Exploring Context-specific Physical Activity and Sedentary Behavior Patterns Among Youth Enrolled in Kansas 4-H Programming

Denver M. Y. Brown, Peter Stoepker, Greg J. Welk

Purpose To characterize context-specific patterns of moderate-to-vigorous physical activity (MVPA) and sedentary behavior among Kansas youth in 4-H programming, and to examine differences and interactions by gender, grade, and urban/rural status. Design Cross-sectional, observational survey. Setting Online survey administered in April-May 2025 …

Feasibility of Consumer Wearable–Based Physical Activity Monitoring Across the School–Summer–School Transition in Middle School Students: A 208-Day Prospective Cohort Study (Preprint)

Denver M. Y. Brown, Sam Kendig, Carah D. Holesovsky, Keith Brazendale et autres

BACKGROUND Consumer wearables could enable continuous assessment of adolescents’ physical activity (PA) across school and summer periods, overcoming limitations of studies that rely on brief assessments at selected time points. However, little is known about whether sufficient data completeness can be maintained …

Promoting Active Schools in the United States: A Feasibility Study Applying the Interactive Systems Framework

Taemin Ha, Peter Stoepker, Gregory Welk, Brian D. Dauenhauer

PurposeThis feasibility study explored the application of the Interactive Systems Framework for Dissemination and Implementation (ISF) to promote physical activity (PA) in elementary schools, leveraging resources from Active Schools.ApproachA convergent parallel mixed-methods design was used to examine implementation efforts and student PA …

OST-Coach: Impact of a Data-Coaching Process on Staff Physical Activity Promoting Behavior

Katie Schwartzkopf, Sarah Arraiga, Emily L. Mailey, Denver M. Y. Brown et autres

The purpose of this study was to implement a data-coaching process to address staff PA-promoting behaviors during out-of-school time (OST) programming. This single-group pre-post study involved OST programs across four elementary schools. An iterative data-coaching program (OST-Coach) was implemented that addressed staff …

Beyond the Guidelines: Exploring the Prevalence and Correlates of No-to-Low Moderate to Vigorous Physical Activity Among US Adolescents

Denver M. Y. Brown, Christopher D. Pfledderer, Sitong Chen, Peter Stoepker et autres

BACKGROUND: Although many studies examine adolescent physical activity (PA) guideline adherence, few focus on the lowest end of the PA spectrum-engaging in no-to-low moderate to vigorous PA (MVPA). METHODS: This study characterized cross-sectional and longitudinal patterns of device-measured no-to-low MVPA among a …

Device-independent Physical Activity metrics and adiposity-related indicators among children and adolescents in the United States

Denver M. Y. Brown, Christopher D. Pfledderer, Peter Stoepker, Kar Hau Chong et autres

This study investigated associations between device-independent physical activity (PA) metrics and adiposity-related indicators among U.S. children and adolescents. Nationally representative cross-sectional data from three NHANES cycles (2011–2014) were analyzed, including 5,274 participants (weighted n = 43,156,858; 49.3% female; ages 6–17 years) who …

Considerations in using heart rate-based physical activity estimates from consumer wearables in individuals with varying weight status

Denver M. Y. Brown, David Wing, Christopher D. Pfledderer, Peter Stoepker et autres

Although moderate-to-vigorous physical activity (MVPA) is a widely used construct in physical activity (PA) research, the lack of standardized assessment methods- particularly with the growing use of consumer-grade wearable activity trackers- poses challenges for comparability. Consumer-grade devices tend to rely on heart …

The Integration of a Data Sharing Process to Address Out-of-School Time Physical Activity, Locomotor Skills, and Program Leader Behavior: A Pilot Study

Peter Stoepker, Duke Biber, Brian D. Dauenhauer, Chelsea Steel et autres

Children are not meeting the physical activity (PA) minutes recommendation. Due to this, new and innovative approaches are needed to address child inactivity. Motor competence is associated with PA and fitness in children, and could potentially be targeted to increase child PA. …

Exploring Context-Specific Physical Activity and Sedentary Behavior Patterns Among Youth Enrolled in Kansas 4-H Programming

Denver M. Y. Brown, Peter Stoepker, Gregory J. Welk

Understanding how physical activity (PA) and sedentary behavior (SB) vary by age, gender, and geographic context is essential to inform targeted public health strategies. This study characterized context-specific patterns of moderate-to-vigorous PA (MVPA) and SB among Kansas youth participating in 4-H programming. …

Well-being inequities in eleven rural Georgia communities: A latent profile analysis

April K. Hermstad, Regine Haardöerfer, Kimberly Jacob Arriola, Peter Stoepker et autres

Personal well-being is a broad term that encompasses life domains that are not strictly health related, including social, emotional, financial, and environmental factors. Well-being is highly correlated with a range of sociodemographics and health outcomes. Little is known about well-being in rural …
