Abstract

Previous literature suggests a link between insomnia symptoms and eating disorders (EDs), yet empirical data on the temporal associations between these two variables are lacking. This study aimed to explore the bidirectional associations between insomnia symptoms and EDs in a population of college students. A total of 11,010 college students were assessed initially from October 17 to 29, 2023, and again 6 months later from April 15 to 24, 2024. EDs were assessed using the Short Form of the Eating Disorder Examination Questionnaire (EDE-QS), while insomnia symptoms were measured through a three-item questionnaire addressing difficulty initiating sleep, difficulty maintaining sleep, and early morning awakening. Our findings indicated that insomnia symptoms at baseline was significantly associated with increased odds of EDs six months later. Moreover, EDs at baseline were significantly predict insomnia symptoms at the six-month follow-up. This study identifies prospective bidirectional relationships between insomnia symptoms and EDs among college students, offering insights that may inform educational and clinical approaches to preventing and treating insomnia symptoms and EDs.

失眠症状与饮食失调的双向关联：中国大学生的两波纵向研究。

先前的文献表明失眠症状与饮食失调（EDs）之间存在联系，但缺乏关于这两个变量之间时间关联的经验数据。本研究旨在探讨大学生失眠症状与急症之间的双向关系。共有11010名大学生在2023年10月17日至29日进行了首次评估，并在6个月后的2024年4月15日至24日进行了第二次评估。EDs采用进食障碍检查问卷（ed - qs）的简短形式进行评估，而失眠症状则通过三项调查问卷进行测量，包括入睡困难、维持睡眠困难和早起。我们的研究结果表明，基线时的失眠症状与6个月后ed发生率的增加显著相关。此外，在6个月的随访中，基线ed可以显著预测失眠症状。本研究确定了大学生失眠症状和ed之间的前瞻性双向关系，为预防和治疗失眠症状和ed的教育和临床方法提供了见解。

期刊介绍： Eating Behaviors is an international peer-reviewed scientific journal publishing human research on the etiology, prevention, and treatment of obesity, binge eating, and eating disorders in adults and children. Studies related to the promotion of healthy eating patterns to treat or prevent medical conditions (e.g., hypertension, diabetes mellitus, cancer) are also acceptable. Two types of manuscripts are encouraged: (1) Descriptive studies establishing functional relationships between eating behaviors and social, cognitive, environmental, attitudinal, emotional or biochemical factors; (2) Clinical outcome research evaluating the efficacy of prevention or treatment protocols.
