Correlates of changes in children's independent mobility during the Covid-19 pandemic
Children's independent mobility (CIM) is linked to higher physical activity in cross-sectional research, but longitudinal assessments of correlates of changes in CIM are lacking. We investigated social-ecological correlates of changes in CIM during the COVID-19 pandemic and whether they differ by gender. Every six months between December 2020 and 2021, we surveyed Canadian parents of 7- to 12-year-olds ( n = 2291) to assess mobility licenses (chi…
Mixed‐methods systematic review exploring the associations underpinning active outdoor play with connection to nature and environmental stewardship
Active outdoor play has been positioned in the literature as an opportunity to address concerns over climate (in)action and the rising trend of disconnection from the outdoors and nature. The objective of this systematic review was to examine associations between active outdoor play and people's connection to nature and/or environmental stewardship across all ages. A systematic literature search of five bibliographic databases was conducted to id…

Child opinions related to a core outcome set for school-based healthy lifestyle behavior interventions
Introduction: Including children's perspectives developing health programs is a priority. This study gathered children's perspectives on outcomes in a Core Outcomes Set (COS), which they believe are important to measure in school-based healthy lifestyle behavioral interventions. Methods: Children aged 8-12 years from six countries across three continents participated in standardized interactive focus groups. An animation video was used to explain…
Association between physical activity, sleep, and screen time and cardiometabolic risk factors among Brazilian adolescents
A prominent gap in the literature is the lack of evidence from low-middle-income countries on the association between adherence to 24-Hour Movement Guidelines (physical activity, sleep, and screen time) and cardiometabolic risk factors among adolescents. This study examined the association between adherence to the 24-Hour Movement Guidelines and cardiometabolic risk factors among Brazilian adolescents. The probabilistic sample consisted of 29,226…
Stranger danger or good Samaritan? A cross-sectional study examining correlates of tolerance of risk in outdoor play among Canadian parents
Tailored interventions that reframe perceptions of risk for parents are needed. Such interventions could reframe concerns about stranger danger which persist despite occurrences of stranger abduction being extremely rare. Interventions could also be targeted to immigrant families and those with fewer children as they appear to be more averse to risk. A complementary focus on examining how cultural background influences risk perceptions is needed …

Method. Participating Latin American countries graded a set of common PA indicators following the harmonized methodology established by the Global Matrix…
Development of a 24-hour movement index
Background The Canadian 24-Hour Movement Guidelines for Children and Youth were introduced in 2016. They offer recommendations on moderate-to-vigorous physical activity, light physical activity, sedentary behaviour, and sleep in a typical 24-hour period to achieve optimal health outcomes. However, a lack of awareness and knowledge about the guidelines among children and parents is a concerning public health issue and may contribute to the low gui…

Introduction The ParticipACTION Report Card on Physical Activity for Children and Youth is the most comprehensive national assessment of physical activity and related behaviors, characteristics, and opportunities for children and youth. The 2022 Report Card assigned grades based on data gathered during the COVID-19 pandemic to reflect this extraordinary time-period in Canada. Further, while not graded, efforts were made to summarize key findings …
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 Ca…

Environmental Scan of Child and Youth Outdoor Play-Based Projects, Programs, Activities and Services Available in Canada During the Covid-19 Pandemic
Restrictions to childcare, schools, and after-school programs during COVID-19 have meant that many programs and organizations have adapted to take place outdoors. To better understand the nature and extent of these adaptations, we conducted a Canada-wide environmental scan of outdoor play-based child and youth projects, programs, activities, and services available during the height of the pandemic (2020-2021) using a "formal searching" method. We…
Parent-Perceived Changes in Active Transportation and Independent Mobility among Canadian Children in Relation to the Covid-19 Pandemic
Children's active transportation (AT) and independent mobility (IM) can provide benefits for health and social development. Using data from two national surveys, we assessed parent-perceived changes in AT and IM among 5- to 17-year-olds in Canada since the outbreak of COVID-19. About half of parents reported no changes, but two to three times more parents reported declines compared to increases in AT and IM. We explored many potential correlates …
Associations Between School Environments, Policies and Practices and Children's Physical Activity and Active Transportation
BACKGROUND: There is evidence of school-level variability in children's active behaviors. This study investigated the associations between school environments, policies and practices, and children's physical activity (PA) and active school transportation (AST), in a school ecology context. METHODS: We recruited children (N = 1699, age = 10.2 ± 1.0 years, 55.0% girls) in 37 schools from 3 diverse regions of Canada. We then collected data using que…

Physiological and health implications of a sedentary lifestyle
Sedentary behaviour is associated with deleterious health outcomes, which differ from those that can be attributed to a lack of moderate to vigorous physical activity. This has led to the field of “sedentary physiology”, which may be considered as separate and distinct from exercise physiology. This paper gives an overview of this emerging area of research and highlights the ways that it differs from traditional exercise physiology. Definitions o…

The purpose of this study was to determine the relationships among built and social environments and PA and overweight/obesity in 85 Ottawa neighbourhoods. Self-reported PA, height and weight were collected from 3,883 adults using the International PA Questionnaire from the 2003-2007 samples of the Rapid Risk Factor …
O1-5.5 Determinants of high folate concentration in the Canadian population
Introduction Canadians' red blood cell (RBC) folate has shifted towards high concentrations (>1360 nmol/l based on the 97th percentile of Americans post-fortification (NHANES)). Determinants of these high concentrations are poorly understood, though an association has been posited between high intakes of folic acid and adverse health outcomes. This research investigated determinants of high folate concentrations in Canadians. Methods RBC folate c…
P1-107 Contextual circumstances and patterns of childhood weight change
Introduction Worldwide, the prevalence of childhood obesity has not abated, indicating that prevention strategies, traditionally implemented at the individual- level, may not be effective. Conceptualising childhood obesity within multiple levels of influence, specifically within residential communities and over the lifecourse, is necessary to design effective prevention strategies that shift the distribution of risk downward. Methods Participants…
P1-117 Determinants of folate concentration in Canadian women of childbearing age
Objectives One-fifth of Canadian women of childbearing age have a red blood cell (RBC) folate below concentrations considered optimal for maximal neural tube defect risk reduction ( 3 times per day (82.9%)) and grain products ( 3 times per day (77.6%)). Detailed regression analysis results will be presented at the conference. Interpretation These results will inform nutrition policies, particularly those related to folic acid fortification of sel…

Systematic review of physical activity and health in the early years (aged 0–4 years)
The early years represent a critical period for promoting physical activity. However, the amount of physical activity needed for healthy growth and development is not clear. Using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework, we aimed to present the best available evidence to determine the relationship between physical activity and measures of adiposity, bone and skeletal health, motor skill development…
Local social environmental factors are associated with household food insecurity in a longitudinal study of children
These results highlight the potential role of the local social environment in preventing and ameliorating food insecurity at the household level. Stakeholders providing food security interventions at the community level should consider interactions with local social characteristics and perhaps changing the social environment itself. Further intervention research also examining interactions with household-level factors could lead to the developmen…
