Socioeconomic Patterning Of Physical Activity Among Middle-Aged To Older Adults, Jane Yuan

Electronic Thesis and Dissertation Repository

Regular physical activity is a well-known protective factor against chronic disease and strongly correlated with healthy aging. However, as physical activity levels tend to decline with age, there is a need to identify barriers which prevent older adults from being physically active. This thesis investigated the relationship between socioeconomic status and meeting physical activity guidelines of 150 minutes or more of moderate- to vigorous- intensity physical activity among middle-aged to older adults in Canada. Using cross-sectional data from the baseline assessment of the Canadian Longitudinal Study on Aging, block-wise multivariable logistic regression was performed to assess the association between socioeconomic …

Evaluating The Impact Of A Safe Exercise Training Workshop On Knowledge And Self-Efficacy To Manage Dysfunctional Exercise Among Eating Disorders Clinicians At Alsana Eating Disorders Center, Danika A. Quesnel

Electronic Thesis and Dissertation Repository

Engaging in dysfunctional exercise (DEX) is detrimental to eating disorders (EDs) prognosis, although common amongst clients. Though nutritionally supported exercise can improve ED treatment outcomes, without negatively impacting weight restoration, clinicians remain hesitant to address DEX, perhaps due to a lack of information and training. The current study examined the effects of a Safe Exercise at Every Stage (SEES) training on clinician knowledge and self-efficacy in managing DEX in ED treatment. Eating disorders clinicians completed measures before (n = 96) and after (n = 44) SEES training to assess their knowledge and self-efficacy around treating DEX, with a …

Investigating Physiological Determinants Of Mental Health In Children With Cerebral Palsy, Daniela A. Testani

Electronic Thesis and Dissertation Repository

Background

Fifty-seven percent of children with cerebral palsy (CP) experience mental health symptoms including symptoms of anxiety and depression. Although CP is non progressive, secondary conditions can have progressive effects on an individuals’ functional abilities. Particularly, untreated mental health symptoms can negatively affect a child’s quality of life. Children with CP also experience fatigue, pain, poor physical activity, and sleep disturbances. The presence of these physiological symptoms, separate and in combination, may impact mental health; however, it has not been systematically examined. Identifying factors that contribute to mental health symptoms may prevent the maintenance of these issues into adulthood.

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 …
