BACKGROUND The aim of this study was to examine the necessity of early intervention for students with potential bulimia by investigating how the eating attitudes of college students change and examining the relation between bulimic symptoms and depressive symptoms or the ability to cope with stress. METHODS The study participants were students who entered Hiroshima University in 2014. This study was conducted at two time points: Time-1 in 2014 and Time-2 in 2017. The Eating Attitudes Test-26 (EAT-26), Bulimic Inventory Test, Edinburgh (BITE), Beck Depression Inventory-II (BDI-II), and Coping Inventory for Stressful Situations (CISS) were administered at Times 1 and 2, and the responses were compared between the time points. Next, we compared the BDI-II scores of the BITE improved and worsened groups. In addition, we divided the participants into a clinical group, subthreshold group, and healthy group based on the BITE score at Time-1to compared their depressive symptoms and the ability to cope with stress. RESULTS Significantly higher BITE and BDI-II scores were recorded for both males and females at Time-2 than at Time-1. The BDI-II score at Time-1 was significantly higher in the BITE worsened group than in the BITE improved group. The BDI-II scores at Time-1 were significantly higher for both males and females in the subthreshold group than in the healthy group. Furthermore, significantly higher CISS-T and CISS-E scores were recorded at Time-1 for females in the subthreshold group than for females in the healthy group. CONCLUSIONS Based on these results, intervention for students the subthreshold group is important, and the key to intervention may be to address not only eating behaviors but also depressive symptoms and stress coping.

大学生饮食态度队列调查：抑郁症状干预和压力应对是阈下组预防贪食症的关键因素。

背景 本研究的目的是通过调查大学生的饮食态度如何变化以及检查贪食症状与抑郁症状或应对压力的能力之间的关系，来检验对潜在贪食症学生进行早期干预的必要性。方法 研究参与者是 2014 年进入广岛大学的学生。这项研究在两个时间点进行：2014 年的 Time-1 和 2017 年的 Time-2。饮食态度测试 26 (EAT-26)、暴食量表测试、爱丁堡 (BITE)、贝克抑郁量表-II (BDI-II) 和压力情况应对量表 (CISS) 在时间 1 和 2 进行管理，并在时间点之间比较响应。接下来，我们比较了 BITE 改善组和恶化组的 BDI-II 评分。此外，我们根据 Time-1 的 BITE 评分将参与者分为临床组、阈下组和健康组，以比较他们的抑郁症状和应对压力的能力。结果 男性和女性在时间 2 的 BITE 和 BDI-II 评分均显着高于时间 1。BITE 恶化组在 Time-1 的 BDI-II 评分显着高于 BITE 改善组。阈下组的男性和女性在 Time-1 的 BDI-II 评分均显着高于健康组。此外，在时间 1，亚阈值组女性的 CISS-T 和 CISS-E 评分显着高于健康组女性。结论 基于这些结果，对亚阈值组的学生进行干预很重要，干预的关键可能不仅是解决饮食行为，还包括抑郁症状和压力应对。试用注册 UMIN000029474 于 2017 年 10 月 9 日注册（追溯）。
