Emerging research evidence suggests positive relationships between higher screen time and eating disorders. However, few studies have examined the prospective associations between screen use and eating disorder symptoms in early adolescents and how problematic screen use may contribute to symptom development.
We analyzed prospective cohort data from the Adolescent Brain Cognitive Development (ABCD) Study (N = 10,246, 2016-2020, ages 9-14). Logistic regression analyses were used to estimate the longitudinal associations between baseline self-reported screen time and eating disorder symptoms in year two. Logistic regression analyses were also used to estimate cross-sectional associations between problematic screen use in year two (either problematic social media or mobile phone use) and eating disorder symptoms in year two. Eating disorder symptoms based on the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) included fear of weight gain, self-worth tied to weight, engaging in compensatory behaviors, binge eating, and distress with binge eating.
Each additional hour of total screen time and social media use was associated with higher odds of fear of weight gain, self-worth tied to weight, compensatory behaviors to prevent weight gain, binge eating, and distress with binge eating two years later (odds ratio [OR] 1.05-1.55). Both problematic social media and mobile phone use were associated with higher odds of all eating disorder symptoms (OR 1.26-1.82).
Findings suggest greater total screen time, social media use, and problematic screen use are associated with more eating disorder symptoms in early adolescence. Clinicians should consider assessing for problem screen use and, when high, screen for disordered eating.
Level III: Evidence obtained from well-designed cohort or case-control analytic studies.
新出现的研究证据表明，较高的屏幕时间与饮食失调之间存在正相关关系。然而，很少有研究调查过屏幕使用与青少年早期饮食障碍症状之间的前瞻性关联，以及问题性屏幕使用如何导致症状发展。
我们分析了青少年大脑认知发展（ABCD）研究（2016-2020 年，年龄 9-14 岁，N=10246）的前瞻性队列数据。使用逻辑回归分析来估计基线自我报告的屏幕时间与第二年饮食障碍症状之间的纵向关联。逻辑回归分析还用于估计第二年问题性屏幕使用（即问题性社交媒体或手机使用）与第二年饮食障碍症状之间的横断面关联。基于儿童情感障碍和精神分裂症诊断性访谈表（KSADS-5）的饮食障碍症状包括对体重增加的恐惧、体重与自我价值的关联、进行补偿行为、暴食和对暴食的困扰。
每增加一小时的总屏幕时间和社交媒体使用与两年后更高的对体重增加的恐惧、体重与自我价值的关联、防止体重增加的补偿行为、暴食和对暴食的困扰的几率相关（比值比 [OR] 1.05-1.55）。问题性社交媒体和手机使用均与所有饮食障碍症状的几率增加相关（OR 1.26-1.82）。
研究结果表明，在青少年早期，更多的总屏幕时间、社交媒体使用和问题性屏幕使用与更多的饮食障碍症状相关。临床医生应考虑评估问题性屏幕使用情况，当问题严重时，应筛查饮食障碍。
III 级：来源于精心设计的队列或病例对照分析研究的证据。
