Association between 24-hour movement behaviors and adiposity in children and adolescents: A compositional data meta-analysis.

Purpose: To quantitatively synthesize published evidence on the association between 24-hour movement behavior composition with adiposity in children and adolescents aged 3-18 years.

Methods: Systematic literature searches were conducted in five electronic databases to identify papers published between January 2015 and January 2024. A machine learning-assisted systematic review was conducted to identify studies applying compositional data analysis to examine the association between 24-hour movement behaviors and adiposity in children and youth.

Parental use of routines, setting limits, and child screen use during COVID-19: findings from a large Canadian cohort study.

Background: An increase in child screen time has been observed throughout the COVID-19 pandemic. Home environment and parenting practices have been associated with child screen time. The purpose of this study was to examine associations between parental use of routines, limit setting, and child screen time during the (COVID-19) pandemic to inform harm-reducing strategies to limit the potential harms ensued by excessive screen use.

Early childhood body mass index growth and school readiness: A longitudinal cohort study.

Background: Child growth influences future health and learning. School readiness refers to a child's ability to meet developmental expectations at school entry. The association of early growth rate and patterns with school readiness remains unknown.

Associations Between Childcare Physical Activity and Sedentary Time and Early Childhood Developmental Outcomes: A Compositional and Isotemporal Substitution Analysis.

Background: Physical activity and sedentary time are independently associated with health and developmental outcomes in preschool children. However, the integrated nature of these behaviours on early life outcomes, particularly during childcare hours, is currently understudied. As such, the aim of this study was to examine the association between preschool children's physical activity and sedentary time during childcare and various developmental outcomes (psychosocial, cognitive and fundamental movement skills).

Are Experiences of Discrimination Associated With Views of Physical Activity and Climate Policy Support in Canada?

Background: Social climate refers to the general feelings, norms, and opinions in a society and may be affected by experiences of discrimination. This study examined whether experiences of discrimination are associated with the social climate of physical (in)activity and support for policies addressing dual benefits of physical activity (PA) and climate change.

Methods: Data from the 2023 Social Climate Survey were used (n = 1950; ≥18 y).

The relevance of the United Nations' Sustainable Development Goals in the promotion of sport, physical activity, and recreation in Canada.

Canada is unique in that it has established four national strategies in support of sport, physical activity, and/or recreation (SPAR). Though some of these strategies identify potential social and environmental correlates of SPAR, and articulate societal outcomes such as changes in behaviour and health, there are no explicit links to larger global initiatives such as the United Nations' Sustainable Development Goals (SDGs). Given that countries are expected to propose a plan for addressing the 17 SDGs, and that obvious overlap exists between several of the proposed development goals and SPAR, Canada should consider whether common indicators can be identified across these strategies and the SDGs simultaneously to facilitate more efficient and effective action.

Inequities in sleep duration and quality among adolescents in Canada.

Background: Several recent global events may have impacted adolescent sleep and exacerbated pre-existing disparities by social positions (i.e., social roles, identity or sociodemographic factors, and/or group memberships that are associated with power and oppression due to the structures and processes in a given society at given time).

"We are an active family": a randomized trial protocol to evaluate a family-system social identity intervention to promote child physical activity.

Background: Regular engagement in moderate-to-vigorous physical activity (MVPA) during childhood yields a myriad of health benefits, and contributes to sustained MVPA behaviors into adulthood. Given the influence of parents on shaping their child's MVPA behaviour, the family system represents a viable target for intervention. The purpose of this study is to compare the effects of two intervention conditions designed to increase child MVPA: (1) A standard education + planning intervention providing information about benefits, action planning, and coping planning; and (2) An augmented physical activity education + planning intervention that includes the components of the standard intervention, as well as a focus on family identity promotion and developing as an active member of the family.

Efficacy of a Physical Activity e-Learning Course Delivered to Early Childhood Educators on Preschoolers' Physical Activity and Sedentary Behaviors: A Cluster Randomized Controlled Trial.

Purpose: This study examined the effectiveness of an early childhood educator (ECE)-focused physical activity e-Learning course on children's physical activity and sedentary time in childcare.

Methods: A cluster randomized controlled trial was conducted in 12 childcare centers in London, Ontario, Canada. A total of 145 preschoolers and 42 ECEs participated in this study.

Development and validation of the Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) in 14 countries: study protocol.

Introduction: Global surveillance of physical activity (PA) of children and adolescents with questionnaires is limited by the use of instruments developed in high-income countries (HICs) lacking sociocultural adaptation, especially in low- and middle-income countries (LMICs); under-representation of some PA domains; and omission of active play, an important source of PA. Addressing these limitations would help improve international comparisons, and facilitate the cross-fertilisation of ideas to promote PA. We aim to develop and assess the reliability and validity of the app-based Global Adolescent and Child Physical Activity Questionnaire (GAC-PAQ) among 8-17 years old in 14 LMICs and HICs representing all continents; and generate the 'first available data' on active play in most participating countries.

