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 …

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 …
