The aims of the present study were to analyze the association of sleep patterns with academic and cognitive performance in adolescents, and to test the potential mediating effect of different activities of screen media usage on this association.
A sample of 269 adolescents (140 boys) aged 14 years from the baseline data of the Deporte, ADOlescencia y Salud study completed questionnaires about sleep quality, cognitive performance, and leisure-time sedentary behaviors. Sleep duration was objectively computed using a wrist-worn GENEActiv accelerometer and academic performance was analyzed through school records.
Sleep quality (but not sleep duration) was associated with all the academic performance indicators (all p<0.05). Analysis of covariance revealed higher grades among adolescents with better sleep quality (PSQI≤5; all p<0.05). These analyses showed no differences regarding cognitive performance. Internet use time was revealed as a mediator of the association between sleep quality and academic performance, being significant for all academic performance indicators (P ranging from 15.5% to 16.0%).
The association between sleep quality and academic performance in adolescents is mediated by time of Internet use. Overall, reducing Internet use in adolescents could be an achievable intervention for improving sleep quality, with potentially positive effects on academic performance.
本研究旨在分析青少年的睡眠模式与学业和认知表现之间的关系，并检验屏幕媒体使用的不同活动在这种关系中的潜在中介作用。
Deporte、ADOlescencia y Salud 研究的基线数据中，有 269 名 14 岁的青少年（140 名男性）完成了关于睡眠质量、认知表现和休闲时间久坐行为的问卷。使用腕戴式 GENEActiv 加速度计客观计算睡眠时间，通过学校记录分析学业成绩。
睡眠质量（而非睡眠时间）与所有学业表现指标均相关（均 p<0.05）。协方差分析显示，睡眠质量较好的青少年（PSQI≤5；均 p<0.05）的成绩更高。这些分析表明认知表现没有差异。互联网使用时间被揭示为睡眠质量与学业表现之间关联的中介因素，对所有学业表现指标均具有统计学意义（P 范围为 15.5%至 16.0%）。
青少年的睡眠质量与学业表现之间存在关联，其受到互联网使用时间的中介影响。总的来说，减少青少年的互联网使用可能是改善睡眠质量的可行干预措施，对学业表现可能产生积极影响。
