Schizophrenia overdiagnosed in black people by 9 times in one significant UK study

I thought the overdiagnosis rate for black men was 3x or 9x. I've found a reference for the 9x figure. It's the AESOP study which was cited in the New Horizons strategy consultation document which also noted this overdiagnosis rate doesn't happen in the West Indies.

Fuck. What the hell is going on in the UK? This overdiagnosis problem is beyond biomedical cause. It's this sort of shit which gets psychiatry accused of racism.

There's something like a 2 times factor associated with migration (though this may not be causal, i.e. the people who migrate may have more flighty tendencies or more wander lust which may correlate with schizophrenia though the trauma which many migrants in the UK may also cause schizophrenia to express) which might ameliorate the charge of institutionalised racism. There may be other factors too however this is stil a startling figure.

9 fucking times more in this significant study. But not in the West Indies...

Variation in incidence and ethnicity

"
Many previous studies have found high rates of schizophrenia and other psychoses in the African-Caribbean population in the UK. However, many of these studies have been methodologically limited, and it is not known whether rates are elevated in other minority groups, including White migrants. We found that the overall incidence rate of psychosis in London was over twice that of Nottingham or Bristol. We found remarkably high rates for schizophrenia and mania in both African-Caribbeans. For example, schizophrenia was 9 times more common in African Caribbeans and 6 times more common in Black Africans than in white British people. Moreover, manic psychosis was 8 times more common in African-Caribbeans and 6 times more common in Black Africans than in white British. These findings held true for both men and women and were evident across all age groups.
