Socioeconomic Inequality in Self-immolation, between Genders; Oaxaca-Blinder Decomposition, Results of Registration-Based Suicide Data

Abstract

<strong>Objective:</strong> To assess the important socio-demographic inequalities in self-immolation in between genders.<br /> <strong>Methods:</strong> A cross-sectional study, 2011 to 2016, was conducted. A total of 540 completed suicides were recruited to the study. Data were collected by systematic registration suicide data (SRSD) and Legal Medicine Organization (LMO). The concentration index (CI) was used to determine the inequality. The inequality line was decomposed to find out the main sources of inequality in self-immolation between genders by Oaxaca-Blinder approach.<br /> <strong>Results:</strong> The mean ratio of self-immolation was 21.8% among completed suicides. The decreasing trend was found in self-immolations during 2011-2016 (z = -2.07, <em>p</em> = 0.039), the mean rate in six years, was 2.98 per 100.000 populations. Unemployment −.043 (−.07, −0.01), married subject's −.016 (−.03, −0.00) and low educational level −.005 (−.01, −0.00) were the main inequality source in females compared to males.<br /> <strong>Conclusion:</strong> Our results suggest that despite the incidence decreasing in self-immolation within 6 years of study period, the inequality was detected in self-immolation. The main socio-demographics in inequalities were lower educational level, married persons and unemployment that prevention programs should be more concentrated in females to a decrease of inequality in self-immolation.
