[Quality of life, subjective health status and health and life satisfaction in rheumatoid arthritis].

A Japanese version of Arthritis Impact Measurement Scales (AIMS) was developed after the original AIMS Version 2 and utilized for Quality of Life (QOL) measurement in 691 patients with Rheumatoid Arthritis (RA). Various medical (physical and laboratory) examinations, which are widely used in the clinical settings for the assessment of RA activity and severity, were also performed by physicians. Interrelationships between QOL, patient subjective health status, and health and life satisfaction were analyzed with the following results: 1: The effect of QOL impairment by RA upon patients' subjective health rating and health satisfaction were not constant over the range of severity of disease status. Pain was found to lower overall subjective health and health satisfaction regardless of RA class. On the other hand, while the deterioration of mobility aspects of QOL had negative effects upon patients' subjective health status and satisfaction among less-disabled RA patients, any of physical aspects of QOL, including the degree of mobility impairment, showed no significant association with patients' subjective health status and satisfaction in the more disabled. 2: Psychological aspects of QOL (mood and tension) had significant associations with patients' subjective health status and satisfaction. In the less severe group, mood impairment had a significant effect on subjective health and satisfaction, while in the more severe group tension showed a significant association. It was indicated that management of psychological aspects of QOL is important in RA patients to improve and advance their subjective health status and satisfaction. 3: Although social aspects of QOL, i.e. social support, social life and job status, showed no significant relationship to subjective health rating and health satisfaction, those with less disease severity who lacked social support and who had a jobless state were likely to have lower disease acceptance and life satisfaction, while those with more severe disease who had less social interaction manifested lower life satisfaction. These results suggested that social aspects of QOL, while not directly associated with subjective health rating, could be important factors affecting disease acceptance and life satisfaction.
