The number of Americans with arthritis or chronic joint symptoms has risen steadily over the past twenty years. Here is a statistical snapshot of these figures:

	1985 - 35 million
	1990 - 37.9 million
	1998 - nearly 43 million (1 in 6 people)
	2006 - 46 million (nearly 1 in 5 adults)
	Arthritis is one of the most prevalent chronic health problems and the nation’s leading cause of disability among Americans over age 15.
	Arthritis is second only to heart disease as a cause of work disability.
	Arthritis limits everyday activities such as walking, dressing and bathing for more than 7 million Americans.
	Arthritis results in 39 million physician visits and more than a half million hospitalizations.
	Costs to the U.S. economy totals $128 billion annually.
	Arthritis affects people in all age groups including nearly 300,000 children.
	Baby boomers are now at prime risk. More than half those affected are under age 65.
	Half of those Americans with arthritis don’t think anything can be done to help them.
	Arthritis refers to more than 100 different diseases that affect areas in or around joints.
	Arthritis strikes women more often than men.

Overall, arthritis impacts both women and men, as follows:

	Women - 24.3 million of the people with doctor-diagnosed arthritis
	Men - 17.1 million of the people with doctor-diagnosed arthritis

The disease can affect various parts of the body. Arthritis causes pain, loss of movement and sometimes swelling. There are over 100 different forms of arthritis, which include:

	Psoriatic arthritis, causes pain and swelling in some joints and scaly skin patches on some areas of the body; it is related to psoriasis of the skin. Approximately 10 percent to 30 percent of people with psoriasis develop psoriatic arthritis. Symptoms include progressive pain, stiffness and joint swelling. Related symptoms are silver or grey scaly spots on the scalp, elbows, knees and/or lower end of the spine, as well as pitting of nails, and swelling in fingers/toes.
	Osteoarthritis, a degenerative joint disease in which the cartilage that covers the ends of bones in the joint deteriorates, causing pain and loss of movement as bone begins to rub against bone. It is the most prevalent form of arthritis.
	Rheumatoid arthritis, an autoimmune disease in which the joint lining becomes inflamed as part of the body’s immune system activity. Rheumatoid arthritis is one of the most serious and disabling types, affecting mostly women.
	Gout, which affects mostly men. It is usually the result of a defect in body chemistry. This painful condition most often attacks small joints, especially the big toe. Fortunately, gout almost always can be completely controlled with medication and changes in diet.
	Ankylosing spondylitis, a type of arthritis that affects the spine. As a result of inflammation, the bones of the spine grow together.
	Juvenile arthritis, a general term for all types of arthritis that occur in children. Children may develop juvenile rheumatoid arthritis or childhood forms of lupus, ankylosing spondylitis or other types of arthritis.
	Systemic lupus erythematosus (lupus), a serious disorder that can inflame and damage joints and other connective tissues throughout the body.
	Scleroderma, a disease of the body’s connective tissue that causes a thickening and hardening of the skin.
	Fibromyalgia, in which widespread pain affects the muscles and attachments to the bone. It affects mostly women.
