Meta-analysis: Higher rates of psychotic symptoms among ethnic minorities and immigrants

A new meta-analysis of 24 studies found that ethnic minorities are at higher risk than members of the majority to have psychotic experiences (odds ratio = 1.4) and symptoms (odds ratio = 1.4). The risk was highest for minorities from the Maghreb (Northwest Africa) and the Middle East (odds ratio = 3.3) living in Europe, and Hispanics (odds ratio = 2.0)  and blacks (odds ratio = 1.9) in the United States. The authors also reported a heightened risk of delusional symptoms among immigrants (odds ratio = 1.5).

Of course, the researchers suggest discrimination is the cause of these manifestations of mental illness, but whether it's due to social or biological causes (or both) why don't we have folks stay in their home countries? It's better for us, and it might be better for them.
