Depressive disorders in Europe: prevalence figures from the ODIN study

TLDR

This first ODIN study reports on the epidemiology of depressive disorders in Europe, categorizing sites into high, medium, and low prevalence groups. The study aims to estimate the prevalence of depressive disorders in randomly selected general population samples across five European countries. A cross‑sectional two‑phase community design was used, with the Beck Depression Inventory in Phase 1 and the Schedule for Clinical Assessment in Neuropsychiatry in Phase 2. The combined sample of 8,764 participants yielded an overall prevalence of 8.56 % (95 % CI 7.05–10.37), with 10.05 % in women and 6.61 % in men, highlighting substantial site‑to‑site variation and confirming high prevalence of depressive disorders in Europe.

Abstract

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% Cl 7.05–10.37). The figures were 10.05% (95% Cl 7.80–12.85) for women and 6.61% (95% Cl 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.
