The aim of this study was to investigate whether unhealthy weight control behaviors, fear of becoming obese, binge eating, impulsivity, and body mass index are associated with suicide ideation, repetitive self-mutilative behavior (SMB), suicide attempts, or both suicide attempts and SMB among female adolescent psychiatric inpatients.
Data were drawn from a clinical inpatient cohort of female adolescents (N = 300, aged 12-17 years) consecutively admitted for psychiatric hospitalization between April 2001 and March 2006. Information on adolescents' suicidal behavior, psychiatric Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV), diagnoses and weight control behaviors was obtained using the Schedule for Affective Disorder and Schizophrenia for School-Age Children Present and Lifetime (K-SADS-PL).
Even after adjustment with DSM-IV, affective, anxiety and eating disorders self-induced vomiting was significantly associated with SMB and suicide attempts with SMB. Impulsivity was related to suicide attempts with SMB. Excessive exercising was a significant finding only in those girls who had attempted suicide. Girls who had attempted suicide were more often overweight compared with girls without suicidal behavior.
Unhealthy weight control behaviors among adolescent girls were found to be strongly associated with suicidal behavior. Girls with a history of both suicide attempts and SMB seem to be the most disturbed group, with multiple weight loss methods and impulsivity. Girls who are overweight or exercise excessively may represent risk groups for attempted suicide.
本研究旨在探讨不健康的体重控制行为、对肥胖的恐惧、暴食、冲动和体重指数是否与女性青少年精神科住院患者的自杀意念、反复性自伤行为（SMB）、自杀企图或两者都有关。
数据来自 2001 年 4 月至 2006 年 3 月连续入院精神科住院的女性青少年（N=300，年龄 12-17 岁）的临床住院队列。使用儿童青少年情绪障碍和精神分裂症的诊断性定式检查（K-SADS-PL）获取青少年自杀行为、精神疾病诊断与统计手册（DSM-IV）诊断和体重控制行为的信息。
即使在调整了 DSM-IV 后，情感、焦虑和饮食障碍的自我诱导呕吐仍与 SMB 和有 SMB 的自杀企图显著相关。冲动与有 SMB 的自杀企图有关。过度运动仅在那些有自杀企图的女孩中是一个显著的发现。有自杀企图的女孩比没有自杀行为的女孩更常超重。
发现青少年女孩的不健康体重控制行为与自杀行为密切相关。有自杀企图和 SMB 史的女孩似乎是最受干扰的群体，她们使用多种减肥方法和冲动。超重或过度运动的女孩可能代表自杀未遂的高危人群。
