Epidemiology has identified violence as a major worldwide public health concern. Suicide is classified as violence. This study analyzes the association between suicide and socio-demographic factors. The methodological design was ecological, using correlation techniques and backward multiple linear regression. Normality of the residuals in the final model was analyzed. Proportional mortality in relation to total deaths was identified as the best outcome for modeling (R(2) = 0.41). The resulting variables were: % Pentecostal religion, % single marital status in the population over 10 years of age, mean years of schooling, altitude of the municipality, % homes without latrines, % population over 10 years of age working in the educational sector, and % population over 10 years with per capita earnings up to one minimum wage. All these variables were statistically significant at 5%. The results support the idea of the influence of extrinsic causal factors in determination of suicide.
流行病学已将暴力确定为全球主要的公共卫生问题。自杀被归类为暴力行为。本研究分析了自杀与社会人口因素之间的关联。方法设计为生态学研究，采用相关技术和向后多元线性回归。分析了最终模型中残差的正态性。与总死亡人数相关的比例死亡率被确定为建模的最佳结果（R(2) = 0.41）。得出的变量包括：五旬节派宗教信仰比例、10岁以上人口中的单身婚姻状况比例、平均受教育年限、市镇海拔、无厕所家庭比例、10岁以上在教育部门工作的人口比例以及10岁以上人均收入不超过一个最低工资的人口比例。所有这些变量在5%的水平上均具有统计学意义。结果支持外在因果因素在自杀决定中具有影响这一观点。
