Identifying Differences In Nutrition-Related Learning Interests Of Adolescent Students, Margaret Miller, Donna Barwood, Michael Furfaro, Julie Boston, Sandra Smith, Martin Masek

Research outputs 2014 to 2021

© 2021 The Authors. Journal of School Health published by Wiley Periodicals LLC. on behalf of American School Health Association. BACKGROUND: In this study, we examined nutrition-related topics among adolescent students attending schools with different Indices of Community Socio-Educational Advantage (ICSEA). METHOD: Participating students (N = 206) from 5 schools in Western Australia completed a paper-based questionnaire on nutrition-related topics. Frequencies and independent chi-square tests were used to identify differences between sexes and school ICSEA. RESULTS: Of the participating students, 75% were interested in learning about 8 of 16 topics. We found statistically significant differences by sex (p < .01) for “Eating the right foods for preventing illness and disease,” “Eating the right food for being active” among girls, and “Reducing food waste” among boys. We also noted differences by school ICSEA. CONCLUSION: Acknowledging sex and socioeducational differences in teaching and learning may help teachers to engage adolescent students in nutrition education.

Research outputs 2014 to 2021

Vitamin K content of foods is known to vary substantially by geographical location. In Australia, no Vitamin K database of food exists, thereby creating ambiguity when trying to develop national dietary intake guidelines. This investigation aimed to develop a Vitamin K database for commonly consumed foods that are commercially available in Australian supermarkets. The Vitamin K1 (phylloquinone; PK) and K2 (menaquinone; MK4, MK7) content of 60 foods known to contain Vitamin K were assessed (e.g., vegetables fruits, oils, animal products, dairy and fermented foods). A liquid chromatography with tandem mass spectrometry (LCMS/MS) method was developed and used to measure PK …

Proteome Analysis And Epitope Mapping In A Commercial Reduced-Gluten Wheat Product, Mitchell G. Nye-Wood, Angela Juhasz, Utpal Bos, Michelle L. Colgrave

Research outputs 2014 to 2021

Gluten related disorders, such as coeliac disease, wheat allergy and baker's asthma are triggered by proteins present in food products made from wheat and related cereal species. The only treatment of these medical illnesses is a strict gluten-free diet; however, gluten-free products that are currently available in the market can have lower nutritional quality and are more expensive than traditional gluten containing cereal products. These constraints have led to the development of gluten-free or gluten-reduced ingredients. In this vein, a non-GMO wheat flour that purports to contain “65% less allergenic gluten” was recently brought to market. The present study aims …

Nutrition, Body Composition And Physical Activity In Malignant Pleural Disease: Associations With Patient Outcomes And Response To An Exercise Intervention, Emily Jeffery

Theses: Doctorates and Masters

Background: Patients with malignant pleural disease (MPD) have advanced cancer and high symptom burden. Goals of patient care are to optimise health-related quality-of-life (HR-QoL) and participation in daily physical activities. Supportive care interventions such as nutrition and exercise could offer benefit to patients. However, there is a lack of information on the prevalence of low muscle mass (i.e., pre-sarcopenia), malnutrition, inactivity and poor physical functioning in patients with MPD. Additionally, little is known about the factors associated with development of pre-sarcopenia and malnutrition or their associations with patient outcomes.

Purpose: The objectives were to: 1) characterise physical activity levels and …

Finding Companionship On The Road Less Travelled: A Netnography Of The Whole Food Plant-Based Aussies Facebook Group, Robyn Chuter

Theses : Honours

Chronic conditions are now the leading contributors to the burden of disease and associated healthcare expenditure in Australia. Wholefood plant-based diets are an evidence-based approach to the prevention, management and even reversal of many types of chronic disease. However, numerous practical, cognitive, social and intrapersonal barriers inhibit the ‘mainstreaming’ of plant-based diets (PBDs). Online communities may provide the informational, emotional and social support to help members overcome these barriers. However, there is a paucity of research on both the support needs of people attempting to follow PBDs in Australia, and the role that online community membership plays in providing this …

Antibiotic Resistance In Gram Negative Bacteria Isolated From Fish Sold In Western Australia, Hannah Kathleen Robinson

Theses: Doctorates and Masters

Background Information The global misuse and overuse of antibiotics in human medicine and the animal production industry is contributing to the development of antibiotic resistance in bacteria. This is a serious threat to modern medicine and public health. Antibiotic resistant organisms can cause severe infections in humans which are difficult to treat, and in some cases impossible to resolve which can lead to premature death. Several studies have been conducted across the globe to assess the use of antibiotics in the seafood industry and the associated health risks, however, limited studies have recently explored this risk in an Australian setting. …

Ward, Richard L. Prince, Joshua R. Lewis, Amanda Devine, Kevin D. Croft, Jonathan M. Hodgson, Catherine P. Bondonno

Research outputs 2014 to 2021

Background

Dietary nitrate is an important source of nitric oxide (NO), a molecule critical for cardiovascular health. Nitrate is sequentially reduced to NO through an enterosalivary nitrate-nitrite-NO pathway that involves the oral microbiome. This pathway is considered an important adjunct pathway to the classical l-arginine–NO synthase pathway.

