Rheumatoid arthritis: key figures and prevalence

Rheumatoid arthritis is the second most common form of arthritis in the UK and the most common inflammatory joint disorder. 


It is difficult to predict how rheumatoid arthritis will develop, because it affects different people in different ways. A study of a large group of people with the condition gave the following results:

* 75 per cent continued having some joint pain, swelling and flare-ups
* 20 per cent always have very mild rheumatoid arthritis
* 5 per cent develop severe disease with extensive disability

Women are three times more likely to be affected than men and the average age is between 35 and 65 for the most frequent cases.
