Background: A mismatch between organizational priorities and system-level policies can negatively impact implementation and sustainment of classroom-based physical activity (PA) interventions. The purpose of this study was twofold: (1) present methods to systematically identify organization- and system-level implementation barriers, and (2) align…

Background: This study evaluated stakeholders' perceptions regarding the initial implementation process of the health promoting school model proposed by the affordable health initiative (AHI HPS model) in schools of Belo Horizonte/BRA. Methods: The model has been implemented since 2019, by an implementation committee (IC) with members from…

Background: This study assessed the effects of the "Jump-in" whole-school intervention in Amsterdam, the Netherlands, on children's weight development by comparing children exposed to the intervention and controls from 3 other large Dutch cities. Jump-in is a comprehensive intervention that aims to stimulate healthy nutrition and…

Background: School-based dental sealant programs are noted to increase sealant uptake among children, especially those from low-income families and those living in rural and underserved areas. However, nationally school-based dental sealant programs are substantially underutilized. This paper describes a partnership approach to a school-based…

Background: Evidence-based comprehensive physical activity programs developed for public schools are abundant yet a theoretical framework for implementation of these programs is lacking. Implementation science in public service organizations is an emerging area of research, but has not been widely successful in the area of physical activity…

Background: School-based physical activity (PA) programs are an equitable, evidence-based approach to combat health and PA disparities. This study examined factors associated with implementation of BE Physically Active 2Day (BEPA 2.0), a K-5 school-based PA program, and examined how support from Cooperative Extension via Supplemental Nutrition…

Background: School-based interventions and strategies targeting physical activity (PA) and eating patterns have successfully addressed unhealthy behaviors contributing to excess weight in school-age children. The purpose of this study was to investigate South Carolina (SC) public school administrators' perceptions of and experiences with…

Background: School-level implementation of district-level local wellness policies (LWPs) is needed to create school environments that promote nutrition and physical activity (PA). Disparities in classroom-specific LWPs implementation were examined. Methods: administrator survey (N = 756 schools; 24/24 districts) included 6 classrooms LWP…

Background: In this systematic review, we assessed the existing research describing the effects of physical activity (PA) on academic behavior, with a special focus on the effectiveness of the treatments applied, study designs, outcome measures, and results. Methods: We obtained data from various journal search engines and 218 journal articles…

Background: After-school programs (ASPs) have the potential to contribute to student physical activity (PA), but there is limited empirical evidence to guide program development and implementation. Methods: We used pedometry to assess the overall effectiveness of an elementary school ASP running program relative to national and state PA…

Background: Declines in physical activity (PA) in children and youth have contributed to increases in childhood overweight and obesity. The Safe Routes to School (SRTS) program was developed to promote school active transportation (AT) and reverse the trend. Methods: Adopting concepts of a realist approach, this article seeks to understand…

Background: Preschool settings vary greatly, and research has shown that interventions are more successful when they can be adapted to individual settings. This is a descriptive case study of how 2 teachers successfully adapted and implemented a preschool physical activity intervention. Methods: The Study of Health and Activity in Preschool…

Background: Measuring the implementation of school-based physical activity (PA) interventions is an important prerequisite in assessing their impact. Prior to conducting a study to assess the implementation of the daily physical activity (DPA) policy in Ontario, Canada, a literature review was conducted to identify existing survey instruments to…

Background: The school environment has the potential to influence student body mass index (BMI) through programs and policies. Our objective was to examine the effect of modifying obesity-related school policies and programs on youths' BMI trajectories. Methods: Obesity-related school policies and programs related to physical activity and healthy…

Background: We examined the impact of the Fuel Up to Play 60 (FUTP60) program on children's body mass index (BMI) and aerobic capacity (AC). Methods: Participation in the FUTP60 and both BMI and AC profiles were collected through the NFL PLAY 60 FitnessGram Partnership Project involving over 100 schools from 22 US states. We specifically examined…