Objective

The objective of this study was to systematically assess the evidence for dietary nitrate intake and improved cardiovascular health from both human and animal studies.

Design

A systematic literature search was performed according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines by using key search terms in Medline and …

Including Pork In The Mediterranean Diet For An Australian Population: Protocol For Arandomised Controlled Trial Assessing Cardiovascular Risk And Cognitive Function, Alexandra T. Wade, Courtney R. Davis, Kathryn A. Dyer, Jonathan M. Hodgson, Richard Woodman, Hannah A. Keage, Karen J. Murphy

Research outputs 2014 to 2021

Background

The Mediterranean diet is characterised by the high consumption of extra virgin olive oil, fruits, vegetables, grains, legumes and nuts; moderate consumption of fish, poultry, eggs and dairy; and low consumption of red meat and sweets. Cross sectional, longitudinal and intervention studies indicate that a Mediterranean diet may be effective for the prevention of cardiovascular disease and dementia. However, previous research suggests that an Australian population may find red meat restrictions difficult, which could affect long term sustainability of the diet.

Methods

This paper outlines the protocol for a randomised controlled trial that will assess the cardiovascular and cognitive …

A Mediterranean Diet To Improve Cardiovascular And Cognitive Health: Protocol For A Randomised Controlled Intervention Study, Alexandra T. Wade, Courtney R. Davis, Kathryn A. Dyer, Jonathan M. Hodgson, Richard J. Woodman, Hannah A.D. Keage, Karen J. Murphy

Research outputs 2014 to 2021

The Mediterranean diet has demonstrated efficacy for improving cardiovascular and cognitive health. However, a traditional Mediterranean diet delivers fewer serves of dairy and less dietary calcium than is currently recommended in Australia, which may limit long-term sustainability. The present study aims to evaluate whether a Mediterranean diet with adequate dairy and calcium can improve cardiovascular and cognitive function in an at-risk population, and thereby reduce risk of cardiovascular disease (CVD) and cognitive decline. A randomised, controlled, parallel, crossover design trial will compare a Mediterranean diet supplemented with dairy foods against a low-fat control diet. Forty participants with systolic blood pressure …

Development Of The Meal Framework: A Multiliteracies Approach To Engaging Adolescents In Nutrition Education, Samantha Lee Baker

Theses: Doctorates and Masters

Establishing and maintaining a healthy diet is integral in promoting optimal health, growth and development. Moreover, the food choices we make and dietary behaviours we adopt are a reflection of the multiple personal, interpersonal and environmental factors to which we are exposed. Consequently, changing food habits and dietary behaviour is complex and requires the implementation of multifaceted public health strategies. Comprehensive nutrition education provided to adolescents during their school years is one such approach.

Adolescence is a period of rapid psychological and physiological changes. At a socioemotional level, there is a decreased level of dependence on parents and a greater …

Food Insecurity And Fruit And Vegetable Consumption Among Regional And Remote Western Australian Children: Determinants, Prevalence And Predictors, Stephanie Louise Godrich

Theses: Doctorates and Masters

Living in a community with adequate availability of nutritious food, and the capacity to access and utilise it, are key food security determinants (FSD). However, inequities relating to these determinants exist between regional and remote Western Australian (WA) communities, particularly regarding fruit and vegetables (F&V). This negatively impacts vulnerable populations, especially children. In order to understand determinants, prevalence and predictors of F&V and food security (FS), three concepts were explored in this PhD; (1) F&V consumption among regional and remote WA children (including determinants of F&V consumption, quantities, types, varieties of F&V consumed); (2) FS among regional and remote WA …

Research outputs 2014 to 2021

Reduced fat dairy products are generally recommended for adults and children over the age of two years. However, emerging evidence suggests that dairy fat may not have detrimental health effects. We aimed to investigate prospective associations between consumption of regular versus reduced fat dairy products and cardiometabolic risk factors from early to late adolescence. In the West Australian Raine Study, dairy intake was assessed using semi-quantitative food frequency questionnaires in 860 adolescents at 14 and 17-year follow-ups; 582 of these also had blood biochemistry at both points. Using generalized estimating equations, we examined associations with cardiometabolic risk factors. Models incorporated …

