The relative contribution of psychosocial and clinical risk factors to suicide among Chinese populations is an important issue. In Hong Kong, this issue requires vigorous examination in light of a 50% increase in suicide rate between 1997 and 2003.
Using a case-control psychological autopsy method, 150 suicide deceased were compared with 150 living controls matched by age and gender. Semi-structured interviews were conducted with the next-of-kin of the subjects. Data were collected on a wide range of potential risk and protective factors, including demographic, life event, clinical and psychological variables. The relative contribution of these factors towards suicide was examined in a multiple logistic regression model.
Six factors were found to significantly and independently contribute to suicide: unemployment, indebtedness, being single, social support, psychiatric illness, and history of past attempts.
Both psychosocial and clinical factors are important in suicides in Hong Kong. They seem to have mediated suicide risk independently. In addition, socio-economic adversities seem to have played a relatively important role in the increasing suicide rate in Hong Kong.
心理社会因素和临床风险因素对中国人群自杀的相对影响是一个重要问题。在香港，鉴于1997年至2003年间自杀率上升了50%，这一问题需要深入研究。
采用病例对照心理解剖方法，将150名自杀死亡者与150名年龄和性别匹配的在世对照者进行比较。对受试者的近亲进行半结构化访谈。收集了广泛的潜在风险和保护因素的数据，包括人口统计学、生活事件、临床和心理变量。在多元逻辑回归模型中检验了这些因素对自杀的相对影响。
发现六个因素对自杀有显著且独立的影响：失业、负债、单身、社会支持、精神疾病和既往自杀未遂史。
心理社会因素和临床因素在香港的自杀事件中都很重要。它们似乎独立介导了自杀风险。此外，社会经济困境似乎在香港自杀率上升中起到了相对重要的作用。
