A Norwegian Psychiatric Epidemiological Study

Abstract

Epidemiological data for Oslo show that the lifetime and 12-month prevalences of mental disorder are quite high, with alcohol abuse/dependence and major depression particularly frequent. The rates for women are higher than those for men for all diagnostic categories, except for alcohol and drug abuse/dependence.

Social phobia and number of social fears, and their association with comorbidity, health-related quality of life and help seeking

“…The 12-month prevalence rate (4.8%) in the present study was rather lower than the previous findings (6.7-7.9%) conducted in Norway, Canada and United States of America which used DSM-III-R criteria and the CIDI [11,17,21,24]. This may be clarified by two explanations.…”

“…Social phobia is a highly prevalent disorder [8,10,11,13,16,17,20,24], which is associated with huge loss in quality of life, [34,39] enormous economic costs, [25] high levels of service use, [23,28,33], serious functional impairments in the areas of education, social and occupational domains [8,19,28], and high comorbidity rates with other anxiety and mood disorders [7,18].…”

Patterns of psychiatric diagnoses in inpatient and outpatient psychiatric settings in Saudi Arabia

“…Comparable findings were reported in the U.S. National Comorbidity study, which observed that women had elevated rates of affective disorders and anxiety disorders whereas men had elevated rates of substance-use disorders and antisocial personality disorder 27 . Also, similar findings were reported in European studies 28,41 and a local primary care study 42 . Although the evidence of gender differences in the risk of schizophrenia is inconclusive, a meta-analysis observed the that men have a higher incidence and morbidity risk than women 43 .…”

“…However, worldwide, anxiety and depressive disorders are the two most common classes of mental disorders in the community, as high as 18% for anxiety disorders and 9% for mood disorders 27,28 . The prevalence of all psychotic disorders is approximately 3% (0.87% for schizophrenia and 0.24% for bipolar I disorder) 29 .…”

Assessing the heritability of anorexia nervosa symptoms using a marginal maximal likelihood approach

“…Both the paperand-pencil version of CIDI and the computerized version identical to the one used in this investigation have previously been used in Norway (Kringlen, Torgersen, & Cramer, 2001;Landheim, Bakken, & Vaglum, 2003). …”
