Investigating Elementary School Food Programs: Impacts On Child Knowledge And Dietary Behaviours, Paige Colley

Electronic Thesis and Dissertation Repository

Good nutrition is an important part of maintaining a healthy lifestyle. A balanced diet can promote positive health outcomes, protecting against health problems caused by nutritional deficiencies. Canada has reported poor diet quality and high rates of overweight and obesity among children. Obesity has been linked to several non-communicable diseases including type 2 diabetes, heart disease, and some forms of cancer. Efforts to improve lifelong, healthy eating behaviours must be implemented.

This dissertation investigated the impacts of school food programming on child nutrition. A Centrally Procured School Food Program (CPSFP) was implemented at 30 elementary schools in Southwestern Ontario, Canada. …

The Application Of Self-Administered Nutrition Screening Tools And Evaluations Of The Impact Of Malnutrition On Quality Of Life In Individuals With Head And Neck Cancer, Mark J. P. Lynch

Electronic Thesis and Dissertation Repository

Abstract

Background: Individuals with head and neck cancer (HNCa) are at an increased risk of malnutrition. Therefore, self-administered nutrition screens which attempt to address their nutritional concerns may yield benefits for treatment outcomes and quality of life (QOL).

Methods: 34 participants (26 men, 8 women) completed one demographic and two QOL surveys, two nutrition self-screening tools, a nutrition assessment and an ease-of-use questionnaire. Results of the screens were compared to those of the assessment, and relationships between QOL, nutrition status, and demographics were examined.

Results: 32.3% of participants were identified as nutritionally compromised. The sensitivity and specificity for the PG-SGA …

Nicotinamide Riboside Delivery Generates Nad+ Reserves To Protect Vascular Cells Against Oxidative Damage, Krista M. Hawrylyshyn

Electronic Thesis and Dissertation Repository

The ability of vascular cells to withstand oxidative insults is critical to vascular health. NAD⁺, which drives poly (ADP-ribose) polymerase (PARP) and sirtuin (SIRT) reactions, can be compromised and strategies for overcoming this limitation in the vasculature do not exist. This study determines if nicotinamide riboside (NR) delivery can augment NAD⁺ stores and fuel resistance to oxidative stress. I established that oxidative-stress insult on vascular cells decreased NAD⁺ levels, accompanied by a striking increase in nuclear PAR-chain accumulation. PARP inhibition abolished PAR-chain formation and preserved NAD⁺ levels, establishing PARP in NAD⁺ consumption in this …

Evaluating The Impact Of Two Different Methods Of Diabetes Self-Management Education On Knowledge, Attitude, And Behaviours Of Patients With Type 2 Diabetes Mellitus, Laura B. Briden

Electronic Thesis and Dissertation Repository

This study compared the effectiveness of diabetes self-management education (DSME) methods by examining changes in knowledge, attitude, and behaviour (KAB) after receiving education. Participants from a convenience sample were randomized into two groups, one receiving education through conversation maps and the other through traditional group education. Participants’ knowledge and attitude changes were measured by using a repeated measures pre-test/post-test design and changes in Hb A1c were observed. Focus groups were conducted after education was received to obtain perceptions and self-reported behaviour changes. Significant knowledge and attitude score changes were observed in the conversation map group after education. When comparing the …

Planning, Implementation, And Formative Evaluation Of A Food Literacy Program, Heather M. Thomas

Electronic Thesis and Dissertation Repository

The overall purpose of this dissertation was to examine the planning, implementation, and formative evaluation of a community-based food literacy program for youth. Article 1 provided a summary of the community-based cooking program for at-risk youth. Objectives included the provision of applied food literacy and cooking skills education augmented with fieldtrips to local farms. Eight at-risk youth (five girls and three boys, mean age = 14.6) completed the intervention. Post intervention, five of eight participants completed in-depth interviews about their experiences.

Article 2 was a formative evaluation of the cooking program focused on gaining an understanding of participants’ (i.e., at-risk …
