Global burden of post-traumatic stress disorder and major depression in countries affected by war between 1989 and 2019: a systematic review and meta-analysis

ObjectiveExtensive research has demonstrated high prevalences of post-traumatic stress disorder (PTSD) and major depression (MD) in war-surviving populations. However, absolute estimates are lacking, which may additionally inform policy making, research and healthcare. We aimed at estimating the absolute global prevalence and disease burden of adult survivors of recent wars (1989–2019) affected by PTSD and/or MD.MethodsWe conducted a systematic literature search and meta-analysis of interview-based epidemiological surveys assessing the prevalence of PTSD and/or MD in representative samples from countries with a recent war history (1989–2019). Drawing on the war definition and geo-referenced data of the Uppsala Conflict Database Programme and population estimates of the United Nations for 2019, we extrapolated the meta-analytic results to absolute global numbers of affected people. Drawing on disability-adjusted life years (DALYs) data of the Global Burden of Diseases Study 2019, we further calculated the PTSD-associated and MD-associated DALYs.ResultsTwenty-two surveys (N=15 420) for PTSD, 13 surveys for MD (N=9836) and six surveys on the comorbidity of PTSD and MD (N=1131) were included. Random effects meta-analyses yielded point prevalences of 26.51% for PTSD and 23.31% for MD. Of those affected by PTSD, 55.26% presented with comorbid MD. Prevalence rates were not significantly associated with war intensity and length, time since war, response rate or survey quality. The extrapolation yielded 316 million adult war-survivors globally who suffered from PTSD and/or MD in 2019. War-survivors were almost exclusively living in low/middle-income countries (LMICs) and carried a burden of 3 105 387 and 4 083 950 DALYs associated with PTSD and MD, respectively.ConclusionsSince LMICs lack sufficient funding and qualified professionals to provide evidence-based psychological treatments for such large numbers of affected people, alternative and scalable strategies using existing resources in primary care and communities are required. Research is required to assist upscaling.

The Impact of War-Related Stress on Coronary Artery Disease Severity in War Survivors: A SYNTAX Study

Background: Due to the strong relationship between stress and heart disease, particularly acute myocardial infarction (MI), this study investigated the complexity of coronary artery disease (CAD) among Syrian refugee patients referred to Jordan University Hospital and its relation to war-related stressors. Methods: This is a retrospective study that utilized the SYNTAX I score in order to evaluate all Syrian refugees that underwent coronary artery catheterization at Jordan University Hospital during the period between May of 2014 and December of 2017. Results: There was a significant association between war-related stressors and high SYNTAX score (SX score), thus indicating a higher complexity of CAD in Syrian war survivors with higher stress scores. The strongest war-related correlation was observed with crossing green-lines, in which Syrian refugee patients who had crossed such lines had significantly higher SYNTAX scores. Regression analysis demonstrated that war stressors were positive predictors of increased SYNTAX scores even when adjusted for conventional CAD risk factors. Surprisingly, none of the CAD risk factors were significantly associated with SYNTAX score. Conclusion: Our findings suggest that exposure to multiple war-related stressors may increase the complexity and severity of CAD in Syrian war survivors. Thus, special attention, efforts, and resources should be allocated to screen for such vulnerable patients in order to provide them with the appropriate healthcare.

Assessing exposure to war-related traumatic events in older Vietnamese war survivors

Background Though studies measuring war-related stressors and resultant trauma among U.S. military veterans are abundant, few studies address how wartime stressors affect military veterans native to warzones. Even fewer assess the stress exposure and resulting trauma experienced by Vietnamese civilians. This study aimed to construct a scale to quantify wartime stress exposure that is relevant for civilians and military veterans who survived the American War in Vietnam. Methods The study analyzed data from a novel source, the Vietnam Health and Aging Study, which surveyed older men and women residing in central and northern Vietnam. We used a combination of exploratory and confirmatory factor analysis with posthoc tests of reliability and validity to derive measures for assessing exposure to war-related traumatic events. Results We found that a mix of exposure to death, combat, inhospitable living conditions, and forced displacement comprises the traumatic events that potentially contribute to posttraumatic stress disorder and other mental health problems. However, the particular mix of stressful experiences constituting war trauma differs for civilians, veterans of the formal military, and former members of paramilitary organizations. Conclusions These findings suggest the need for distinct but parallel approaches to measuring war-related stressors for populations of veterans and civilians exposed to war in their home countries and the need for greater public attention to the potential lingering trauma of noncombatants.

A Dual-Model of Posttraumatic Stress and Posttraumatic Growth in a Community Sample of Female Conflict-Related Sexual Violence Survivors from Bosnia and Herzegovina

Background: Posttraumatic stress disorder (PTSD) and posttraumatic growth (PTG) are known psychological outcomes that can co-occur in the aftermath of a traumatic event. However, it is less clear how these outcomes interact – particularly for female survivors of conflict-related sexual violence (CRSV) – and to what extent intermediary factors play a role in this relationship.<br/> Methods: In a sample of 192 war survivors from Bosnia & Herzegovina (n = 104 experienced CRSV, n = 88 did not), a structural equation model (LISREL 8.8) tested CRSV as a traumatic event, 'positive reinterpretation' (as a strategy of approach coping) and 'behavioural disengagement' (as a strategy of avoidance coping), and PTSD and PTG as psychosocial outcomes. A difference in the mechanisms by which PTG and PTSD interact in the two subgroups was hypothesised, given the differences in the nature of the trauma they experienced.<br/> Results: Through multiple indirect relationships, results showed that CRSV survivors respond to their trauma with both PTSD and PTG, suggesting a dual PTSDPTG mechanism. As for coping strategies, positive reinterpretation predicted greater PTG, and behavioural disengagement predicted greater PTSD. In the sample of nonsexual violence survivors, positive reinterpretation also remained a significant predictor of PTG.<br/> Conclusions: Positive reinterpretation as a coping strategy appears to be a stable characteristic that independently predicts PTG, irrespective of trauma type. Mental health professionals should take into account this mechanism when addressing the needs of CRSV survivors, but also war survivors more generally. Reframing traumatic events and post-trauma sequalae during treatment could lead to PTG and enhance recovery.

Up from the farm: a global microhistory of rural Americans and Africans in the First World War

Were the effects of First World War truly similar globally? A comparison of how the conflict was perceived by two extremely different groups of rural people – southern Americans of the Jackson Purchase region of far western Kentucky and Africans in the small British Protectorate of Nyasaland in south central Africa – makes their microhistories significant rather than trivial by placing them a global context. In the early twentieth century, both groups were not only rural, but removed, decidedly disconnected from each other. Yet, drawing on documentary evidence, especially interviews with the last generation of First World War survivors in both regions, offers a significant perspective on how similar their experiences actually became in the crucible of a global war. The call to arms, their recruitment and resistance to service, combat adversities and cultural experiences, post-war disillusionments and triumphs, and especially the economic consequences of their war provide penetrating insights into the wide-ranging ordeals and opportunities that this first truly global event offered peoples worldwide.
