As the leading cause of disability in the U.S.,1 arthritis is highly prevalent among adults and associated with substantial activity limitation, work disability, reduced quality of life, and high health-care costs.2-4 An estimated 21.6 percent of the adult U.S. population (46.4 million) reported doctor-diagnosed arthritis in 2005. In addition, 17.4 million (8.3% of the adult U.S. population) have arthritis-attributable activity limitation.5 As the population ages, the prevalence of arthritis (see figure 1) is expected to grow from the current 46.4 million Americans today to 67 million by 2030, an increase of 144%.6

Using Medical Expenditure Panel Survey (MEPS) data, the CDC analyzed national and
state-specific direct costs (i.e., medical expenditures) and indirect costs (i.e., lost earnings) attributable to arthritis and other rheumatic conditions (AORC) in the United States during 2003. The CDC report describes the results of that analysis, which indicated that in 2003 the total cost of AORC in the United States was approximately $128 billion ($80.8 billion in direct and $47.0 billion in indirect costs), equivalent to 1.2% of the 2003 U.S. gross domestic product.8
