The purpose of this study was to systematically review the relationship between the timing of sedentary behaviours and access to sedentary activities in the bedroom with sleep duration and quality in children and youth. A secondary purpose was to examine whether these relationships differ when comparing screen-based and non-screen-based sedentary activities.
We searched four databases for peer-reviewed studies published between 1 January 2010 and 19 January 2021. Risk of bias assessment for each study and certainty of evidence were assessed using the GRADE framework.
We identified 44 eligible papers reporting data from 42 separate datasets and including 239 267 participants. Evening participation in screen-based sedentary behaviours and access to screen-based devices in the bedroom were associated with reduced sleep duration and quality. Daytime screen use was also associated with reduced sleep duration, although this was examined in relatively few studies. Whether performed during the day or night, non-screen-based sedentary behaviours were not consistently associated with sleep duration or quality. The quality of evidence was rated as low to very low for all outcomes.
In order to maximize sleep duration and quality, children and youth should be encouraged to minimize screen time in the evening and remove screens from bedrooms. (PROSPERO registration no.: CRD42020189082).
本研究的目的是系统评价儿童和青少年久坐行为的时间安排以及在卧室进行久坐活动的机会与睡眠时间和质量之间的关系。第二个目的是研究在比较基于屏幕和非基于屏幕的久坐活动时，这些关系是否存在差异。
我们在四个数据库中检索了2010年1月1日至2021年1月19日发表的同行评审研究。使用GRADE框架对每项研究的偏倚风险评估和证据的确定性进行评估。
我们确定了44篇符合条件的论文，这些论文报告了来自42个独立数据集的数据，包括239267名参与者。晚上参与基于屏幕的久坐行为以及在卧室使用基于屏幕的设备与睡眠时间缩短和质量下降有关。白天使用屏幕也与睡眠时间缩短有关，尽管这方面的研究相对较少。无论在白天还是晚上进行，非基于屏幕的久坐行为与睡眠时间或质量之间没有始终如一的关联。所有结果的证据质量被评为低到极低。
为了最大限度地延长睡眠时间和提高睡眠质量，应鼓励儿童和青少年尽量减少晚上的屏幕使用时间，并将屏幕设备移出卧室。（PROSPERO注册号：CRD42020189082）
