Promoting ball-based play and sports participation for preschool children
Introduction This study investigates the effects of a preschool intervention, Ball-based Play in Preschool , on two primary outcomes: children's participation in ball-based leisure sports and a composite index of enjoyment, skill level, and frequency of ball-based play. Secondary descriptive analyses examine the distribution of these outcomes and their associations with background characteristics. Methods The intervention was developed to integra…
Adapting a resistance training program for Danish physical education
Introduction Transferring and scaling school-based physical activity (PA) programs across educational contexts requires systematic adaptation to ensure implementation feasibility and contextual fit. This study examined Danish physical education (PE) teachers' preconceptions for resistance training and a participatory co-adaptation process used to adapt the evidence-based Resistance Training for Teens (RT4T) program for implementation in Danish lo…
Maintaining conceptual fidelity through teacher-led adaptation
School-based physical activity programs are widely promoted to address adolescent physical inactivity, yet their population-level impact is often limited by implementation challenges in real-world school settings. While implementation fidelity is frequently assessed, less is known about how teachers actively balance adherence and local adaptation while maintaining core program principles. This study examined the implementation of the FIT FIRST Te…
The FIT FIRST 10 dose-response study
Introduction Increasing physical activity (PA) levels among children is critical to mitigate health risks associated with physical inactivity. Schools have been highlighted as ideal setting for promoting PA. However, existing school-based PA programs often face implementation challenges. The FIT FIRST 10 (FF10) multi-sport program has been introduced in Denmark, aiming to increase PA and to enhance children's health, fitness, and well-being. This…
Exploring the Role of Champions in the Facilitation and Implementation of a Whole-School Health Program
The aim of this article is to explore the role of local school champions in the facilitation and implementation of “The School Health Program”. This study is based on semi-structured interviews with 26 local school champions. The interviews focused on exploring key implementation responsibilities and barriers and facilitators to implement core program components. Champions identify coordination, promotion, and handling of support functions as key…
A comparative analysis of movement and physical activity in early childhood teacher education policy in five Nordic countries
Introduction The aim of this study is to investigate the integration of movement and physical activity (MoPA) within Early Childhood Teacher Education (ECTE) policies across Denmark, Finland, Iceland, Norway, and Sweden. This knowledge can inform the development of ECTE policies and practices that promote MoPA in Early Childhood Education and Care (ECEC) in Nordic countries and other countries worldwide. Methods In this study, a Nordic cross-nati…
Cross-country adaptation and feasibility of an evidence-based resistance training intervention in the school setting
Background Physical activity that strengthens muscles and bones at least three times per week are recommended, but few adolescents meet this target. The aim of our study was to adapt and evaluate the feasibility and preliminary efficacy of the Resistance Training for Teens (RT4T) program in Danish lower secondary schools. Methods Developed and evaluated in Australia, the aim of RT4T is to provide adolescents with competence, confidence, knowledge…
Device-based physical activity measures for population surveillance—issues of selection bias and reactivity
Recruiting a population representative sample for device-based measurement of physical activity is challenging, and there is a substantial risk of sample selection bias and measurement reactivity. Further research in this area is needed if device-based measures should be considered for population physical activity surveillance
Global Matrix 4.0 Physical Activity Report Card Grades for Children and Adolescents
Background : The Global Matrix 4.0 on physical activity (PA) for children and adolescents was developed to achieve a comprehensive understanding of the global variation in children’s and adolescents’ (5–17 y) PA, related measures, and key sources of influence. The objectives of this article were (1) to summarize the findings from the Global Matrix 4.0 Report Cards, (2) to compare indicators across countries, and (3) to explore trends related to t…
A Qualitative Exploration of Implementation, Adaptation, and Sustainability of a School-Based Physical Activity Intervention
School-based physical activity can promote health and improve learning outcomes, but efforts to increase school physical activity have had limited success. This study evaluates the sustainability of a multicomponent school-based physical activity intervention and identifies important factors for implementation and sustainability. Results are based on focus group interviews with 18 teachers at five implementing schools 10 months after the terminat…
Built Environment, Physical Activity, and Obesity
Creating more physical activity–supportive built environments is recommended by the World Health Organization for controlling noncommunicable diseases. The IPEN (International Physical Activity and Environment Network) Adult Study was undertaken to provide international evidence on associations of built environments with physical activity and weight status in 12 countries on 5 continents ( n > 14,000). This article presents reanalyzed data from e…
Variations in accelerometry measured physical activity and sedentary time across Europe – harmonized analyses of 47,497 children and adolescents
Do physical activity and sedentary time mediate the association of the perceived environment with BMI? The Ipen adult study
Pupils’ experiences of autonomy, competence and relatedness in ‘Move for Well-being in Schools’
Physical activity at school can be beneficial to children’s psychosocial well-being. To realise this potential, a school environment that supports physical activity is crucial. Self-Determination Theory provides the basis for one approach, namely to focus on pupils’ need to feel competent, autonomous and related. The purpose of this study was to investigate how pupils experienced a school physical activity intervention based on Self-Determination…
Objectively-assessed neighbourhood destination accessibility and physical activity in adults from 10 countries
Access to parks and physical activity
International comparisons of the associations between objective measures of the built environment and transport-related walking and cycling
Improving the well-being of children and youths
The benefits of physical activity for the mental health and well-being of children and young people are well-established. Increased physical activity during school hours is associated with better physical, psychological and social health and well‐being. Unfortunately many children and young people exercise insufficiently to benefit from positive factors like well-being. The main aim of this study is to develop, implement and evaluate a multi-comp…
Moderating effects of age, gender and education on the associations of perceived neighborhood environment attributes with accelerometer-based physical activity
International variation in neighborhood walkability, transit, and recreation environments using geographic information systems
BACKGROUND: The World Health Organization recommends strategies to improve urban design, public transportation, and recreation facilities to facilitate physical activity for non-communicable disease prevention for an increasingly urbanized global population. Most evidence supporting environmental associations with physical activity comes from single countries or regions with limited variation in urban form. This paper documents variation in compa…
Sharing good News across the world
We have proposed country-specific modifications to the original scoring protocol of the NEWS/NEWS-A that enhance inter-country comparability. These modifications have yielded sufficiently equivalent measurement models of the NEWS/NEWS-A. Some inter-country discrepancies remain. These need to be considered when interpreting findings from different countries
