为预防自杀行为 ,并为制定必要的可行的干预措施提供科学的依据 ,利用在山东某地区调查的病例 -对照研究资料和随访研究资料 ,应用多因素Logistic回归模型进行分析 ,寻找影响自杀未遂的危险因素。结果显示 :自杀未遂行为的发生与急性应激强度大、患精神病和冲动性人格特征呈正相关 ;与生命质量和家庭亲密度呈负相关。研究提示 :①负性生活事件是农村人群自杀未遂最重要的危险因素 ,其次是患精神疾病 ;②冲动性人格特征也是自杀未遂重要的独立危险因素之一 ;③我国农村人群不同于西方国家的“精神病自杀模式” 。

In order to prevent suicide behavior and propose a comprehensive strat egy for suicide prevention, a cases-control study and then follow-up study in a rural population were conducted. The data were analyzed by Logistic model so as to look for the risk factors of suicide attempts. The results showed that suicid e attempts were significantly positive associated with recent stress in life eve nts, mental illness, higher scores for lifetime aggression and impulsivity while suicide attempts were negative associated with higher scores for the quality of life and higher scores for the family cohesion.
