To determine prospective associations between bedtime screen use behaviors and sleep outcomes one year later in a national study of early adolescents in the United States. We analyzed prospective cohort data from 9,398 early adolescents aged 11–12 years (48.4% female, 45% racial/ethnic minority) in the Adolescent Brain Cognitive Development Study (Years 2–3, 2018–2021). Regression analyses examined the associations between self-reported bedtime screen use (Year 2) and sleep variables (Year 3; self-reported sleep duration; caregiver-reported sleep disturbance), adjusting for sociodemographic covariates and sleep variables (Year 2). Having a television or Internet-connected electronic device in the bedroom was prospectively associated with shorter sleep duration one year later. Adolescents who left their phone ringer activated overnight had greater odds of experiencing sleep disturbance and experienced shorter sleep duration one year later, compared to those who turned off their phones at bedtime. Talking/texting on the phone, listening to music, and using social media were all prospectively associated with shorter sleep duration, greater overall sleep disturbance, and a higher factor score for disorders of initiating and maintaining sleep one year later. In early adolescents, several bedtime screen use behaviors are associated with adverse sleep outcomes one year later, including sleep disturbance and shorter weekly sleep duration. Screening for and providing anticipatory guidance on specific bedtime screen behaviors in early adolescents may be warranted.

青少年早期的就寝时间筛查使用行为和睡眠结果：一项前瞻性队列研究


在一项针对美国早期青少年的全国研究中，确定就寝时间筛查使用行为与一年后睡眠结果之间的潜在关联。我们分析了青少年大脑认知发展研究（2-3 年，2018-2021 年）中 9,398 名 11-12 岁早期青少年（48.4% 女性，45% 种族/少数民族）的前瞻性队列数据。回归分析检查了自我报告的就寝时间屏幕使用情况（第 2 年）与睡眠变量（第 3 年;自我报告的睡眠持续时间;照顾者报告的睡眠障碍）之间的关联，调整了社会人口学协变量和睡眠变量（第 2 年）。卧室里有电视或联网的电子设备与一年后较短的睡眠时间有潜在意义。与睡前关闭手机的青少年相比，在一夜之间激活手机铃声的青少年出现睡眠障碍的几率更大，一年后睡眠时间更短。打电话/发短信、听音乐和使用社交媒体都与较短的睡眠时间、更大的整体睡眠障碍以及一年后开始和维持睡眠的障碍的因子评分较高具有前瞻性相关性。在青少年早期，几种睡前筛查使用行为与一年后的不良睡眠结局相关，包括睡眠障碍和每周睡眠时间缩短。可能需要对青少年早期的特定就寝时间筛查行为进行筛查并提供预期指导。
