Prevalence of depression in older adults living in ecuador and contributing factors: A population-based study

Objective To estimate the prevalence of depression in the older population of Ecuador and explore the independent associations of key socio-demographic and health-related factors with moderate/severe depression. Methods A cross-sectional study was conducted using a national database. The outcome variable was estimated using the Short Form of the Geriatric Depression Scale. A cut-value of >9 was used to ascertain the outcome variable. We conducted bivariate and logistic regression analysis. Results The study sample consisted of 5 235 subjects, with a median age of 70 years, 53.5% were female, and 44.9% of the sample was living in rural areas. Our study found a prevalence of any depression of 35.4%. Individuals were classified as having mild depression (1 239, 23.7%), moderate depression (457, 8.7%), and severe depression (156,~3%). The prevalence of moderate/severe depression was of 11.7%. Among socio-demogra-phic factors, no education (OR=3.69 [95% CI: 1.35-11.94]), Afro-Ecuadorian race (OR= 2.1 [1.03-4.06]), living alone (OR=2.37 [1.67-3.31]), perception of insufficient income (OR= 3.56 [2.14-6.38]), and suffering physical abuse (OR=2.33 [1.59-3.36]) remained statistically significant. Among health-related factors, drinking alcohol (OR=0.27 [0.08-0.66]), exercise (OR=1.68 [1.24-2.31]), incontinence (OR=2.00 [1.54-2.59]), lower perception of hearing (OR=2.19 [1.41-3.32]), cancer (OR=1.90 [1.00-3.51]), and being functionally dependent (OR=1.59 [1.22-2.08]) remained statistically significant. Conclusions Our investigation brings light to an important public health problem in Ecua-dor. Addressing depression and its contributing factors may help to improve the quality of life and long-term health outcomes in Ecuador’s growing older population.
