sleep duration, sleep quality, and daytime sleepiness among Hong Kong adolescents (N = 762). Television and computer viewing remain prevalent, but were not correlated with sleep variables. Mobile phone viewing was correlated with all sleep variables, while portable video device viewing was shown to be correlated only with daytime sleepiness. The results demonstrated a trend of increase in the prevalence and types of screen viewing and their effects on the sleep patterns of adolescents.
屏幕观看被认为会对青少年的睡眠产生不利影响。尽管已经有大量关于屏幕观看与睡眠之间关联的研究，但大多数研究都集中在特定类型的屏幕观看设备上，如电视和电脑。本研究调查了香港青少年（N = 762）观看当前流行的屏幕观看设备（包括电视、个人电脑、手机和便携式视频设备）的时长与睡眠时间、睡眠质量和日间嗜睡之间的关系。电视和电脑观看仍然很普遍，但与睡眠变量无关。手机观看与所有睡眠变量相关，而便携式视频设备观看仅与日间嗜睡相关。结果表明，屏幕观看的普及率和类型呈上升趋势，且它们对青少年的睡眠模式有影响。
