摘要
背景：暴饮暴食症（BED）和自我伤害经常同时发生，并造成巨大的痛苦。尽管BED的发病率很高，但人们对它的了解往往很少，在研究中代表性不足。目前尚不清楚BED人群的自残率与其他饮食失调人群或对照组的自残率相比如何。研究人员进行了一项系统回顾和荟萃分析，目的是调查与其他饮食失调和对照组相比，BED患者发生自我伤害的频率。方法：本综述的方案采用预注册（PROSPERO参考号：CRD42023466201）。在线数据库PsycINFO， MEDLINE和Web of Science使用与BED和自残相关的关键术语进行了搜索，检索时间截止到2025年2月的出版物。纳入标准是测量BED和自残的研究。标题、摘要和全文均由独立评审员进行筛选。共确定了16项研究。完成了荟萃分析，以确定与其他饮食失调和非临床对照组相比，BED组中自我伤害的几率。评估偏倚风险和发表偏倚。结果：与神经性厌食症（OR = 0.7, 95%可信区间[CI] = 0.4-1.2）或其他特定进食障碍（OR = 0.7, 95% CI = 0.4-1.0）相比，BED患者的自我伤害率无差异。与非临床对照相比，BED组自我伤害的可能性是1.6倍（OR = 1.6, 95% CI = 1.0-2.5），与神经性贪食组相比，自我伤害的可能性几乎是一半（OR = 0.6, 95% CI = 0.4-0.8）。结论：与非临床人群相比，BED与更高的自我伤害发生率相关，在这方面应该像对待其他饮食失调一样对待。提高对BED群体中潜在的自我伤害的认识对于确保饮食失调的干预措施与自我伤害预防相结合至关重要。需要在非西方社会和跨性别和性别认同方面进行进一步的研究。
Self-harm in individuals who experience binge eating disorder: A systematic review and meta-analysis.
Background: Binge Eating Disorder (BED) and self-harm often co-occur and cause great distress. BED is often poorly understood and under-represented in research, despite high prevalence. It is unclear how self-harm in BED populations compares to rates of self-harm in other eating disorder populations or control groups. A systematic review and meta-analysis were undertaken with the aim of investigating how often self-harm occurs along with BED compared to other eating disorders and control groups.
Method: The protocol for this review was pre-registered (PROSPERO reference: CRD42023466201). Online databases, PsycINFO, MEDLINE and Web of Science, were searched using key terms relating to BED and self-harm, for publications dating up to February 2025. Inclusion criteria were studies that measured BED and self-harm. Titles, abstracts and full texts were screened by independent screeners. Sixteen studies were identified. Meta-analyses were completed to determine the odds of self-harm in BED groups compared to other eating disorders and non-clinical control groups. Risk of bias and publication bias were assessed.
Results: There was no difference in rate of self-harm between people experiencing BED compared to those experiencing Anorexia Nervosa (Odds Ratio [OR] = 0.7, 95% Confidence Interval [CI] = 0.4-1.2) or Other Specified Feeding and Eating Disorders (OR = 0.7, 95% CI = 0.4-1.0). Self-harm was 1.6 times more likely in BED groups compared to non-clinical controls (OR = 1.6, 95% CI = 1.0-2.5), and almost half as likely compared to Bulimia Nervosa groups (OR = 0.6, 95% CI = 0.4-0.8).
Conclusions: BED is associated with a higher prevalence of self-harm compared to non-clinical populations and should be approached similarly to other eating disorders in this regard. Increased awareness of the potential for self-harm in BED groups is vital to ensure interventions for eating disorders integrate self-harm prevention. Further research is required in non-western communities and across sexes and gender identities.
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.
