Interventions to support healthy eating among populations are needed to address dietrelated chronic disease. Recreation and sport settings are increasingly identified as ideal settings for promoting overall health, particularly for children, through creation of environments that support positive health behaviours. These publicly funded settings typically support health through physical activity promotion. However, the food environment within them is often not reflective of nutrition guidelines. As more jurisdictions release nutrition guidelines in such settings, the purpose of this study was to assess whether voluntary nutrition guidelines, released in 2015 in the Canadian province of Nova Scotia, had any impact on food environments in these settings. Baseline and follow-up audits of food environments were conducted one year before (in 30 facilities) and one year after guideline release (in 27 facilities). Audits involved classifying all foods and beverages within vending machines and concessions as Do Not Sell, Minimum, Moderate, or Maximum nutrition, using criteria provided in the guidelines. The proportion of items within each category was calculated, and differences from pre- to post-guideline release were assessed using Chi-squared statistics. Results indicated limited change in food and beverage provision from pre- to post- guideline release. In fact, from pre- to post-guideline release, the proportion of Do Not Sell vending beverages and concession foods increased significantly, while Maximum concession beverages decreased, suggesting a worsening of the food environment post-guideline release. Findings suggest that voluntary guidelines alone are insufficient to improve food environments in recreation and sport settings. For widespread changes in the food environment of these settings to occur, more attention needs to be paid to reducing social, cultural, political and economic barriers to change (real and perceived) that have been identified in these settings, alongside developing leadership and capacity within facilities, to ensure that positive changes to food environments can be implemented and sustained.

Background Healthcare providers are a primary source of information on preventive health issues for patients. Further research related to physical activity (PA) promotion in the primary care setting is needed. Objective To explore the feasibility of a physician and community PA intervention using a pedometer for: increasing PA levels among inactive patients; enhancing relationships between physicians and community PA partners; and influencing the PA promotion habits of physicians. Methods A 6-week PA intervention was delivered to 152 inactive patients who were recruited in physician waiting rooms, counselled by their physicians, provided with a pedometer and referred to a community action site (CAS) at their local recreation centre for further support. PA was measured at baseline and follow-up using the International Physical Activity Questionnaire. Follow-up interviews were conducted with physicians and recreation representatives on the challenges and benefits associated with the intervention. Results Study patients significantly increased their PA (103% change in MET min/week). Physicians and recreation professionals were highly satisfied with the intervention and partnership. There were challenges to ongoing communication. Physicians reported increased awareness of the pedometer and community resources as supports for PA. Conclusion A pedometer-based PA intervention delivered by physicians in partnership with a community PA stakeholder is feasible and warrants further research. Long-term maintenance of this intervention would require resources for pedometers, and ongoing contact and communication between the physicians and CAS to ensure availability of community supports.

Purpose To describe physical activity (PA) intensity across a school day and assess the percentage of girls and boys achieving recommended guidelines. Methods The authors measured PA via accelerometry in 380 children (8-11 years) and examined data representing (1) the whole school day, (2) regular class time, (3) recess, (4) lunch and (5) scheduled physical education (PE). Activity was categorised as sedentary (SED), light physical activity (LPA) or moderate to vigorous physical activity (MVPA) using age-specific thresholds. They examined sex differences across PA intensities during each time period and compliance with recommended guidelines. Results Girls accumulated less MVPA and more SED than boys throughout the school day (MVPA -10.6 min; SED +13.9 min) recess (MVPA -1.6 min; SED +1.7 min) and lunch (MVPA -3.1 min; SED +2.9 min). Girls accumulated less MVPA (-6.2 min), less LPA (-2.5 min) and more SED (+9.4 min) than boys during regular class time. Fewer girls than boys achieved PA guidelines during school (90.9% vs 96.2%), recess (15.7% vs 34.1%) and lunch (16.7% vs 37.4%). During PE, only 1.8% of girls and 2.9% of boys achieved the PA guidelines. Girls and boys accumulated similar amounts of MVPA, LPA and SED. Conclusion The MVPA deficit in girls was due to their sedentary behaviour as opposed to LPA. Physical activity strategies that target girls are essential to overcome this deficit. Only a very small percentage of children met physical activity guidelines during PE. There is a great need for additional training and emphasis on PA during PE. In addition schools should complement PE with PA models that increase PA opportunities across the school day. [ABSTRACT FROM AUTHOR]

Background: Early childhood education and care (ECEC) settings are key for improving health behaviors, including physical activity (PA) and nutrition. In 2017, the province of British Columbia (BC) implemented a provincial-level Active Play policy supported by a capacity-building intervention. Significant improvements in all PA policies and practices and the majority of nutrition policies were observed post-implementation. The purpose of this study was to understand if PA and nutrition policies and practices were maintained at 5+ years post-provincial policy implementation. Methods: This study employed a repeated cross-sectional design to distribute surveys querying about PA and nutrition policies and practices to ECEC centers across BC at three time points: time 1, prior to implementation of the Active Play standard (2016-2017) and capacity-building intervention, time 2, 1-2 years post-implementation (2018-2019), and time 3, 5+ years post-implementation (2022-2023). Results: The majority of PA and all nutrition policies were maintained from time 2 ( n = 378) to time 3 ( n = 639). Prevalence of policies related to the provision of activities that address fundamental movement skills (odds ratio [OR] = 0.30) and total amount of active play (OR = 0.56) significantly decreased from time 2 to time 3. All reported PA practice prevalence levels decreased to time 1 levels. Conclusions: Center-level health behavior policies were largely maintained 5 years post-implementation, except some PA policies and practices returned to pre-implementation levels. Staff capacity and turnover as well as change in implementation support may explain these changes. Ongoing implementation support is needed to ensure maintenance of health promoting policies and practices in ECEC.

Objective: The purpose of this study was to examine the dissemination of the healthy eating component of Appetite to Play at scale using the Reach, Effectiveness, Adoption, Implementation, Maintenance (RE-AIM) framework., Design: The Appetite to Play capacity-building intervention is a set of evidence-informed implementation strategies aimed at enhancing the adoption of recommended practices for promoting healthy eating and active play in early years settings. The evaluation was pragmatic, employing both quantitative (surveys) and qualitative (interviews) data collection., Setting: The Appetite to Play intervention was delivered through in-person community-based workshops, virtual workshops, asynchronous e-learning and online resources., Participants: We received completed surveys from 1670 in-person workshop participants (96 % female), and twenty-three (all female) survey respondents also participated in a telephone interview. Approximately two-thirds of all participant groups were certified early childhood educators., Results: Results indicated that Appetite to Play had high reach (25 867 individual website visits, 195 workshops delivered), effectiveness (significant increases in care provider's knowledge, confidence ( P < 0·05) and high post-intervention intention to implement), adoption (11 % of educators in BC trained) and implementation (good alignment with implementation strategies and current practices), with a significant maintenance plan to support the intervention's future success., Conclusions: An evidence-based capacity-building intervention with an emphasis on training and provision of practical online resources can improve early years providers' knowledge, confidence and intention to implement recommended practices that promote healthy eating. Further research is needed to determine the impact on child-level outcomes and how parents can be supported in contributing to positive food environments.

Emerging evidence suggests that the accuracy of a child's perceived physical competence (PPC) impacts participation in physical activity. We examined differences in active physical recreation (APR) participation based on clusters of high and low motor competence and perceptions from grades 3-5. Participants were a longitudinal sample ( n = 155; 85 girls) of grade three, four, and five children. Fundamental motor skills (FMSs) were assessed using the TGMD-2, perceptions were assessed using the Self-Perception Profile for Children, and APR was measured using the Children's Assessment of Participation and Enjoyment. K-means cluster analysis was used to create four clusters per grade based on participants' FMSs and PPC z -scores. Differences in FMSs, PPC, and APR with cluster group as a factor were examined using a series of factorial ANOVAs. In each grade, participants in the high-high cluster participated in significantly more APR than those in the low-low cluster ( p = 0.002 in grades three and four; p < 0.001 in grade five). Among the less accurate clusters (e.g., low FMSs with high PPC) was a trend toward positive FMSs growth among the children with higher perceptions. Results show that combinations of FMSs and PPC influence patterns of engagement or disengagement in active physical recreation persistently across middle childhood.

