Burden among caregivers of frail elderly in Japan.

要旨

The present study was conducted in order to investigate the factors related to the feelings of psychological stress, called heavy burden, in caregivers who took care of frail elderly in the eastern part of Fukuoka Prefecture, Kyushu, Japan. Fifty-eight caregivers answered a self-administered questionnaire, involving the Japanese version of the Zarit Caregiver Burden Interview (ZBI) and thus described their own caregiving situation. Compared to caregivers with a light burden, heavily burdened caregivers were less likely to have time to go out without patients, but were more likely to consult physicians. Heavily burdened caregivers spent a longer time on looking after the elderly as well as on physical caregiving, and also used more social services than lightly burdened caregivers. However, the physical disabilities of the patients did not differ between the two groups. Even after controlling for confounding factors, the time spent on looking after frail elderly was found to be a significant factor related to the caregivers' heavy burden (10-24 hrs vs. 0-9 hrs; odds ratio: 5.35, 95% confidence interval: 1.17-25.58). These findings suggest that looking after frail elderly for a long time seems to be an important factor related to caregivers' developing psychological feelings of heavy burden.
