Walnuts And Dietary Approaches To The Prevention And Management Of Abnormal Lipid Profiles In Type 2 Diabetes Mellitus, Linda C. Tapsell, L. J. Gillen, C. S. Patch
Walnuts And Dietary Approaches To The Prevention And Management Of Abnormal Lipid Profiles In Type 2 Diabetes Mellitus, Linda C. Tapsell, L. J. Gillen, C. S. Patch
L. C. Tapsell
Dietary fat is considered central to the management of obesity and heart disease risk, and more recently with the risk of type 2 diabetes, given its observed role in the development of insulin resistance in mechanistic studies. For changes in lipid profiles, foods delivering substantial amounts of polyunsaturated fatty acids relative to saturated fats are of interest, and walnuts fit this category.As a class of foods, nuts have been shown to provide benefits to health in a number of clinical trials. A review of the cardiovascular benefits of nuts indicated their value on thrombotic factors, inflammatory markers and endothelial function.Including …

Low Plasma Vitamin E Levels In Major Depression: Diet Or Disease?, A. J. Owen, Marijka Batterham, Y. C. Probst, Brin F. Grenyer, Linda C. Tapsell
L. C. Tapsell
"Objective: Levels of vitamin E have been reported to be lower in patients suffering major depression, but whether this is due to inadequate dietary intake or the pathophysiology of depression is not known, and was the subject of the present study. Setting: Wollongong, Australia. Methods: Plasma vitamin E (a-tocopherol) was measured in 49 adults with major depression, age (mean7s.d.): 47712 y. In a subset (n¼19) usual dietary intake of vitamin E was determined by diet history. Results: Subjects had significantly lower plasma a-tocopherol (4.7170.13 mmol/mmol cholesterol) than has previously been reported for healthy Australians, and plasma a-tocopherol was inversely related …
Diet And Metabolic Syndrome: Where Does Resistant Starch Fit In?, Linda C. Tapsell
Diet And Metabolic Syndrome: Where Does Resistant Starch Fit In?, Linda C. Tapsell
L. C. Tapsell
Metabolic syndrome is a term linking the clinical profiles of some of the world’s major health problems today: obesity, heart disease and diabetes. It is predicated on dietary patterns, and particularly on the delivery of fuel. The effects may be seen first in the development of abdominal obesity and insulin resistance leading to type 2 diabetes mellitus and coronary heart disease. This review examines the role resistant starch might play in the prevention and management of these conditions. Beginning with a definition of resistant starch, a critical review of the scientific literature is presented. Current knowledge suggests that resistant starch …
Reviewing The Meanings Of Wellbeing And Wellness And Their Implications For Food Choice, Anne Mcmahon, Peter Williams, Linda C. Tapsell
Reviewing The Meanings Of Wellbeing And Wellness And Their Implications For Food Choice, Anne Mcmahon, Peter Williams, Linda C. Tapsell
L. C. Tapsell
Wellness and wellbeing are terms found in a broad range of literature such as economics, social science, food marketing and general social commentary. These terms are often used in contexts which encompass mental, physical and emotional health as well as broader more esoteric aspects of life satisfaction such as happiness. The terms wellness and wellbeing are also used ubiquitously and variably in health practice. However, there is limited understanding about the terms’ use in the broader health promotion context and how consumers might interpret these terms in the context of food and nutrition messages. The primary aim of this paper …

Genetic Adult Lactase Persistence Is Associated With Risk Of Crohn's Disease In A New Zealand Population, Deborah Nolan, Dug Yeo Han, Wen Jiun Lam, Angharad R. Morgan, Alan G. Fraser, Linda C. Tapsell, Lynnette R. Ferguson
L. C. Tapsell
Background Mycobacterium avium subspecies paratuberculosis (MAP) is an infective agent found in ruminants and milk products, which has been suggested to increase the risk of gastrointestinal inflammation in genetically susceptible hosts. It is hypothesized that lactase persistence facilitates exposure to such milk products increasing the likelihood of adverse outcomes. Individuals either homozygous or heterozygous for the T allele of DNA variant, rs4988235, located 14kb upstream from the LCT locus, are associated with having lactase persistence. The aim of this study was to determine whether lactase persistence as evident by the T allele of rs4988235 is associated with Crohn’s Disease (CD) …

