Short And Long Sleep Duration Are Associated With Prevalent Cardiovascular Disease In Australian Adults, Christopher A. Magee, Len Kritharides, John Attia, Patrick Mcelduff, Emily Banks

Faculty of Health and Behavioural Sciences - Papers (Archive)

A growing number of studies from a range of different countries have observed an association between sleep duration and cardiovascular disease. The objective of this paper was to examine the associations between sleep duration and prevalent cardiovascular disease in a large sample of Australian adults, and identify the sociodemographic and health-related factors moderating these associations. Participants included 218 155 Australian adults aged 45 years and over. The results indicated that 6 h versus 7 h sleep was associated with increased odds of heart disease [odds ratio (OR) = 1.11 (1.06–1.17)], diabetes [OR = 1.15 (1.09–1.22)], stroke [OR = 1.25 (1.14–1.38)] …

Dementia, Stigma And Intentions To Help-Seek: A Pilot Study Of Australian Adults 40 To 65 Years, Lyn Phillipson, C Magee, Sandra C. Jones, S Reis, E Skladzien

Faculty of Health and Behavioural Sciences - Papers (Archive)

Stigma (prejudice or negative stereotypes associated with personal attributes such the presence of ill health or disease) is an important concept as it has the potential to adversely impact on social exclusion, help seeking behaviours and the utilisation of health and social services. Whilst limited international research suggests that there may be stigma associated with dementia, this paper presents results from the first comprehensive study to explore stigma towards dementia in Australia. Results from an online survey of Australian adults (45-60 years) outline the nature and presence of negative attitudes or stereotypes towards dementia and people living with dementia, and …

Effects Of A Single Dose Of Exenatide On Appetite, Gut Hormones, And Glucose Homeostasis In Adults With Prader-Willi Syndrome, Lisa Sze, Louise Purtell, Arthur Jenkins, Georgina Loughnan, Ellie Smith, Herbert Herzog, Amanda Sainsbury, Katharine Steinbeck, Lesley V. Campbell, Alexander Viardot

Faculty of Health and Behavioural Sciences - Papers (Archive)

Context: Prader-Willi syndrome (PWS) is associated with hyperphagia and obesity, without effective pharmacological treatment. Exenatide, recently developed for treatment of type 2 diabetes, induces appetite suppression and weight loss with common side effects. Objective: The objective of the study was to investigate the initial safety and effectiveness of exenatide in adult PWS subjects compared with obese controls (OBESE). Design, Setting, Patients, and Intervention: Eight PWS and 11 OBESE patients underwent standardized meal studies after a single sc injection of 10 g exenatide or placebo in a single-blinded, crossover design. Main Outcome Measures: Glucose, insulin, C-peptide, glucagon, peptide YY (PYY; total)/PYY …

Big Five Personality Factors, Obesity And 2-Year Weight Gain In Australian Adults, Christopher A. Magee, Patrick C. L Heaven

Faculty of Health and Behavioural Sciences - Papers (Archive)

The objective of this paper was to examine whether the Big-Five Personality factors were associated with obesity and 2-year weight gain in Australian adults. The sample included 5265 Australian adults aged 25– 65 years. Binary logistic regression models indicated that Extraversion, Agreeableness and Neuroticism were cross-sectionally associated with obesity, with Conscientiousness inversely associated with obesity. The longitudinal analyses indicated that Extraversion predicted 2-year weight gain. The relationships between personality and obesity/weight gain were not moderated by age or sex. These results have potentially important implications for developing more effective treatment and prevention strategies for obesity.

Increased Intake Of Dietary Polyunsaturated Fat Does Not Promote Whole Body Or Preferential Abdominal Fat Mass Loss In Overweight Adults, Sze-Yen Tan, Marijka Batterham, Linda Tapsell

Faculty of Health and Behavioural Sciences - Papers (Archive)

Objective: There is evidence that increasing the proportion of polyunsaturated fatty acids (PUFA) in a diet can enhance the rate of fat oxidation acutely. Higher PUFA in a diet has also been associated with greater abdominal fat loss in longer term studies. This study aimed to investigate if higher PUFA intake would result in greater fat mass loss over a 12-week period, mainly from the abdominal region.

Methods: Data at the 12-week time point from two weight loss studies, both comparing high PUFA versus low PUFA diets was, accessed for 141 overweight subjects from the same area. Specifically, data on …

The Use Of Female Sexuality In Australian Alcohol Advertising: Public Policy Implications Of Young Adults' Reactions To Stereotypes, Sandra C. Jones, Amanda Reid

Faculty of Health and Behavioural Sciences - Papers (Archive)

Coinciding with the rise of raunch culture, a new female stereotype has emerged in advertising - the lusty, busty exhibitionist who exudes sexual power and confidence. Previous research has generally found that women react less positively to female sexual images in alcohol advertising than males, but different sexual stereotypes have not been explicitly examined. The present study utilizes different types of sexual appeals in three televised advertisements for alcohol brands and investigates the relationship between types of sexual imagery and attitude to the advertisement, stated reasons for (dis)liking the advertisement and purchase intention (PI) among 268 Australian university students. Surprisingly, …

Sleep Duration And Obesity In Middle-Aged Australian Adults, Christopher A. Magee, Donald C. Iverson, Peter Caputi

Faculty of Health and Behavioural Sciences - Papers (Archive)

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.

Is Sleep Duration Associated With Obesity In Older Australian Adults?, Christopher A. Magee, Peter Caputi, Don C. Iverson

Faculty of Health and Behavioural Sciences - Papers (Archive)

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 …

Ventilation Patterns In Red Kangaroos (Macropus Rufus Desmarest): Juveniles Work Harder Than Adults At Thermal Extremes, But Extract More Oxygen Per Breath At Thermoneutrality, Adam J. Munn, Terence J. Dawson, Shane K. Maloney

Faculty of Science - Papers (Archive)

Juvenile mortalities in large mammals are usually associated with environmental extremes, but the basis for this vulnerability is often unclear. Because of their high surface area to volume ratio, juveniles are expected to suffer greater thermal stresses relative to adults. Coping with thermal stress requires the ventilatory system to accommodate increases in oxygen demand and respiratory water loss at thermal extremes. Because juveniles are smaller than adults, these demands may set up different constraints on their ventilatory system. Using red kangaroos (Macropus rufus Desmarest), an arid zone species, we compared the ventilatory capabilities of juveniles and adults at thermoneutral (25 …
