IntroductionResearch has established that there are high rates of first episode psychosis (FEP) in immigrant populations. These findings could indicate that socio-environmental risk factors, such as individual social class, social capital, early trauma, life events, neighborhood deprivation could be relevant in explaining the differences in incidence rates observed between migrants and natives, following the socio-developmental model of Morgan et al. (2010). Some preliminary results also indicate that migration history itself versus ethnicity could implicate higher risk of the onset of psychotic disorders.AimsTo present preliminary findings from the EUGEI European Network of National Schizophrenia Networks Studying Gene Environment Interactions study.MethodsPopulation based FEP incidence/case control study. Comparison of the incidence rate of FEP and of the distribution of several risk factors (e.g. substance abuse, neighborhood deprivation, urbanicity and trauma) in natives and migrants in different countries across Europe.ResultsPreliminary results of the EUGEI study will be discussed in comparison with previous evidences.ConclusionThe EUGEI study allows a deeper understanding of the excess of FEP found among migrants in Europe.Disclosure of interestThe authors have not supplied their declaration of competing interest.
