Technology use has been the focus of much concern for adolescents' sleep health. However, few studies have investigated the bidirectional association between sleep duration and time spent using technology. The aim of this study was to test whether time spent using technology predicted shorter sleep duration, and/or vice versa using cross-lagged analyses over one year. Participants were 1620 high school students in the 8th and 9th grade at baseline from 17 public schools in three middle Sweden communities. Students completed questionnaires at school during the spring of 2015 and 2016. Time spent using technology was self-reported and sleep duration was calculated from reported bed-times, wake-times and sleep onset latency. Time spent using technology significantly predicted shorter subsequent sleep duration and vice versa. Public health advocates educating others about the negative impacts of technology on sleep must also be mindful of the opposite, that many young people may turn to technological devices when experiencing difficulty sleeping.
技术的使用一直是青少年睡眠健康的关注焦点。然而，很少有研究调查睡眠持续时间和使用技术时间之间的双向关联。本研究的目的是通过为期一年的交叉滞后分析，检验使用技术的时间是否预示着睡眠时间更短，反之亦然。参与者是来自瑞典三个中部社区的 17 所公立学校的 8 年级和 9 年级的 1620 名高中生。学生在 2015 年和 2016 年春季在学校完成问卷调查。使用技术的时间是自我报告的，睡眠时间是根据报告的就寝时间、醒来时间和入睡潜伏期计算的。使用技术的时间显著预示着随后的睡眠时间更短，反之亦然。公共卫生倡导者在教育他人技术对睡眠的负面影响时，也必须注意到相反的情况，即许多年轻人在睡眠困难时可能会转向技术设备。
