Arthritis and other rheumatic conditions affect approximately 46 million adults in the United States. Because U.S. adults are living longer, the number living with arthritis likely will increase. This report projects the number of adults in each state who will have doctor-diagnosed arthritis and arthritis-attributable activity limitations in 2030. Created: 5/4/2007 by MMWR.

A Quick Look at Arthritis
Projected 2030 Prevalence of Self-Reported Doctor-Diagnosed Arthritis and
Arthritis-Attributable Activity Limitations — United States

Prevention. CDC – safer, healthier people.
[Matthew Reynolds] Welcome to A Cup of Health with CDC, a
weekly broadcast of the
MMWR, the Morbidity and Mortality Weekly Report. I’m your host, Matthew

a number of medical conditions that cause arthritis, but most commonly it develops
when joint cartilage breaks down due to wear and tear.
Today we are going to be talking to Dr. Mark Freedman about the impact of
Freedman and his colleagues in CDC’s Center for Chronic Disease Prevention
Health Promotion are doing research that helps determine how many Americans
affected by arthritis in the future.
Welcome to the show, Dr. Freedman.
[Dr. Freedman] Thank you Matthew. It’s great to be here.
[Matthew Reynolds] Dr. Freedman, I’m sure that many of
our listeners suffer from joint
pain and possibly arthritis. Are there different kinds of arthritis?
[Dr. Freedman] Yes, arthritis refers to over 100 different
rheumatic conditions that
primarily affect the joints and the tissues surrounding the joints. There are
types, non-inflammatory and inflammatory arthritis. Non-inflammatory arthritis
common, and it is limited to the joints and surrounding tissues. The most common
of non-inflammatory arthritis is osteoarthritis (or degenerative joint disease),
occurs when the thin line of cartilage at the end of the bones breaks down and
disintegrates. The most commonly affected joints include the knees, hips, hands,
ankles, and spine. The second type of arthritis is inflammatory which is less
This also effects joints and the surrounding tissues, but other organs, such
as the heart,
lungs, kidneys, and eyes can also be involved. Some examples include rheumatoid
arthritis, gout, lupus, ankylosing spondylitis, and psoriatic arthritis.
[Matthew Reynolds] You mentioned two major categories of arthritis.
If you were to put
those together and talk about arthritis as a whole in the United States, how
[Dr. Freedman] Well, Matthew, arthritis is very common and
our study suggests it will
become even more common in the coming decades. Arthritis currently affects 46
U.S. adults and is the leading cause of physical disability in U.S. adults.
responsible for $128 billion annually in healthcare costs and we’re projecting
increases of up to 67 million U.S. adults with arthritis by the year 2030.
[Matthew Reynolds] Those are staggering numbers. You’ve
just finished a study that
found that the number of people with arthritis is increasing in the United States.
[Dr. Freedman] Well, we project the increases in the number
of people with arthritis in
coming decades mostly because the U.S. population is projected to increase,
in the older, higher risk age groups. Also, obesity continues to be a major
problem, and obesity is a known risk factor for knee osteoarthritis. This could
even more arthritis than we are projecting at this point.
[Matthew Reynolds] In your study, you were able to estimate
how many people are
expected to be diagnosed with arthritis in the United States. What did you learn
the number of people affected with arthritis in the future?
[Dr. Freedman] We used Census population projections to estimate
how much arthritis
there would be in the year 2030 in each state, and we found that arthritis is

increases of 50% or more of current levels. In Arizona, Florida and Nevada we
expecting to see double the number of people with arthritis by 2030. Most of
increases are seen in the “sunbelt” and western states. California,
Carolina, and Texas are projected to each have over a million new cases by the
2030. These states are also predicted to have the largest increases in overall
populations and an increased number of adults over 65. These increases are expected
to add a significant burden to states’ healthcare and public health systems.

[Matthew Reynolds] Your study predicts these increases in the
number of people with
arthritis by 2030. How can people prevent arthritis or manage it if they already
[Dr. Freedman] Well Matthew, arthritis is already a large problem,
and our study says
we can expect the problem to keep growing in nearly every state. Although most
arthritis is not curable, there are some basic steps we can take to learn to
manage arthritis. What bothers us is that so many people are not taking these
steps. These include staying physically active, which leads to decreased pain
improved quality of life for people with arthritis; losing excess weight, which
decrease the burden on your joints; and getting educated about arthritis. Some
important self-management steps include knowing the type of arthritis that you
and developing skills to learn how to manage your arthritis when the doctor
[Matthew Reynolds] What is CDC doing to help?
[Dr. Freedman] Well, currently CDC funds 36 state health department
programs that partner with the state chapters of the Arthritis Foundation to
availability of these proven exercise and self-management strategies. You can
more about these programs on our website at cdc.gov/arthritis, or by contacting
local chapter of the Arthritis Foundation.
[Matthew Reynolds] Dr. Freedman thanks for taking the time
to talk with us today.
[Dr. Freedman] It’s been my pleasure.
[Matthew Reynolds] That’s it for this week’s show.
Don’t forget to join us next week.
Until then, be well. This is Matthew Reynolds for A Cup of Health with CDC.