Relationship Between Plantar Pressures, Physical Activity And Sedentariness Among Preschool Children, Karen J. Mickle, Dylan P. Cliff, Bridget J. Munro, Anthony D. Okely, Julie R. Steele
Relationship Between Plantar Pressures, Physical Activity And Sedentariness Among Preschool Children, Karen J. Mickle, Dylan P. Cliff, Bridget J. Munro, Anthony D. Okely, Julie R. Steele
A. D. Okely
It has been speculated that high plantar pressures might cause foot pain and discomfort which, in turn, may discourage children from being physically active and result in them spending more time in sedentary activities. The purpose of this study was to determine whether plantar pressure distributions generated by preschool children were correlated with objectively measured time spent in physical activity and sedentary behaviour. Dynamic plantar pressures were measured for 33 preschool children (age = 4.3±0.6 years; height = 1.06±0.1 m; mass = 18.4±2.9 kg; 17 boys) as they walked across an emed AT-4 pressure platform. Physical activity was objectively assessed …

What Is The Effect Of A Physical Activity Program On Foot Structure & Function In Overweight & Obese Children?, D. L. Riddiford-Harland, J. R. Steele, L. A. Baur, Dylan P. Cliff, Anthony D. Okely, P. J. Morgan, R. A. Jones
A. D. Okely
It has been speculated that the higher peak pressures typically generated beneath the feet of overweight/obese children may result in excessive discomfort of these children’s developing feet (Mickle et al. 2006, Dowling et al. 2001), in turn, acting as a deterrent to them participating in physical activity. Apart from perpetuating the cycle of obesity via decreased energy expenditure, physical inactivity in young children can restrict opportunities for these children to develop basic motor skills and, possibly, proper musculoskeletal development. We postulated that an intervention designed to improve fundamental movement skill (FMS) performance in overweight and obese young children may influence …

Don C. Iverson
Background Evidence is growing on the benefit of physical activity to improve well-being following a cancer diagnosis. This study examined changes in physical activity from pre to post diagnosis and explored this relationship with quality of life and depression. Methods Participants were recruited by posters and by letter of invitation. The questionnaire was completed by 59 prostate and 32 breast cancer survivors. Results Physical activity decreased by 72 minutes per week from pre to post diagnosis, although 20.9% reported having increased activity post diagnosis. Over 30% were considered depressed. Breast cancer participants who increased physical activity post diagnosis reported higher …
Is Sleep Duration Associated With Obesity In Older Australian Adults?, Christopher A. Magee, Peter Caputi, Don C. Iverson
Is Sleep Duration Associated With Obesity In Older Australian Adults?, Christopher A. Magee, Peter Caputi, Don C. Iverson
Don C. Iverson
Objectives: To investigate the relationship between sleep duration and obesity in older Australian adults. Method: Self-reported health data were collected through the 45 and Up Study. Multinomial logistic regression models were used to test the relationship between sleep duration and body mass index, controlling for a range of demographic and health-related variables. Results: The sample included 45,325 Australian adults aged 55 to 95 years. The regression models demonstrated that short and long sleep were associated with obesity in 55- to 64-year-olds but not in those aged 65 years and above. Discussion: The present results suggest that the relationships between sleep …

