Nearly one third of all patients with an eating disorder (ED) present with non-suicidal self-injury (NSSI). Although it is necessary to pay attention clinically to NSSI in ED patients due to an increased suicidal risk, there are limited data on potential predictors of NSSI in ED. We conducted this study to uncover predictors of NSSI in ED.
A total of 1355 ED patients who visited an ED clinic was evaluated through structured interviews by psychiatrists. The demographic and clinical characteristics of ED patients with NSSI (NSSI group) and ED patients without NSSI (non-NSSI group) were analyzed to identify potential predictors of NSSI in ED.
Among all ED individuals, 242 (17.9%) reported a history of NSSI. Compared to the non-NSSI group, the NSSI group reported more severe eating symptomatology, more comorbid psychiatric disease, and more suicidal risk. Comorbid alcohol use disorder, depressive disorder, purging behavior, history of suicide attempt, and rumination symptoms were uncovered as predictors of NSSI in ED.
The findings of the study are meaningful in that they highlight predictors of NSSI in ED in a large clinical sample. Understanding risk factors of NSSI and offering appropriate interventions are important to preventing suicidality in ED.
近三分之一的进食障碍（ED）患者存在非自杀性自伤（NSSI）行为。尽管由于自杀风险增加，临床上有必要关注 ED 患者的 NSSI 行为，但 ED 患者 NSSI 的潜在预测因素的数据有限。我们进行这项研究旨在揭示 ED 中 NSSI 的预测因素。
通过精神病医生的结构化访谈，对 1355 名 ED 患者进行评估。分析有 NSSI（NSSI 组）和无 NSSI（非 NSSI 组）ED 患者的人口统计学和临床特征，以确定 ED 中 NSSI 的潜在预测因素。
在所有 ED 个体中，有 242 人（17.9%）报告有 NSSI 史。与非 NSSI 组相比，NSSI 组报告了更严重的进食症状、更多的共病精神疾病和更高的自杀风险。共病酒精使用障碍、抑郁障碍、催吐行为、自杀未遂史和反刍症状被揭示为 ED 中 NSSI 的预测因素。
这项研究的结果具有重要意义，因为它们突出了在大型临床样本中 ED 中 NSSI 的预测因素。了解 NSSI 的风险因素并提供适当的干预措施对于预防 ED 中的自杀行为至关重要。
