Question  Is the incidence of non–affective psychosis higher among refugees compared with the native population and nonrefugee migrants in a host country?

Findings  In this systematic review and meta-analysis of 9 studies, refugees were at a higher relative risk of developing non–affective psychoses compared with the native population and nonrefugee migrants. In studies with a low risk of bias, the relative risk increased statistically significantly to 1.39 for refugees compared with nonrefugee migrants and to 2.41 for refugees compared with the native population; available evidence was limited to Western host countries only.

Meaning  Refugee experience may represent an independent risk factor in non–affective psychosis in migrants, which suggests a need for psychiatric prevention strategies and outreach programs for this group.
