ObjectivesCOVID-19 restrictions reduced adolescents’ opportunities for physical activity (PA). The purpose of this study was to examine how adolescent PA changed during school closures, to identify the key barriers and facilitators for these changes during lockdown and to use this information to understand how to manage future crises’ situations positively to prevent physical inactivity.MethodsIrish adolescents (N=1214; ages 12–18 years) participated in an online cross-sectional study during April 2020, including items on PA level, changes in PA and reasons for change in an open-ended format. Numeric analyses were through multiple binary logistic regressions, stratified by changes in PA during lockdown and inductive analysis of open coding of text responses.ResultsAdolescents reported they did less PA (50%), no change (30%) or did more PA during lockdown (20%). Adolescents who did less PA were more likely to be overweight (OR=1.8, CI=1.2–2.7) or obese (OR=2.2, CI=1.2–4.0) and less likely to have strong prior PA habits (OR=0.4, CI=0.2–0.6). The most cited barriers to PA were coronavirus, club training cancelled and time. Strong associations for doing more PA included participation in strengthening exercises at least three times in the past 7 days (OR=1.7, CI=1.3–2.4); facilitators were more time, coronavirus and no school.ConclusionCOVID-19 restrictions were both a barrier to and an opportunity for PA. Parents, schools, public health, communities and industries must collaborate to prevent physical inactivity at times of crisis, especially for vulnerable groups.

Background. Low levels of physical activity (PA) in adolescents highlight the necessity for effective intervention. During adolescence, peer relationships can be a fundamental aspect of adopting and maintaining positive health behaviors. Aim. This review aims to determine peer-led strategies that showed promise to improve PA levels of adolescents. It will also identify patterns across these interventions, including training provided and the behavior change techniques (BCTs) employed. Method. Adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, PubMed, PsychINFO, and Scopus were searched using key concepts of peer, PA and adolescent for articles that examined interventions that had a peer-led component and reported on at least one PA outcome in 12- to 19-year-olds. Following title and abstract screening of 1,509 studies, and full text review stage, 18 progressed to data synthesis. Methodological quality was assessed using an adapted scale. Results. Quality assessment identified 11 studies as high quality. Half of the included studies ( n = 9) reported improved PA outcomes in the school setting. The most prominent behavioral change techniques were social support, information about health consequences, and demonstration of the behavior. Older adolescents leading younger peers and younger adolescents leading those of the same age showed potential. Seldom have older adolescents been targeted. Gender-specific interventions showed the most promise. Conclusion. Peer leadership requires careful planning and in the school setting can be a resourceful way of promoting adolescent PA.

Taking part in regular physical activity (PA) is important for young adolescents to maintain physical, social and mental health. Schools are vibrant settings for health promotion and the complexity of driving a whole-school approach to PA has not been tested in the Irish school context. The feasibility of the pilot programme of the Department of Education and Skills second level Active School Flag (SLASF) is needed. SLASF is a two year process that consists of the Active School Flag (ASF) certificate programme (year 1) and the ASF flag programme (year 2). This protocol paper is specific to the first year certificate process. Three schools around Ireland were recruited as pilot schools to carry out the year-long SLASF programme with 17 planned actions involving the entire school. Students in the transition year programme have a particular role in the promotion of PA in SLASF. Data collection consists of physical measures, accelerometers, survey data and interviews at the beginning and the end of the academic year. The primary focus on the feasibility of the programme is through process evaluation tools and fidelity checks consisting of implementation of the SLASF programme through whole-school surveys, focus group discussions of key stakeholder groups, as well as one-to-one interviews with a member of management at each school and the SLASF coordinator of the school. Secondary outcomes include PA levels and its social cognitive theories based correlates through physical health measures, surveys carried out pre- and post-intervention, as well as focus group discussions of the students. The results of this study are needed to improve the development of the SLASF through a predetermined stopping criteria and inclusion into systems thinking approaches such as the Healthy Ireland Demonstration Project.

Summary Whole-of-school programmes (WSPs) are recommended to promote physical activity for adolescents. The Active School Flag (ASF) programme for secondary-level schools is one such WSP. Due to the difficulties of incorporating WSPs into the complex school system, there is a risk of poor implementation. The monitoring of unanticipated influences can help to understand key implementation processes prior to scale-up. The aims of this study were to identify perceived facilitators and barriers to implementing the ASF and recommend evidence-based implementation strategies. Focus groups and interviews (N = 50) were conducted in three schools with stakeholders involved in programme implementation, i.e. school management (n = 5), ASF coordinator (n = 4), student-leaders (aged 15–16 years) (n = 64) and staff committee (n = 25). Transcripts were analysed using codebook thematic analysis and were guided by the Consolidated Framework for Implementation Research. Implementation strategies were identified and were selected systematically to address contextual needs. Three themes surrounding the facilitators and barriers to implementation were generated: intervention design factors (e.g. capacity building and knowledge of implementers; and interest and buy-in for the programme), organizational factors (e.g. optimization of people and the busy school environment) and interpersonal factors (e.g. communication and collaboration). The examination of facilitators and barriers to implementation of the ASF has assisted with the identification of implementation strategies including (not limited to) a shared leadership programme for student leaders and a more flexible timeline for completion. These facilitative implementation strategies may assist in the effective implementation of the ASF.
