Abstract
AIMS: To evaluate factors associated with depression in elderly. METHODS: During 2005-2007, 553 men and 637 women (aged 65 to 100 yrs) living in various Greek islands and in Cyprus participated in the study. The sampling was random and multistage (according to age sex distribution of the referent population). Depressive symptoms were evaluated using the Geriatric Depression Scale (GDS). RESULTS: Twenty five per cent of men and 35% of women were classified in the highest GDS category (i.e. GDS score > 10), indicating intense depressive symptoms, while 54% of men and 70% of women scored above the depression cut-off (i.e. GDS score > 5) indicating mild-to-severe depressive symptoms. Among the investigated characteristics, living in urban environment, physical inactivity and history of hypertension were correlated with the presence of depressive symptoms (p < 0.05), after adjusting for various confounders. Moreover, the consumption of fish, vegetables and cereals is more prevalent among people with low or moderate depression (p < 0.05). CONCLUSIONS: The prevalence of depression is quite high between elderly people living in Greek islands and Cyprus. Urban environment that may also interact with sedentarism and unhealthy dietary habits seems to promote depression in the studied population. Efforts to lower the prevalence of depression in the elderly should target on the aforementioned factors that employ functional impairment, social environment and dietary habits.
