title: [Risk factors of rheumatoid arthritis].
abstract: Rheumatoid arthritis is a chronic inflammatory joint disease with an annual incidence rate between 25 and 50 per 100,000 individuals. Most likely, a combination of inherited and environmental factors, such as infections, reproductive or hormonal factors, and factors related to life style, is responsible for the disease. Future etiological studies should aim at providing a better insight into the interaction between different risk factors.
