非自杀性自伤（NSSI）在进食障碍（ED）成人中升高，尤其是在暴饮暴食和/或净化（B/P）行为的个体中发生率更高。尽管总体上青少年中NSSI的患病率显著升高，但儿童和青少年艾德样本中的NSSI研究不足。有一些证据表明，B/P组和仅限制组之间的NSSI患病率升高;然而，这一发现并没有得到一致的报道，该领域的研究排除了某些诊断组（例如，其他特定的进食或进食障碍）。我们的目的是确定跨诊断样本的青少年ED患者（n = 155）报告终生或上个月NSSI的比率，以及这些比率在最近从事B/P行为与仅限制的个体之间是否存在差异。40.6%的样本存在终身NSSI，23.2%的参与者报告在治疗前一个月参与了NSSI。与未报告B/P行为的个体相比，报告近期B/P行为的个体更有可能报告上个月（p = 0.005，OR = 5.57）和终生（p = 0.004，OR = 4.39）的NSSI。这些结果表明，与仅支持限制的患者相比，支持B/P行为的儿童和青少年艾德治疗患者的NSSI风险增加。需要研究来阐明可能解释这种关联的病因学因素以及整个ED过程中NSSI的纵向变化。
Nonsuicidal self-injury (NSSI) is elevated in adults with eating disorders (EDs), with a particularly increased incidence among individuals who engage in binge eating and/or purging (B/P) behaviors. Despite substantially elevated prevalence of NSSI in adolescence in general, NSSI in child and adolescent ED samples is under-studied. There is some evidence for elevated prevalence of NSSI between B/P and restriction-only groups; however, this finding is not consistently reported and research in this area has excluded certain diagnostic groups (e.g., other specified feeding or eating disorder). Our aim was to identify the rates at which a trans-diagnostic sample of adolescent patients with EDs (n = 155) report lifetime or past-month NSSI, and whether these rates differ between individuals who engaged in recent B/P behaviors vs. restriction only. Lifetime NSSI was present in 40.6% of the sample, and 23.2% of participants reported engaging in NSSI in the month prior to treatment. Individuals who reported recent B/P behaviors were more likely to report past-month (p = .005, OR = 5.57) and lifetime (p = .004, OR = 4.39) NSSI compared to individuals who did not report B/P behaviors. These results suggest an increase in risk for NSSI in child and adolescent patients in ED treatment who endorse B/P behaviors compared to patients who endorse restriction only. Research is needed to clarify the etiologic factors that may explain this association and the longitudinal changes in NSSI throughout the course of EDs.
