Size and burden of depressive disorders in Europe

Abstract

We review epidemiological studies of depression in Europe. Community surveys are essential. Methodological differences in survey methods, instruments, nuances in language and translation limit comparability, but consistent findings are emerging. Western European countries show 1 year prevalence of major depression of around 5%, with two-fold variation, probably methodological, and higher prevalences in women, the middle-aged, less privileged groups, and those experiencing social adversity. There is high comorbidity with other psychiatric and physical disorders. Depression is a major cause of disability. Incidence has been less studied and lifetime incidence is not clear, with longitudinal studies required. There is pressing need for prevalence studies from Eastern Europe. The considerable differences in health care systems among European countries may impact on proportions of depressives receiving treatment and its adequacy, particularly in the key area of primary care, and require further study. There is a need for public health programmes aimed at improving treatment, reducing rates and consequences of depressive disorders.
