Abbreviation: CI = confidence interval.

* Age standardized to the 2000 U.S. projected population, using three age groups: 18–44, 45–64, and ≥65 years.

Respondents with arthritis who answered 14–30 days to the question “Now thinking about your mental health, which includes stress, depression, and problems with emotions, for how many days during the past 30 days was your mental health not good?”

§ 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?”

Median and range were calculated from estimates for the 50 states and the District of Columbia.
