Depression and associated variables in people over 50 years in Spain

Introduction: Depression is a common and disabling psychiatric disorder in adulthood and is associated with higher mortality and functional disability. Objectives: To determine the association between clinical and sociodemographic variables with depression in a sample of people over 50 years old living in Spain, and compare the prevalence of depression with the other Survey of Health, Ageing and Retirement (SHARE) countries. Material and methods:There were 5,830 participants in the Spanish sample of the Wave 5, 2013, of SHARE. Tools used: EURO-D (Depression) and CASP-12 (Quality of Life). Statistical analysis: Bivariate, and binary logistic. Results: The variables associated with depression in the binary logistic regression (EURO-D >= 4) were poor self-perceived physical health (OR = 13.34; 95% CI: 9.74-18.27), having more than 2 difficulties in Activities of Daily Living (ADL) (OR = 4.46; 95% CI: 3.13-6.34) and female gender (OR = 2.16; 95% CI: 1.83-2.56). Depression was more common among participants with Alzheimer (76.4%), emotional disorders (73.9%), Parkinson (57.4%), hip fracture (55.4%), and rheumatism (50.9%). Compared with other European countries, Spain had a percentage of people with depression (29.3%) that was higher than the European average (27.9%). Conclusions: The most important variables associated with depression were poor perceived physical health, presence of difficulties in ADL, and female gender. (C) 2016 SEP y SEPB.
