Doctor-diagnosed arthritis was self-reported in the BRFSS and was not confirmed by a health-care provider; however, such self-reports
have been shown to be acceptable for surveillance purposes. In 2000 and 2001, the BRFSS questions were worded, "Have you
ever been told by a doctor that you have arthritis?" In 2002, the wording was changed to "Have you ever been told by a doctor
or other health professional that you have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia?"
Because age affects the likelihood of having arthritis, it is beneficial to adjust for the effect of age when comparing populations.
This method helps to determine if a certain population has a factor, which contributes to arthritis more than the effect of
age. Therefore, these data have been age-adjusted to the U.S. 2000 standard population. Rates are based on eight age groups:
18-24, 25-34, 35-44, 55-64, 65-74, 75-84, and 85+.
Beginning in 2011, BRFSS data include both landline and cell phone respondent data along with a new weighting methodology
called iterative proportional fitting, or raking. This methodology utilizes additional demographic information (such as education,
race, and marital status) in the weighting procedure. Both of these methodology changes were implemented to account for an
increased number of U.S. households without landline phones and an under-representation of certain demographic groups that
were not well-represented in the sample. More details about these changes can be found at: http://health.utah.gov/opha/publications/brfss/Raking/Raking%20impact%202011.pdf.

How We Calculated the Rates
Includes survey respondents ages 18 and older who reported being told by a doctor or other health professional that they had
some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia. Excludes those with missing, don't know, and refused
