Occupational work and quality of life in osteoarthritis patients.

The ageing European population suffers from chronic diseases, including osteoarthritis (OA). The aim of this study was to investigate the work activity/ability, the quality of life and reciprocal interaction between both in OA patients. A total of 750 OA outpatients were evaluated by a questionnaire study. Work Ability Index (WAI) and General Health Questionnaire 28 (GHQ 28) were used as tools for work ability and quality of life assessment, respectively. Statistical analysis was performed by means of ANOVA tests. A total of 22.2% OA patients were still active professionally. They had decreased work ability and decreased quality of life. A worse work ability and a worse quality of life were related with a blue-collar work, multi-joint localization of OA and co-existence of other diseases. A negative correlation was found between general scores of GHQ 28 and that of WAI and five WAI components. Findings indicate a need for work ability promotion among OA working patients to maintain both, better quality of life and higher level of satisfaction with job.
