Abstract

Background About 13 million people are classified as refugees worldwide, and many more former refugees have been granted citizenship in their new countries. However, the prevalence of post-traumatic stress disorder, major depression, or psychotic illnesses in these individuals is not known. We did a systematic review of surveys about these disorders in general refugee populations in western countries.Methods We searched for psychiatric surveys that were based on interviews of unselected refugee populations and that included current diagnoses of post-traumatic stress disorder, major depression, psychotic illnesses, or generalised anxiety disorder. We did computer-assisted searches, scanned reference lists, searched journals, and corresponded with authors to determine prevalence rates of these mental disorders and to explore potential sources of heterogeneity, such as diagnostic criteria, sampling methods, and other characteristics.Findings 20 eligible surveys provided results for 6743 adult refugees from seven countries, with substantial variation in assessment and sampling methods. In the larger studies, 9% (99% CI 8-10%) were diagnosed with post-traumatic stress disorder and 5% (4-6%) with major depression, with evidence of much psychiatric comorbidity. Five surveys of 260 refugee children from three countries yielded a prevalence of 11% (7-17%) for post-traumatic stress disorder. Larger and more rigorous surveys reported lower prevalence rates than did studies with less optimum designs, but heterogeneity persisted even in findings from the larger studies.Interpretation Refugees resettled in western countries could be about ten times more likely to have post-traumatic stress disorder than age-matched general populations in those countries. Worldwide, tens of thousands of refugees and former refugees resettled in western countries probably have post-traumatic stress disorder.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
