The Development, Short-Term Efficacy, And Pilot Implementation Of An E-Learning Course In Physical Activity And Sedentary Behaviour For Pre-Service Early Childhood Educators, Brianne Bruijns

Electronic Thesis and Dissertation Repository

The overarching purpose of this dissertation was to develop an e-Learning course in physical activity and sedentary behaviour and test its short-term efficacy and implementation among pre- and in-service early childhood educators (ECEs). The Delphi approach was adopted for Study 1, wherein a panel of international experts in physical activity and sedentary behaviour suggested topics for the course and, together with a panel of ECE experts, rated their importance. Study 2 employed a pre-post design to explore the changes in pre- and in-service ECEs’ physical activity and sedentary behaviour-related knowledge, self-efficacy, behavioural intention, and perceived behavioural control following course completion. …

Environmental Changes Following The Implementation Of The Childcare Physical Activity (Play) Policy, Victoria Tran

Electronic Thesis and Dissertation Repository

Environmental factors such as the infrastructure and equipment in childcare centres can influence the physical activity levels of young children. This study explored if implementing the Childcare PhysicaL ActivitY (PLAY) policy resulted in unintended environmental changes that were conducive to physical activity in childcare. Childcare centres were randomized to an experimental (n = 5) or control (n = 4) condition. Three Environment and Policy Assessment and Observation Self-Report (EPAO-SR) tools were used to measure 12 best practice items in relation to the childcare environment and early childhood educators’ (ECEs) practices. Descriptive statistics and mixed-effects logistics regression models were …

Optimizing The Carrot Rewards App: An Examination Of Team-Based Financial Incentives To Increase Walking, Emma Pearson

Electronic Thesis and Dissertation Repository

Mobile health applications (mHealth apps) targeting physical activity (PA) have increased in popularity, yet effectiveness is often limited by low engagement. This study examined the impact of adding a team-based feature, Step Together Challenges (STCs), to an existing incentive-based mHealth app (i.e., Carrot Rewards) on PA. A 24-week retrospective matched pairs study was conducted (n=61,170; pre-intervention: weeks 1-12; intervention: weeks 13-24). Participants who used STCs (experimental group) were matched with those who did not (controls). STC users could earn team incentives for collaboratively reaching individual daily step goals 10 times in seven days. Controlling for pre-intervention mean daily step count, …

Active And Safe Routes To School: Evaluating School Travel Planning To Support Children's Active Travel, Adrian Nicholas Buttazzoni

Electronic Thesis and Dissertation Repository

Most Canadian children are not achieving their daily recommended physical activity (PA) levels despite the many emotional, psychological, and physical benefits of PA. Walking or wheeling to/from school, or active school travel (AST), is a viable method for improving children’s daily participation in PA. In Canada, the Active and Safe Routes to School initiative promotes AST through its comprehensive School Travel Planning (STP) program. Utilizing a mixed-methods approach, broadly, this thesis investigates the i) implementation and ii) effectiveness of a regional, two-year STP program supporting AST. This thesis includes a systematic review of AST intervention models implemented in North America, …

Examining Geographic Variation In Children's Perceived Barriers To Physical Activity And The Implications On Behaviour, Leah Gabrielle Taylor

Electronic Thesis and Dissertation Repository

Low levels of physical activity among Canadian children has become a national public health issue. Recent research has suggested that children’s physical activity levels are associated with their perceptions of their everyday environments. A better understanding of the formation of these perceptions within different contexts is needed to explain the extent of the relationship. Using a multi-tool quantitative protocol, this thesis examines geographic variation in socio-ecological factors influencing children’s perceptions of barriers to PA, and the extent to which perceptions mediate the relationship of the environment and PA. Results indicate that perceptions form within contexts, and have an influence on …

Exploring The Influence Of Childcare Type On Physical Activity And Sedentary Time Of A Nationally Representative Sample Of Canadian Preschoolers, Julie Statler

Electronic Thesis and Dissertation Repository

A large number of Canadian children are enrolled in childcare, and they spend substantial time there. Capturing a national picture of the relationship between childcare type and physical activity (PA; i.e., light, moderate- to-vigorous, and total) and sedentary time (ST) in young children is needed. Using a nationally representative sample of preschoolers (aged 3-5 years), this cross-sectional study used cycles 3 and 4 of the Canadian Health Measures Survey. Childcare type (e.g., centre-, home-based childcare, home with parent, kindergarten) was reported by parents. Preschoolers wore an accelerometer for 7 consecutive days. Device and population-specific cut-points were applied to delineate PA …

Exploring The Physical Activity And Screen Viewing-Related Knowledge, Training, And Self-Efficacy Of Early Childhood Education Candidates, Brianne Bruijns

Electronic Thesis and Dissertation Repository

Early childhood educators (ECEs) greatly influence young children’s physical activity (PA) and screen viewing (SV) behaviours. This study explored the PA and SV-related knowledge (i.e., of important PA/SV concepts), training (i.e., PA/SV courses/content received), and self-efficacy (i.e., to facilitate PA and limit SV in childcare) of early childhood education students. A sample of 1,292 students from 61 Canadian colleges/universities completed the online survey. In general, students exhibited the least amount of knowledge regarding the link between SV and health. Further, 67.8% and 73.3% of students had not completed PA or SV courses during their post-secondary training, respectively, and students who …

Assessing Physical Activity And Sedentary Time In The Early Years, Leigh M. Vanderloo

Electronic Thesis and Dissertation Repository

The overall purpose of this dissertation was to explore young children’s (18 months to 5 years) physical activity and sedentary time. Study 1 assessed the physical activity and sedentary time among a sample of toddlers from London, Canada using two data processing approaches. Study 2 explored the impact of three different early learning environments, and their respective characteristics (e.g., staff behaviours, equipment, sedentary opportunities, etc.), on preschoolers’ activity levels. Study 3 examined differences in two popular accelerometers used to measure young children’s physical activity and sedentary time to better understand measurement discrepancies.

Study 1 revealed that toddlers engaged in 37.27 …

Exploring Mothers' Influence On Preschoolers' Physical Activity Levels And Sedentary Time, Alana M. Maltby

Electronic Thesis and Dissertation Repository

Physical activity (PA) patterns continue from childhood into adulthood; therefore, establishing healthy PA levels early is imperative. Mothers have been identified as influencing preschoolers’ activity behaviours; however, a holistic exploration of maternal influence is lacking. The purpose of this study was to explore maternal influence on preschoolers’ PA and sedentary time. Preschoolers (n = 30) and their mothers wore ActicalTM accelerometers, and mothers completed the adapted Environmental Determinants of Physical Activity in Preschool Children - Parent Survey. Direct entry regression analyses were conducted to explore maternal influence (e.g., support, enjoyment) on preschoolers’ activity levels. Maternal support was a significant predictor …

Awareness Of Physical Activity Levels And Sedentary Behaviour: An Assessment Of Awareness Of Physical Activity Levels And Sedentary Behaviour Among Parents And Children, Tripat Simran Kaur Grewal

Electronic Thesis and Dissertation Repository

The purpose of this study was to assess awareness of physical activity and sedentary behaviour among parents and children aged 10-13 years. Associations between awareness and factors including age, BMI, gender, and obesity status were also examined. A total of 53 parent-child dyads participated in the study. Agreement between parent and child subjective measures (self-report) and objectively measured physical activity was examined to determine awareness. Most parents (87%) and children (83%) overestimated child moderate-vigorous physical activity (MVPA) beyond 30 minutes/day. The majority of parents (87%) and children (85%) also underestimated child sedentary behaviour by at least 3 hours/day. Older children …
