The BRFSS survey is a state-based, random-digit–dialed telephone survey of the noninstitutionalized, U.S. civilian population aged ≥18 years conducted annually in all 50 states, the District of Columbia (DC), Guam, Puerto Rico, and the U.S. Virgin Islands. The 2003 BRFSS survey was the only state-specific survey to assess AAWL among persons with doctor-diagnosed arthritis. Doctor-diagnosed arthritis was defined as a “yes” response to the question, “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?” AAWL was defined as a “yes” response to the following: “In this next question, we are referring to work for pay. Do arthritis or joint symptoms now affect whether you work, the type of work you do, or the amount of work you do?” Participants were asked to choose one of the following to determine their employment status: employed for wages, self-employed, out of work for more than 1 year, out of work for less than 1 year, homemaker, student, retired, or unable to work. Respondents were considered employed if they reported being employed for wages or self-employed. Respondents with missing values for doctor-diagnosed arthritis were excluded from the analysis.
