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.
以往文献表明失眠症状与饮食失调之间存在联系，但缺乏关于这两个变量之间时间关联的实证数据。本研究旨在探讨大学生群体中失眠症状与饮食失调之间的双向关联。2023年10月17日至29日，共对11010名大学生进行了初步评估，并于6个月后的2024年4月15日至24日再次进行评估。饮食失调采用饮食失调检查问卷简表（EDE-QS）进行评估，而失眠症状则通过一份包含入睡困难、维持睡眠困难和早醒三个项目的问卷进行测量。我们的研究结果表明，基线时的失眠症状与6个月后饮食失调几率增加显著相关。此外，基线时的饮食失调在6个月随访时能显著预测失眠症状。本研究确定了大学生中失眠症状与饮食失调之间的前瞻性双向关系，为预防和治疗失眠症状及饮食失调的教育和临床方法提供了参考。
