* Respondents were classified as having arthritis if they responded “Yes” to the question, “Have you ever been told you have some form of arthritis, rheumatoid arthritis, gout, lupus, or fibromyalgia?”

^† Respondents with arthritis were classified as engaging in physical activity if they responded “Yes” to the question, “During the past month, other than your regular job, did you participate in any physical activities or exercises such as running, calisthenics, golf, gardening, or walking for exercise?”

^§ Those who engaged in physical activity were classified as participating in an activity if they reported this activity in response to two questions: 1) “What type of physical activity or exercise did you spend the most time doing during the past month?” or 2) “What other type of physical activity gave you the next most exercise during the past month?” Participants who reported one activity but had missing data for the other most frequent activity (e.g., “don’t know” or “refused”) were included in the analysis. The sum of respondents for all activities exceeds the total number of respondents since each respondent could report up to two activities. Survey interviewers coded activities not listed among the 74 activities in the BRFSS Activity List for Common Leisure Activities into a single, heterogeneous “other” category representing a wide variety of different activities (n = 13,241; 13.7% [95% CI: 13.2–14.1]). https://www.cdc.gov/brfss/annual_data/2019/pdf/codebook19_llcp-v2-508.HTML

^¶ In 2019, New Jersey did not collect enough data to meet the minimum requirement for inclusion in the BRFSS public-use data set.

** The 74 activities were organized into major headings using a modified version of the 2011 Compendium of Physical Activities by Ainsworth, et. al. (https://cdn-links.lww.com/permalink/mss/a/mss_43_8_2011_06_13_ainsworth_202093_sdc1.pdf). Activities were grouped on the basis of similarity and on response rates, with activities having <400 respondents combined into “Other” categories corresponding to the major headings.

^†† Some calisthenics activities might be classified as aerobic conditioning exercise.

^§§ Home activities included household activities (e.g., vacuuming, dusting, or home repair), child care, carpentry, and painting or wallpapering.
