Respondents classified as inactive reported that they participated in physical activity; however, the duration of the activity did not meet the 2018 physical activity guidelines of a minimum of 10 min in duration or the activity was not considered aerobically active.
All estimates are weighted according to BRFSS sampling methodology. Some percentages do not total to 100.0% due to rounding.
P value is calculated based on a paired t-test. The referent group is those that reported walking.
