About 21% of U.S. Adults Have Arthritis
Nearly 67 Million Adults Will Have Been Diagnosed With Arthritis by 2030, Experts Predict
Jan. 2, 2008 -- More than 46 million U.S. adults -- more than 21% -- report
ever being diagnosed with arthritis, and their ranks are expected to swell
to 67 million adults with doctor-diagnosed arthritis by 2030.
That news appears in January's edition of Arthritis &
Rheumatism, along with these figures:
Osteoarthritis: Nearly 27 million adults
Fibromyalgia: 5 million adults
Gout: 3 million adults had gout in the past year and 6 million had
ever had gout
Rheumatoid arthritis: 1.3 million adults
Polymyalgia rheumatica: 711,000 adults
Sjogren's syndrome: Between 400,000 and 3.1 million adults
Juvenile arthritis: 294,000 children
Lupus: Between 161,000 and 322,000 adults
Giant cell arteritis: 228,000 adults
Other forms of arthritis, including ankylosing spondylitis and psoriatic
arthritis, together affect between 600,000 and 2.4 million adults. And between
4 million and 10 million people have carpal tunnel syndrome, the report
Osteoarthritis, the most common form of arthritis, became even more common
in recent years. In 1995, an estimated 21 million U.S. adults had
osteoarthritis; that's almost 6 million fewer than at the researchers' last
Gout also appears to be on the rise. The number of people reporting gout in
the previous year grew from 2.1 million in 1995 to 3 million a decade
Arthritis became more common with age and was more commonly reported by
women than men.
Almost 9% of people reporting arthritis -- or an estimated 19 million people
-- said arthritis limited their activities.
Apart from arthritis, 59 million people reported having low back pain and 30
million said they'd had neck pain in the previous three months.
Data came from government surveys conducted from 2003-2005 and from smaller,
local surveys for certain types of arthritis. Participants' medical records
weren't checked to confirm their self-reported arthritis diagnosis.
The researchers applied the survey findings to the U.S. population based on
data from the 2005 census.
The new arthritis statistics are "the best available prevalence
estimates for the U.S., but for most specific conditions, more studies ... are
needed," write the CDC's Charles Helmick, MD, and colleagues.
