Researchers in Britain opined that it's the ethnic groups in Britain, who are more prone to suffer from major mental disorders rather than the native Britishers.
African-Caribbean and Black Africans showed increased risk of suffering from psychoses, and schizophrenia according to recent studies conducted by scientists from the Institute of Psychiatry in London.
They found that both women as well as men show and increased risk. Schizophrenia seemed to surface 2.5 times more in whites of other nations six times more likely in Black Africans nine times in African Caribbean people than native Britons.
Dr Paul Fearon, lead author of one of the studies told media that the team studied a section of ethnic groups staying in South east London .The data collected showed a significantly high incidence of psychotic illnesses among the "Afro- Caribbean and Black African people .This was the largest studies that have been done so far related to psychoses among ethnic groups in Britain.
About 400 healthy individuals and nearly 600 patients suffering from with psychosis were part of the study.
The researchers have explained that the study was initiated to understand how effective new measures could be implemented to treat psychoses.
In a second study they also explored reasons that could trigger off such a high incidence of mental illness. They found out that often it is the early separation from parents at a very young age, mostly before the age of 16 that triggered mental illness later in life. Separation from either parent was more prevalent among the ethnic minorities than native Britons.
An early separation creates an ambience of social adversity explained researchers.
Even when other risk factors were taken into account the findings remained the same. The journal Psychological Medicine has published the results of the study.
