Nearly 300,000 children in the United States have a form of juvenile arthritis or a rheumatic disease that occurs before age 16. The most common form in children is juvenile rheumatoid arthritis.
The cause of most forms of juvenile arthritis remains unknown. Juvenile arthritis is not contagious, and there is no evidence that foods, toxins, allergies, or vitamin deficiencies play a role. Current research indicates that there may be a genetic predisposition to juvenile arthritis. In other words, the combination of genes a child inherits may contribute to the development of arthritis when combined with other undefined factors.
Most of the symptoms of juvenile arthritis are due to inflammation as a result of imbalances in the immune system. Despite not knowing the exact cause or causes, there are many effective treatments available to help children and their parents manage juvenile arthritis. Experts say that most children with arthritis can expect to live normal lives.
