BACKGROUND/PURPOSE: Suicide is a huge global health burden. High suicide rates with a low prevalence of major depressive disorder were reported in East Asia. This study aimed to investigate the prevalence of suicidal behaviors in relation to the demographic characteristics and major depressive disorder in Taiwan.
This study was based on the Taiwan Psychiatric Morbidity Survey, conducted between 2003 and 2005, a survey of common psychiatric disorders in a nationally representative sample of non-institutionalized civilians aged 18 or above. Demographic data, major depressive disorder, and suicidal behaviors were ascertained by a face-to-face interview using the paper version of the World Mental Health Survey Composite International Diagnostic Interview.
According to the total sample of 10,135 participants, the lifetime prevalence of suicidal ideation, plans and attempts was 7.52% (S.E = 0.46%), 1.31% (S.E. = 0.16%) and 1.29% (S.E. = 0.16%), respectively. Among suicide ideators, the conditional probability of making a suicide plan was 17.39% (S.E. = 1.92%), and a suicide attempt 17.16% (S.E. = 2.15%). Age ≤ 40, female sex, and major depressive disorder were related to a higher risk of suicidal behaviors in the general population; the former two were associated with further developing suicide attempts and the latter one developing plans among ideators.
Despite low prevalence, major depressive disorder remained a significant risk factor for suicidal behaviors in Taiwan.
背景/目的：自杀是一个全球性的重大健康负担。东亚地区报告的自杀率较高，但重度抑郁症的患病率较低。本研究旨在调查与人口统计学特征和台湾地区重度抑郁症相关的自杀行为的患病率。
本研究基于 2003 年至 2005 年进行的台湾精神疾病发病率调查，这是一项针对 18 岁及以上非住院平民的常见精神障碍的全国代表性样本调查。人口统计学数据、重度抑郁症和自杀行为通过使用纸质版世界精神健康调查综合国际诊断访谈的面对面访谈来确定。
根据 10135 名参与者的总样本，有自杀意念、计划和尝试的终身患病率分别为 7.52%（标准误=0.46%）、1.31%（标准误=0.16%）和 1.29%（标准误=0.16%）。在有自杀意念的人群中，制定自杀计划的条件概率为 17.39%（标准误=1.92%），自杀尝试的条件概率为 17.16%（标准误=2.15%）。年龄≤40 岁、女性和重度抑郁症与一般人群中自杀行为的风险增加相关；前两者与自杀意念者进一步发展自杀尝试有关，后者与制定自杀计划有关。
尽管患病率较低，但重度抑郁症仍是台湾自杀行为的一个重要危险因素。
