Overview
Epidemiology and Demographics
Incidence
- The incidence of rheumatoid arthritis is approximately 40 per 100,000 individuals worldwide.[1]
Prevalence
- The prevalence of rheumatoid arthritis is approximately 1 percent in Caucasians per 100,000 individuals worldwide.
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
- Patients of all age groups may develop rheumatoid arthritis .
- The peak onset of disease is between the age of 50 and 75 years.
Race
- Rheumatoid arthritis usually affects individuals of the Native American groups.
- Black persons from the Caribbean region individuals are less likely to develop rheumatoid arthritis .
Gender
- Women are three times more commonly affected by rheumatoid arthritis than men.[2]
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
Developing Countries
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.[3]
- 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.[4]
