JIA is the most common cause of chronic arthritis in childhood and a leading cause of short- and long-term disability .
- between 0.07-4.01 per 1000 children are thought to be affected worldwide (1,2)
Incidence of the disease is estimated to be between 1-22 in 100,000 and a disease prevalence of 7-150 in 100,000
- a study from Turkey reported a prevalence of chronic arthritis in childhood of 64 in 100,000 while a study from Australia showed a prevalence as high as 400 in 100,000 (1)
Frequency of JIA subtypes varies according to geographical areas or ethnic groups:
- oligoarthritis is the most common subtype in Western countries
