Research in source of inequality and enhance of knowledge can be reducing the inequalities in the coming decades. Therefore, we aimed to ascertain effects of income inequality measured by Gini-coefficient to death from suicide in Iran.
This is an ecological study on the relation of Gini-coefficient and suicide death in Iran. Data were obtained from Iranian Urban and Rural Household Income for Gini-coefficient and Expenditure Survey and Iranian Forensic Medicine Organization for suicide. Concentration Index was used to determine of inequality by Gini-coefficient in suicide death and prediction model was applied by Stata software. Significant level considered less than 5%.
A Gini-coefficient between 0.2523 and 0.3755 (mean, 0.3092) was observed. The overall concentration index CI was -0.10 (95% CI= -0.19 to -0.01), therefore our results confirmed a positive inequality in incidence suicide rate result from income inequality in Iran.
Our results showed a positive inequality due to Gini-coefficients in suicide death. This study could be a start for investigation of inequality source in geographical units and at the individual level in all provinces.
对不平等根源的研究以及知识的增进有望在未来几十年减少不平等现象。因此，我们旨在确定用基尼系数衡量的收入不平等对伊朗自杀死亡的影响。
这是一项关于伊朗基尼系数与自杀死亡关系的生态学研究。数据来自伊朗城乡家庭收入与支出调查中的基尼系数数据，以及伊朗法医组织提供的自杀数据。使用集中指数来确定自杀死亡中基尼系数造成的不平等情况，并通过Stata软件应用预测模型。显著性水平设定为小于5%。
观察到基尼系数在0.2523至0.3755之间（均值为0.3092）。总体集中指数CI为 -0.10（95%CI = -0.19至 -0.01），因此我们的结果证实了伊朗收入不平等导致自杀率存在正向不平等。
我们的结果显示了基尼系数导致自杀死亡存在正向不平等。本研究可作为调查所有省份地理区域和个体层面不平等根源的开端。
