Elders with dementia living in the community with and without caregivers: an epidemiological study.
BACKGROUND
Previous studies of dementia and family caregiving have focused on individuals seeking diagnosis and treatment, and have rarely been conducted in representative community samples. Identifying demented individuals participating in a community survey, we determined (a) the factors associated with demented elderly living alone; (b) the factors associated with the demented elderly having caregivers; (c) the factors associated with increased levels of burden among caregivers of persons with dementia.


METHODS
During an epidemiological survey of a mostly rural U.S. community, the authors identified 116 noninstitutionalized elderly individuals with dementia. These individuals were classified into those living alone and those living with others; both groups were further classified into those with and without identifiable family caregivers. Characteristics of both caregivers and care recipients were examined.


RESULTS
Approximately a third of the subjects with dementia lived alone, and only half of them had caregivers. The average age of the caregivers was 67.4 years, and 73% of them were women. Almost half of the caregivers were spouses, whereas almost a third were offspring, of the demented individuals. Over two thirds of caregivers lived with the subjects. Female caregivers were significantly younger than male caregivers. Multivariate analyses revealed that subjects with dementia who were living alone were independently and significantly more likely to be women and to have dementias of shorter duration, lesser severity, and lesser functional impairment than those living with others. Demented subjects with caregivers were more likely to have greater dementia severity, functional impairment, and cognitive impairment and more current cognitive and behavioral symptoms than those without caregivers. Demented subjects whose caregivers reported higher levels of burden were more likely to be women and to have greater dementia severity, functional impairment, and cognitive impairment and more current symptoms than those whose caregivers had no/minimal burden.


CONCLUSIONS
These results draw attention to the problems of persons with dementia living alone, particularly those without caregivers. Our data also provide epidemiological confirmation of previous clinical/volunteer studies of dementia caregiving, as well as a preliminary assessment of need in the community at large. Living arrangements and caregiver issues should be taken into account when planning services for the elderly.
