  • The Differential Associations Between Passive and Interactive Screentime and Sleep Duration Among 8th and 11th Grade Adolescents

    Open AccessChristopher D Pfledderer, Nalini Ranjit et al.ARTICLEChildren2026

    Background: Although several studies have reported associations between screentime and shortened sleep duration among adolescents, contextual relationships between different forms of screentime are not well understood. The purpose of this study was to examine how television (TV) watching (passive media use) and video/computer gaming (interactive media use) are associated with short sleep duration among 8th and 11th grade adolescents. Methods: We …

  • Barriers and facilitators to structured, out-of-school physical activity participation among rural youth in the United States

    Open AccessAshleigh M Johnson, Albert W Johnson et al.ARTICLEBMC Public Health2026

    Barriers to physical activity (PA) participation affect United States (US) youth’s ability to meet PA guidelines. There is evidence showing lower PA among rural versus urban youth due to fewer PA opportunities and resources. Out-of-school programs can help reduce geographic disparities in PA, but there is a dearth of literature on participation factors among rural youth. This study aimed to identify, describe, and synthesize peer-review literatur…

  • Differences in children’s food and beverage consumption between school and summer

    Open AccessMichael W Beets, Sarah Burkart et al.ARTICLEBMC Public Health2025

    Children were less likely to report consumption of healthier foods/beverages and more likely to report consumption of unhealthier foods/beverages during summer compared to school. Attending structured programming during summer is associated with improved diet- suggesting such settings have potential to modify dietary intake

  • Feasibility and acceptability of an implementation strategy to enhance use of classroom-based physical activity approaches in elementary schools

  • Examining associations between physical activity context and children meeting daily physical activity guidelines

    Open AccessChristopher D Pfledderer, Denver M Y Brown et al.ARTICLEFrontiers in Public Health2024

    Background: Less than one-quarter of US children meet physical activity (PA) guidelines. Understanding the context in which PA occurs and how these contexts may play a role in meeting PA guidelines is an essential step toward developing effective behavioral interventions. The purpose of this study was to examine associations between PA context (sports participation, participation in other organized physical activities, active travel to school, an…

  • Elementary school staff perspectives on the implementation of physical activity approaches in practice

    Open AccessTimothy J Walker, Christopher D Pfledderer et al.ARTICLEFrontiers in Public Health2023

    Introduction A whole-of-school approach is best to promote physical activity before, during, and after school. However, multicomponent programming is often complex and difficult to deliver in school settings. There is a need to better understand how components of a whole-of-school approach are implemented in practice. The objectives of this mixed methods study were to: (1) qualitatively explore physical activity approaches and their implementatio…

  • Observed and perceived benefits of providing physical activity opportunities in elementary schools

    Open AccessTimothy J Walker, Derek W Craig et al.ARTICLEFrontiers in Sports and Active…2023References: 3

    Introduction Schools play an important role in promoting physical activity for youth. However, school-based physical activity opportunities often compete with other academic priorities, limiting their implementation. The purpose of this study was to qualitatively explore elementary school teacher and staff perspectives on providing physical activity opportunities and how they impact students and learning. Methods We partnered with a school distri…

  • Impact of Virtual vs. In-Person School on Children Meeting the 24-h Movement Guidelines during the Covid-19 Pandemic

    Open AccessChristopher D Pfledderer, Michael W Beets et al.ARTICLEInternational Journal of…2022

    The pandemic mitigation strategy of closing schools, while necessary, may have unintentionally impacted children's moderate-to-vigorous physical activity (MVPA), sleep, and time spent watching screens. In some locations, schools used hybrid attendance models, with some days during the week requiring in-person and others virtual attendance. This scenario offers an opportunity to evaluate the impact of attending in-person school on meeting the 24-h…

  • Parent and Child Perceptions of Barriers to Active School Commuting

    Open AccessChristopher D Pfledderer, Ryan D Burns et al.ARTICLEJournal of School Health2021

    BACKGROUND: Active commuting (AC) to and from school can contribute to physical activity, although it has recently seen a global decline. The purpose of this study was to examine the agreement between parent and child perceptions of barriers to school AC. METHODS: = 10.0 ± 1.2 years). School commute type/frequency and barriers to AC were collected via surveys. Intraclass correlation coefficients (ICCs) were used to assess relative agreement betwe…

  • Familial Factors Associating with Youth Physical Activity Using a National Sample

    Open AccessRyan D Burns, Taylor E Colotti et al.ARTICLEChildren2020

    The purpose of this study was to examine the associations of familial and child-related factors with reported child physical activity using a representative sample of US children and adolescents. Data were analyzed from the combined 2017-2018 National Survey of Children's Health. Household addresses were randomly selected within each US state. One parent within each household answered health and wellness questions pertaining to one randomly selec…

  • Movement Behaviors and Perceived Loneliness and Sadness within Alaskan Adolescents

    Open AccessRyan D Burns, Yang Bai et al.ARTICLEInternational Journal of…2020

    Physical activity, screen use, and sleep are behaviors that integrate across the whole day. However, the accumulative influence of meeting recommendations for these 24-h movement behaviors on the mental health of Alaskan adolescents has not been examined. The purpose of this study was to examine the associations between movement behaviors, loneliness, and sadness within Alaskan adolescents. Data were obtained from the 2019 Alaska Youth Risk Behav…

  • Association between Access to Electronic Devices in the Home Environment and Cardiorespiratory Fitness in Children

    Open AccessChristopher D Pfledderer, Ryan D Burns et al.ARTICLEChildren2019

    This study examined the association between access to electronic devices in the home and cardiorespiratory fitness in children. Participants were children aged 8−12 years from a local elementary school ( n = 106, mean age = 9.7 + 1.1 years, male = 50). Child access to electronic devices was measured with a 37-item parent-reported questionnaire. Estimated maximal aerobic capacity (VO 2 Peak ) was calculated from The Progressive Aerobic Cardiovascu…
