Associations between attention deficit hyperactivity disorder (ADHD) subtypes and suicidal behaviors remains unclear. The current study explored the prevalence of suicidal behaviors, and its association with ADHD among Chinese medical students.
Five thousand six hundred ninety-three medical college students participated. Symptoms of suicidal behaviors, ADHD, anxiety, depression, tobacco and alcohol use were assessed using online questionnaires.
The prevalence of lifetime suicidal ideation, suicide plans, and suicide attempts among medical college students were 27.5, 7.9 and 14.8% respectively. Participants with ADHD predominantly inattentive type (ADHD-I) had more than fivefold increased odds of suicidal behaviors, the adjusted odds ratios (ORs) of ADHD-I and ADHD combined type (ADHD-C) remained significant after controlling for confounding factors.
ADHD is associated with high risk of suicidal behaviors. ADHD-I and ADHD-C were strongly associated with suicidal behaviors independent of comorbidities. The finding suggests the importance of addressing ADHD symptoms in suicide prevention.
注意缺陷多动障碍(ADHD)亚型与自杀行为之间的关联仍不清楚。本研究探讨了中国医学生自杀行为的发生率及其与 ADHD 的关系。
5693 名医学生参加了这项研究。使用在线问卷评估自杀行为、ADHD、焦虑、抑郁、烟草和酒精使用的症状。
医学生终身自杀意念、自杀计划和自杀企图的发生率分别为 27.5%、7.9%和 14.8%。ADHD 主要注意力不集中型(ADHD-I)的参与者自杀行为的可能性增加了五倍以上,在控制了混杂因素后,ADHD-I 和 ADHD 混合型(ADHD-C)的调整后比值比(OR)仍然显著。
ADHD 与自杀行为的高风险相关。ADHD-I 和 ADHD-C 与自杀行为独立于合并症有很强的关联。这一发现表明,在预防自杀方面,解决 ADHD 症状的重要性。
