This is the first community-based epidemiological study examining the prevalence of suicidal behaviors, their transitional pathways, and their relationship with mental disorders in metropolitan China.
Suicidal behaviors, including ideation, plans, and attempts were assessed by face-to-face household interviews among 5201 respondents in Beijing and Shanghai in 2001-2002. Lifetime prevalence and risk factors were examined using multivariate discrete-time survival models.
The lifetime prevalence estimates of suicidal ideation, plans, and attempts were 3.1%, 0.9%, and 1.0% respectively. Among suicide ideators, the conditional probability of ever making a plan and an attempt was 29.5% and 32.3% respectively. Progression from ideation to plan and attempt was the highest during the first year after onset. Suicide attempt was predicted by young adulthood, being unmarried, recent onset of ideation and plan, and the presence of mental disorders, especially mood disorder.
Suicidal behaviors in metropolitan China exhibit a low prevalence and an epidemiological profile resembling that found in Western countries.
这是中国大城市地区第一项基于社区的流行病学研究，旨在调查自杀行为的患病率、其转变途径以及与精神障碍的关系。
2001年至2002年期间，通过对北京和上海的5201名受访者进行面对面的家庭访谈，评估自杀行为，包括自杀意念、自杀计划和自杀未遂情况。使用多变量离散时间生存模型检查终生患病率和风险因素。
自杀意念、自杀计划和自杀未遂的终生患病率估计分别为3.1%、0.9%和1.0%。在有自杀意念者中，曾制定自杀计划和实施自杀未遂的条件概率分别为29.5%和32.3%。从意念到计划再到未遂的进展在发病后的第一年最高。年轻成年、未婚、近期出现意念和计划以及存在精神障碍，尤其是情绪障碍，可预测自杀未遂。
中国大城市地区的自杀行为患病率较低，其流行病学特征与西方国家相似。
