A study of mental health in community-dwelling older persons--influence of cared elderly

Abstract

This study aimed to evaluate mental health of elderly persons living in the community and understand the various backgrounds and effects of care giving. The study used a questionnaire from similar to the one used by Matsubayashi et al in the Kahoku-cho study. The Japanese Version of General Health Questionnaire 12 (GHQ-12) was used to evaluate mental health. Responses were received from 2,799 (81.5%) of 3,432 Numura-cho residents (81.5%). After removing inadequate responses, 1,268 (36.9%) (575 men and 693 women) were analyzed. Fifty-five men (9.6%) and 69 women (10.0%) were caring for someone at home. Multiple logistic regression analysis which examined the relation between mental health and the background factors such as having someone to care for, revealed that their mental health was significantly poor compared to those having no one to care for (odds ratio (OR) = 2.01, 95% confidence interval (CI), 1.29-3.15). As for the relation between the degree of care giving and their mental health, the subjective burden was significantly poor at 72-100% (OR = 3.40, 95% CI, 1.71-6.78) and for those with three to eight years of care-giving (OR = 2.22, 95% CI, 1.00-4.90), disabled activity of daily living (almost bed ridden) of the cared for person (OR = 5.53, 95% CI, 2.23-13.7), severely demented state (OR = 5.13, 95% CI, 2.14-12.3), their mental health was significantly poor. However, being able to participate in an event (OR = 0.12, 95% CI, 0.03-0.49) and strong emotional support (OR = 0.12, 95% CI, 0.03-0.49) were negatively associated with caregivers' psychiatric distress. Having someone to care for largely affected mental health of the elderly to subjects living in the community. Services should be devised to serve the needs such as psychological care of care-givers as well as those being cared for.
