[目的]了解农村居民自杀死亡率,探讨其死亡原因,为制订干预措施提供科学依据。[方法]对东营市利津县、河口区2004~2005年农村居民自杀死亡情况进行回顾性调查,按1∶1配比进行病例对照研究,探讨自杀危险因素。选择对照的匹配条件是性别相同、年龄相差1~2岁。[结果]利津县、河口区2004~2005年农村居民自杀死亡178例,年均死亡率为21.13/10万,其中男女性分别为21.95/10万、20.31/10万(P>0.05),40~79岁男女性分别为42.55/10万、28.99/10万(P<0.05);随着年龄增长死亡率逐渐升高(P<0.01)。多因素条件Logistic回归分析结果,受教育程度低、有精神疾病、1年内遭遇负性生活事件、既往自杀未遂史者自杀死亡的危险高(OR分别为5.05、24.92、64.17、40.33)。自杀方式为口服农药的占76.97%、自缢占14.04%、其他方式占8.99%;58.99%存在慢性或严重躯体性疾病。[结论]该地区农村居民自杀死亡率较高,中老年男性高于女性,文化程度低、精神和躯体疾患、负性生活事件和既往自杀未遂者自杀死亡的危险高。
[Objective] To understand the suicide rate of rural residents, discuss the causes of their death and provide a scientific basis for formulating intervention measures. [Method] A retrospective survey was conducted on the suicides and deaths of rural residents in Lijin County and Hekou District of Dongying City from 2004 to 2005. Case-control studies were conducted according to the ratio of 1: 1 to investigate the risk factors of suicide. Select the matching conditions are the same sex, the age difference of 1 to 2 years old. [Results] Among all the residents in Lijin County and Hekou District, there were 178 cases of suicide among rural residents from 2004 to 2005, the annual average death rate was 21.13 / 100000, including 21.95 / 100000, 20.31 / 100000 (P> 0.05) The prevalence of male-female at 79 years old was 42.55 / 100000, 28.99 / 100000 (P <0.05). Mortality increased with age (P <0.01). Multivariate Logistic regression analysis showed that there was a high risk of suicide death (OR: 5.05, 24.92, 64.17, 40.33 respectively) as a result of low education, mental illness and negative life events within one year. Suicide means oral pesticides accounted for 76.97%, accounting for 14.04%, other methods accounted for 8.99%; 58.99% of chronic or severe physical illness. [Conclusion] The rural residents in this area have higher suicide rate, higher middle-aged and older men than women, low educational level, high mental and physical illness, negative life events and suicide deaths from previous suicide attempts.
