Whither preventive health – the legacy of ANPHA (The Australian National Preventive Health Agency)

Wednesday 20 August 11:00–12:30 pm

The Australian National Preventive Health Agency (ANPHA) was a statutory authority established in 2011. ANPHA’s mission was to “be the catalyst for strategic partnerships, including the provision of technical advice and assistance to all levels of government and in all sectors, to promote health and reduce health risk and inequalities, and to initiate actions to promote health across the entire Australian community”.

The Agency’s key program areas included:
- Overweight and obesity prevention
- Tobacco control
- Harmful alcohol use
- Prevention in Medicare Locals
- National Preventive Health Awards
- Smoking & Disadvantage Network

In June this year the essential functions of ANPHA were transferred to the Department of Health. This seminar discusses the legacy of ANPHA in preventive health – its achievements during 2011–2014 and the challenges for preventive health since the Agency was closed.

SPEAKERS
Prof. Ian Caterson, Director, The Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders and Acting Director, Charles Perkins Centre Clinical Research Facility
Prof. Steve Simpson, Academic Director, Charles Perkins Centre
Prof. Adrian Bauman, Director, Prevention Research Collaboration
Prof. Stephen Leeder, Emeritus Professor of Public Health and Community Medicine

Ms. Louise Sylvan, CEO of ANPHA, will speak on “Reflections on ANPHA – highlights of national prevention leadership”

Birth weight and cardiovascular risk – a role for omega 3 PUFA in prevention?

Thursday 14 August 12:00–1:00 pm

Presenter: Dr Michael Skilton from the Boden Institute

Summary of talk
Birth weight is inversely associated with risk of adult cardiovascular disease, with a 10–20% lower risk per 1 kg higher birth weight. This heightened risk of cardiovascular diseases is of most relevance to people with the lowest birth weights. In particular, people born small for gestational age (birth weight below the 10th percentile for sex and gestational age) are a high risk group. Birth weight is inversely associated with systolic blood pressure, being 2 mm Hg higher per 1 kg lower birth weight, and may mechanistically link reduced birth weight with later cardiovascular disease.

There is currently no prevention strategy identified to lower blood pressure or reduce cardiovascular risk in people born small for gestational age. This lack of “reliable evidence from randomized trials about how to intervene” in people identified as being at risk of adult non-communicable diseases due to their early development, has recently been identified by the Lancet as a key priority area.
This seminar will outline the evidence linking small for gestational age with cardiovascular risk and early atherosclerosis, and our findings from four independent populations of children and adults that support the hypothesis that omega-3 fatty acid intake improves cardiovascular risk profile in people who were born small for gestational age.

About the presenter
Dr Michael Skilton is a vascular physiologist. His research focuses on non-invasive assessment of vascular health and disease, with a particular focus on the developmental origins of cardiovascular disease, obesity, nutrition, and Aboriginal and Torres Strait Islander health.

A consistent approach to analysing nutrition data from the Australian Health Survey

Thursday 24 July 9:00–4:30 pm

Presenters:
Steve Simpson, Lynne Cobiac, Tim Gill, Louise Gates, Paul Atyeo, Susan Shaw, Renee Sobolewski, Manny Noakes, Anna Rangan, Malcolm Riley, Dorothy Mackerras, Vicki Flood

Summary of talk
This full day workshop was organised by Associate Professor Tim Gill from the Boden Institute in conjunction with the Charles Perkins Centre, ABS, CSIRO and FSANZ. The workshop facilitated discussion around the handling and analysis of the nutrition data from the Australian Health Survey as well as some of the problems that have complicated analyses of large dietary intake datasets in the past.

Attendees travelled from all over the country and represented academia, government as well as food industry. The workshop succeeded in raising awareness around specific issues that arise in analysis of dietary intake data from sources such as the Australian Health Survey and created a clear consensus that we must find a mechanism that allow researchers working with this data to move forward to address these issues in a consistent manner.

It was suggested that a reference group be formed that could foster appropriate methodological research on use of dietary intake data, help formulate guidance around how to use and represent results from analyses of this data, generate training events or opportunities and keep a registry of current research projects which utilise the Australian Health Survey Australian Data. The Charles Perkins Centre and CSIRO agreed to help foster such a group and another workshop was planned in conjunction with the Nutrition Society conference in Hobart in November 2014.

Ultra-processed foods: A new concept in nutrition guidance

Thursday 3 July 12:00–1:00 pm

Presenter: Associate Professor Timothy Gill from the Boden Institute

Summary of talk
There is growing frustration in public health nutrition around the inconsistencies and mixed messages often created by nutrition classification systems and guidance which is based on nutrient content. Poor quality foods can be misrepresented as healthy by manipulating the serving size or by the addition of ingredients such as starches, water or even single nutrients to enable its composition to meet nutrient cutpoints defined within classification systems. At the same time consumers are demanding simple advice and a simplification of the food supply at a time when both the composition and nature of the food supply is becoming more complex and nutrition advice more conditional.

