    Associations Between the Built Environment in GPS-Derived Activity Spaces and Sedentary Behavior, Light Physical Activity, and Moderate-to-Vigorous Physical Activity
    (MDPI, 2025-04-04) Vittor, Dante G.; Wilson, Jeffrey S.; Crouter, Scott E.; Ethier, Benjamin G.; Shi, Ling; Camhi, Sarah M.; Troped, Philip J.; Earth and Environmental Sciences, School of Science
    Built environment and physical activity (PA) studies have predominantly used fixed or home-centric approaches to identify environmental exposures. In this study, GPS-derived daily activity spaces were used to examine the relationships between the built environment and sedentary behavior (SB), light PA (LPA), and moderate-to-vigorous PA (MVPA). Thirty-one adults were assessed with activity monitors and GPS units. Three types of activity spaces were created: 50 m buffered GPS tracks, minimum convex hulls (MCHs), and standard deviational ellipses (SDEs). The environmental variables included land use mix, greenness, and intersection, multi-use trail, bike infrastructure, and bike station densities. Repeated measures regression was used to test the associations for 141 person-days, controlling for age, gender, income, body mass index, crime, precipitation, and temperature. Greenness within MCH activity spaces was positively associated with LPA (p = 0.02). The bike infrastructure density within SDE spaces had a significant positive association with MVPA (p = 0.04). Multi-use trail, bike infrastructure, and bike station densities had significant negative associations with LPA (p ≤ 0.05). There were no significant adjusted associations with SB. The few significant associations in this study varied by outcome and type of activity space. Further studies are needed to determine optimal, yet flexible methods for activity spaces in built environment and PA research.

    COVID-19: Implications for Physical Activity, Health Disparities, and Health Equity
    (Sage, 2021-07-27) Hasson, Rebecca; Sallis, James F.; Coleman, Nailah; Kaushal, Navin; Nocera, Vincenzo G.; Keith, NiCole; Exercise & Kinesiology, School of Health and Human Sciences
    Physical activity is one of the most efficacious pathways to promoting mental and physical health, preventing disease, and, most important during the COVID-19 pandemic, bolstering a stronger immune system. Efforts to “flatten the curve” have resulted in the temporary closure of exercise facilities and gyms, suspension of sport activities, and advisories to avoid public recreational spaces. All of these changes have made traditional opportunities to be physically active difficult to access. These changes have also exacerbated existing disparities in access to social and environmental supports for physical activity, potentially contributing to a widening gap in physical activity participation among those at greatest risk for COVID-19. Physical activity can play a special role in reducing the inequitable consequences of COVID-19; however, expansion and better targeting of evidence-informed interventions are needed that address the unique barriers present in communities that have been economically and socially marginalized to achieve health equity in COVID-19 outcomes. This review highlights effective and feasible strategies that provide more equitable access to physical activity programs and spaces across the United States. With a renewed investment in physical activity, this behavior can play a crucial role in improving population health and reducing disparities during the COVID-19 pandemic and beyond.

    Physical Activity Programming for Older Adults in Assisted Living: Residents’ Perspectives
    (Sage, 2023) Webster, Katelyn E.; Seng, Julia S.; Gallagher, Nancy A.; Gothe, Neha P.; Colabianchi, Natalie; Lavoie Smith, Ellen M.; Ploutz-Snyder, Robert; Larson, Janet L.; School of Nursing
    Decreasing sedentary behavior and increasing light physical activity could promote the maintenance of functional abilities for older adults in assisted living (AL). The purpose of this qualitative study was to gather residents' recommendations about a proposed self-efficacy enhancing intervention to replace sedentary behavior with light physical activity. We interviewed 20 residents (mean age 83.1; 60% women). Topics included their current activities and thoughts about physical activity. We presented the intervention and asked questions to inform its modification. Data were analyzed with content and thematic analysis. Specific recommendations included shorter one-hour sessions and framing the intervention as increasing light physical activity rather than decreasing sedentary behavior. The thematic analysis identified multiple factors that could influence intervention implementation, including motivation to be active, safety concerns, ageist attitudes about physical activity, varying abilities of residents, social influences, and limited opportunities for physical activity. These results will inform physical activity intervention implementation for AL residents.

    Prolonged Bouts of Sedentary Behavior in People with Chronic Obstructive Pulmonary Disease and Associated Factors
    (Elsevier, 2023) Webster-Dekker, Katelyn E.; Zhou, Weijiao; Woo, Seoyoon; Son, Jung Yoen; Ploutz-Snyder, Robert; Larson, Janet L.; School of Nursing
    Background: Increased sedentary behavior (SB), especially in prolonged bouts, is associated with adverse health outcomes, but little is known about patterns of SB in people with chronic obstructive pulmonary disease (COPD). Objectives: The purpose of this study was to describe SB and patterns of SB and to examine factors associated with prolonged bouts of SB in inactive community-dwelling adults with COPD. Methods: This cross-sectional analysis used data from inactive adults with COPD who were enrolled in an exercise program but had not started exercising. Participants were ≥ 50 years old with a diagnosis of COPD, had a forced expiratory volume in one second < 80% predicted, and were inactive. Participants wore an activPAL device for seven days to measure their SB and completed surveys and physical measures. Data were analyzed with multiple regression. Results: The sample included 160 participants with a mean age (± SD) of 69 ± 8, and a mean total sedentary time of 742 ± 150 min/day, with 254 ± 146 min/day in SB bouts ≥ 60 min. Duration: Time spent in bouts of SB ≥ 60-min. was negatively associated with self-efficacy for overcoming barriers to light physical activity (P<0.05), balance (P<0.05), chair stand test (P<0.05), FEV1% predicted (P<0.05) and positively associated with BMI (P<0.001). Conclusions: Inactive people with COPD engage in extensive SB, much of it in prolonged bouts. Self-efficacy, balance, and lower body strength are modifiable variables associated with SB and potential targets for future interventions to reduce time in prolonged sedentary behavior.
