Trends in Prevalence of Functional Disability in Rheumatoid Arthritis Compared With the General Population

The objective of the study was to assess trends in functional disability (FD) in patients with rheumatoid arthritis (RA) vs individuals without RA. This retrospective population-based study included 586 patients with RA and 531 individuals without RA. Information on activities of daily living was obtained from self-report questionnaires. The prevalence of FD was higher in those with RA (586 [26%]) vs those without RA (531 [11%]) at RA incidence/index date (P.001), with persistent excess over the follow-up and calendar time. Patients with RA had a 15% or higher prevalence of FD than individuals without RA in most age groups. Patients with RA have a higher prevalence of FD across RA duration, age, and calendar time than those without RA.
