Abstract
The purpose of this study was to clarify the relationship between quality of life (QOL) and mortality using a three year longitudinal study among the elderly. The subjects were residents (between 65 and 84 years old) in Shizuoka Prefecture. The baseline data such as age, sex, medical histories, life style, mobility, and QOL (using the "Index of QOL") were collected in 1999 (n=14001). 781 people from baseline survey died during three-year (1999-2001) , and 11509 people lived, and 1711 people were missing. The results were as follows : (1)Low score on "Index of QOL" was significantly related to three-year mortality. (2) Logistic regression analysis adjusted for sex, mobility, and medical histories indicating odds of mortality showed significantly high with lower score in the Index of QOL. These findings suggest that mortality affected the QOL among the elderly.
