Abstract

Background: Unpleasant health outcomes are common in deprived communities and have been shown a direct connection between socioeconomic status and wellbeing but, the effect of the socioeconomic status on suicide is currently controversial. This study explored the relationship of the socioeconomic status and addiction and mental disorders in suicide attempts and decomposed inequalities into its determinants to calculating share of contribution to the inequality. Methods: This cross-sectional study recognized 546 suicide deaths and 6818 attempted suicides from 1 Jan 2010 to 31 Dec 2014 in Ilam Province, West of Iran. Inequality measured by concentration index (CI) and decomposing contribution in inequality. All analysis was performed by standard statistical software, Stata (Ver. 11.2). Results: The pooled rate of death in people with suicide attempts was 8.0 and that of having a history of suicide was 5.2. The overall CI for addiction was -0.233 (95 CI= -0.383 to -0.084), and the CI for mental disorders was 0.0006 (95 CI = -0.009 to 0.010). The more amount of contribution to socioeconomic inequality in suicide attempts because of age group of < 25 yr (26), socioeconomic level (23), and marital status (22). Conclusion: Addiction and mental disorders were distributed among suicide attempters unequally and gap between advantaged and disadvantaged attempted suicide confirmed by our results. Addiction prevention-related policies and programmers' should be focus on disadvantaged groups.
