income inequality by gini-coefficient on suicide death in iran: a review of national data

Background: 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. methods: 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%. results: 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. conclusion: 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
