BACKGROUND: Disasters have undesirable effects on health among individuals such as psychosocial disorders which may lead lead to suicide in some cases. Thus, the present study aimed to measure the rate of suicide death after disasters all over the world. METHODS: In the present meta-analysis study, all of the articles published in English until the end of 2019 were probed in electronic databases such as Web of Science, PubMed, Cochrane Library, Science Direct, PsycINFO, PsycARTICLES, and Google Scholar. Then, the data were imported to STATA ver.13 software and analyzed through fixed- and random-effects models, meta-regression, and Cochrane statistical tests. RESULTS: A total of 11 studies including a sample size of 65495867 were considered. Suicide death rates before and after the disasters were calculated as 13.61 (CI95%: 11.59-15.77) vs. 16.68 (CI95%: 14.5-19:0) among the whole population, 28.36 (CI 95%:11.29-45.43) vs. 32.17 (CI95%: 17.71-46.62) among men, and 12.71 (CI95%: 5.98-19.44) vs 12.69 (CI95%: 5.17-20.21) among women. The rate of suicide death significantly increased in the whole population and men, while no significant difference was reported among women. CONCLUSION: Suicide death rate increases after disasters indicating the destructive impact of this phenomenon on peoples' health. Therefore, implementing supportive and interventional measures is highly suggested after disasters in order to prevent suicide death among the affected people.
