Relationship between the Level of Physical Activities and Quality of Life of Predialysis Patients with Chronic Kidney Disease (CKD).

[Purpose] The purpose of this study was to examine whether an inclination towards exercise and the level of physical activity influences quality of life (QOL) of predialysis patients with chronic kidney disease (CKD). [Subjects] The subjects were 74 predialysis CKD patients. [Method] We investigated age, gender, employment, physical activities (International Physical Activity Questionnaire), QOL (SF-36 health survey), inclination towards exercise in these individuals, and looked for relationships among the items. The patients were divided into 2 groups, namely, the high physical activity group and the low physical activity group, on the basis of the amount they exercised and the exercise standard 2006. We compared age, gender, employment, physical activity, renal function, and QOL measures between the 2 groups. [Result] There were no significant correlations between physical activities, inclination towards exercise and QOL. Notably, however, the age and mental components of QOL were significantly higher among patients in the high physical activity group than among patients in the low physical activity group. [Conclusion] These results suggest that a high level of physical activity may affect the mental component of QOL in predialysis CKD patients. [ABSTRACT FROM AUTHOR]
