The prevalence of mental disorders in the Greater-Reykjavik area
The purpose of this study was to estimate the prevalence
of mental disorders in a random sample of three age
groups born in 1931,1951 and 1971 and living in the
Greater- Reykjavik Area. From the original sample of
300 in each birth cohort 805 were contacted and asked
to take part in a survey of mental health. Of those 52%
participated. The instrument used for diagnosing mental
disorders was the CIDI-Auto.
The lifetime prevalence of any ICD-10 disorder was found
to be 49.8%. The most frequent diagnoses were Mental
and behavioral disorders due to use of tobacco (23,6%),
Somatoform disorders (19.0%) and Mental and behavioral
disorders due to use of acohol (10.8%).Any anxiety
disorder was found in 14.4% and any mood disorder
in 13.0%. The one-year prevalence for any disorder
was 19.7%, for tobacco use disorder 6.5%, alcohol
use disorder 6%, somatoform disorders 10.3%, anxiety
disorders 5.5% and mood disorders 2.6%. Alcohol use
disorders are more prevalent among men but somatoform
disorders, anxiety disorders and mood disorders among
women.
The prevalence rates of mental disorders found in this
study is the same or lower than rates found in other
comparable studies. There is no indication of an increase
in the rate of mental disorder in lceland.
