To identify the factors relevant to work and activity impairment in patients with rheumatoid arthritis.
In total, 1274 consecutive patients were included. Work and activity impairment were measured by the Work Productivity and Activity Impairment questionnaire, and related clinical factors were examined.
Work and activity impairment was reported by 67.4% of the patients. Multivariable linear regression analyses revealed pain and non-remission to be associated with activity impairment and presenteeism. Patients in remission had significantly less activity impairment and presenteeism than those with low disease activity.
Remission achievement is essential for ensuring work performance and activity.
