Sleep problems and problematic Internet use have important implications for adolescent health; however, there have been no large-scale surveys using comprehensive measures. We examined the association between Internet use duration and sleep problems among Japanese adolescents.
We used data from the Lifestyle Survey of Adolescents collected in 2012, 2014, and 2017. We calculated the change in sleep status (insomnia, sleep duration, bedtime, and sleep quality) and Internet usage (screen time and services such as Internet surfing, social media use, streaming such as YouTube, and online gaming). A binary logistic model was estimated for insomnia. Generalized ordered logit models were employed for the ordinal outcomes (sleep duration, bedtime, sleep quality, and multidimensional sleep health). Sampling weights were constructed based on participation rate on survey years and selection rates from population statistics.
We analyzed data from 248 983 adolescents. Sleep status was unchanged; however, many adolescents used more Internet services and for longer durations. The odds ratio of Internet screen time for all sleep problems (insomnia, shorter sleep duration, later bedtime, and worse sleep quality) gradually declined. Longer Internet screen time (>5 hours) was strongly associated with all sleep problems. Internet services were also associated with sleep problems; particularly, social media use and online gaming were linked to later bedtimes.
Despite the decreased strength in the association between Internet usage and sleep problems, longer Internet time was strongly associated with sleep problems. Public health interventions should consider Internet use as an intervention target to improve adolescents' health.
睡眠问题和有问题的互联网使用对青少年健康具有重要影响；然而，尚未有使用综合测量方法的大规模调查。我们研究了日本青少年互联网使用时长与睡眠问题之间的关联。
我们使用了2012年、2014年和2017年收集的青少年生活方式调查数据。我们计算了睡眠状况（失眠、睡眠时间、就寝时间和睡眠质量）和互联网使用情况（屏幕使用时间以及诸如上网冲浪、使用社交媒体、观看YouTube等流媒体和在线游戏等服务）的变化。对失眠情况估计了二元逻辑模型。对有序结果（睡眠时间、就寝时间、睡眠质量和多维睡眠健康）采用了广义有序logit模型。根据调查年份的参与率和人口统计中的选择率构建抽样权重。
我们分析了248983名青少年的数据。睡眠状况没有变化；然而，许多青少年使用了更多的互联网服务且时长更长。互联网屏幕使用时间与所有睡眠问题（失眠、睡眠时间缩短、就寝时间推迟和睡眠质量变差）的比值比逐渐下降。较长的互联网屏幕使用时间（>5小时）与所有睡眠问题密切相关。互联网服务也与睡眠问题有关；特别是，使用社交媒体和在线游戏与就寝时间推迟有关。
尽管互联网使用与睡眠问题之间的关联强度有所下降，但较长的上网时间与睡眠问题密切相关。公共卫生干预措施应将互联网使用作为改善青少年健康的干预目标。