A Study Of Headache In North American Primary Care: Report For The Ambulatory Sentinel Practice Network, L A. Becker, Donald C. Iverson, F M. Read, N Calogne, R S. Miller, W L. Freeman
Don C. Iverson
Headache is a common symptom in primary care about which surprisingly little is known. Over a 14-month period 3847 patients making 4940 consecutive visits for headache to 38 primary care practices in the USA and Canada were studied. The clinical characteristics of patients, as well as the diagnostic and therapeutic strategies employed by their doctors, were examined. Visits for headache represented 1.5% of all visits during this period. Most patients (72.0%) made only one visit, and nearly half of the headaches reported were new. Only a small number of patients (3.0%) received a computerized tomographic scan; other investigations were used …
Occupational Factors And Sick Leave In Australian Employees, Christopher Magee, Natalie Stefanic, Peter Caputi, Don Iverson
Occupational Factors And Sick Leave In Australian Employees, Christopher Magee, Natalie Stefanic, Peter Caputi, Don Iverson
Don C. Iverson
Objectives: To investigate occupational factors associated with sick leave over a 4-year period in Australian employees. Methods: Longitudinal data (self-report) from 2861 Australian full-time employees (69.4% male) were used. Occupational factors and relevant covariates were assessed at baseline with sick leave assessed yearly over a 4-year period. The data were analyzed using multinomial logistic regression models. Results: Job strain and longer commuting time were associated with long sick leave, whereas long work hours were inversely associated with long sick leave. Conclusions: These results provide further evidence that certain aspects of work are associated with sick leave, whereas other work aspects …
Sleep Duration And Obesity In Middle-Aged Australian Adults, Christopher A. Magee, Donald C. Iverson, Peter Caputi
Sleep Duration And Obesity In Middle-Aged Australian Adults, Christopher A. Magee, Donald C. Iverson, Peter Caputi
Don C. Iverson
The present study examined the association between sleep duration and obesity in 40,834 middle-aged Australian adults. Multinomial logistic regression was used to test the relationship between sleep duration and obesity while controlling for important demographic and health covariates; separate models were tested for males and females. Short sleep (i.e., <7 h a night) was found to be independently associated with obesity in males and females. To our knowledge, this is the first study to report an association between short sleep and obesity in Australian adults. Although more research is required, interventions targeting short sleep could aid obesity treatment and prevention.

Using Interviews And Peer Pairs To Better Understand How School Environments Affect Young Children's Playground Physical Activity Levels: A Qualitative Study, Anne-Maree Parrish, Heather Yeatman, Donald Iverson, Ken Russell
Don C. Iverson
School break times provide a daily opportunity for children to be active; however, research indicates this time is underutilized. Reasons for low children’s playground activity levels have primarily focused on physical barriers. This research aimed to contribute to physical environmental findings affecting children’s playground physical activity levels by identifying additional variables through the interview process. Thirteen public schools were included in the sample (total 2946 children). Physical activity and environmental data were collected over 3 days. Environmental variables were manually assessed at each of the 13 schools. Observational data were used to determine which three schools were the most and …

