作者调查了 15-34 岁中国农村自杀者的精神障碍患病率和分布情况。他们假设精神疾病是该人群自杀的危险因素，并且女性精神疾病的患病率低于男性。在这项病例对照心理尸检研究中，我们对 392 名自杀受害者和 416 名活着的对照对象进行了面对面访谈，从代理线人那里收集信息。使用中文版 DSM-IV 结构化临床访谈对死亡或访谈时的五类 DSM-IV 精神障碍（情绪障碍、精神分裂症和其他精神障碍、物质使用障碍、焦虑障碍和其他 I 轴障碍）进行评估。还评估了社会人口统计学变量、社会支持和生活事件。目前自杀受害者的精神疾病患病率为 48.0%，对照组为 3.8%。在自杀受害者中，男性比女性更容易患精神疾病（55.1% 比 39.3%）。在调整社会人口特征后，发现精神疾病和自杀之间存在很强的关联。其他风险因素包括教育水平较低、目前未婚、社会支持水平较低以及有近期和长期生活事件史。在精神疾病和较低水平的社会支持之间观察到了相加的相互作用。尽管精神疾病是自杀的一个重要危险因素，但与中国和西方的其他人群相比，自杀的中国农村年轻人（尤其是女性）的发病率较低。
The authors examined the prevalence and distribution of mental disorders in rural Chinese 15–34 years of age who committed suicide. They hypothesized that mental illness is a risk factor for suicide in this population and that the prevalence of mental illness is lower in females than in males. In this case-control psychological autopsy study, face-to-face interviews were conducted to collect information from proxy informants for 392 suicide victims and 416 living comparison subjects. Five categories of DSM-IV mental disorders (mood disorders, schizophrenia and other psychotic disorders, substance use disorders, anxiety disorders, and other axis I disorders) at the time of death or interview were assessed using the Chinese version of the Structured Clinical Interview for DSM-IV. Sociodemographic variables, social support, and life events were also assessed. The prevalence of current mental illness was 48.0% for suicide victims and 3.8% for comparison subjects. Among suicide victims, mental illness was more prevalent in males than in females (55.1% compared with 39.3%). A strong association between mental illness and suicide was observed after adjustment for sociodemographic characteristics. Other risk factors included having a lower education level, not being currently married, having a lower level of social support, and having a history of recent and long-term life events. Additive interactions were observed between mental illness and lower level of social support. Although mental illness is a strong risk factor for suicide, it is less prevalent among rural Chinese young people who committed suicide, particularly females, in comparison with other populations in China and in the West.