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. In Phase 1, we invited academic experts to participate in a Delphi study to rate, provide recommendations, and achieve consensus on questionnaire items that were based on the Capability, Opportunity, and Motivation Behavior (COM-B) model. Each item was ranked on the degree to which it matched the content of the COM-B model, using a 5-point scale ranging from '1 = Poor match' to '5 = Excellent match'. In Phase 2, we interviewed primary and secondary school teachers using a 'think-aloud' approach to assess their understanding of the items. In Phase 3, teachers (n = 196) completed the COM-PASS to assess structural validity using confirmatory factor analysis (CFA)., Results: Thirty-eight academic experts from 14 countries completed three rounds of the Delphi study. In the first round, items had an average rating score of 4.04, in the second round 4.51, and in the third (final) round 4.78. The final tool included 14 items, which related to the six constructs of the COM-B model: physical capability, psychological capability, physical opportunity, social opportunity, reflective motivation, and automatic motivation. In Phase 2, ten teachers shared their interpretation of COM-PASS via a 20-min interview, which resulted in minor changes. In Phase 3, CFA of the 3-factor model (i.e., capability, opportunity, and motivation) revealed an adequate fit to the data (χ 2  = 122.6, p < .001, CFI = .945, TLI = .924, RMSEA = .066). The internal consistencies of the three subscale scores were acceptable (i.e., capability: α = .75, opportunity: α = .75, motivation: α = .81)., Conclusion: COM-PASS is a valid and reliable tool for assessing teachers' capability, opportunity, and motivation to deliver physical activity interventions in schools. Further studies examining additional psychometric properties of the COM-PASS are warranted., (© 2024. The Author(s).)

Background: Given the significance of motor competence (MC) for healthy development and as a cornerstone for lifelong physical activity (PA), it is crucial to understand the manifold factors that are associated with MC. Thus, the aim of the present study was to investigate correlates of children's MC and their fundamental movement skills (FMS) within their daily life from a comprehensive biopsychosocial-ecological perspective., Methods: This is a cross-sectional sub-study of the 'Physical Literacy for Communities (PL4C)' WAVES cohort study conducted in the West Vancouver School District, Canada. Motor competence was assessed using the PLAYfun tool including overall MC score and five FMS category scores, namely, running, locomotor skills, upper and lower body control and balance skills. By means of structural equation modeling (SEM), direct associationswith MC and with the specific FMS categories addressing physical activity behavior, self-perceived physical literacy, parenting, and school ground design were investigated., Results: A total of 355 children with a mean age of 7.5 years and 111.1 min of MVPA per day participated. The group comprised 51% boys and 47% girls from 14 elementary schools. Most children were at an emerging MC-level (71%), while those at a competent MC-level exhibited significantly more daily minutes of MVPA (123 versus 109, p = 0.001). Additionally, they played outdoors more frequently and engaged in more instructor-led PA. The results revealed that logistical support from parents had not only a direct positive association with overall MC, both for girls and boys, but also with most of the FMS categories. However, the correlates of MC varied between genders and showed different patterns across the five FMS categories. While time spent in sports or coach-/instructor-led physical activities had a significant SEM generated direct effect only for boys' MC and for locomotor, upper body object control and balance, the aesthetic design of the school grounds was only associated with girls' MC and those same three FMS categories. Multivariate SEM could explain 26% of variance for girls' MC and 30% for boys'., Conclusions: This exploratory baseline assessment revealed parental logistical support as an important correlate of MC, irrespective of gender. There were distinct gender patterns across biopsychosocial-ecological correlates influencing MC and FMS. Despite the heterogeneity of the results, our findings indicate a potential role of school ground design in supporting the development of children's MC, especially for girls., (© 2024.

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., Methods: A two-group parallel randomized controlled trial was conducted with early childhood educators in Canada (M age = 41.78, 97% female). Participants randomized to the intervention group were asked to complete a physical activity and sedentary behaviour e-Learning course within a 4-week period. Participants randomized to the waitlist control condition were assigned to a waitlist to receive the intervention after the testing period. Participants reported on their self-efficacy, knowledge, intentions, and perceived behavioural control relating to physical activity and sedentary behaviours at baseline, post-intervention, and 3 months follow-up. Linear mixed effects models were estimated to determine difference in changes in outcomes from baseline to post-intervention, and follow-up., Results: A total of 209 early childhood educators participated in the study (intervention n = 98; control n = 111). The TEACH e-Learning course was found to be efficacious at improving all of the examined outcomes, with standardized effect sizes ranging from d = 0.58 to d = 0.65 for self-efficacy outcomes, d = 0.66 to d = 1.20 for knowledge outcomes, d = 0.50 to d = 0.65 for intention outcomes, and d = 0.33 to d = 0.69 for perceived behavioural control outcomes post-intervention. The intervention effects were sustained at follow-up for all outcomes apart from perceived behavioural control to limit screen time. Additionally, the magnitude of the effect for knowledge outcomes decreased at follow-up, with standardized effect sizes ranging from d = 0.49 to d = 0.67., Conclusions: The e-Learning course was highly successful at improving early childhood educators' capacity pertaining to physical activity and sedentary behaviours. Providing training content through e-Learning may be an efficacious approach to providing continual professional learning opportunities relating to physical activity and sedentary time to early childhood educators on a large scale., (© 2024.

Over the last 4 decades, physical activity researchers have invested heavily in determining "what works" to promote healthy behaviors in schools. Single and multicomponent school-based interventions that target physical education, active transportation, and/or classroom activity breaks effectively increased physical activity among children and youth. Yet, few of these interventions are ever scaled-up and implemented under real-world conditions and in diverse populations. To achieve population-level health benefits, there is a need to design school-based health-promoting interventions for scalability and to consider key aspects of the scale-up process. In this opinion piece, we aim to identify challenges and advance knowledge and action toward scaling-up school-based physical activity interventions. We highlight the key roles of planning for scale-up at the outset, scale-up pathways, trust among partners and program support, program adaptation, evaluation of scale-up, and barriers and facilitators to scaling-up. We draw upon our experience scaling-up effective school-based interventions and provide a solid foundation from which others can work toward bridging the implementation-to-scale-up gap.

Background: Governments internationally have invested hugely in the implementation and scale-up of school-based physical activity interventions, but have little evidence of how to best sustain these interventions once active implementation support ceases. This study will assess the effectiveness of a multi-strategy sustainability intervention on classroom teachers' sustainment of energisers (short 3-5 min physical activity breaks during class-time) scheduled across the school day from baseline to 12 and 24-month follow-up., Methods: A cluster randomised controlled trial will be conducted in 50 primary schools within the Hunter New England, Illawarra Shoalhaven, Murrumbidgee and Northern New South Wales (NSW) Local Health Districts of NSW Australia. Schools will be randomly allocated to receive either usual support or the multi-strategy sustainability intervention that includes: centralised technical assistance from a trained project officer; formal commitment and mandated change obtained from school principals; training in-school champions; reminders for teachers; educational materials provided to teachers; capturing and sharing local knowledge; and engagement of parents, carers and the wider school community. The primary trial outcome will be measured via a teacher logbook to determine the between-group difference in the change in mean minutes of energisers scheduled across the school day at 12 and 24-month follow-up compared to baseline. Analyses will be performed using an intention to treat framework. Linear mixed models will be used to assess intervention effects on the primary outcome at both follow-up periods., Discussion: This study will be one of the first randomised controlled trials to examine the impact of a multi-strategy sustainability intervention to support schools' sustainment of a physical activity intervention. The proposed research will generate new evidence needed for the partnering organisations to protect their considerable investments to date in physical activity promotion in this setting and will provide seminal evidence for the field globally., Trial Registration: ACTRN12620000372987 version 1 registered 17 th March 2020.

Background: Physically Active Children in Education (PACE) is an effective implementation intervention for increasing the number of minutes classroom teachers schedule physical activity each week. To date, evaluations of PACE have included a smaller number of schools from only one region in New South Wales Australia. If PACE is to have population-wide benefits we must be able to deliver this support to a larger number of schools across multiple regions. This study aimed to evaluate the scale-up of PACE., Methods: An uncontrolled before and after study, with 100 schools from three regions was conducted. Participating schools received PACE for approximately 12 months. We assessed the following outcomes: delivery of the evidence-based intervention (EBI) (i.e. minutes of physical activity scheduled by classroom teachers per week); delivery of the implementation strategies (i.e. reach, dose delivered, adherence and indicators of sustainability); and key determinants of implementation (i.e. acceptability of strategies and cost). Data were collected via project officer records, and principal and teacher surveys. Linear mixed models were used to assess EBI delivery by evaluating the difference in the mean minutes teachers scheduled physical activity per week from baseline to follow-up. Descriptive data were used to assess delivery of the implementation strategies and their perceived acceptability (i.e. PACE). A prospective, trial-based economic evaluation was used to assess cost., Results: Delivery of the EBI was successful: teachers increas their average minutes of total physical activity scheduled across the school week by 26.8 min (95% CI: 21.2, 32.4, p < 0.001) after receiving PACE. Indicators for delivery of implementation strategies were high: 90% of consenting schools received all strategies and components (reach); 100% of strategies were delivered by the provider (dose); >50% of schools adhered to the majority of strategies (11 of the 14 components); and acceptability was > 50% agreement for all strategies. The incremental cost per additional minute of physical activity scheduled per week was $27 per school (Uncertainty Interval $24, $31)., Conclusions: PACE can be successfully delivered across multiple regions and to a large number of schools. Given the ongoing and scalable benefits of PACE, it is important that we continue to extend and improve this program while considering ways to reduce the associated cost., (© 2023.

