Prevalence of and risk factors for mental disorders in refugees

Given the increasing numbers of refugees worldwide, the prevalence of their mental disorders is relevant for public health. Prevalence studies show that, in the first years of resettlement, only post-traumatic stress disorder (PTSD) rates are clearly higher in refugees than in host countries' populations. Five years after resettlement rates of depressive and anxiety disorders are also increased. Exposure to traumatic events before or during migration may explain high rates of PTSD. Evidence suggests that poor social integration and difficulties in accessing care contribute to higher rates of mental disorders in the long-term. Policy and research implications are discussed
