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. …

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 …

Move More Mommy: A Web-Based Physical Activity Intervention For Postnatal Women (Pilot Study), Sarah Gray

Electronic Thesis and Dissertation Repository

Despite the many benefits of physical activity, postnatal women are not currently meeting Health Canada Guidelines of 150 minutes per week of moderate-vigorous physical activity. This study, Move More Mommy, used a mixed methods design to test the feasibility and acceptability of a web-based intervention combined with a group mediated cognitive behavioural approach, and it’s effectiveness to increase physical activity, self-efficacy, and group cohesion among postnatal women. Participants received an 8-week intervention delivered through 8 group exercise classes and a purpose built website. From baseline to post-intervention, participants significantly increased self-reported physical activity levels and group cohesion. Objectively measured physical …

Parents' Perceptions Of Activity Restrictions In Children With Epilepsy: First Two Years Post-Diagnosis, Nathan C. King

Electronic Thesis and Dissertation Repository

Children with epilepsy are less physically and socially active than their peers. The objective is to explore whether parents represent a barrier to children’s activity, by examining associations between child and family factors and parents’ perceptions of epilepsy-related activity restrictions. Data were from the Health Related Quality of Life in Children with Epilepsy Study, a longitudinal study of children 4-12 years old with new-onset epilepsy. Parents reported on activity restrictions and family factors and neurologists reported on epilepsy-related characteristics at baseline, 6, 12, and 24 months. Linear mixed models were used to model relationships among child and family factors and …

The Influence Of The Childcare Environment On Physical Activity Among Preschool-Aged Children: A Feasibility Study, Leigh M. Vanderloo

Electronic Thesis and Dissertation Repository

This study sought to: (1) measure moderate-vigorous physical activity (PA) levels of a sample of preschoolers; (2) assess which attributes (e.g., space, equipment, policies) within centre-based childcare environments influence PA; and, (3) pilot the methodology to ensure the feasibility of undertaking a full-scale study. Thirty-one preschoolers from five childcare centres across London, Canada participated. Actical® accelerometers were worn by participants for one day during childcare hours to assess activity levels using a 15-second epoch length. The Environment and Policy Assessment and Observation instrument was used to conduct a full-day evaluation of the childcare environment. On average, participants engaged in 11.45 …

Physical Activity Among Latino Children In London, Ontario: An Assessment Of Physical Activity Levels, Sedentary Behaviours, And Physical Activity-Related Barriers And Facilitators, Gillian E. Mandich

Electronic Thesis and Dissertation Repository

The purpose of the study was to assess the physical activity (PA) levels, sedentary behaviours, and PA-related barriers and facilitators of a sample of Latino children in London, Canada. Forty boys and 34 girls (mean age = 11.4 years) completed questionnaires related to PA levels, sedentary behaviours, and PA-related barriers and facilitators, and 64 of these children wore an accelerometer for 4 consecutive days. Children spent an average of 53 minutes per day in moderate-to-vigorous PA. The average daily sedentary time for participants was 8.6 hours, and subjective measures revealed that participants spent 3.8 hours per day in front of …
