Socio-demographic Factors of Geriatric Depression

BACKGROUND: Depression is a common mental health problem in geriatric population and the overall prevalence rate of depression in this age group varies between 10 and 20%. OBJECTIVE: To study the socio-demographic factors associated with depression in geriatric population. MATERIALS AND METHODS: A systematic review was done on 74 community-based mental health surveys on depression in geriatric population, which were conducted in the continents of Asia, Europe, Australia, North America, and South America. All the studies were conducted between 1955 and 2005. The researchers had included only community-based cross-sectional surveys and some prospective studies that had not excluded depression on baseline. These studies were conducted on homogenous community of geriatric population in the world, who were selected by simple random sampling technique. A qualitative analysis was conducted to study the socio-demographic factors of depression. RESULTS AND CONCLUSION: The two non-modifiable risk factors found to be significantly associated with depression in geriatric population were “older age group” and “female gender”. However, the potentially modifiable risk factors for depression in the geriatric population were identified as low socioeconomic status, loss of spouse, living alone, chronic co-morbidities, cognitive impairment, bereavement and restricted activities of daily living (ADL).
