Adults with mobility disability may have more difficulty engaging in aerobic physical activity (PA). Understanding PA behaviors among adults with and without mobility disability can help inform development of inclusive PA interventions.
PURPOSE: To determine the prevalence of (1) meeting the aerobic PA guideline; (2) reporting ≥1 leisure-time aerobic activity; and (3) the most frequently reported activities, among U.S. adults aged 20-64 years with and without mobility disability.
METHODS: We used self-reported data from 13,690 adults aged 20 to 64 years who participated in the 1999-2006 National Health and Nutrition Examination Survey. Respondents who reported any difficulty walking for ¼ mile or walking up 10 steps without resting were classified as having a mobility disability. Respondents reported the type, frequency, and duration of leisure-time aerobic activities in which they engaged in the past 30 days. We classified adults who reported ≥150 moderate-intensity equivalent minutes/week of aerobic PA as meeting the aerobic guideline. For adults with and without mobility disability, we calculated prevalence estimates for meeting the aerobic guideline, reporting ≥1 leisure-time aerobic activity, and among those, the types of activities most frequently reported.
RESULTS: About 7% of adults aged 20-64 years reported mobility disability. A lower percentage of adults with mobility disability than those without met the aerobic guideline [21.6% (95% CI: 18.6, 25.1) vs. 42.4% (95% CI: 40.8, 44.1)] and engaged in ≥1 activity [43.0% (95% CI: 39.2, 46.9) vs. 68.2% (95% CI: 66.5, 69.9)]. Among those reporting any leisure-time aerobic activity, top activities were walking (61.0%), dance (17.9%) and bicycling (14.0%) among adults with mobility disability, and walking (53.6%), bicycling (19.5%) and dance (13.5%) among adults without disability.
CONCLUSION: Nearly 8 in 10 adults with mobility disability aged 20-64 years do not meet the aerobic guideline, putting them at greater risk of poor health outcomes than adults without this disability. Among adults who engage in leisure-time aerobic activity, walking is the most common activity regardless of mobility disability. These results suggest the need to evaluate whether promoting walking among those with mobility disability can increase their PA participation.