Recently a group of nutritionists in Brazil have proposed a nutrition classification system which grades foods solely on the level of processing. Foods with limited processing are deemed nutritionally superior to those regarded as ultra-processed - where the food is constructed from numerous ingredients to form a product which is durable, accessible, convenient, attractive, ready-to-eat or ready-to-heat. These nutritionists contend that simply advising people to construct a diet which includes more foods with limited or no processing and less ultra-processed foods results in better outcomes than the multiple existing nutrition guidance systems. Other nutritionists have condemned this approach as over-simplistic and the food industry vigorously opposes it. This talk will explore the concept of ultra-processed foods and whether it negates the need to base guidance on the fat, sugar, salt, fibre or GI content of foods.

Giving a Tick to Junk Food in Schools

Thursday 29 May 1:00–2:00 pm

Presenter: Dr Kieron Rooney from the from the Faculty of Health Sciences

About the presenter
Dr Kieron Rooney has a PhD specializing in Metabolic Biochemistry, is a Senior lecturer in Exercise Physiology and Biochemistry in the Faculty of Health Sciences at the University of Sydney and is a registered Nutritionist with the Nutrition Society of Australia (R Nutr.). For the past 15 years he has researched the impact of diet and physical activity on the regulation of fuel utilisation and storage. Kieron is not a public health expert, but rather a concerned parent with a bit of knowledge and whole lot of passion.

Summary of talk
There is an urgent need to review and update current guidelines overseeing food supply in school canteens. The National Healthy School Canteens (NHSC) project commenced in 2008 to help provide guidelines for healthier food and drink choices in Australian schools. At their core, the guidelines seek to restrict the availability of poor food choices by encouraging the preferential availability of healthy options.

This summer, however, the NHSC and associated state specific nutrition in schools strategies were exploited by food manufacturers to endorse processed junk food as school lunchbox “approved” under the guise of government regulation. As such, food manufacturers have highlighted yet another flaw in the current government approach to nutrition in schools.

In this lunchtime seminar, Kieron will present examples of the products currently marketed to children and parents as appropriate inclusions in a healthy lunchbox and discuss the greater concern for the healthy development of our next generation Australians – that these products do in fact, meet government approved guidelines.

Developmental origins of health and disease

Thursday 1 May 12:00–1:00 pm

Presenter: Dr Kyra Sim from the Charles Perkins Centre and the Boden Institute

Dr Kyra Sim is the Project & Research Officer of the University of Sydney’s Charles Perkins Centre: Preconception, Pregnancy, and Childhood Cohort Study and at the Boden Institute of Obesity, Nutrition, Exercise & Eating Disorders. Since graduating from her PhD in 2012, she has been employed part-time by both the International Diabetes Federation and as a research assistant investigating the association of cardiovascular risk factors in pregnant women and the obese.

The Preconception, Pregnancy and Childhood Cohort Study is a flagship project for the Charles Perkins Centre. This study will investigate how preconception and early pregnancy conditions impact on the pathways of disease. This will enable us to gain a greater understanding of the mechanisms occurring before and during pregnancy that contribute to the development of obesity, diabetes and cardiovascular disease, and related disorders, throughout life.

What is now clear is that genetic programming occurs in the fetus during pregnancy such that the infant carries a metabolic ‘load’ already by birth that can predispose it to diseases such as obesity, diabetes and cardiovascular disease. Of even more concern is that these epigenetic changes not only persist into adulthood but are transmitted into the next generation.

Adding to this complex situation is an increasing trend to later childbearing coupled with the rising prevalence of parental obesity. Maternal obesity is related to an increased risk of non-communicable disease in the offspring, usually presenting in adolescence and adulthood. Pre-pregnancy and gestational obesity may lead to a self-reinforcing vicious cycle of excessive weight gain and adiposity that is passed on from mother to offspring. Additionally, recent studies have reported adverse outcomes associated with an obese biological father. While the underlying mechanisms of such parental obesity-induced programming remain unclear, the hypothesis has important implications in explaining the rapid rise in obesity.

Most health initiatives have focused on obesity, diabetes and cardiovascular disease as medical conditions, concentrating on their complex biology at the levels of genes, cells and organs. These are important areas for research, but the causes and consequences of these diseases are much more complicated than biology alone. The Charles Perkins Centre takes a complex systems approach to disease states and the study will provide information about the biological, social, cultural and environmental context of the cohort.

The talk will present the progress of Charles Perkins Centre Cohort Study and discuss importance of the first 1,000 days and how they build the foundation for life.

Misconceptions about exercise and weight loss (seminar)

Thursday 3 April 12:00–1:00 pm

The presenter Dr Michelle (Shelley) Kay is from the Diabetes Prevention research team at the Boden Institute

Messages about exercise commonly claim it has “minimal or no effect on obesity or weight loss” and energy restriction is recommended as a more effective option.

Studies using DXA, CT and MRI, frequently report that exercise interventions promote fat loss and the preservation of lean tissue even when there is no weight loss. Further, visceral and intermuscular adipose tissue depots are targeted by exercise even when there is no energy deficit.

The effects of exercise, when limited to changes in body mass or BMI, obscure desirable body composition, anti-inflammatory and pro-metabolic outcomes. This should be considered in health promotion messages and interpretation of research.