Background: In 2016-17, the government of British Columbia (BC) enacted a mandatory policy outlining Active Play Standards (AP Standards) alongside a capacity building initiative (Appetite to Play) focused on implementing policies and practices to support physical activity in childcare centres. We aimed to identify factors at the provider and organizational levels as well as attributes of the Standards hypothesized to influence implementation (i.e., changes in policies and practices)., Methods: We conducted surveys before (2016-2017) and after (2018-2019) enforcement of the AP Standards among 146 group childcare centres across BC. The 2018-19 surveys measured theoretically based constructs associated with implementation of policies and practices (9 childcare- and 8 provider- level characteristics as well as 4 attributes of the licensing standards). Characteristics that were associated in simple regression models were entered in multivariable regression models to identify factors associated with policy and practice changes related to fundamental movement skills (FMS), screen time, total amount of active play (AP) and total amount of outdoor AP from baseline to follow-up., Results: In multivariable analyses, higher staff capacity (OR = 2.1, 95% 1.2, 3.7) and perceived flexibility of the standards (OR: 3.3, 95% 1.5, 7.1) were associated with higher odds of a policy change related to FMS. Higher staff commitment to the AP standards was associated with a higher odds of policy changes related to screen time (OR = 1.6, 95% CI: 1.1, 2.4) and amount of AP (OR: 1.5, 95% 1.0, 2.3). Higher institutionalization of PA policies was associated with a higher odds of policy changes related to the amount of AP (OR: 5.4, 95% CI: 1.5, 20). Higher self-efficacy was associated with a higher odds of policy changes related to outdoor AP (OR = 2.9, 95% 1.1, 7.8). Appetite to Play training was a positively associated with practice changes related to FMS (β = 0.5, 95% CI: 0.1, 0.9)., Conclusions: A hierarchy of theoretically defined factors influenced childcare providers' implementation of the AP Standards in BC. Future research should test the feasibility of modifying these factors to improve the implementation of PA policy and practice interventions in this setting., (© 2023.

Background: Physical literacy (PL) is considered an important determinant of children's physical activity through which health benefits may be derived. The purpose of this study is to describe a sample of Canadian children's baseline levels of PL and movement behaviors, and explore whether the associations between PL and their mental wellbeing, if any, are mediated by moderate-to-vigorous physical activity (MVPA)., Methods: All grade two children in 14 elementary schools in the West Vancouver School District, Canada were invited to participate in a two-year longitudinal project. PL was assessed through PLAYfun and PLAYself tools. Physical activity was measured by wrist-worn accelerometers (GT3X + BT) for seven days. Children's mental well-being was assessed using the Strengths and Difficulties Questionnaire (SDQ). A score of total difficulties was aggregated for internalizing and externalizing problems., Results: A total of 355 children aged 7-9 (183 boys, 166 girls, 6 non-binary) participated with 258 children providing valid accelerometer data. Children exhibited an average of 111.1 min of MVPA per day, with 97.3% meeting the physical activity guidelines. Approximately 43% (108/250) of participants were meeting the Canadian 24-h movement guidelines. Children were at an 'emerging' level of overall physical competence (45.8 ± 5.6) and reported a mean score of 68.9 (SD = 12.3) for self-perceived PL, with no significant differences between boys and girls. PL was significantly associated with MVPA (r = .27) and all SDQ variables (rs = -.26-.13) except for externalizing problems. Mediation analyses showed PL was negatively associated with internalizing problems and total difficulties when the association with MVPA was considered. However, the mediating role of MVPA was found only between PL and internalizing problems, β = -.06, 95%CI [-.12, -.01]., Conclusions: Although most of our sample was physically active and showed higher adherence to 24-H movement guidelines than comparable population data, the motor competence and self-perceived PL of our sample were similar to those of previous studies. PL has an independent association with children's internalizing problems and total difficulties. Ongoing assessment will investigate the relationships between PL and children's mental health from a longitudinal perspective., (© 2023. The Author(s).)

With an increasing number of children attending regular early childhood education and care (ECEC), this setting presents an opportunity to develop physical activity habits and movement skills of children. These behaviours play an important role in the development and well-being of children. In 2017, an Active Play Standard was introduced in British Columbia, Canada, to mandate practices related to physical activity, screen time and movement skill development in licensed ECEC. A capacity-building initiative including training and online resources was released alongside these guidelines to support implementation. The purpose of this study was to qualitatively examine the barriers and facilitators ECEC practitioners faced in implementing the standard, and to explore the role of the capacity-building initiative. Data were collected via semi-structured telephone interviews with educators (n = 23). Data were coded using thematic analysis and sorted into three major themes influencing provision of physical activity opportunities: attributes and impact of the Active Play standard and capacity-building workshop, characteristics of providers and characteristics of ECEC settings. Future studies should consider targeting factors including organizational culture and climate, and provider capacity to provide physical activity and fundamental movement skill programming, and support for facility level policies and collaborative planning processes that create a positive physical activity culture., (© The Author(s) 2022.

The PLAYshop program is a parent-focused physical literacy intervention for early childhood. This single-group mixed-methods pilot study aimed to explore the feasibility of virtually delivering and assessing the PLAYshop program. The virtual PLAYshop program included a virtual workshop, resources/basic equipment, and two booster emails (3-week and 6-week follow-up). Data on 34 preschool-aged children (3-5 years) and their parents from Edmonton and Victoria, Canada, were collected via an online questionnaire, virtual assessment session, and interview at single or multiple time points (baseline, post-workshop, 2-month follow-up). Intraclass correlation coefficients (ICCs), paired t -tests, repeated measures ANOVAs, and thematic analyses were conducted. Regarding feasibility, most parents (≥94%) were satisfied/extremely satisfied with the virtual workshop and planned to continue physical literacy activities post-workshop. The virtual assessment protocol for children's fundamental movement skills (FMS; overhand throw, underhand throw, horizontal jump, hop, one-leg balance) was feasible, with high completion rates (>90%) and reliable scoring (ICC = 0.79-0.99). For positive changes in potential outcomes, a medium effect size was observed for children's hopping skills ( d = 0.54), and large effect sizes were observed for several parental outcomes (partial η 2 = 0.20-0.54). The findings support the feasibility and potential positive outcomes of the virtual PLAYshop program. A larger randomized controlled efficacy trial is recommended.

Purpose: The purpose of this research was to develop, implement, and test the efficacy of a theory-driven, evidence-informed peer leadership program for elementary school students (Grade 6 and 7; age 11-12 years) and the Grade 3/4 students with whom they were partnered. The primary outcome was teacher ratings of their Grade 6/7 students' transformational leadership behaviors. Secondary outcomes included: Grade 6/7 students' leadership self-efficacy, as well as Grade 3/4 motivation, perceived competence, general self-concept, fundamental movement skills, school-day physical activity, and program adherence, and program evaluation., Methods: We conducted a two-arm cluster randomized controlled trial. In 2019, 6 schools comprising 7 teachers, 132 leaders, and 227 grade 3 and 4 students were randomly allocated to the intervention or waitlist control conditions. Intervention teachers took part in a half-day workshop (January 2019), delivered 7 x 40 minute lessons to Grade 6/7 peer leaders (February and March 2019), and these peer leaders subsequently ran a ten-week physical literacy development program for Grade 3/4 students (2x30 minutes sessions per week). Waitlist-control students followed their usual routines. Assessments were conducted at baseline (January 2019) and immediately post-intervention (June 2019)., Results: The intervention had no significant effect on teacher ratings of their students' transformational leadership (b = 0.201, p = .272) after controlling for baseline and gender. There was no significant condition effect for Grade 6/7 student rated transformation leadership (b = 0.077, p = .569) or leadership self-efficacy (b = 3.747, p = .186) while controlling for baseline and gender. There were null findings for all outcomes related to Grade 3 and 4 students., Discussion: Adaptions to the delivery mechanism were not effective in increasing leadership skills of older students or components of physical literacy in younger Grade 3/4 students. However, teacher self-reported adherence to the intervention delivery was high., Trial Registration: This trial was registered on December 19th, 2018 with Clinicaltrials.gov (NCT03783767), https://clinicaltrials.gov/ct2/show/NCT03783767., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2023 Hulteen et al.

