# metadata.dc.description.abstract[].value
Background: The epidemiology of depressive disorders presents notable differences among European countries. The objectives of the study are to determine the prevalence, incidence, persistence and remission rates of depressive symptoms and to identify risk factors and differences between four European regions. Method: Prospective cohort design using data from waves 5 and 6 (2013-15) of the Survey of Health, Ageing and Retirement in Europe. Sample size included 31,491 non-institutionalized adults aged 65+. Depressive symptoms were assessed using the EURO-D. Results: The prevalence of depressive symptoms (EURO-D ≥4) was 29.8% and 31.5%in waves 5 and 6, respectively. The risk factors associated depressive symptoms were poorer self-rated health, loneliness, impairment in ADL, female gender and financial difficulties. Incidence was 6.62 (99.9% CI: 6.61-6.63)/100 person-years and the persistence and remission rates were 9.22 and 5.78, respectively. Regarding the differences between European regions, the incidence (4.93 to 7.43) and persistence (5.14 to 11.86) rates followed the same ascending order: Northern, Eastern, Continental and Southern. The remission presented higher rates in the Eastern and Southern (6.60-6.61) countries than in the Northern and Continental (4.45-5.31) ones. Limitations: The EURO-D scale is unable to distinguish between clinically relevant depressive symptoms and major depression. Conclusion: The risk factors related to the incidence of depressive symptoms differed across European regions. In countries of eastern and southern Europe the most important predictors were female gender and impairment in ADL. Poorer self-rated health and older age were more relevant in the Northern countries, and chronic diseases were a key factor in the Continental region.
