Scientists estimate that about 2.1 million people, or 1 percent of the U.S. adult population, have rheumatoid arthritis. Interestingly, some recent studies have suggested that the overall number of new cases of rheumatoid arthritis may actually be going down. Scientists are now investigating why this may be happening.
Rheumatoid arthritis occurs in all races and ethnic groups. Although the disease often begins in middle age and occurs with increased frequency in older people, children and young adults also develop it. Like some other forms of arthritis, rheumatoid arthritis occurs much more frequently in women than in men. About two to three times as many women as men have the disease.
By all measures, the financial and social impact of all types of arthritis, including rheumatoid arthritis, is substantial for individuals who suffer from arthritis. From an economic standpoint, the medical and surgical treatment for rheumatoid arthritis and the wages lost because of disability caused by the disease add up to millions of dollars. Daily joint pain is an inevitable consequence of the disease, and most patients also experience some degree of depression, anxiety, and feelings of helplessness. In some cases, rheumatoid arthritis can interfere with a person’s ability to carry out normal daily activities, limit job opportunities, or disrupt the joys and responsibilities of family life. However, there are arthritis self-management programs that help people cope with the pain and other effects of the disease and help them lead independent and productive lives. These programs are described later in the section Diagnosing and Treating Rheumatoid Arthritis.
