Studying the Prevalence of PTSD in Veterans, Combatants and Freed Soldiers of Iran-Iraq War: A Systematic and Meta-analysis Review.

War as an unpleasant and stressful phenomenon could be the cause of psychiatric disorders. This study aims to collect and compare conducted research to estimate the prevalence of Post-Traumatic Stress Disorder (PTSD) in combatants, veterans, and freed soldiers of the 1980–88 Iran-Iraq war. This study is a case review study in which articles were found using keywords, such as Post-Traumatic Stress Disorder (PTSD), veterans, combatants, captive, soldiers and war in domestic and foreign databases, personal archives, libraries of Iran and Tehran Universities of Medical Sciences and the National Library. The cumulative incidence of PTSD was determined to be 27.8% in veterans, combatants, and freed soldiers. The prevalence of PTSD as seen in civilian and some military studies is less than the values determined in this study. Reasons for this discrepancy may be due to longer durations of exposure and greater numbers of in-the-field missions, multiple traumas, and higher rates of combat exposure, as well as differences in sampling and measurement strategies (e.g. the use of questionnaires instead of clinical interviews).
