Participatory developed school-based interventions targeting physical activity and sedentary behaviour among children and adolescents: A scoping review.

Aims: A significant number of children and adolescents are insufficiently physically active and have a sedentary lifestyle, which is associated with adverse health outcomes, necessitating effective interventions. Using a participatory approach, which engages youth in intervention development, may enhance intervention effectiveness, as such interventions are believed to be more tailored to the needs of the target group. This scoping review aimed to provide an overview of the results of process and effect evaluations of studies that developed school-based physical activity and/or sedentary behaviour interventions using a participatory approach among children and adolescents.

Navigating process evaluation in co-creation: a Health CASCADE scoping review of used frameworks and assessed components.

Background: Co-creation is seen as a way to ensure all relevant needs and perspectives are included and to increase its potential for beneficial effects and uptake process evaluation is crucial. However, existing process evaluation frameworks have been built on practices characterised by top-down developed and implemented interventions and may be limited in capturing essential elements of co-creation. This study aims to provide a review of studies planning and/or conducting a process evaluation of public health interventions adopting a co-creation approach and aims to derive assessed process evaluation components, used frameworks and insights into formative and/or participatory evaluation.

Preventing smoking initiation in adolescents living in vulnerable socioeconomic conditions: Study protocol of the KickAsh!-intervention.

Aims: Adolescents living in vulnerable socioeconomic conditions are confronted with tobacco-related health disparities. As school-based interventions appear to be less effective among these youngsters, other approaches are necessary. One promising avenue is youth social work settings that offer sport and recreational activities (SR-settings).

Associations of habitual sedentary time with executive functioning and short-term memory in 7th and 8th grade adolescents.

Background: While there is increasing evidence for negative physical health consequences of high volumes of sedentary time and prolonged sedentary time in adolescents, the association with cognition is less clear. This study investigated the association of volumes of habitual sedentary time and prolonged sedentary time with executive functions and short-term memory in adolescents.

Methods: This study has a cross-sectional observational study design.

Combining participatory action research with intervention mapping to develop and plan the implementation and evaluation of a healthy sleep intervention for adolescents.

Background: Adolescents' sleep deteriorated over the last decades, urging the need to develop effective interventions.

Therefore, this study investigates whether changes in knowledge about healthy sleep, attitude toward healthy sleep and going to bed on time, self-efficacy to engage in healthy sleep behavior, perceived parental and peer norms, perceived barriers (e.g.

Smoking prevention within social work organizations: a qualitative study about youngsters' and youth workers' perceptions.

Tobacco smoking uptake is still a major public health concern, especially among youngsters living in vulnerable situations. Finding optimal ways to engage youngsters in smoking prevention is important. Compared to traditional settings such as schools, social work settings providing sports-based and recreational activities (SR-settings) tend to reach and engage youngsters more.

Dissemination, Implementation, and Evaluation of an Effective School-Based Intervention to Promote Physical Activity in Adolescents: A Study Protocol.

Adolescents around the world do not engage in sufficient physical activity and the Spanish context is no exception. Understanding the educational context as a complex system, school-based multi-level and multi-component interventions seem to be an effective strategy to reverse this trend. Moreover, a co-creational approach seems to facilitate the mobilization of community partnerships and the engagement of stakeholders in the intervention process.

Does an obesogenic family environment moderate the association between sports participation and body composition in children? The ENERGY project.

Background: Previous research on the association between sports participation and body composition has shown mixed findings. The family home is considered one of the most influential environments on childhood obesity. Thus, the association between sports participation and body composition in children may be influenced by an obesogenic home environment.

Co-creating an intervention to promote physical activity in adolescents with intellectual disabilities: lessons learned within the Move it, Move ID!-project.

Background: Co-creation is a method to develop acceptable, contextually appropriate and potentially more effective interventions. Adolescents with intellectual disabilities (ID) seldomly participate in research and program development due to the assumption that they lack the capacity to understand and discuss the related topics.

Objective: This study describes reflections on a co-creation process with adolescents with ID from the point of view of the researchers in developing an intervention to increase physical activity.

Psychosocial factors related to sleep in adolescents and their willingness to participate in the development of a healthy sleep intervention: a focus group study.

Background: Over the last decades, adolescents' sleep has deteriorated, suggesting the need for effective healthy sleep interventions. To develop such interventions, it is important to first gather insight into the possible factors related to sleep. Moreover, previous research has indicated that chances of intervention effectivity could be increased by actively involving adolescents when developing such interventions.

Bidirectional associations between sedentary time and sleep duration among 12- to 14-year-old adolescents.

Background: The aim of this study was to investigate bidirectional associations between (prolonged) sitting time and sleep duration in 12- to 14-year-old adolescents using a between-subjects and within-subjects analyses approach.

Which behaviour change techniques are effective to promote physical activity and reduce sedentary behaviour in adults: a factorial randomized trial of an e- and m-health intervention.

Background: E- and m-health interventions are promising to change health behaviour. Many of these interventions use a large variety of behaviour change techniques (BCTs), but it's not known which BCTs or which combination of BCTs contribute to their efficacy. Therefore, this experimental study investigated the efficacy of three BCTs (i.

Validity of Items Assessing Self-Reported Number of Breaks in Sitting Time among Children and Adolescents.

: Sedentary behaviour guidelines recommend that individuals should regularly break up sitting time. Accurately monitoring such breaks is needed to inform guidelines concerning how regularly to break up sitting time and to evaluate intervention effects. We investigated the concurrent validity of three "UP4FUN child questionnaire" items assessing the number of breaks in sitting time among children and adolescents.

Public health communication and education to promote more physical activity and less sedentary behaviour: Development and formative evaluation of the 'physical activity triangle'.

Objective: Communication and education about health behaviours to the general population is essential in public health promotion. This paper describes the process and outcome of developing a new health education model (infographic) for physical activity (PA) and sedentary behaviour used in Flanders (Belgium).

Methods: The Flanders Institute for Healthy Living, expertise centre for public health, coordinated a process, including the evaluation of its previous education model among citizens; reviewing existing models from other countries; expert panel meetings (n = 3); and a formative evaluation (34 focus groups) among citizen with various profiles.
