The purpose of this brief report is to describe the comorbid diagnoses and high-risk behaviors in a sample of adolescents with bulimia nervosa (BN).
Eighty adolescents enrolled in a RCT for BN that compared family-based therapy with individual-supportive psychotherapy completed the Eating Disorder Examination and the Schedule for Affective Disorder and Schizophrenia for School Age Children (K-SADS).
A total of 62.5% of the sample had a comorbid diagnosis as determined by the K-SADS. The majority of these presented with a major mood disorder. In addition, 25% of the sample had previously attempted suicide or self-harmed, 65.8% had consumed alcohol, and 30% had used illegal drugs. Suicidal behavior, drug use, and presence of a comorbid diagnosis were not related to diagnosis (full BN vs. subthreshold BN) or age.
Comorbidity and high-risk health behaviors in adolescents with BN mirror those of adults with BN although not at similar rates.
本简要报告旨在描述神经性贪食症（BN）青少年样本中的共病诊断及高危行为。
80名参加BN随机对照试验的青少年完成了饮食失调检查以及学龄儿童情感障碍和精神分裂症量表（K-SADS），该试验比较了家庭治疗与个体支持性心理治疗。
根据K-SADS确定，共有62.5%的样本存在共病诊断。其中大多数患有重度情绪障碍。此外，25%的样本曾有过自杀未遂或自我伤害行为，65.8%的人饮酒，30%的人使用过非法药物。自杀行为、药物使用及共病诊断与诊断类型（完全型BN与阈下型BN）或年龄无关。
BN青少年的共病及高危健康行为与BN成年人类似，尽管发生率不同。