Introduction: The PLAYshop programme is a novel, brief, theory-based, parent-focused physical literacy intervention in early childhood designed to address the major public health issue of childhood physical inactivity. The primary objective of this study is to examine the efficacy of the virtually delivered PLAYshop programme in increasing preschool-aged children's physical literacy, including fundamental movement skills and motivation and enjoyment., Methods and Analysis: This study aims to recruit 130 families with preschool-aged children (3-5 years) from Alberta and British Columbia, Canada who will be randomised to an intervention or control group. The PLAYshop programme is informed by the Capability, Opportunity, Motivation, Behavior (COM-B) model and includes four intervention strategies: (1) educational training via a 60 min virtual synchronous workshop, (2) educational resources via handouts, (3) material resources via a goody bag of basic active play equipment and (4) follow-up support via access to a digital app with an online toolkit and four biweekly booster lessons (1-week, 3-week, 5-week and 7-week follow-up). To assess the primary outcome of physical literacy, five fundamental movement skills (overhand throw, underhand throw, horizontal jump, hop, one leg balance) will be measured virtually at baseline and 2-month follow-up using the Test of Gross Motor Development (TGMD) and the Movement Assessment Battery for Children-Second Edition (MABC-2) tools. Additionally, children's motivation and enjoyment will also be assessed at baseline and 2-month follow-up by: (1) parental-report using items from the Preschool Physical Literacy Assessment (PrePLAy) and (2) self-report using an adapted Five Degrees of Happiness Likert scale for children. The control group will receive the PLAYshop programme after the 2-month follow-up., Ethics and Dissemination: The protocol was approved by the University of Alberta (00093764) and University of Victoria (16-444) Research Ethics Boards. Findings will be disseminated through peer-reviewed publications, conference presentations, social and traditional media and a circulated infographic., Trial Registration Number: NCT05255250., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2022.

Purpose: Physical activity (PA), sedentary time (SED), and energy intake (EI) are associated with fat mass accrual in children and youth. Previous studies relied primarily on cross-sectional designs and proxy measures of body composition such as body mass index. We aimed to prospectively investigate associations between PA, SED, EI, and total body fat mass accrual using dual-energy x-ray absorptiometry., Methods: This analysis of the mixed longitudinal Healthy Bones III Study included data from 312 participants (138 boys age 9 to 21 yr at baseline). For each participant, we acquired a maximum of four annual total body dual-energy x-ray absorptiometry scans from which we determined fat mass (in kilograms; n = 748 observations). We assessed total PA, moderate-to-vigorous PA (MVPA) and SED with accelerometers (ActiGraph GT1M) and measured EI via 24-h dietary recall. We fit sex-specific multilevel models adjusting for maturity (years from age at peak height velocity (APHV)), weight status, ethnicity, total PA, MVPA, SED, and EI., Results: Boys and girls demonstrated divergent trajectories of fat mass accrual; rate of fat mass accrual in girls was four times greater than boys at APHV and increased across adolescence, whereas boys' fat mass plateaued after APHV. In boys, within-person change in MVPA negatively predicted fat mass independent of SED; each annual increase in MVPA of 6 min·d -1 was associated with a 0.21-kg lower fat mass. In girls, between-person average MVPA negatively predicted fat mass accrual independent of SED; greater MVPA of 4 min·d -1 across adolescence was associated with a 0.31-kg lower fat mass., Conclusions: MVPA demonstrates an independent and negative effect on fat mass in boys and girls. Given different trajectories of fat mass accrual and movement behaviors between boys and girls, PA interventions aimed at preventing obesity in youth may benefit from a sex and gendered approach., (Copyright © 2022 by the American College of Sports Medicine.)

Background: Generation Health (GH) is a 10-week family-based lifestyle program designed to promote a healthy lifestyle for families with children who are off the healthy weight trajectory in British Columbia, Canada. GH uses a blended delivery format that involves 10 weekly in-person sessions, and self-guided lessons and activities on a web portal. The blended program was adapted to be delivered virtually due to the COVID-19 pandemic. Currently, the effectiveness of the virtual GH program compared with that of the blended GH program remains unclear., Objective: We aimed to (1) compare the effectiveness of the virtual GH program delivered during the COVID-19 pandemic with that of the blended GH program delivered prior to the pandemic for changing child physical activity, sedentary and dietary behaviors, screen time, and parental support-related behaviors for child physical activity and healthy eating, and (2) explore virtual GH program engagement and satisfaction., Methods: This study used a single-arm pre-post design. The blended GH program (n=102) was delivered from January 2019 to February 2020, and the virtual GH program (n=90) was delivered during the COVID-19 pandemic from April 2020 to March 2021. Families with children aged 8-12 years and considered overweight or obese (BMI ≥85th percentile according to age and sex) were recruited. Participants completed preintervention and postintervention questionnaires to assess the children's physical activity, dietary and sedentary behaviors, and screen time, and the parent's support behaviors. Intervention feedback was obtained by interviews. Repeated measures ANOVA was used to evaluate the difference between the virtual and blended GH programs over time. Qualitative interviews were analyzed using thematic analyses., Results: Both the virtual and blended GH programs improved children's moderate-to-vigorous physical activity (F 1,380 =18.37; P<.001; ηp 2 =0.07) and reduced screen time (F 1,380 =9.17; P=.003; ηp 2 =0.06). However, vegetable intake was significantly greater in the virtual GH group than in the blended GH group at the 10-week follow-up (F 1,380 =15.19; P<.001; ηp 2 =0.004). Parents in both groups showed significant improvements in support behaviors for children's physical activity (F 1,380 =5.55; P=.02; ηp 2 =0.002) and healthy eating (F 1,380 =3.91; P<.001; ηp 2 =0.01), as well as self-regulation of parental support for children's physical activity (F 1,380 =49.20; P<.001; ηp 2 =0.16) and healthy eating (F 1,380 =91.13; P<.001; ηp 2 =0.28). Families in both groups were satisfied with program delivery. There were no significant differences in attendance for the weekly in-person or group video chat sessions; however, portal usage was significantly greater in the virtual GH group (mean 50, SD 55.82 minutes) than in the blended GH group (mean 17, SD 15.3 minutes; P<.001)., Conclusions: The study findings suggested that the virtual GH program was as effective as the blended program for improving child lifestyle behaviors and parental support-related behaviors. The virtual program has the potential to improve the flexibility and scalability of family-based childhood obesity management interventions., (©Kayla Nuss, Rebecca Coulter, Bianca DeSilva, Jeann Buenafe, Ronak Sheikhi, Patti-Jean Naylor, Sam Liu.

Background: To maximise their potential health benefits, school-based physical activity policies need to be implemented at scale. This paper describes the third in a sequence of trials that sought to optimise an effective strategy (PACE) to assist schools' implementation of a physical activity policy. Specifically, it aimed to determine the probability that a multi-strategy intervention adapted to reduce in-person contact (Adapted PACE) was "as good as" the original intervention (PACE) in increasing the weekly minutes of structured physical activity implemented by classroom teachers., Methods: A noninferiority cluster randomised controlled trial was undertaken with 48 primary schools in New South Wales, Australia. Schools were randomised to receive PACE or a model with adaptations made to the delivery modes (Adapted PACE). Teachers' scheduled minutes of weekly physical activity was assessed at baseline (Oct 2018-Feb 2019) and 12-month follow-up (Oct-Dec 2019). The noninferiority margin was set at - 16.4 minutes based on previous data and decision panel consensus. A linear mixed model analysed within a Bayesian framework was used to explore noninferiority between the two PACE models. A cost minimisation analysis was conducted from the health service provider perspective, using the Australian dollar (AUD)., Results: The posterior estimate for the between group difference at follow-up was - 2.3 minutes (95% credible interval = - 18.02, 14.45 minutes). There was an estimated 96% probability of Adapted PACE being considered noninferior (only 4% of the posterior samples crossed the noninferiority margin of - 16.4 minutes). That is, the minutes of physical activity implemented by teachers at Adapted PACE schools was not meaningfully less than the minutes of physical activity implemented by teachers at PACE schools. The mean total cost was AUD$25,375 (95% uncertainty interval = $21,499, $29,106) for PACE and AUD$16,421 (95% uncertainty interval = $13,974, $19,656) for Adapted PACE; an estimated reduction of AUD$373 (95% uncertainty interval = $173, $560) per school., Conclusions: It is highly probable that Adapted PACE is noninferior to the original model. It is a cost-efficient alternative also likely to be a more suitable approach to supporting large scale implementation of school physical activity policies., Trial Registration: Retrospectively registered with the Australian New Zealand Clinical Trials Registry (ACTRN12619001229167)., (© 2022.

