| Title | Psychoses, ethnicity and socio-economic status. | | Author(s) | Kirkbride JB, Barker D, Cowden F, Stamps R, Yang M, Jones PB, Coid JW | | Institution | University Department of Psychiatry, Addenbrooke's Hospital, Hills Road, Cambridge, UK. jbk25@cam.ac.uk | | Source | Br J Psychiatry 2008 Jul; 193(1):18-24. | | Abstract | BACKGROUND: Consistent observation of raised rates of psychoses among Black and minority ethnic (BME) groups may possibly be explained by their lower socio-economic status.
AIMS: To test whether risk for psychoses remained elevated in BME populations compared with the White British, after adjustment for age, gender and current socio-economic status.
METHOD: Population-based study of first-episode DSM-IV psychotic disorders, in individuals aged 18-64 years, in East London over 2 years.
RESULTS: All BME groups had elevated rates of a psychotic disorder after adjustment for age, gender and socio-economic status. For schizophrenia, risk was elevated for people of Black Caribbean (incidence rate ratios (IRR)=3.1, 95% CI 2.1-4.5) and Black African (IRR=2.6, 95% CI 1.8-3.8) origin, and for Pakistani (IRR=3.1, 95% CI 1.2-8.1) and Bangladeshi (IRR=2.3, 95% CI 1.1-4.7) women. Mixed White and Black Caribbean (IRR=7.7, 95% CI 3.2-18.8) and White Other (IRR=2.1, 95% CI 1.2-3.8) groups had elevated rates of affective psychoses (and other non-affective psychoses).
CONCLUSIONS: Elevated rates of psychoses in BME groups could not be explained by socio-economic status, even though current socio-economic status may have overestimated the effect of this confounder given potential misclassification as a result of downward social drift in the prodromal phase of psychosis. Our findings extended to all BME groups and psychotic disorders, though heterogeneity remains. | | Language | eng | | Pub Type(s) | Journal Article
