Abstract
The aims of this study were to reveal pain prevalence and the situation of pain which affects health- related QOL among community-dwelling frail elderly in the Long-Term Care Prevention Project for persons at risk of being in need of support. The subjects were 495 elderly people, with an average age of 84.7(±5.4). The pain prevalence of the past month was 73.1% in this study and the most usual location of pain was the lower back, with the average pain locations being 1.9(±1.0). In the SF-8 PCS (Physical component summary) with the pain group 44.3(±5.7) was significantly lower in the no pain group 52.1(±4.0). In the SF-8 MCS (Mental component summary) there was no significant difference between the pain group 51.9(±6.2) and the no pain group 51.0(±5.7). Multiple regression analysis was performed using the SF-8 PCS and the SF-8 MCS in the pain group as dependent variables. The factors of SF-8 which controlled the PCS were: the worst pain intensity; when the pain has interfered with your walking ability; the pain interfered with relations with other people; the neuropathic pain screening score; and the pain interfered with enjoyment of life. The factors of SF-8 which controlled the MCS were pain which interfered with mood and the pain which interfered with relations with other people.
