Is rheumatoid arthritis disappearing?

Uhlig T, Kvien TK.

Diakonhjemmet Hospital, Norway.

During the past decades a number of studies have examined the incidence

of rheumatoid arthritis (RA) in different geographical settings and at

different time points. Some studies from the 1970s and 1980s reported a

higher incidence of RA than observed during the recent years where

reported incidence numbers seems to have flatened out at a lower level.

Changing methodology in classification and other methodological issues

may be an equally important explanation besides a real time-dependent

decline of RA incidence. Today we may assume that annually 25-50

individuals out of a population of 100,000 will develop typical RA.