The Older Patient, The Doctor And The Trainee: Patients' Attitudes And Implications For Models Of Care, Andrew Bonney, Sandra Jones, Donald Iverson
Don C. Iverson
Aims & rationale/Objectives Population ageing poses major challenges for health systems. Additionally, training future general practitioners in the management of older and chronically ill patients is potentially hampered by the reluctance of these patients to consult trainees for chronic care. This paper reports a cross-sectional study investigating the attitudes of older patients to trainees, to inform strategies to improve older patient-trainee interaction. Methods The survey instrument was distributed to 1900 patients aged 60 and over from 38 training practices from five Australian states using a stratified, randomised cluster sampling process. Generalised estimating equation models were used for analysis. Principal findings …
Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi
Examining The Pathways Linking Chronic Sleep Restriction To Obesity, Christopher A. Magee, Xu-Feng Huang, Donald C. Iverson, Peter Caputi
Don C. Iverson
A growing number of studies have identified chronic sleep restriction as a potential risk factor for obesity. This could have important implications for how obesity is prevented and managed, but current understanding of the processes linking chronic sleep restriction to obesity is incomplete. In this paper, we examined some of the pathways that could underlie the relationship between chronic sleep restriction and obesity. This involved exploring some of the potential environmental, health, behavioral, and sociodemographic determinants of chronic sleep restriction, which require further investigation in this context. Three pathways that could potentially link chronic sleep restriction to obesity were then …
Australian Adolescents' Compliance With Sun Protection Behaviours During Summer: The Importance Of The School Context, Melinda Williams, Sandra C. Jones, Peter Caputi, Donald Iverson
Australian Adolescents' Compliance With Sun Protection Behaviours During Summer: The Importance Of The School Context, Melinda Williams, Sandra C. Jones, Peter Caputi, Donald Iverson
Don C. Iverson
Adolescents exhibit significantly lower sun protection behaviours than adults in Australia. While many studies have assessed the sun protection behaviours of adolescents during summer, few studies have explored the differences in sun protection behaviours of adolescents across key contexts relevant to adolescents during summer—notably school time, weekends and school holidays. Greater understanding of differences in behaviours across these contexts provides more detailed explanations of the nature of adolescent ultraviolet exposure and thereby facilitates improved targeting of interventions for this segment whose behaviour is considered hard to change. In this study, we explore the differences in self-reported, habitual, sun protection behaviours …
Australian Women's Perceptions Of Breast Cancer Risk Factors And The Risk Of Developing Breast Cancer, Sandra C. Jones, Christopher A. Magee, Lance R. Barrie, Donald C. Iverson, Parri Gregory, Emma L. Hanks, Anne E. Nelson, Caroline L. Nehill, Helen M. Zorbas

Don C. Iverson
Background Numerous studies have shown that the majority of women overestimate both their own risk and the populations’ risk of developing breast cancer. A number of factors have been found to correlate with perceived risk. Methods This paper reports on a telephone survey of a nationally representative sample of approximately 3,000 Australian women aged 30 to 69 years, conducted in 2007, and compares the findings with those of a similar survey conducted in 2003. Results There was a clear tendency for respondents to overestimate the proportion of women who will develop breast cancer during their lifetime. Approximately half the respondents …

General Practice Registrars: Attitudes Of Older Patients, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson
Don C. Iverson
Previous research indicates that older patients may be less willing to consult general practice registrars (GPRs), reducing training opportunities in chronic/complex care. This survey explores older patients’ attitudes in order to inform models of interaction that would be acceptable to patients. METHODS Ten training general practices distributed questionnaires for self completion to 50 patients aged 60 years and over. Chi-square, Spearman’s rho and logistic regression were used for analysis. RESULTS The response rate was 47%. Ninetysix percent wanted ongoing contact with their general practitioner if they saw a GPR. Twenty-four percent were comfortable with GPR chronic/complex care, increasing to 73% …

Objective: To examine the nature of disease awareness advertising (DAA). Design: Therapeutic advertisements in six popular Australian women’s magazines were monitored between April 2006 and March 2007. A subset of advertisements was included in the study based on criteria derived from a definition of DAA. Unique advertisements were analysed by four independent coders. Main outcome measures: Types of advertisements and their sponsors, the types of disease information present, and the persuasive techniques utilised. Results: Of 711 advertisements identified, 60 met the inclusion criteria for DAA, and 30 of these were unique. Over one-third of the advertisements were classified as “unbranded …
Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson
Preparing For An Ageing Population: A Survey Of Older Patients' Attitudes To General Practice Registrars, Andrew D. Bonney, Sandra C. Jones, Lyn Phillipson, Donald C. Iverson
Don C. Iverson
The ageing population makes it imperative to provide appropriate training for general practice registrars (GPRs) in the community-based care of older patients. However, data suggest that older patients may be less willing to consult GPRs for chronic/complex care; adversely affecting training opportunities and potentially the satisfaction of older patients in training practices. This cross-sectional study was undertaken to investigate this concern in the Australian context and develop models of older patient-GPR interaction that are acceptable to patients.
