[Disability due to mental and behavioural disorders in Iceland.].

AIMS
To determine the prevalence of disability in Iceland on December 1st 2002 due to mental and behavioural disorders according to gender, place of residence and marital status and main subcategories.


MATERIAL AND METHODS
The disability register of the State Social Security Institute was used to obtain information on the number, gender, age, place of residence, marital status and main diagnosis of recipients of disability pension. From Statistics Iceland the same information was obtained for the Icelandic population between the age of 16 and 66.


RESULTS
The prevalence of disability due to mental and behavioural disorders was 2.32% for females and 1.98% for males. For males receiving disability pension the proportion having mental disorders as the main cause of disability was larger than for females. Among females the most common cause of disability was mood disorders whereas among males it was schizophrenia, schizotypal and delusional disorders. Most of those with schizophrenia, schizotypal and delusional disorders in Iceland receive full disability pension. The prevalence of disability due to mental and behavioural disorders was significantly higher in the capital region than in the rest of the country. Marriage and registered co-habitation was considerably less common among recipients of disability pension due to mental and behavioural disorders than among the nation in general.


CONCLUSION
The prevalence of disability due to mental and behavioural disorders in the capital region is in excess of what is to be expected from the prevalence of these disorders and from disability in general in Iceland. The relatively high prevalence of disability due to mental and behavioural disorders among males is in line with epidemiological data. The prevalence of disability due to mental and behavioural disorders in Iceland has been rising. This needs to be addressed by improving vocational rehabilitation programs for those suffering from these disorders.