Background: The Early Intervention Program (EIP) was a 10-week, blended, in-person and online lifestyle intervention for families with children who were off the healthy weight trajectory. The engagement pattern and the dose response of EIP have not been examined., Objective: The aims of this paper are to examine families' engagement patterns with the EIP and to evaluate the dose-response relationship between EIP engagement patterns and physical activity and healthy eating-related outcomes at 10 weeks., Methods: Families with children (8-12 years old) who are off the healthy weight trajectory (child BMI ≥85th percentile for age and sex) were recruited. Pre- and postintervention questionnaires assessed child lifestyle behaviors, parental support behaviors, family lifestyle habits, as well as parental physical activity and healthy-eating identity. Hierarchical cluster analysis of both in-person and online components was used to classify engagement patterns. Regression analysis assessed differences in outcomes by engagement groups., Results: Two distinct clusters of engagement groups were identified (N=66), which were in-person (IP; n=40, 61%) and in-person + online (IP+; n=26, 39%) engagement. Relative to the IP group at week 10, IP+ showed a greater child moderate-to-vigorous physical activity level (1.53, SD 0.56; P=.008), child physical activity confidence (1.04, SD 0.37; P=.007), parental support for child physical activity (5.54, SD 2.57; P=.04) and healthy eating (2.43, SD 1.16; P=.04), family habits for physical activity (3.02, SD 1.50; P=.049) and healthy eating (3.95, SD 1.84; P=.04), and parental identity for physical activity (2.82, SD 1.19; P=.02)., Conclusions: The online EIP portal complemented the in-person sessions. Additional engagement with the portal was associated with greater improvements in child physical activity and parental support behaviors, habits, and identity for physical activity., (©Sam Liu, Nicholas Smith, Kayla Nuss, Megan Perdew, Dimas Adiputranto, Patti-Jean Naylor.

Background: Physically Active Children in Education (PACE) is composed of eight implementation strategies that improves schools' implementation of a government physical activity policy. A greater understanding of each discrete implementation strategy could inform improvements to PACE for delivery at-scale. This study aimed to: (A) measure the dose delivered, fidelity, adoption and acceptability of each strategy using quantitative data; (B) identify implementation barriers and facilitators using qualitative data; and (C) explore the importance of each strategy by integrating both data sets (mixed methods)., Methods: This study used data from a cluster randomised noninferiority trial comparing PACE with an adapted version (Adapted PACE) that was delivered with reduced in-person external support to reduce costs and increase scalability. Data were collected from both trials arms for between-group comparison. Descriptive statistics were produced using surveys of principals, in-school champions and teachers; and project records maintained by PACE project officers (objective A). Thematic analysis was performed using in-school champion and project officer interviews (objective B). Both data sets were integrated via a triangulation protocol and findings synthesized in the form of meta-inferences (objective C)., Results: Eleven in-school champions and six project officers completed interviews; 33 principals, 51 in-school champions and 260 teachers completed surveys. Regardless of group allocation, implementation indicators were high for at least one component of each strategy: dose delivered =100%, fidelity ≥95%, adoption ≥83%, acceptability ≥50%; and several implementation barriers and facilitators were identified within three broad categories: external policy landscape, inner organizational structure/context of schools, and intervention characteristics and processes. All strategies were considered important as use varied by school, however support from a school executive and in-school champions' interest were suggested as especially important for optimal implementation., Conclusion: This study highlights the importance of both executive support and in-school champions for successful implementation of school physical activity policies. In particular, identifying and supporting an in-school champion to have high power and high interest is recommended for future implementation strategies. This may reduce the need for intensive external support, thus improving intervention scalability., (© 2022. The Author(s).)

Background: In 2017, the provincial government of British Columbia (BC) implemented a mandatory policy outlining Active Play Standards (AP Standards) to increase physical activity (PA) levels, sedentary and motor skills among children attending licensed childcare centers. Concurrently, a capacity-building initiative was launched to help implement policies and practices supporting both PA and healthy eating (HE) in the early years. This study evaluated differences in center-level PA and HE policies and practices before and after the enforcement of the new provincial AP Standards., Methods: Using a repeat cross-sectional design, surveys were distributed to managers and staff of licensed childcare facilities serving children aged 2-5 years before (2016-2017 or 'time 1') and after (2018-2019 or 'time 2') implementation of the AP Standards across BC. The total sample included 1,459 respondents (910 and 549 respondents at time 1 and time 2, respectively). Hierarchical mixed effects models were used to examine differences in 9 and 7 PA/sedentary policies and practices, respectively, as well as 11 HE policies between time 1 and time 2. Models controlled for childcare size and area-level population size, education, and income., Results: Compared to centers surveyed at time 1, centers at time 2 were more likely to report written policies related to: fundamental movement skills, total amount of Active Play (AP) time, staff-led AP, unfacilitated play/free play, total amount of outdoor AP time, limiting screen time, breaking up prolonged sitting, staff role modeling of PA, and training staff about PA (P < 0.01 for all 9 policies examined). Compared to time 1, centers at time 2 reported more frequent practices related to ensuring children engaged in at least 120 min of AP, 60 min of outdoor AP daily, and limiting screen time (P < 0.01 for 3 out of 7 practices examined). Despite no additional policy intervention related to HE, centers were more likely to report having written policies related to: HE education for children, encouraging new foods, having family-style meals, offering only milk or water, limiting the amount of juice served, staff role modeling of HE, limiting the types of foods at parties/celebrations and foods brought from home (P < 0.05 for 9 out of 11 HE policies)., Conclusion: Approximately a year after the implementation of a governmental policy targeting PA supported by a capacity-building initiative, childcare centers reported positive changes in all 9 PA/sedentary policies examined, all 3 out of 7 PA/sedentary practices and 9 out of 11 HE policies evaluated at the center-level., (© 2022.

Background: Parents play a key role in young children's physical activity and physical literacy development. Little research has explored parent-focused interventions to improve young children's physical literacy. We examined if a theory-based, feasible physical literacy training workshop (PLAYshop) for parents could improve their physical literacy knowledge and confidence and improve parenting practices related to facilitating the physical literacy development of their preschool-aged child (3-5 years). The secondary objective was to explore implementation facilitators and barriers., Methods: We conducted a pragmatic controlled trial in two Canadian cities (Edmonton and Victoria) from November 2019 - March 2020. A total of 143/151 parents were eligible and assigned to intervention (n = 71) or control group (n = 72). The PLAYshop included: (i) a 75-min in-person workshop with interactive activities and physical literacy educational messages, (ii) educational materials, (iii) an equipment pack, and (iv) two post-workshop booster emails. Surveys measured parents' knowledge and confidence at baseline and follow-up. Application of PLAYshop concepts and implementation facilitators and barriers were explored with interviews of parents and workshop leaders. Repeated measures ANOVAs and thematic analyses were completed., Results: Parents' knowledge and confidence improved significantly over time; intervention group changes were significantly greater than control group changes (p < 0.001; ɳ 2  = .32). Parents applied PLAYshop concepts at-home, including child-led play, making activities fun, and promoting child manipulative and locomotor skills. Time was a key parental implementation barrier. Program implementation issues varied by context (location and participants)., Conclusions: PLAYshop participation changed parents' physical literacy knowledge and confidence and physical literacy enhancing play with their children. Implementation feasibility was high. The findings from this real-world trial highlight an efficacious and scalable intervention that warrants further testing., Trial Registration: ClinicalTrials.gov: NCT04394312 .

Objectives: To assess if a multi-strategy intervention effectively increased weekly minutes of structured physical activity (PA) implemented by classroom teachers at 12 months and 18 months., Methods: A cluster randomised controlled trial with 61 primary schools in New South Wales Australia. The 12-month multi-strategy intervention included; centralised technical assistance, ongoing consultation, principal's mandated change, identifying and preparing school champions, development of implementation plans, educational outreach visits and provision of educational materials. Control schools received usual support (guidelines for policy development via education department website and telephone support). Weekly minutes of structured PA implemented by classroom teachers (primary outcome) was measured via teacher completion of a daily log-book at baseline (October-December 2017), 12-month (October-December 2018) and 18-month (April-June 2019). Data were analysed using linear mixed effects regression models., Results: Overall, 400 class teachers at baseline, 403 at 12 months follow-up and 391 at 18 months follow-up provided valid primary outcome data. From baseline to 12-month follow-up, teachers at intervention schools recorded a greater increase in weekly minutes of PA implemented than teachers assigned to the control schools by approximately 44.2 min (95% CI 32.8 to 55.7; p<0.001) which remained at 18 months, however, the effect size was smaller at 27.1 min (95% CI 15.5 to 38.6; p≤0.001)., Conclusion: A multi-strategy intervention increased mandatory PA policy implementation. Some, but not all of this improvement was maintained after implementation support concluded. Further research should assess the impact of scale-up strategies on the sustainability of PA policy implementation over longer time periods., Trial Registration Number: Australian New Zealand Clinical Trials Registry (ACTRN12617001265369)., Competing Interests: Competing interests: Authors NN, RS, KG, NM, MP, RJ, VA, JW and LW receive salary support from Hunter New England Local Health District, which contributes funding to the project outlined in this study.

