While arthritis has been plaguing man since the dawn of time, there are many things about the disease of which most people are unaware.  From how it got its name to the economic toll it takes on our country, here’s a look at the top ten most interesting, little known facts about arthritis.

1. Arthritis is far from a new disease.  In fact, many researchers believe it has been a part of civilization since the beginning of time, even affecting dinosaurs millions of years ago.  Researchers also believe that skeletal remains from humans living around 4500 B.C. show signs of the disease.


2. Did you know that the word arthritis literally means joint inflammation?  That’s right, the word arthritis comes from the Greek words for joint (arthro) and inflammation (-itis).


3. There are over 100 forms of arthritis, including little talked about diseases like Kawasaki disease, which involves inflammation of the blood vessels, and Sweet's syndrome, which is a skin condition marked by fever and painful skin lesions. 


4. Were you aware that arthritis is the most common cause of disability in the United States?  According to the CDC, arthritis and rheumatic conditions cost the U.S. economy $128 billion annually and result in 44 million outpatient visits and 9,367 deaths each year.


5. Movement is one of the best treatment options for arthritis and can help most people prevent the onset of the disease in the first place. The U.S. Department of Health & Human Services (HHS) reports that strong evidence indicates both endurance and resistance types of exercise provide considerable disease-specific benefits for persons with osteoarthritis (OA) and other rheumatic conditions.


6. Osteoarthritis is the most common form of arthritis and is a chronic disease that affects some 27 million Americans. OA is characterized by the breakdown of cartilage, which can cause stiffness and pain.


7. There are two types of OA – primary and secondary. Primary osteoarthritis is generally associated with aging and the "wear and tear" of life. The older you are, the more likely you are to have some degree of primary osteoarthritis. Secondary osteoarthritis, in contrast, tends to develop relatively early in life, typically 10 or more years after a specific cause, such as an injury or obesity.
8. Did you know that children get arthritis too?  Nearly 300,000 children in the United States are living with juvenile arthritis.  Juvenile arthritis (JA) refers to any form of arthritis or an arthritis-related condition that develops in children or teenagers who are less than 18 years of age.


9. Juvenile arthritis is one of the most common chronic childhood conditions, occurring nearly as often as insulin-dependent juvenile diabetes.  The most common form of arthritis in children is juvenile rheumatoid arthritis (JRA), which has two peaks of onset: between 1 and 3 years of age and between 8 and 12 years of age.


10. Arthritis is more common among women (24.9%) than men (18.1%), and girls are twice as likely to develop juvenile rheumatoid arthritis as boys.