Fifty participants were assessed at 12 years, …

Infant Feeding Practices Of Emirati Women In The Rapidly Developing City Of Abu Dhabi, United Arab Emirates, Hazel Gardner, Katherine Green, Andrew Gardner

Research outputs 2014 to 2021

Rapid economic and cultural transition in the United Arab Emirates (UAE) has been accompanied by new challenges to public health; most notably a rapid rise in chronic disease. Breastfeeding is known to improve health outcomes in adulthood, is associated with reduced risk of developing chronic disease, and is therefore an important public health issue for this rapidly increasing population. Factors associated with infant feeding practices were examined in a cohort of 125 Emirati women and their infants, with data collected at birth and 3, 6 and 15 months postpartum by questionnaires and interviews. Participants were recruited in the Corniche Hospital, …

Evaluation Of A Mobile Phone Image-Based Dietary Assessment Method In Adults With Type 2 Diabetes, Megan E. Rollo, Susan Ash, Philipa Lyons-Wall, Anthony W. Russell

Research outputs 2014 to 2021

Image-based dietary records have limited evidence evaluating their performance and use among adults with a chronic disease. This study evaluated the performance of a 3-day mobile phone image-based dietary record, the Nutricam Dietary Assessment Method (NuDAM), in adults with type 2 diabetes mellitus (T2DM). Criterion validity was determined by comparing energy intake (EI) with total energy expenditure (TEE) measured by the doubly-labelled water technique. Relative validity was established by comparison to a weighed food record (WFR). Inter-rater reliability was assessed by comparing estimates of intake from three dietitians. Ten adults (6 males, age: 61.2 ± 6.9 years old, BMI: 31.0 …

Evaluation Of A Modified Food Frequency Questionnaire To Measure Lignans In Australian Men And Women, Ying Qi Winnie Li

Theses: Doctorates and Masters

Phytoestrogens are plant compounds that possess estrogenic and biological properties that have been postulated to protect against chronic diseases. Isoflavonoids and lignans are two main classes of phytoestrogen that have been investigated for their estrogenic efficacy and occurrence in the human diet. Isoflavonoids are found in soy and related products, whereas lignans are found in a wider range of plant-based foods, such as cereals, vegetables, fruits, legumes, nuts and seeds; and in beverages such as tea, coffee and wine. In Western populations with low dietary intake of soy products, compared to the Asian counterparts, lignans could be a more important …

Higher Breakfast Glycaemic Load Is Associated With Increased Metabolic Syndrome Risk, Including Lower Hdl-Cholesterol Concentrations And Increased Tag Concentrations, In Adolescent Girls, Analise Nicholl, Mary Du Heaume, Trevor A. Mori, Lawrence J. Beilin, Wendy H. Oddy, Alexandra P. Bremner, Therese A. O'Sullivan

Research outputs 2014 to 2021

Almost all previous studies examining the associations between glycaemic load (GL) and metabolic syndrome risk have used a daily GL value. The daily value does not distinguish between peaks of GL intake over the day, which may be more closely associated with the risk of the metabolic syndrome. The aim of the present study was to investigate the cross-sectional associations between daily and mealtime measures of GL and metabolic syndrome risk, including metabolic syndrome components, in adolescents. Adolescents participating in the 14-year follow-up of the Western Australian Pregnancy Cohort (Raine) Study completed 3 d food records and metabolic assessments. Breakfast …

Research outputs 2014 to 2021

Despite the increasing use of dietary patterns (DP) to study diet and health outcomes, relatively few studies have examined the reliability of DP using different dietary assessment methods. Reduced-rank regression (RRR) is an emerging statistical method that incorporates a priori information to characterise DP related to specific outcomes of interest. The aim of the present study was to compare DP identified using the RRR method in a FFQ with those in a 3 d food record (FR). Participants were 783 adolescents from the Western Australian Pregnancy (Raine) Cohort Study who completed both a FFQ and FR at 14 years of …

Impact Of Nutrition On Cognition And Its Association With Blood And Brain Alzheimer Disease Related Biomarkers, Samantha Gardener

Theses: Doctorates and Masters

Alzheimer’s disease (AD), the most common form of senile dementia, currently affects over 35 million people worldwide. While there is no cure or effective treatment, early intervention programs hold considerable promise. Following particular dietary patterns represents one potential intervention strategy accessible to all.

Results from previous studies investigating the association of diet, cognition and biomarkers of AD are inconsistent: Positive results have been reported (1-7), whilst others have shown no associations. Prior to this thesis, no study has assessed the relationship of four dietary patterns to cognition, blood-based and neuroimaging biomarkers of AD in a large highly-characterised ageing cohort. Participants …
