Whether a low body mass index (BMI) is directly associated with a high risk of suicidal ideation or self-harming behavior in adolescents is still inconclusive. This study has, therefore, evaluated the relevance of BMI to suicidal ideation and self-harming behavior after controlling for body weight perception (BWP) and other potential confounding factors. BMI, BWP, suicidal ideation, and self-harming behavior were all assessed using a self-report questionnaire administered to 18,104 Japanese adolescents. Potential confounding factors were also evaluated. The data were then analyzed using bivariate and multivariate logistic regression. Low BMI was associated with suicidal ideation and deliberate self-harm when controlling for sex, age, drug use, emotional distress, and BWP. Low BMI may be an independent risk factor for suicidal ideation and deliberate self-harming behavior in Japanese adolescents.
低体重指数（BMI）是否与青少年自杀意念或自我伤害行为的高风险直接相关仍无定论。因此，本研究在控制体重感知（BWP）和其他潜在混杂因素后，评估了BMI与自杀意念和自我伤害行为之间的相关性。BMI、BWP、自杀意念和自我伤害行为均通过对18104名日本青少年进行的自我报告问卷进行评估。还评估了潜在的混杂因素。然后使用双变量和多变量逻辑回归分析数据。在控制性别、年龄、药物使用、情绪困扰和BWP后，低BMI与自杀意念和故意自我伤害有关。低BMI可能是日本青少年自杀意念和故意自我伤害行为的独立危险因素。
