自杀是青少年死亡的主要原因，但发现其风险往往具有挑战性。许多精神疾病都有食欲不振的共同症状，而且众所周知，患有这些疾病的人自杀的风险更大。然而，食欲减退和自杀风险之间的关系还有待研究。特别是对青少年来说，关于食欲减退的问题可能比关于心理健康的敏感问题更容易回答。本研究旨在探讨青少年食欲减退与自杀意念和自残的关系。采用自我报告问卷对18250名日本初高中学生（12-18岁）进行了自杀意念或自残与食欲减退相关的调查。失眠，一种先前与自杀风险相关的身体症状，也在分析中得到了控制。结果显示，青少年有自杀意念或自残的比率随自我报告食欲减退程度的增加而显著增加。失眠也有类似的结果。经性别和年龄调整后，有食欲丧失的青少年与没有食欲丧失的青少年相比，自杀意念和自残的比值比分别为5.5和4.1，有失眠的青少年与没有食欲丧失的青少年相比，其比值比分别为5.5和3.5 （p < 0.001）。在调整抑郁/焦虑（一般健康问卷-12评分）后，ORs仍然具有统计学意义。综上所述，青少年自我报告的食欲减退与自杀意念和自残高度相关；报告出现食欲不振或失眠等身体症状的青少年应予以密切关注。(C) 2016 Elsevier Ltd.版权所有。
Suicide is a leading cause of death in adolescents, but detection of its risk is often challenging. Many mental illnesses share the common symptom of appetite loss and it is also known that people who suffer from these illnesses are at greater risk of suicide. However, the relationship between appetite loss and suicide risk has yet to be examined. For adolescents in particular, questions about appetite loss may be easier to answer than sensitive questions regarding mental health. The present study aims to investigate the association of appetite loss with suicidal ideation and self-harm in adolescents. Rates of adolescents with suicidal ideation or self-harm associated with appetite-loss were examined in 18,250 Japanese junior and senior high school students (aged 12-18) using a self-report questionnaire. Insomnia, a physical symptom which has previously been associated with suicide risk, was also controlled for in the analysis. Results showed that rates of adolescents with suicidal ideation or self-harm significantly increased according to the degree of self-reported appetite loss. Similar results were observed for insomnia. Odds ratios (ORs) for suicidal ideation and self-harm were 5.5 and 4.1 for adolescents with appetite loss compared to those without it, and the ORs were 5.5 and 3.5 for those with insomnia compared to those without it, respectively, adjusting for sex and age (p < 0.001). ORs remained statistically significant after adjusting for depression/anxiety (General Health Questionnaire-12 score). In conclusion, self-reported appetite loss was highly associated with suicidal ideation and self-harm in adolescents; adolescents reporting physical symptoms such as loss of appetite or insomnia should be given careful attention.
