Adolescents' daily lives have been disrupted during the Coronavirus disease 2019 (COVID-19) pandemic. It remains unclear how changes in adolescents' daily physical and social behaviours affect their sleep. The present study examined the daily and average effects of physical activity and social media use (i.e., video chatting, texting, and social networking sites) on adolescent girls' sleep during the COVID-19 pandemic. Adolescent girls aged 12-17 years (N = 93; 69% White) from a larger longitudinal study completed a 10-day daily diary protocol during state-mandated stay-at-home orders. Girls reported on daily sleep (duration, timing, quality), physical activity, and social media use during COVID-19. Multilevel modelling was used to examine the within- and between-person effects of physical activity and social media on sleep duration, timing, and quality during the 10-day period. Between-person associations indicate that youth with greater social media use (texting, video chatting, and social networking) and less physical activity had later sleep timing across the 10-day study period. Only video chatting was associated with shorter sleep duration. There were no within-person effects of physical activity or social media activities on sleep outcomes. Findings indicate that physical activity and social media use may impact later adolescent sleep timing during the COVID-19 pandemic. It will be critical for research to examine the potential long-term costs of delayed sleep timing, and whether targeting specific youth behaviours associated with sleep and circadian disruption improve mental and physical health during the COVID-19 pandemic and beyond.
青少年的日常生活在 2019 年冠状病毒病（COVID-19）大流行期间受到了干扰。目前尚不清楚青少年日常生活中身体和社会行为的变化如何影响他们的睡眠。本研究考察了 COVID-19 期间青少年女孩的日常和平均体力活动和社交媒体使用（即视频聊天、短信和社交网络）对睡眠的影响。一项较大的纵向研究中的 12-17 岁青少年女孩（N=93；69%为白人）在州政府强制居家令期间完成了为期 10 天的日常日记方案。女孩们报告了 COVID-19 期间的日常睡眠（持续时间、时间、质量）、体力活动和社交媒体使用情况。多水平模型用于检验 COVID-19 期间体力活动和社交媒体对睡眠持续时间、时间和质量的个体内和个体间影响。个体间关联表明，社交媒体使用（短信、视频聊天和社交网络）较多且体力活动较少的青少年在整个 10 天研究期间睡眠时间较晚。只有视频聊天与较短的睡眠时间有关。体力活动或社交媒体活动对睡眠结果没有个体内影响。研究结果表明，体力活动和社交媒体使用可能会影响 COVID-19 大流行期间青少年较晚的睡眠时间。研究将重点关注睡眠延迟的潜在长期成本，以及针对与睡眠和昼夜节律紊乱相关的特定青少年行为是否会在 COVID-19 大流行期间及以后改善心理健康和身体健康。