Background: Increased outdoor play time in young children is associated with many health and developmental benefits. This study aims to evaluate the impact of a multi-strategy implementation strategy delivered at scale, to increase opportunities for outdoor free play in Early Childhood Education and Care (ECEC) services., Methods: The study will employ a parallel-group randomised controlled trial design. One hundred ECEC services in the Hunter New England region of New South Wales, Australia, will be recruited and randomised to receive either a 6-month implementation strategy or usual care. The trial will seek to increase the implementation of an indoor-outdoor routine (whereby children are allowed to move freely between indoor and outdoor spaces during periods of free play), to increase their opportunity to engage in outdoor free play. Development of the strategy was informed by the Behaviour Change Wheel to address determinants identified in the Theoretical Domains Framework. ECEC services allocated to the control group will receive 'usual' implementation support delivered as part of state-wide obesity prevention programs. The primary trial outcome is the mean minutes/day (calculated across 5 consecutive days) of outdoor free play opportunities provided in ECEC services measured at baseline, 6-months (primary end point) and 18-months post baseline. Analyses will be performed using an intention-to-treat approach with ECEC services as the unit of analysis, using a linear mixed effects regression model to assess between-group differences. A sensitivity analysis will be undertaken, adjusting for service characteristics that appear imbalanced between groups at baseline, and a subgroup analysis examining potential intervention effect among services with the lowest baseline outdoor free play opportunities., Discussion: Identifying effective strategies to support the implementation of indoor-outdoor routines in the ECEC setting at scale is essential to improve child population health., Trial Registration: Australian New Zealand Clinical Trials Registry ( ACTRN12621000987864 ).

Background: Early childhood educators (ECEs) influence young children's early uptake of positive health behaviours in childcare settings and serve as important daytime role models. As such, it is imperative that post-secondary early childhood education programs provide students with the foundational knowledge and professional training required to confidently facilitate quality active play opportunities for young children. The primary objective of the Training pre-service EArly CHildhood educators in physical activity (TEACH) study is to develop and implement an e-Learning course in physical activity and sedentary behaviour to facilitate improvements in: pre-service ECEs' self-efficacy and knowledge to lead physical activity and outdoor play opportunities and minimize sedentary behaviours in childcare. This study will also explore pre-service ECEs' behavioural intention and perceived control to promote physical activity and outdoor play, and minimize sedentary behaviour in childcare, and the implementation of the e-Learning course., Methods/design: A mixed-methods quasi-experimental design with three data collection time points (baseline, post-course completion, 3-month follow-up) will be employed to test the e-Learning course in early childhood education programs ( n = 18; 9 experimental, 9 comparison) across Canada. Pre-service ECEs enrolled in colleges/universities assigned to the experimental group will be required to complete a 4-module e-Learning course, while programs in the comparison group will maintain their typical curriculum. Pre-service ECEs' self-efficacy, knowledge, as well as behavioural intention and perceived behavioural control will be assessed via online surveys and module completion rates will be documented using website metrics. Group differences across timepoints will be assessed using linear mixed effects modelling and common themes will be identified through thematic analysis., Discussion: The TEACH study represents a novel, evidence-informed approach to address the existing gap in physical activity and sedentary behaviour-related education in Canadian post-secondary early childhood education programs. Moreover, e-Learning platforms, can be employed as an innovative, standardized, and scalable way to provide ECEs with consistent training across jurisdictions.

Background: Childcare-based physical activity (PA) and sedentary behavior (SB) interventions have traditionally used in-person training to supplement early childhood educators' (ECEs) knowledge and confidence to facilitate physically active programming for the children in their care. However, this method of delivery is resource-intensive and unable to reach a high number of ECEs. The purpose of the Training pre-service EArly CHildhood educators in PA (TEACH) pilot study was to test the implementation (e.g., fidelity, feasibility, acceptability) of an e-Learning course targeting PA and SB among a sample of pre-service (i.e., post-secondary students) and in-service (i.e., practicing) ECEs in Canada., Methods: A pre-/post-study design was adopted for this pilot study, and implementation outcomes were assessed cross-sectionally at post-intervention. Pre-service ECEs were purposefully recruited from three Canadian colleges and in-service ECEs were recruited via social media. Upon completing the e-Learning course, process evaluation surveys (n = 32 pre-service and 121 in-service ECEs) and interviews (n = 3 pre-service and 8 in-service ECEs) were completed to gather ECEs' perspectives on the e-Learning course. Fidelity was measured via e-Learning course metrics retrieved from the web platform. Descriptive statistics were calculated for quantitative data, and thematic analysis was conducted to analyze qualitative data., Results: Moderate-to-high fidelity to the TEACH study e-Learning course was exhibited by pre-service (68%) and in-service (63%) ECEs. Participants reported that the course was highly acceptable, compatible, effective, feasible, and appropriate in complexity; however, some ECEs experienced technical difficulties with the e-Learning platform and noted a longer than anticipated course duration. The most enjoyed content for pre- and in-service ECEs focused on outdoor play (87.5% and 91.7%, respectively) and risky play (84.4% and 88.4%, respectively)., Conclusions: These findings demonstrate the value of e-Learning for professional development interventions for ECEs. Participant feedback will be used to make improvements to the TEACH e-Learning course to improve scalability of this training., (© 2022. The Author(s).)

Background: Early childhood educators (ECEs) are the primary daytime role models for many young children, and are responsible for facilitating physical activity (PA) opportunities and minimizing sedentary behaviour (SB) in childcare. However, they have reportedly received little related education in their pre-service training. The purpose of the Training pre-service EArly CHildhood educators in physical activity (TEACH) pilot study was to explore changes in pre- and in-service ECEs' knowledge, self-efficacy, behavioural intention, and perceived behavioural control following the TEACH e-Learning course in PA and SB., Methods: Pre-service ECEs were purposefully recruited from three Canadian colleges, while in-service ECEs were recruited via social media. A pre-post study design was used. ECEs completed two online surveys; one prior to, and one immediately following the completion of the TEACH e-Learning course (~ 5 h). Descriptive statistics were reported, and McNemar Chi-Square tests and paired samples t-tests were used to examine changes in ECEs' question-specific, and total knowledge scores, respectively. Wilcoxon Signed Ranks tests were employed to examine changes in self-efficacy, behavioural intention, and perceived behavioural control., Results: Both pre- (n = 32) and in-service (n = 121) ECEs significantly increased their total knowledge scores from pre- to post-course completion (p < .05*). Significant positive changes in self-efficacy (p < .025*), behavioural intention (p < .007*), and perceived behavioural control (p < .007*) were demonstrated by in-service ECEs following course completion, while only select composite scores within these tools were significant among pre-service ECEs., Conclusions: These findings provide preliminary evidence of the potential efficacy of the e-Learning course at improving ECEs' knowledge, self-efficacy, behavioural intention, and perceived behavioural control to support PA and minimize SB in childcare. Following the success of the pilot study, testing the effectiveness of the TEACH e-Learning course on a larger scale, with a comparison group, is warranted prior to recommending broader dissemination of the training in pre-service ECE programs and for in-service ECE professional learning., (© 2022.

As providers of community-based physical activity programs, recreation and sports facilities serve as an important resource for health promotion. Unfortunately, the food environments within these settings often do not reflect healthy eating guidelines. This study sought to describe facilitators and barriers to implementing provincial nutrition guidelines in recreation and sports facilities in three Canadian provinces with nutrition guidelines. Semi-structured interviews were analysed thematically to identify facilitators and barriers to implementing provincial nutrition guidelines. Facilitators and barriers were then categorised using a modified "inside out" socio-ecological model that places health-related and other social environments at the centre. A total of 32 semi-structured interviews were conducted at two time-points across the three guideline provinces. Interview participants included recreation staff managers, facility committee or board members and recreation volunteers. Eight facilitators and barriers were identified across five levels of the inside out socio-ecological model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Findings reinforce the importance of top down (clear expectations regarding guideline implementation at the time of approval) and bottom up (need for buy-in from multiple stakeholders) approaches to ensure successful implementation of nutrition guidelines. The application of a modified socio-ecological model allowed for a more nuanced understanding of leverage points to support successful guideline implementation. Lay summary Healthy eating is an important behaviour for preventing chronic diseases. Supporting people to access healthy foods in places where they live, learn, work or play is a public health priority. Recreation and sports facilities are a setting where people can be physically active. Unfortunately, the food environment in these settings may not reflect nutrition guidelines. In this study, we interviewed key stakeholders from recreation and sports facilities in three Canadian provinces who had put guidelines for healthy eating in place. We used a specific framework to do this called the inside out socio-ecological model. Eight facilitators and barriers were identified using this model. Facilitators included provincial or municipal expectations of guideline implementation, clear communication to staff around guideline directives and the presence of a champion within the community or facility who supported guideline implementation. Barriers included unhealthy food culture within community, competition from other food providers and issues within food service contracts that undermined healthy food provision. Our findings can help people working in recreation and sports facilities to identify issues that may help or hinder healthy food provision in these settings., (© The Author(s) 2021.

