Most Common Methods of Suicide in Eastern Mediterranean Region of WHO: A Systematic Review and Meta-Analysis

Abstract

The aim of this study is to determine the frequency of various methods of suicide in Eastern Mediterranean Region by a systematic review and meta-analysis. All published articles in international database were systematically searched before September 2011. In order to analyze the data we used STATA, ver.10 software. We reported proportions with standard errors (SE) for single studies and pooled estimates for proportions of different suicidal methods based on random model meta-analysis. We included 19 articles in the final analysis. The pooled proportion of hanging, self-immolation, and poisoning were 39.7% (95% CI: 26.8%-52.7%), 17.4% (95% CI: 10%-24.8%), and 20.3% (95% CI: 14%-26.5%) respectively. Self-immolation and poisoning were gender dependent and hanging was country dependent in the meta-regression method. We found out that the 3 most common methods of suicide in EMR are hanging, poisoning, and self-immolation. These methods are estimated to account for 77.4% of all methods of suicide in EMR.
