US adults with visual impairments meeting 24-h movement guidelines: Updated national prevalence estimates.

BACKGROUND: Despite known benefits of engaging in recommended amounts of physical activity (PA), sleep, and sedentary behavior (SB), little is known about how adults with visual impairments (VIs) meet these guidelines in isolation or simultaneously. OBJECTIVE: This study estimated (a) the prevalence of US adults with VIs who are partially or fully meeting the 24-h movement guidelines, and (b) the differential contribution of work-related, leisure, and transportation to total time accrued for PA. METHODS: A cross-sectional sample of adults with VIs (n = 466) was drawn from the National Health and Nutritional Examination Survey (NHANES) 2015-2018 combined datasets. Guideline adherence was measured using self-report items for average time spent physically active, sitting and sleeping. Weighted prevalence estimates were produced for meeting guidelines separately and in combination. The average percent of PA minutes accrued across work-related, leisure and transportation were compared among those meeting PA guidelines. RESULTS: An estimated 29.6% (SE = 3.6) of US adults with VIs met all three guidelines. An estimated 59.3% (SE = 3.5) adults with VIs met PA guidelines alone or in combination with SB and sleep. Within this group, the majority of weekly PA minutes (average 63.9%) was accrued at work. CONCLUSIONS: An estimated two thirds of adults with VIs are not engaged in healthful 24-h movement behaviors. Targeted interventions for adults with VIs are warranted that may require a comprehensive approach to PA, SB, and sleep. Work emerged as an important location for adults with VIs to accrue PA, inviting future research to explore associations between employment and 24-h movements within this population.

24-Hour Movement Behaviors Among US Adults With Functional Disabilities.

This study aimed to quantify and compare physical activity, sitting time, and sleep behaviors among US adults with and without disabilities using the 2020 Canadian 24-hour movement framework. The weighted prevalence of 24-hour movement guideline adherence was estimated among a nationally representative sample from the 2017 to 2018 National Health and Nutrition Examination Survey of US adults (18-65 years old) with (n = 1070) and without (n = 33,370) functional disabilities in vision, hearing, mobility, cognitive, and self-care domains. The adjusted odds of single and combination guideline compliance were estimated by disability type, in reference to adults without disabilities, using separate multivariable logistic regressions. After adjusting for age, sex, and income, adults with disabilities in mobility, cognitive, or self-care domains had approximately half the odds of meeting all 3 guidelines, compared with adults without disabilities (adjusted odds range: 0.49-0.77). Significantly lower adherence was observed among adults with functional disabilities, compared with no disabilities, for sleep, and moderate to vigorous physical activity, but not sedentary guidelines. This report establishes baseline prevalence estimates for guidelines compliance among US adults with functional disabilities ages 18-65 years old. Low guideline adherence, and evidence for significant differences in physical activity and sleep, signals a need to further explore combination health behaviors among adults with disabilities.
