Dysthymic disorder in the aged in the community

Summary The prevalence of dysthymic disorder and and its relationship to social and health variables were investigated in a Finnish population aged 60 years or over. The prevalence was lower in men (17.2 per 100) than in women (22.9 per 100). In the total population the occurrence was higher in the widowed (24.9 per 100) than in the married (18.3 per 100). In men, dysthymic disorder was more common in those with a lower educational level (22.6 per 100) than with a higher educational level (15.1 per 100), and more common in persons receiving long-term institutional care or home nursing or home help (28.7 per 100) than in persons living independently at home (14.6 per 100). The rate was not related to age, marital status or occupation. In women, the occurrence was not related to age, marital status, education, occupation or form of social and health care. The female rate was higher than the male in the older group (70 yrs. +), in married persons, in those with a higher educational level and in those living independently at home. Underdiagnosing was evident. The occurrence of dysthymic disorder was related to poor health and poor functional status and to the occurrence of social and health stressors. No differences were found in the occurrence of the related factors between persons with dysthymic disorder and persons with major depression. Our results support the conclusion that the majority of cases of dysthymic disorders in the elderly are affective illnesses and not personality disorders.