The efficacy of the TEACH e-Learning course at improving early childhood educators' physical activity and sedentary behaviour self-efficacy, knowledge, intentions, and perceived behavioural control: a randomized controlled trial.

Background: Early childhood educators play a critical role in promoting physical activity and reducing sedentary time in childcare centres. However, early childhood educators receive limited specialised pre- and in-service learning opportunities relating to these behaviours and may lack the capacity to effectively engage children in healthy movement behaviours. This study aimed to examine the efficacy of an e-Learning course on increasing early childhood educators' physical activity and sedentary behaviour-related capacities.

The objective of this study was to investigate the association between children's parent-reported physical activity levels and weight changes during the COVID-19 pandemic among children and youth in Ontario Canada. A cross-sectional online survey was conducted in parents of children 5-17 years living in Ontario from May to July 2021. Parents recalled their child's physical activity and weight change during the year prior to their completion of the survey.

Assessing Support for Policy Actions With Co-Benefits for Climate Change and Physical Activity in Canada.

Background: Calls to action addressing the interconnections between physical (in)activity and the climate crisis are increasing. The current study aimed to investigate public support for policy actions that potentially have co-benefits for physical activity promotion and climate change mitigation.

Methods: In 2023, a survey through the Angus Reid Forum was completed by 2507 adults living in Canada.

Re-assessing the social climate of physical (in)activity in Canada.

Social-ecological models suggest that a strategy for increasing population physical activity participation is to reconstruct the "social climate" through changing social norms and beliefs about physical activity (PA). In this study, we assessed whether the PA social climate in Canada has changed over a five-year period after controlling for sociodemographic factors and PA levels. Replicating a survey administered in 2018, a sample of adults in Canada (n = 2,507) completed an online survey assessing social climate dimensions, including but not limited to descriptive and injunctive norms.

Prioritizing a research agenda on built environments and physical activity: a twin panel Delphi consensus process with researchers and knowledge users.

Association Between Children's and Parents' Physical Activity During the COVID-19 Pandemic: A Cross-Lagged Analysis.

Background: COVID-19 caused closures of movement supporting environments such as gyms and schools in Canada. This study evaluated the association between Ontario parents' and children's physical activity levels across time during COVID-19, controlling for variables that were identified as significant predictors of children's and parents' physical activity (e.g.

Public Health Surveillance of Behavioral Cancer Risk Factors During the COVID-19 Pandemic: Sentiment and Emotion Analysis of Twitter Data.

Background: The COVID-19 pandemic and its associated public health mitigation strategies have dramatically changed patterns of daily life activities worldwide, resulting in unintentional consequences on behavioral risk factors, including smoking, alcohol consumption, poor nutrition, and physical inactivity. The infodemic of social media data may provide novel opportunities for evaluating changes related to behavioral risk factors during the pandemic.

Objective: We explored the feasibility of conducting a sentiment and emotion analysis using Twitter data to evaluate behavioral cancer risk factors (physical inactivity, poor nutrition, alcohol consumption, and smoking) over time during the first year of the COVID-19 pandemic.

Promotion of physical activity among people who identify as women through the ParticipACTION mobile app.

Objective: Health and fitness mobile applications can increase users' physical activity (PA) levels (Lister et al., 2014). ParticipACTION is a national non-profit organization that developed a mobile app to target PA among adults (Truelove et al.

Child and youth physical activity throughout the COVID-19 pandemic: The changing role of the neighbourhood built and social environments.

We explored associations between neighbourhood environments and children and youths' moderate-to-vigorous physical activity (MVPA) during three different waves of the COVID-19 pandemic: spring 2020, fall 2020 and spring 2021, using three nationally representative cross-sectional surveys. In wave 2, higher dwelling density was associated with lower odds of a child achieving higher-level MVPA, however, the odds were higher in neighbourhoods with higher density that also had better access to parks. With regard to the social environment, ethnic concentration (wave 3) and greater deprivation (waves 1 and 3) were associated with lower odds of a child achieving higher-level MVPA.

Physical activity and recreational screen time change among adolescents in Canada: Examining the impact of COVID-19 in worsening inequity.

The purpose of this study was to assess if sub-populations of adolescents in Canada (i.e., race/ethnicity, sex/gender, and socioeconomic status [SES]) experienced a larger change in physical activity and screen time between the 2019-2020 (pre-pandemic) and the 2020-2021 (mid-pandemic) school years.
