Overview
Incidence
The overall age- and sex-adjusted annual Rheumatoid arthritis incidence is 40.9/100,000 population.[1].
Age
Onset is uncommon under the age of 15 and from then on the incidence rises with age until the age of 80.
Gender
- An estimate of 1.3 million adults had Rheumatoid arthritis in 2007, affecting women two to three times as often as men. The incidence as well as prevalence of RA in women appears to have increased over the last decade.[2]
- The lifetime risk of RA in adults is 3.6 % for women and 1.7% for men.[3]
Race
- Some Native American groups have higher prevalence rates (5-6%) and black persons from the Caribbean region have lower prevalence rates. First-degree relatives prevalence rate is 2-3% and disease genetic concordance in monozygotic twins is approximately 12-15% compared to 3.5% in Dizygotic twins.[4]
- It is strongly associated with the inherited tissue type Major histocompatibility complex (MHC) class II antigen HLA-DR4 (most specifically DR0401 and 0404) — hence family history is an important risk factor.[5]
