title: Different rates of first admissions for psychosis in migrant groups in Paris.
abstract: OBJECTIVE
  The association between migration and psychosis has been reported in the past decades in many European countries. Despite large-scale migration into France, epidemiological data on the incidence of psychosis in this population are lacking. In this study, we compare the incidence rates of first admission for psychosis among natives and first generation migrants.
  
  
  METHODS
  Two-hundred and fifty-eight patients aged 15+ with first admission for psychosis were identified in the catchment area of the 20th district of Paris between 2005 and 2009. Standardised incidence rates and incidence rate ratios were calculated for migrant and native groups.
  
  
  RESULTS
  We found higher rates of admissions for psychosis in the migrant group (IRR 2.9, 95 % CI 0.9-9.8) compared to individuals born in France. Among migrants, incidence was higher in individuals from Sub-Saharan Africa compared to natives (IRR 7.1, CI 95 % 2.3-21.8), whereas the incidence was similar for those from Europe (IRR 1.2, CI 95 % 0.3-5.1) and from North Africa (IRR 1.4, CI 95 % 0.4-5.6).
  
  
  CONCLUSIONS
  Our findings suggest that Sub-Saharan migrants were identified as the most vulnerable migrant group for developing psychosis in France, but additional work is warranted to confirm these trends.
