Abstract
Background: This study explored eating disorders (ED) prevalences, comorbidity of ED with other mental disorders, and risk factors for ED among university students. ED included binge eating disorder (BED), bulimia nervosa (BN), or other specified feeding and eating disorders (OSFED).
Methods: A total of 3425 first-year university students in Sweden completed an online survey covering a range of criteria for psychiatric diagnoses, within the World Mental Health International College Student (WMH-ICS) initiative. Pearson's χ2 -tests were used to compare algorithm-based diagnostic prevalences for eating disorders and other comorbid psychiatric disorders between three groups: students with ED with or without other comorbid psychiatric disorders (A), students with psychiatric disorders but no ED comorbidity (B), and students with no psychiatric disorders (C). Multinomial logistic regression was used to calculate between-group comparisons of odds ratios for independent risk factors, where group B served as the reference group for comparisons with groups A and C.
Results: Of the total sample, 75% had at least one psychiatric disorder and 28% had at least one lifetime ED diagnosis. Students with ED (group A) reported higher prevalences for comorbid anxiety disorders, depression, suicidal behavior, and non-suicidal self-injury compared to students with psychiatric disorders but no ED (group B). Group A participants exhibited a higher risk of hazardous drinking, were more likely to have received medical treatment, and to identify as bisexual. Compared to group B, students with no psychiatric disorders (group C) were more likely to report better mental and physical health, but less likely to engage in hazardous drinking, and to have sought mental health treatment.
Conclusions: A large proportion of students with ED had additional psychiatric disorders, indicating that individuals with ED suffer from multiple mental health problems. It is crucial that student health services acquire competency to offer effective ED assessment and treatment.
背景：本研究探讨了大学生进食障碍（ED）的患病率、ED与其他精神障碍的合并率以及ED的风险因素。进食障碍包括暴饮暴食症（BED）、神经性贪食症（BN）或其他特定进食和进食障碍（OSFED）：共有 3425 名瑞典大学一年级学生完成了一项在线调查，调查内容涵盖了世界心理健康国际大学生（WMH-ICS）计划中的一系列精神病诊断标准。我们使用皮尔逊χ2检验比较了三组学生基于算法诊断的进食障碍和其他合并精神障碍的患病率：有或无其他合并精神障碍的ED学生（A组）、有精神障碍但无ED合并症的学生（B组）和无精神障碍的学生（C组）。多项式逻辑回归用于计算独立风险因素的组间几率比例比较，其中 B 组作为与 A 组和 C 组比较的参照组：在所有样本中，75%的人至少患有一种精神障碍，28%的人至少有一次终生 ED 诊断。与有精神障碍但无 ED 的学生（B 组）相比，有 ED 的学生（A 组）合并焦虑症、抑郁症、自杀行为和非自杀性自伤的发生率更高。A 组参与者有更高的危险饮酒风险，更有可能接受过医学治疗，并被认定为双性恋者。与 B 组相比，没有精神障碍的学生（C 组）更有可能报告自己的身心健康状况较好，但较少参与危险饮酒，也较少寻求心理健康治疗：结论：很大一部分患有 ED 的学生还患有其他精神疾病，这表明 ED 患者存在多种心理健康问题。学生健康服务机构必须具备提供有效 ED 评估和治疗的能力。
期刊介绍：
Journal of Eating Disorders is the first open access, peer-reviewed journal publishing leading research in the science and clinical practice of eating disorders. It disseminates research that provides answers to the important issues and key challenges in the field of eating disorders and to facilitate translation of evidence into practice.
The journal publishes research on all aspects of eating disorders namely their epidemiology, nature, determinants, neurobiology, prevention, treatment and outcomes. The scope includes, but is not limited to anorexia nervosa, bulimia nervosa, binge eating disorder and other eating disorders. Related areas such as important co-morbidities, obesity, body image, appetite, food and eating are also included. Articles about research methodology and assessment are welcomed where they advance the field of eating disorders.
