BACKGROUND
To elucidate the populations and conditions where screen-based sedentary behaviors (SB) and internalizing symptoms are coupled, this review synthesized the evidence for factors that may moderate the associations between screen-based SB, depressive symptoms, and anxiety symptoms among youth.
METHODS
Two independent researchers conducted a systematic literature search of the Medline, psycINFO, and Scopus electronic databases in late 2018 for observational studies assessing moderators of the association between screen-based SB and depressive and anxiety symptoms. Studies among children and adolescents were eligible if moderation was assessed by statistical test (interaction) or stratification; and a narrative synthesis of eligible studies was conducted in accordance with PRISMA guidelines.
RESULTS
Seventy empirical studies (46 cross-sectional, 19 longitudinal, and 5 both) of 13 different moderating variables of screen-based SB-internalizing symptom associations met the eligibility criteria. Of these, 40 studies were of depressive symptoms, 2 were of anxiety symptoms, and 28 studies assessed symptoms of both. The most consistent evidence of moderation was for screen-type, such that TV viewing was not as strongly associated with internalizing symptoms compared to other forms of screen-based SB. There was also inconsistent evidence for physical activity buffering screen-based SB-internalizing symptom associations and for female sex amplifying screen-based SB-internalizing symptom associations. In general, the body of evidence for anxiety symptoms was more limited than that for depressive symptoms, and were therefore more inconsistent.
CONCLUSIONS
Screen-type, physical activity, and sex may influence the magnitude of screen-based SB-internalizing symptom coupling; highlighting potential sources of heterogeneity of screen-based SB-internalizing symptom associations. Additional studies aimed at understanding potential mechanistic explanations for the above moderators are needed prior to the development of tailored intervention strategies designed to decouple screen-based SB and internalizing symptoms among youth.
背景
为了阐明与屏幕为基础的久坐行为（SB）和内化症状相关的人群和条件，本综述综合了可能调节屏幕为基础的 SB、青少年抑郁症状和焦虑症状之间关联的因素的证据。
方法
两名独立研究人员于 2018 年末在 Medline、psycINFO 和 Scopus 电子数据库中进行了系统的文献检索，以评估评估屏幕为基础的 SB 与抑郁和焦虑症状之间关联的调节因素的观察性研究。如果通过统计检验（交互作用）或分层来评估调节作用，且有适当的研究则符合 PRISMA 指南，那么研究可以在儿童和青少年中进行。
结果
符合纳入标准的 70 项实证研究（46 项横断面研究、19 项纵向研究和 5 项同时研究）评估了屏幕为基础的 SB-内化症状关联的 13 个不同调节变量。其中，40 项研究是关于抑郁症状的，2 项研究是关于焦虑症状的，28 项研究评估了这两种症状。调节作用最一致的证据是屏幕类型，即与其他形式的屏幕为基础的 SB 相比，电视观看与内化症状的关联不那么强。有证据表明体力活动缓冲了屏幕为基础的 SB-内化症状的关联，女性性别增强了屏幕为基础的 SB-内化症状的关联，但证据不一致。一般来说，关于焦虑症状的证据比抑郁症状的证据更有限，因此也更不一致。
结论
屏幕类型、体力活动和性别可能会影响屏幕为基础的 SB-内化症状关联的程度；这突出了屏幕为基础的 SB-内化症状关联异质性的潜在来源。在制定旨在分离青少年屏幕为基础的 SB 和内化症状的针对性干预策略之前，需要进一步研究上述调节因素的潜在机制解释。
