Background:
This is the first report on the epidemiology of depressive disorders from the European Outcome of Depression International Network (ODIN) study.
Aims:
To assess the prevalence of depressive disorders in randomly selected samples of the general population in five European countries.
Method:
The study was designed as a cross-sectional two-phase community study using the Beck Depression inventory during Phase 1, and the Schedule for Clinical Assessment in Neuropsychiatry during Phase 2.
Results:
An analysis of the combined sample (n=8.764) gave an overall prevalence of depressive disorders of 8.56% (95% CI 7.05-10.37). The figures were 10.05% (95% CI 7.80-12.85) for women and 6.61% (95% CI 4.92-8.83) for men. The centres fall into three categories: high prevalence (urban Ireland and urban UK), low prevalence (urban Spain) and medium prevalence (the remaining sites).
Conclusions:
Depressive disorder is a highly prevalent condition in Europe. The major finding is the wide difference in the prevalence of depressive disorders found across the study sites.
