This study investigated longitudinal relationships between social media usage and binge eating (BE) in early adolescence and explored potential moderating effects of sex and BMI.
Data from the Adolescent Brain Cognitive Development (ABCD) Study, including 1940 participants aged 11 to 12 years at Wave 1, were analyzed over three annual waves. Social media addiction (SMA) scores and time spent on social media were calculated from self-report questionnaires. BE symptoms were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia (KSADS-5) through self-reports and parent reports. Modified Poisson regression was used to estimate associations, adjusting for demographic and behavioral covariates.
SMA symptoms, but not time on social media, were cross-sectionally and prospectively associated with BE. Prospective associations were stronger in male adolescents and differed by baseline body weight. The consistently high SMA group showed the strongest association with follow-up BE compared with the consistently low SMA group, whereas decreased and increased SMA groups showed similarly positive associations.
SMA scores predict BE in early adolescence, with differentiation in the relationship by sex and weight status. Further observational and interventional research could illuminate underlying mechanisms and test the value of targeting social media-addictive behaviors to mitigate the risk of disordered eating.
本研究调查了青少年早期社交媒体使用与暴饮暴食（BE）之间的纵向关系，并探讨了性别和体重指数（BMI）的潜在调节作用。
对青少年大脑认知发展（ABCD）研究的数据进行分析，该研究包括1940名在第1波时年龄为11至12岁的参与者，数据来自三个年度波次。通过自我报告问卷计算社交媒体成瘾（SMA）得分和在社交媒体上花费的时间。通过自我报告和家长报告，使用儿童情感障碍和精神分裂症量表（KSADS-5）评估BE症状。使用修正泊松回归估计关联，并对人口统计学和行为协变量进行调整。
SMA症状而非在社交媒体上花费的时间，在横断面和前瞻性上均与BE相关。前瞻性关联在男性青少年中更强，且因基线体重而异。与持续低SMA组相比，持续高SMA组与随访时的BE关联最强，而SMA降低组和升高组显示出类似的正向关联。
SMA得分可预测青少年早期的BE，且在性别和体重状况方面关系存在差异。进一步的观察性和干预性研究可以阐明潜在机制，并测试针对社交媒体成瘾行为以降低饮食失调风险的价值。