Canadian, municipally funded recreation/sport facilities typically have unhealthy food environments. Ontario, unlike some provinces, lacks a voluntary recreation facility nutrition policy. This study assessed the healthfulness of food environments and vending sales in 16 Ontario recreation/sport facilities and, secondarily, compared data from facilities within municipalities that banned versus permitted plastic bottled-water sales (water-ban, n = 8; water, n = 8) to test the nutritional effects of environmental policy. Concession and vending packaged food/beverage offerings and vending sales were audited twice, eighteen months apart. The products were categorized using nutrition guidelines as Sell Most (SM) , Sell Sometimes (SS) , and Do Not Sell (DNS) . Both water and water-ban facilities offered predominantly (>87%) DNS packaged food items. However, proportions of DNS and SM concession and vending beverages differed ( p < 0.01). DNS beverages averaged 74% and 88% of vending offerings in water and water-ban facilities, respectively, while SM beverages averaged 14% and 1%, respectively. Mirroring offerings, DNS beverages averaged 79% and 90% of vending sales in water versus water-ban facilities. Ontario recreation/sport facilities provided unhealthy food environments; most food/beverage offerings were energy-dense and nutrient-poor. Water bans were associated with increased facility-based exposure to DNS beverage options. A nutrition policy is recommended to make recreation facility food/beverage environments healthier and to mitigate unintended negative consequences of bottled-water bans.

Family-based physical activity (PA) interventions have proven effective in modifying PA; yet, the underlying mechanisms are currently unclear. In this study, we follow-up upon prior trial data that showed changes to child moderate-to-vigorous PA (MVPA) as a result of a family education+planning intervention compared to an education-only condition. We examined parents' perceived family PA frequency, family PA social cognitions, and family PA habit over 26 weeks between the two conditions. One hundred and two parents (of children aged 6 to 12 yrs), were recruited through advertisements and randomized to either the planning + education condition (n = 52) or an education-only condition (n = 50). Self-reported family PA, and measures of theory of planned behaviour, planning intention, and habit were completed by the contact parent at baseline, six-week, 13-week, and 26-week time-periods. The education+planning intervention increased planning intention ( p <.01) and family PA ( p =.06) compared to the© education-only group. The effect of condition on the putative mediators did not explain these changes (all 95% CIs crossed 0), and family PA was associated with child MVPA only at 13 weeks ( p <.01). Intervention 20 assignment had a small indirect effect on family PA (favouring©the education+planning group) via Habit. Perceived behavioural©control and habit were consistent predictors of family PA ( p <.05), but not PA intention or planning intention ( p >.05). The planning+education intervention showed improved family PA and planning intention, yet null mediation results suggest that other variables from the family system (e.g., child motivation, other parent's motivation and plans) are likely needed to fully understand the intervention effects. The promotion of perceived behavioural control and habit to assist in family PA is recommended for future research in this population.

Background: Development of physical literacy, defined as "the motivation, confidence, physical competence, knowledge and understanding to value and take responsibility for engagement in physical activities for life," can support children's physically active behaviors and consequent health benefits. Little research has explored interventions to improve children's physical literacy, although substantive evidence shows parents play a key role in children's physically active behaviors and development of fundamental movement skills. The purpose of this study was to explore the feasibility of a novel, physical literacy program (the PLAYshop) designed to build parents' self-efficacy to support their child's physical literacy., Methods: A non-randomized, one-arm concurrent nested design was used. Thirty-five parents of young children (3-8 years of age) attended a 75-min workshop inclusive of interactive activities, educational messages, and the provision of resources focused on core physical literacy concepts. Pre- and post-workshop surveys used quantitative measures to assess parents' satisfaction, knowledge, confidence, and intention to adopt practices. Follow-up interviews qualitatively explored the implementation experiences of both parents and facilitators. Paired t tests and thematic analysis were undertaken., Results: Of the 33 eligible parents, 23 completed both pre- and post-workshop surveys. Follow-up interviews were completed with 11 parents and four workshop facilitators. Parents' self-reported knowledge and confidence to support their child's physical literacy development significantly increased after PLAYshop participation. The majority of parents were satisfied with the workshop and motivated to apply learnings at home with their child. Workshop facilitators identified seven workshop strengths (e.g., workshop champions and skilled facilitators) and four challenges (e.g., recruitment and unfavorable spaces). Limitations include the lack of control group and recruitment challenges., Conclusions: The PLAYshop was perceived positively by parents and facilitators and appeared to improve parent self-efficacy and intention to promote physical literacy with their child. Recruitment and attendance were key implementation challenges. The findings from this real-world study support the preliminary feasibility of the PLAYshop intervention and highlight areas to improve the intervention and recruitment prior to efficacy testing in a more rigorous trial format.

Action Schools! BC (AS! BC) was scaled-up from an efficacy trial to province-wide delivery across 11 years (2004-2015). In this study we: (1) describe strategies that supported implementation and scale-up; (2) evaluate implementation (teachers' physical activity (PA) delivery) and student's PA and cardiorespiratory fitness (CRF) within a cluster randomized controlled trial during years 2 and 3 of scale-up; and (3) assess relationships between teacher-level implementation and student-level outcomes. We classified implementation strategies as process, capacity-building or scale-up strategies. Elementary schools ( n = 30) were randomized to intervention (INT; 16 schools; 747 students) or usual practice (UP; 14 schools; 782 students). We measured teachers' PA delivery ( n = 179) using weekly logs; students' PA by questionnaire ( n = 30 schools) and accelerometry ( n = 9 schools); and students' CRF by 20-m shuttle run ( n = 25 schools). INT teachers delivered more PA than UP teachers in year 1 (+33.8 min/week, 95% CI 12.7, 54.9) but not year 2 (+18.8 min/week, 95% CI -0.8, 38.3). Unadjusted change in CRF was 36% and 27% higher in INT girls and boys, respectively, compared with their UP peers (year 1; effect size 0.28-0.48). Total PA delivered was associated with change in children's self-reported MVPA (year 1; r = 0.17, p = 0.02). Despite the 'voltage drop', scaling-up school-based PA models is feasible and may enhance children's health. Stakeholders must conceive of new ways to effectively sustain scaled-up health promoting interventions if we are to improve the health of students at a population level.

Effective evidence-informed family-based nutrition interventions for childhood obesity management are needed. (a) To assess the number and quality of published randomized controlled trials incorporating family-based nutrition interventions for childhood obesity (ages 5-18 years) management and (b) to identify intervention attributes (e.g., contact time, nutrition curricula, and behavior change strategies) used in successful interventions. Studies that met eligibility criteria were randomized controlled trials and family-based childhood obesity management interventions for children and adolescents ages 5-18 years old that included a healthy eating component and measured child dietary behaviors and/or parent dietary feeding practices. Six databases were searched: CINAHL complete, Cochrane Central Register of Controlled Trials, Health Source: Nursing/Academic Edition, MEDLINE with full text (PubMed), PsycINFO, SPORTDiscus, and ERIC (EBSCO Host). The validated Quality Assessment Tool for Quantitative Studies was used to assess study quality. Eight studies met eligibility criteria. Study quality analysis showed that blinding of the research teams (e.g., analysts, and those focused on data collection) and the use of age appropriate, valid, and reliable instruments were areas of concern. Successful nutrition interventions targeting children 5-18 years old, appear to include setting family-based goals, modifying home food environment, hands-on approaches to teaching nutrition (games, group-based activities), and fruit and vegetable vouchers. This review highlighted a limited amount of moderate to high quality evidence to suggest that family-based nutrition interventions can be successful in improving dietary behaviors and that interventions with positive outcomes had some components of nutrition curricula and strategies in common., (© Society of Behavioral Medicine 2020.

