Abstract OBJECTIVE: The authors synthesize findings of previous studies implicating migration as a risk factor for the development of schizophrenia and provide a quantitative index of the associated effect size. METHOD: MEDLINE was searched for population-based incidence studies concerning migrants in English-language publications appearing between the years 1977 and 2003. Article bibliographies and an Australian […]
Abstract PURPOSE:The EUropean Network of National Schizophrenia Networks Studying Gene-Environment Interactions (EU-GEI) study contains an unparalleled wealth of comprehensive data that allows for testing hypotheses about (1) variations in incidence within and between countries, including by urbanicity and minority ethnic groups; and (2) the role of multiple environmental and genetic risk factors, and their interactions, […]
Abstract: Studied schizophrenia (SCZ) and related disorders in 10 countries (Colombia, Czechoslovakia, Denmark, India, Ireland, Japan, Nigeria, the USSR, the UK, and the US), based on an initial and 1- and 2-yr follow-up examinations of 1,379 patients (aged 15–54 yrs). Early behavioral manifestations of psychotic illness were similar across the geographical centers. 82% of the cases […]
Abstract Background The incidence of psychotic disorders is elevated in some minority ethnic populations. However, we know little about the outcome of psychoses in these populations. Aims To investigate patterns and determinants of long-term course and outcome of psychoses by ethnic group following a first episode. Method ÆSOP-10 is a 10-year follow-up of an ethnically […]
Key Points Question Does the treated incidence of psychotic disorders vary across 17 settings in 6 countries, and to what extent is this explained by individual and catchment area–level risk factors? Findings The overall crude incidence of psychotic disorders in this international multisite incidence study was 21.4 per 100 000 person-years, and after standardization this incidence varied 8-fold […]

Abstract Background There is increasing acceptance of migration as a risk factor for schizophrenia and related disorders; however, the magnitude of the risk among second-generation immigrants (SGIs) remains unclear. Generational differences in the incidence of psychotic disorders among migrants might improve our understanding of the relationship between migration, ethnicity and psychotic disorders. This meta-analysis aimed […]
