* Doctor-diagnosed arthritis was defined as a yes response to the question “Has a doctor, nurse, or other health professional ever told you that you have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia?”
† Age standardized to the 2000 U.S. projected population, using three age groups: 18–44, 45–64, and ≥65 years.
§ Median and range were calculated from estimates for the 50 states and the District of Columbia.
