Assessing the impact of COVID-19 on the physical activity of 10-11-year-old children and their parents: Active-6 a mixed-methods study.

Background: Physical activity is essential for long-term health, yet data from before the COVID-19 pandemic showed only 41% of 10- to 11-year-olds met the UK government's physical activity recommendations. Children's physical activity was limited during the national COVID-19 lockdowns. It is important to measure children's physical activity in the recovery period to assess the short- and medium-term impact of the lockdowns.

A service evaluation of the uptake and effectiveness of a digital delivery of the NHS health check service.

Objectives: To compare the uptake, effectiveness and costs of a digital version of the National Health Service (NHS) Health Check (DHC) to the standard face-to-face NHS Health Check (F2F).

Participants And Setting: A random sample of 9000 patients aged 40-74 eligible for an NHS Health Check in Southwark, England, between January and April 2023.

Intervention And Design: The DHC was an online tool with a health assessment section, an advice and support section, and a section on how to obtain and update follow-up physical measures (blood pressure, cholesterol, glycated haemoglobin (HbA1c)).

School-level variation in children's moderate to vigorous intensity physical activity before and after COVID-19: a multilevel model analysis.

Background And Objectives: Schools play a crucial role in facilitating physical activity among children, but the COVID-19 pandemic has affected both children's physical activity and the school environment. It is essential to understand between-school differences in children's physical activity post lockdown, to determine if and how the role of schools has changed.

Design And Participants: Active-6 is a natural experiment comparing postlockdown accelerometer-estimated physical activity to a pre-COVID-19 comparator group.

Development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS).

Background: Teachers are recognized as 'key agents' for the delivery of physical activity programs and policies in schools. The aim of our study was to develop and evaluate a tool to assess teachers' capability, opportunity, and motivation to deliver school-based physical activity interventions.

Methods: The development and evaluation of the Capability, Opportunity, and Motivation to deliver Physical Activity in School Scale (COM-PASS) involved three phases.

Ultra-processed food consumption in UK adolescents: distribution, trends, and sociodemographic correlates using the National Diet and Nutrition Survey 2008/09 to 2018/19.

Purpose: We quantified levels of ultra-processed food (UPF) consumption and investigated consumption patterns in a representative sample of UK adolescents.

Methods: We used data from 4-day food diaries from adolescents in the UK National Diet and Nutrition Survey (NDNS) (2008/09-2018/19). UPF were identified using the NOVA classification.

Consolidated guidance for behavioral intervention pilot and feasibility studies.

Background: In the behavioral sciences, conducting pilot and/or feasibility studies (PFS) is a key step that provides essential information used to inform the design, conduct, and implementation of a larger-scale trial. There are more than 160 published guidelines, reporting checklists, frameworks, and recommendations related to PFS. All of these publications offer some form of guidance on PFS, but many focus on one or a few topics.

Co-designing adult weight management services: a qualitative study exploring barriers, facilitators, and considerations for future commissioning.

Background: Weight management services have not always benefitted everyone equally. People who live in more deprived areas, racially minoritised communities, those with complex additional needs (e.g.

Are the Risk of Generalizability Biases Generalizable? A Meta-Epidemiological Study.

Background: Preliminary studies (e.g., pilot/feasibility studies) can result in misleading evidence that an intervention is ready to be evaluated in a large-scale trial when it is not.

Graded exercise therapy compared to activity management for paediatric chronic fatigue syndrome/myalgic encephalomyelitis: pragmatic randomized controlled trial.

The MAGENTA pragmatic parallel groups randomized controlled trial compared graded exercise therapy (GET) with activity management (AM) in treating paediatric myalgic encephalomyelitis or chronic fatigue syndrome (ME/CFS). Children aged 8-17 years with mild/moderate ME/CFS and presenting to NHS specialist paediatric services were allocated at random to either individualised flexible treatment focussing on physical activity (GET, 123 participants) or on managing cognitive, school and social activity (AM, 118 participants) delivered by NHS therapists. The primary outcome was the self-reported short-form 36 physical function subscale (SF-36-PFS) after 6 months, with higher scores indicating better functioning.

Study protocol for the Screen-Free Time with Friends Feasibility Trial.

Background: Children are spending less leisure time with their friends in person and an increasing amount of time with digital screens. These changes may negatively affect children's physical and mental health. The Screen-Free Time with Friends Feasibility Trial will test the feasibility, including acceptability and compliance, of an intervention designed to reduce screen media usage and encourage physical interaction with friends during leisure time in 9-11-year-old children.

Effectiveness of the Walking in ScHools (WISH) Study, a peer-led walking intervention for adolescent girls: results of a cluster randomised controlled trial.

Background: Most adolescent girls fail to meet current physical activity guidelines. Physical activity behaviours track from childhood into adulthood and providing adolescent girls with opportunities to be physically active may have health benefits beyond childhood. The effects of walking interventions on adult cardiometabolic health are known, however less is understood about the potential of walking to promote physical activity in adolescents.

The impact of the COVID-19 pandemic on the physical activity environment in English primary schools: a multi-perspective qualitative analysis.

Background: The COVID-19 lockdowns and social distancing measures, including school closures, had a major impact on children's physical activity in England, with data showing an initial reduction in activity in the short-term post-lockdown phase of the pandemic followed by a recovery on average in the medium-term post-lockdown period. The school environment is an important context for child physical activity. The purpose of this study is to understand the changes that took place to school physical activity environments once schools reopened after lockdowns.

Expert Perspectives on Pilot and Feasibility Studies: A Delphi Study and Consolidation of Considerations for Behavioral Interventions.

Background: In the behavioral sciences, conducting pilot and/or feasibility studies (PFS) is a key step that provides essential information used to inform the design, conduct, and implementation of a larger-scale trial. There are more than 160 published guidelines, reporting checklists, frameworks, and recommendations related to PFS. All of these publications offer some form of guidance on PFS, but many focus on one or a few topics.

A peer-led walking intervention for adolescent girls (the WISH study): a cluster-randomised controlled trial.

Background: Adolescent girls in the UK and Ireland fail to meet physical activity (PA) guidelines. PA behaviours track from childhood into adulthood. The effects of walking interventions on adult health are known; however, the potential of walking to promote PA in adolescents is less known.

How Do You Move? Everyday stories of physical activity.

Stories can be a powerful method of exploring complexity, and the factors affecting everyday physical activity within a modern urban setting are nothing if not complex. The first part of our How Do You Move? study focused on the communication of physical activity guidelines to under-served communities. A key finding was that adults especially wanted physical activity messages to come from 'everyday people, people like us'.

'Including us, talking to us and creating a safe environment'-Youth patient and public involvement and the Walking In ScHools (WISH) Study: Lessons learned.

Background: Young people have the right to be informed and consulted about decisions affecting their lives. Patient and public involvement (PPI) ensures that research is carried out 'with' or 'by' young people rather than 'to', 'about' or 'for' them. The aim of this paper is to outline how youth PPI can be embedded within a physical activity intervention, reflect on the impact of PPI and provide recommendations for future PPI in a similar context.
