介護保険サービスを利用している高齢者のQuality of LifeおよびActivity of Daily Livingに及ぼす運動介入の影響 <学位論文要旨>

The purpose of this study was to confirm the importance of enhancing quality of life (QOL) and activity of daily living (ADL) in elderly people, and to examine methods of exercise intervention for QOL and ADL outcomes in elderly people who use nursing care insurance services.

Chapter 2 clarifies the relationship between QOL, ADL, and changes in the level of independence in elderly residents. Higher QOL outcomes (sense of well-being, satisfaction with social support, independence, and behavioral competence) were significantly associated with a reduction in the risk of a lower level of independence.

Chapter 3 examines the effects of exercise intervention using 4 types of machines on ADL and subjective well-being scales in elderly local residents. Subjective well-being scales significantly increased between baseline and 3 months later.

Chapter 4 clarifies relations between physical activity levels and ADL and QOL scales in elderly nursing home residents. Physical activity levels were assessed by an accelerometer. QOL scales were significantly correlated with gait ability and daily duration of low-intensity physical activity (under 3 METs).

Chapter 5 shows that an outdoor walking program made the subjects feel better immediately afterwards, as well as QOL scales in geriatric nursing home residents.

Chapter 6 examines differences in changes in QOL, ADL and physical function levels among geriatric nursing home residents undergoing 2 exercise intervention programs. The participants were randomly divided into 2 groups: the outdoor walking program group and the individual physical therapy group. The QOL scales significantly increased after the outdoor walking program.

It is important to enhance QOL, including the promotion of social capital, ADL, and physical function for active aging. This study demonstrated an effect of exercise intervention through evaluation by physical, psychological, and social domains.
