Arthritis Prevalence Projected to Reach 25% by 2030
An estimated 46.4 million US adults, or approximately 21% of the adult population, self-reported a physician-diagnosed form of arthritis, which is the leading cause of disability in the United States, according to 2005 data collected by the National Arthritis Data Work group. The work group estimates that by 2030, the number of US adults aged 18 years and older with arthritis or other rheumatic conditions will jump to nearly 67 million (25% of the adult population)-an increase of about 40% (Figure 1).

About 27 million US adults have osteoarthritis, one of the most common forms of arthritis, an increase from the 1995 estimate of 21 million adults (Figure 2). Rheumatoid arthritis affects 1.3 million US adults, a decline from the estimated 2.1 million adults in 1995 resulting from a combination of more restrictive classification criteria and a drop in prevalence. Approximately 3 million US adults had self-reported gout in 2005, an increase from the 1995 estimate of 2.1 million adults with the condition.

The workgroup also estimated the 2005 incidence of other rheumatic conditions. An estimated 5 million US adults have fibromyalgia, and between 4 million and 10 million US adults have carpal tunnel syndrome.
Although the workgroup did not study costs, direct and indirect costs attributed to arthritis were $127.6 billion in 2003, up from $86.2 billion in 1997 (Figure 3).

An estimated 8.8% of US adults, or nearly 19 million, self-reported arthritis-attributable activity limitations in 2005. This outcome is projected to increase to 9.3% of US adults (25 million) by 2030.