Dr Shelley Kay is an exercise physiologist with research, consulting and educational perspectives on exercise prescription for chronic disease management and prevention. Shelley has held professional/clinical roles with a range of organisations including the RSL Lifecare Veterans Village (Narrabeen), the Australian Catholic University (ACU) and the University of Sydney. She has lectured in a number of topics related to exercise prescription and body composition and most recently Exercise, Health and Disease.

Preventing Type 2 Diabetes Mellitus in the 21st Century (master class)

Thursday 6 March 1:30–3:00 pm

The presenter Professor Iain Broom is Director of the Centre for Obesity Research and Epidemiology (CORE) at Robert Gordon University and Clinical Professor of Metabolic Medicine at the University of Aberdeen. He is also Medical Director of LighterLife, holds a Professorial Research Fellowship at the Rowett Research Centre and is a founding European SCOPE Fellow.

Summary of master class
Obesity and diabetes are linked, and hence the key to diabetes prevention is the management of weight. Are our current messages re the weight management in diabetes correct, or do we have to rethink our healthy eating message as the Swedes have done? Do we need a wardrobe as opposes to one suit fitting all? There is now evidence that type 2 diabetes can be put into remission, both medical (dietary) and surgical and lessons from this can be put into practice in the prevention of the disease. Discussions around these areas will be the basis of this master class.

This event was brought to you by the Centre for Obesity Management, Prevention and Research Excellence in Primary Health Care (COMPaRE-PHC) in partnership with the Boden Institute.

Environmental waist disposal (seminar)

Thursday 6 March 12:15–1:15 pm

The presenter Professor Iain Broom has been responsible, along with several UK colleagues, for the development of the Counterweight weight-management program, of which he is Chairman. Counterweight is one of the few weight-loss programs that have been successfully rolled out across a health system after research. Counterweight has over 12 years’ experience within the UK’s National Health Service and has been commissioned by over 30 primary care trusts and directly by the Scottish Government to implement Counterweight in 13 out of their 14 Health Boards as the weight management program of choice.

Seminar abstract
The obesity epidemic has not simply crept upon the human population, but has exploded as a major Public Health problem over 30 years. There have always been obesity problems throughout the age of man and obesity has been know to create health and early death problems since the time of Hippocrates. There is a strong genetic linkage to the likelihood of an individual becoming obese, but there is no way that our genetic inheritance has changed in such a short timescale. What has changed is the environment with which our genetic makeup now has to contend. Indeed obesity is probably the best example of gene-environment interaction producing disease. Within our genotype, however, there is the capacity to store fat in appropriate places for future energy transduction (subcutaneous) or as ectopic fat, an example being intra-abdominal fat the latter being seen as increasing waist circumference. The best example of this genotype-phenotype differences in fat deposition is within the comparison of Caucasians and Asians, the latter being more prone to deposit excess accumulation of fat in ectopic areas than the former.

It is therefore essential that we look at the changes that have occurred within our environment since the 1970's when the obesity explosion really started and examine ways by which we can mitigate these environmental effects to reduce our waist size or in effect to "increase WAIST disposal". We must, however, remember that waist circumference is only a surrogate for intra-abdominal fat and that other factors must be considered when assessing the overall risk of concomitant cardio metabolic disease in the obese. Failure to do so will result in inappropriate expenditure on targeting low risk individuals.

This event was brought to you by the Centre for Obesity Management, Prevention and Research Excellence in Primary Health Care (COMPaRE-PHC) in partnership with the Boden Institute.

Circadian drivers of poor mental and physical health

Thursday 27 February 12:00–1:00 pm

The presenter Professor Ian Hickie was appointed as the inaugural executive director of the flagship Brain & Mind Research Institute at the University of Sydney in 2003. Since then he has overseen its development as a major hub in translational neuroscience and clinical psychiatry.

The Brain & Mind Sciences is one of the most fascinating areas of medical research. At its centre is improving our understanding of the nature of our most human experiences – emotion, affection, cognition and social relationships. When things go wrong, we see the most devastating effects on a person’s quality of life.

Improving our treatments, and making sure that people can access to those interventions, lie at the heart of Professor Ian Hickie's work. There is no doubt that the Brain & Mind Sciences will be at the centre of major breakthroughs in the 21st century. The impacts of such advances will go well beyond the treatment of illness to impact on broader issues such as child development, educational practices, workplace transformations and community development.

Behavioural weight management interventions in primary care

Thursday 6 February 12:00–1:00 pm

The presenter Ms Claire Madigan is a final year doctoral student at the University of Birmingham, England. After her study visit to Australia she will be working as a research fellow on a randomised controlled trial, examining the effect of self-weighing for weight maintenance. Her research interests include investigating behavioural weight management programmes, particularly those that can be utilised in primary care.

Prior to commencing her academic career, Claire worked as a public health practitioner commissioning services related to weight management and working strategically on local weight management services for children. She has utilised these experiences in her academic work, ensuring the focus is on interventions that are effective, but can also be implemented in a healthcare setting.
