Depression in the oldest old in urban and rural municipalities

The aim was to compare an urban and a rural old population regarding depression.

A population-based, cross-sectional study in five depopulated areas and one expanding urban city in northern Sweden. Participants aged 85 and above were evaluated for depression. Data were collected from structured interviews and assessments and from relatives, caregivers and medical charts. Depression was screened for using the Geriatric Depression Scale-15 (GDS-15) and evaluated by the Montgomery-Asberg Depression Rating Scale (MADRS).

In total, 29% of the 363 participants were depressed (34% in the rural municipality and 27% in the urban municipality). Fifty-one percent versus 69% were receiving treatment with antidepressants. In the rural areas, those with depression were less frequently treated with selective serotonin reuptake inhibitor (SSRI) medications (36% versus 65%; p = 0.004), instead there were participants treated with Tri Cyclic Antidepressant's (TCA's) (10%, versus 0%; p = 0.0018). A larger proportion of the participants in the urban sample had responded to treatment (59% versus 27%; p = 0.175).

Depression in old age appears to be a common cause of emotional suffering among the oldest old. In the rural areas, depression was more often inadequately treated and it was also treated with inappropriate medications.
