The current study investigated the relationship of suicide and homicide rates internationally. WHO database mortality data for 82 countries concerning suicide, homicides, and cancer and traffic accidents as controls were used. The analysis included Pearson correlation and multiple linear regression analysis. Worldwide homicidal rates explained 55.42%, 43.86% and 41.7% of male and 22.0%, 22.14% and 13.25% of female suicides for 2000, 2005 and 2010 respectively. In Europe there was a positive correlation between male suicide rates and all homicide rates including homicide rates in both genders, in male victims, and in female victims. In America there is no significant correlation. In Asia there is a significant correlation of male suicidal rates only with homicide rates of female victims. We observed marked and interesting differences in the pattern of association between Europe and the Americas. Overall the current paper suggests that at least in some human populations, suicidality and homicidality share common etiopathogenetic substrates and could be triggered by the same internal or external events or might develop based on common genetic background. Empirically it has been suggested that suicide is related to higher living standards while murder is related to poor quality of life and lower living standards.
本研究调查了国际上自杀率和凶杀率之间的关系。使用了世界卫生组织（WHO）数据库关于自杀、凶杀以及癌症和交通事故的死亡率数据作为对照。分析包括皮尔逊相关分析和多元线性回归分析。2000 年、2005 年和 2010 年，全球凶杀率分别解释了男性自杀率的 55.42%、43.86%和 41.7%，以及女性自杀率的 22.0%、22.14%和 13.25%。在欧洲，男性自杀率与包括两性凶杀率、男性受害者凶杀率和女性受害者凶杀率在内的所有凶杀率之间存在正相关。而在美洲则没有显著相关性。在亚洲，男性自杀率仅与女性受害者凶杀率之间存在显著相关性。我们观察到欧洲和美洲之间关联模式存在显著且有趣的差异。总体而言，本研究表明，至少在某些人群中，自杀行为和凶杀行为可能具有共同的病因学基础，可能由相同的内部或外部事件引发，或者可能基于共同的遗传背景发展。从经验上看，有观点认为自杀与较高的生活水平有关，而凶杀则与较差的生活质量和较低的生活水平有关。
