Abstract

Objective: We aimed to identify subgroups of suicide risk and their characteristics among Korean adults.

Methods: We used data from the National Mental Health Survey of Korea 2021. Participants were 5,511 adults aged 18-79 years. Latent class analysis was conducted to identify patterns of suicide risk using suicidal thoughts, plans, attempts, and self-harm. Sociodemographic and health-related characteristics according to the subtype of suicide risk were compared.

Results: Suicide risk was classified into three latent classes: low suicide risk (89.5%, Class 3 [C3]), high suicidal ideation and low suicidal behavior (8.7%, Class 2 [C2]), and high suicidal thoughts and behavior (1.8%, Class 1 [C1]). Risk factors associated with C1 and C2 were the absence of a spouse, low educational and economic status, and unstable occupational status. C1 and C2 had more physical and psychological problems than did C3. Prevalence of mental disorders and mental health service use were higher in C1 than in C2.

Conclusion: Suicide risk types have different demographic, physical health-related, and mental health-related characteristics. Therefore, a focused and individualized suicide preventive strategy should be implemented.

韩国成人自杀风险的潜在亚型和特征。

目的：我们旨在确定韩国成年人的自杀风险亚群及其特征。方法：我们使用的数据来自2021年韩国国家心理健康调查。参与者是5511名年龄在18-79岁之间的成年人。进行潜在类别分析，通过自杀想法、计划、企图和自残来识别自杀风险模式。比较各亚型自杀风险的社会人口学特征和健康相关特征。结果：自杀风险分为低自杀风险（89.5%，第3类[C3]）、高自杀意念和低自杀行为（8.7%，第2类[C2]）和高自杀意念和行为（1.8%，第1类[C1]）三个潜在类别。与C1和C2相关的危险因素是没有配偶，低教育和经济地位，以及不稳定的职业状态。C1和C2比C3有更多的生理和心理问题。C1区精神障碍患病率和精神卫生服务使用率高于C2区。结论：自杀风险类型具有不同的人口学、生理健康和心理健康特征。因此，应实施有针对性和个性化的自杀预防策略。
