Physical Activity Levels In Total Hip Arthroplasty Comparing The Direct Anterior Approach To The Direct Lateral Approach: A Prospective Cohort Study, Abdulaziz N. Aljurayyan

Electronic Thesis and Dissertation Repository

Total hip arthroplasty (THA) is a cost-effective surgical procedure to treat patients with end-stage hip arthritis with high patient satisfaction. Different surgical approaches to the hip have been used to successfully perform THA. However, the role of these surgical approaches on physical activity and early functional recovery in THA patients remains controversial.

In this thesis, we prospectively evaluated physical activity levels in patients with end-stage hip OA whom are undergoing elective THA. The primary focus was to evaluate the impact of different surgical approaches on physical activity levels as a measure of functional recovery in the immediate postoperative period.

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 …

Change In Preschoolers’ Health-Related Quality Of Life Following The Implementation Of A Childcare Physical Activity Intervention, Stephanie Truelove

Electronic Thesis and Dissertation Repository

Being active offers many physical and emotional benefits contributing to a higher health-related quality of life (HRQOL); however, this relationship remains unexplored among preschoolers. The purpose of this study was to examine the impact of the Supporting Physical Activity in the Childcare Environment intervention on preschoolers’ HRQOL. Childcare centres were randomized to the experimental (n = 11) or control (n = 11) condition and preschoolers’ HRQOL was measured using the parent-report Pediatric Quality of Life Inventory 4.0 (three subscales: physical, psychosocial, and total) at baseline and at 8-weeks. Three univariate ANCOVAs were conducted to compare HRQOL (experimental and …

The Association Between Social Cohesion And Physical Activity In Communities Across Canada: A Multilevel Analysis, Calvin Yip

Electronic Thesis and Dissertation Repository

Background: In Canada, only 15% of adults meet physical activity guidelines for optimal health. Previous research has suggested that social cohesion may promote physical activity.

Objective: To assess the association between social cohesion and physical activity among adults aged 18 to 64 years in Canada.

Methods: Data from the 2009-2010, 2011-2012, and 2013-2014 cycles (N=245,150) of the Canadian Community Health Survey were used. Physical activity level was operationalized using average daily energy expenditure, social cohesion was determined by self-rated sense of belonging to the local community, and communities were represented by Canada’s Forward Sortation Areas. Multilevel regression models were used …

Children's Physical Activity And The Built Environment: The Impact Of Neighbourhood Opportunities And Contextual Environmental Exposure, Christine A. Mitchell

Electronic Thesis and Dissertation Repository

Childhood obesity rates have risen dramatically since 1981, in part due to decreased physical activity (PA) levels. Research suggests that PA is influenced in part by an individual’s exposure to and engagement with their built environment. Using a multi-tool protocol, this thesis examines how (a) neighbourhood opportunities facilitate or constrain children’s moderate-to-vigorous PA (MVPA) and (b) contextual environmental exposure facilitates or constrains children’s MVPA. Results suggest that children’s MVPA is influenced by their built environment, but more so by the contextual environments that they are directly exposed to rather than their overall neighbourhood settings. Children are mobile and unlikely to …
