Preprints with The Lancet is part of SSRN´s First Look, a place where journals identify content of interest prior to publication. Authors have opted in at submission to The Lancet family of journals to post their preprints on Preprints with The Lancet. The usual SSRN checks and a Lancet-specific check for appropriateness and transparency have been applied. Preprints available here are not Lancet publications or necessarily under review with a Lancet journal. These preprints are early stage research papers that have not been peer-reviewed. The findings should not be used for clinical or public health decision making and should not be presented to a lay audience without highlighting that they are preliminary and have not been peer-reviewed. For more information on this collaboration, see the comments published in The Lancet about the trial period, and our decision to make this a permanent offering, or visit The Lancet´s FAQ page, and for any feedback please contact firstname.lastname@example.org.
Mental Disorders in Refugees: A Systematic Review and Meta-Analysis
22 Pages Posted: 4 Dec 2019More...
Background: The number of refugees is highest since the second world war and on the rise. Many refugees suffer from mental disorders, but exact and up-to-date prevalence estimates and sources of heterogeneity herein (e.g., host continent, length of residency) are not available.
Methods: We undertook a systematic review with meta-analyses to summarize the literature on the prevalence of mood, anxiety, and post-traumatic stress disorder (PTSD) in general refugee populations. We also investigated moderators of prevalence rates. The study protocol was pre-registered at PROSPERO (ID CRD42018100539).
Findings: Systematic searches (final search date August the 3th 2019) yielded 66 eligible publications that reported 150 prevalence estimates (total N = 14,882). Prevalences for diagnosed and self-reported current anxiety were 13 and 42% (95% Confidence Interval [CI] = 8-52%) (P difference < .05), 30% and 40% (95% CI = 23-48%) for diagnosed and self-reported depression, and 29% and 37% (95% CI = 22-45%) for diagnosed and self-reported PTSD. These estimates are substantially higher relative to those reported in non-refugee populations over the globe and to that of populations living in conflict/war settings, both for adult and child/adolescent refugees. Estimates were similar over different home and resettlement areas and independent of length of residence.
Interpretation: Our data indicate a huge and persisting disease burden in refugees around the globe due to poor mental health. Knowing this is relevant for the development of public health policies of host countries. Scalable interventions, tailored for refugees, should become more readily available.
