OBJECTIVE
Screen time has been reported to be associated with binge-eating disorder (BED) among adolescents in the US; however, potential mediators remain unclear. This study aimed to evaluate depression symptoms as a mediator of the prospective association between screen time and BED.
METHOD
We utilized data from 9465 children (aged 9-11 years at baseline) from the Adolescent Brain Cognitive Development (ABCD) study (2016-2021). A generalized structural equation model was used to examine the prospective association between average daily screen time at baseline and BED at year 2, adjusting for baseline BED diagnosis, and other potential covariates (e.g., age, sex, and income). Mediation was examined using bias-corrected (BC) 95% confidence intervals for the indirect effect of baseline screen time on year 2 BED through depression symptoms (change from baseline to year 1).
RESULTS
One hundred and one participants (42.7% male, 49.4% racial/ethnic minority) met the criteria for BED in year 2. Participants were 9.9 years of age on average at baseline, 51.3% identified as male, and 43.1% identified as a racial/ethnic minority. Adjusting for covariates, screen time was prospectively associated with BED (OR = 1.09, 95% CI [1.03, 1.14], p = .005). Depression symptoms (B = .19, BC 95% CI [0.10, 0.28]) partially mediated (9.2%) the prospective association between screen time and BED.
DISCUSSION
Among US adolescents, higher baseline screen time was prospectively associated with BED diagnosis at year 2, and this relationship was partially mediated by increased depression symptoms. Preventive approaches targeting high screen use may have utility for reducing BED risk among adolescents.
PUBLIC SIGNIFICANCE
Among U.S. adolescents, higher screen time was prospectively associated with the incidence of BED. This association was partially mediated by the change in depressive symptoms. Preventive approaches targeting high screen use may have utility for reducing BED risk among adolescents.
目的
在美国青少年中，有研究报告称屏幕时间与暴食障碍（BED）有关；然而，潜在的中介因素仍不清楚。本研究旨在评估抑郁症状是否为屏幕时间与 BED 之间前瞻性关联的中介因素。
方法
我们利用了来自青少年大脑认知发展（ABCD）研究（2016-2021 年）的 9465 名儿童（基线时年龄为 9-11 岁）的数据。使用广义结构方程模型来检验基线时平均每日屏幕时间与第二年 BED 之间的前瞻性关联，调整了基线 BED 诊断和其他潜在协变量（例如年龄、性别和收入）。通过抑郁症状（从基线到第 1 年的变化），使用基线屏幕时间对第 2 年 BED 的间接效应的偏置校正（BC）95%置信区间来检验中介作用。
结果
101 名参与者（42.7%为男性，49.4%为少数族裔）在第 2 年符合 BED 标准。参与者的平均基线年龄为 9.9 岁，51.3%为男性，43.1%为少数族裔。调整协变量后，屏幕时间与 BED 呈前瞻性相关（OR=1.09，95%CI[1.03，1.14]，p=0.005）。抑郁症状（B=0.19，BC 95%CI[0.10，0.28]）部分中介（9.2%）了屏幕时间与 BED 之间的前瞻性关联。
讨论
在美国青少年中，较高的基线屏幕时间与第二年的 BED 诊断呈前瞻性相关，而这种关系部分是由抑郁症状的增加所介导的。针对高屏幕使用的预防方法可能对减少青少年 BED 风险具有实用价值。
意义
在美国青少年中，较高的屏幕时间与 BED 的发生率呈前瞻性相关。这种关联部分是由抑郁症状的变化介导的。针对高屏幕使用的预防方法可能对减少青少年 BED 风险具有实用价值。
