  1. First-contact incidence rate of schizophrenia on Barbados.

    Article - En anglais

    Background The incidence rate for broad schizophrenia among second-generation African-Caribbean people in the United Kingdom has been reported as high.

    Ethnicity migration and psychosocial stressors have been suggested as causal factors.

    Aims To determine the incidence of schizophrenia for the whole population of Barbados using an identical methodology to two previous studies inTrinidad (Bhugra et al, 1996) and London (Bhugra et al, 1997).

    Method A 12-month study of all persons in the 18-54-year age group presenting with a psychosis for the first time was carried out on the population of Barbados.

    Information was collected using World Health Organization screening and measurement instruments.

    Results On an island of just over a quarter of a million, 40 out ofthe 53 patients that metthe inclusion criteriawere categorised as S+ (narrow) schizophrenia, giving an incidence rate of 2.8/10 000 (95% Cl 1.97-3.7).

    The incidence rate for broad schizophrenia was calculated at 3.2/10 000 (95% Cl 2.3-4.1), which is significantly lower than the comparable rate for London's African - Caribbeans of 6.6/10 000 (95% CI 4.5-8.7).

    Conclusions The very high rate for broad schizophrenia among African-Caribbean people in the UK is probably due to environmental factors.
