  1. Increased incidence of psychotic disorders in migrants from the Caribbean to the United Kingdom.

    Article - En anglais

    Background

    Several studies have replicated the finding of increased incidence of schizophrenia an related psychoses in first and second generation migrants from the Caribbean.

    The finding ha remained consistent in studies employing different methods, but concern has been expressed abou indirect methods of calculating the population at risk.

    This study aims to overcome these short comings.

    Method

    A further prospective study was undertaken in Nottingham assembling an inception cohor of psychotic patients (N=168) presenting from a defined catchment area.

    The 1991 census, which includes codings for self-ascribed ethnic origin, was used to calculate the denominator, employing correction factors for potential under-enumeration.

    Case-ascertainment was based upon all servic contacts and subjects had in-depth assessments including the SCAN.

    Collateral history was obtained from informants.

    Results

    Subjects born in the Caribbean, or who had one or both parents born in th Caribbean, had a greatly elevated risk (incidence ratios above 7) for all psychotic disorders and fo ICD-10 (DCR) - defined F20 Schizophrenia.

    Conclusions

    The size of the increase and the methodological safeguards employed support the validit of this now highly replicated finding.

    A personal or family history of migration from the Caribbean is a major risk factor for psychosis ; the consistency of this finding justifies a systematic evalua tion of potential aetiological factors. (...)