Background:  The aim of this study was to examine the lived experiences of teachers and administrators at two schools (one elementary Kindergarten-Grade 5 and one middle school, grades 6-8) following the 'naturalizing' of a portion of their schoolyard. Methods : A qualitative case study design was used. Focus groups and interviews allowed participants to express their rationale, identify implementation facilitators and barriers and critical processes/steps for realizing their naturalization goals. Researcher questions explored (1) factors which led to naturalizing the schoolyard, (2) key planning and process steps (3) challenges and successes experienced, and, (4) lessons learned. Findings : Six themes were identified as rationale for naturalizing including: re-integration of outdoor play into children's daily lives, pro-active mental health, opportunity for inclusion, nature as a positive space for learning, it fit with our values and principles, we had a need. Implementation was facilitated by having champions and support from multiple levels, adopting a phased approach, resources and having the buy-in to persevere over time. Significant challenges and 'how to' steps were also identified. Conclusions : Naturalizing schoolyards does not happen without a supportive context, significant time and effort. Implementation steps and issues were those commonly found in other school-based health promotion efforts.

Background: Beyond the often examined perceptions of competence and motor skill proficiency, perceived value and children's expectations for success are thought to affect engagement in physical activities. We used parallel mediation models to examine the direct effect of motor skill proficiency on participation in physical activities, as well as whether children's beliefs and value for physical activities mediated this relationship., Methods: The participants in this cross-sectional study were a total of 398 grade 3 children (201 girls) from 8 schools. Motor skills were assessed using the Test of Gross Motor Development-2, the Value Expectancy Questionnaire measured the psychological variables, and the Children's Assessment of Participation and Enjoyment measured physical activities., Results: Motor skill proficiency predicted all 3 psychological constructs for the boys and the girls, and boys' participation in physical activities. However, the psychological variables did not mediate the relationship between motor skills and participation among the boys. For the girls, task value mediated the relationship between motor skills and physical activity participation., Conclusion: It is possible that the girls are further along in their ability to reflect on their competence, successes, and failures; it is also possible that the lower motor skill levels of girls had a deleterious effect on their feelings about participating.

Objective: To identify the pathways through which external, parental, and adolescent factors influence adolescents' motivation to adopt healthy dietary behaviors., Methods: A total of 28 ethnically and socioeconomically diverse (25% White) families were interviewed in which adolescents (mean age = 12.7 years; 50% girls) and parents (mean age = 43.3 years; 68% mothers) were interviewed separately. Data were first analyzed thematically, and family summaries, supplemented with diagrams, were then used to identify the processes through which factors influenced adolescents' dietary behaviors., Results: The analyses identified 3 main motivational pathways (intrinsic motivation, extrinsic motivation, and amotivation), wherein variability and inconsistencies were observed across and within pathways. The unique combination of external factors, parenting profiles, as well as adolescents' willingness to be socialized by family members, differentiated these pathways from each other., Conclusions and Implications: Health interventions need to target the overall approaches that parents use to socialize their adolescent to make healthy food choices instead of targeting specific parenting practices., (Copyright © 2020 The Authors.

Background: The 'scale-up' of effective physical activity interventions is required if they are to yield improvements in population health. The purpose of this study was to systematically review the effectiveness of community-based physical activity interventions that have been scaled-up. We also sought to explore differences in the effect size of these interventions compared with prior evaluations of their efficacy in more controlled contexts, and describe adaptations that were made to interventions as part of the scale-up process., Methods: We performed a search of empirical research using six electronic databases, hand searched reference lists and contacted field experts. An intervention was considered 'scaled-up' if it had been intentionally delivered on a larger scale (to a greater number of participants, new populations, and/or by means of different delivery systems) than a preceding randomised control trial ('pre-scale') in which a significant intervention effect (p < 0.05) was reported on any measure of physical activity. Effect size differences between pre-scale and scaled up interventions were quantified ([the effect size reported in the scaled-up study / the effect size reported in the pre-scale-up efficacy trial] × 100) to explore any scale-up 'penalties' in intervention effects., Results: We identified 10 eligible studies. Six scaled-up interventions appeared to achieve significant improvement on at least one measure of physical activity. Six studies included measures of physical activity that were common between pre-scale and scaled-up trials enabling the calculation of an effect size difference (and potential scale-up penalty). Differences in effect size ranged from 132 to 25% (median = 58.8%), suggesting that most scaled-up interventions typically achieve less than 60% of their pre-scale effect size. A variety of adaptations were made for scale-up - the most common being mode of delivery., Conclusion: The majority of interventions remained effective when delivered at-scale however their effects were markedly lower than reported in pre-scale trials. Adaptations of interventions were common and may have impacted on the effectiveness of interventions delivered at scale. These outcomes provide valuable insight for researchers and public health practitioners interested in the design and scale-up of physical activity interventions, and contribute to the growing evidence base for delivering health promotion interventions at-scale., Trial Registration: PROSPERO CRD42020144842 .

Background: The purpose of this study was to evaluate the effectiveness of a 10-week blended family-based childhood obesity management program, relative to a wait-list control, in improving child body mass index (BMI) z-scores, child lifestyle behaviors, parental support for healthy eating and physical activity, and self-regulation for healthy eating and physical activity support. Methods: This study was registered as a randomized wait-listed controlled trial; however, due to low recruitment and program delivery logistics, this study transitioned into a quasi-experimental design. Families with children 8-12 years of age with a BMI ≥85th percentile for age and sex were recruited (October 2018 to March 2019) in British Columbia, Canada. The intervention provided families 10 weeks of in-person and online support on improving lifestyle behaviors. Results: Children's BMI z-scores were not significantly changed. Intervention group significantly improved their days of moderate-to-vigorous physical activity relative to control (0.75 ± 1.5; p  < 0.01; ηp 2  = 0.15); however, child dietary behaviors were not significantly changed. Relative to control, intervention group showed significant improvements in parental support for healthy eating (0.13 ± 0.36; p  < 0.05; ηp 2  = 0.06) and physical activity (1.0 ± 1.6; p  < 0.05; ηp 2  = 0.09) and self-regulation for healthy eating (2.0 ± 3.5; p  < 0.01; ηp 2  = 0.11) and physical activity support (2.0 ± 3.2; p  < 0.05; ηp 2  = 0.28). Conclusions: Preliminary evidence showed that the intervention was not effective in improving child BMI z-scores, but it was effective in promoting children's physical activity and parents' support behaviors. A longer study period may be required to change BMI z-scores. Clinical Trial Registration number: NCT03643341.

Purpose: Limited research has measured the effect of physical activity (PA) interventions on health-related quality of life (HRQoL) among pre-school-aged children. This study evaluates the effect of the Activity Begins in Childhood (ABC) cluster-randomized controlled trial designed to increase PA in the ages 3-5 years on HRQoL., Methods: This was a cluster-randomized controlled trial where the intervention group included PA education delivered to daycare providers only, or daycare providers and parents. In the current study, the two PA intervention groups were combined. The comparator group received standard daycare curriculum (COM). A total of 215 children were included (PA n = 161, COM n = 54). Parents completed the proxy Pediatric Quality of Life Inventory Generic Core Scale (PedsQL™ 4.0) to measure HRQoL at baseline and the end of the 6-month trial. HRQoL scores were analyzed as physical, psychosocial, and total domains. Baseline and 6-months measurements were compared for PA and COM groups, and mean changes in scores (95% confidence intervals) were measured using absolute values., Results: No between-group differences were observed for the physical (p = 0.17), psychosocial (p = 0.95) or total scores (p = 0.20). Paired comparisons showed that only the PA group improved psychosocial- (PA mean difference = 2.18 (0.20, 4.15), p = 0.03; COM mean difference = 2.05 (- 1.03, 5.13), p = 0.19) and total-HRQoL scores (PA mean difference = 2.83 (1.83, 3.84), p < 0.001; COM mean difference = 0.19 (- 1.78, 2.16), p = 0.84) after 6 months., Conclusion: Although the within-PA group analysis showed an improvement in psychosocial and total HRQoL scores from baseline, no between-group differences were observed in the HRQoL over time among children aged 3-5 years.

The transition to parenthood is associated with declines in moderate to vigorous physical activity (MVPA) and increases in light PA (LPA). One potential mechanism for this change in PA that occur at the onset of parenthood is housework. We examined housework load and PA levels of three cohorts of couples across 12 months recruited from Victoria, British Columbia, Canada between January 2007 and December 2011. Participants (N = 314; 102 not expecting a child, 136 expecting first-child, 76 expecting second child) completed baseline demographics and 7-day accelerometry, followed by assessments at 6 and 12 months. Hierarchical linear regression assessed the association between PA, housework, and perceptions of partner's workload. New fathers' but not new mothers' housework was positively related to their LPA at 12 months. Perceptions of partners' workload were positively related to new mothers LPA, and negatively related to new fathers MVPA at 12 months. Mediation analysis determined if perceived behavioral control accounts for the relationship between the discrepancy in housework between partners' PA. Results suggest that if a woman perceives their partner to do more housework their own PA increases, whereas for men their PA decreases. These findings highlight the importance of the division of housework on PA for both mothers and fathers.
