Summary
Women with gestational diabetes (GDM) whose blood glucose levels (BGL) are not well controlled have a higher chance of giving birth to large babies. These babies are at high risk of becoming overweight children and adults. Preventing child obesity therefore requires appropriate intervention during pregnancy complicated with GDM. This study will determine the ability of specific dietary advice (aimed at reducing maternal BGL) to reduce the risk of large babies in a typical ante-natal setting.
This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrat ....This proposal is designed to test the protein leverage hypothesis (PLH) in humans: the idea that the level of food consumption in humans, like other animals, is adjusted to maintain a target protein intake. As the prevalence of overweight and obesity increases, with its attendant health problems, the need to identify which dietary components limit rather than exacerbate energy intake is imperative. According to the PLH, the consumption of a diet low in % protein and high in % fat and carbohydrate, typical of many Western countries, inevitably requires the ingestion of additional energy to maintain protein intake constant, thus driving weight gain. Conversely, the consumption of a diet that is relatively high in % protein requires the ingestion of lower levels of energy, creating the potential for weight loss. Preliminary experimental and population-level nutritional survey data support the PLH, as does the finding that protein is more satiating than other macronutrients. If, as predicted, small changes in the proportion of protein in diets described in the current study are found to impact on total energy intake there will be significant implications for weight control strategies. Thus, if the PLH is confirmed, public health dietary recommendations and government policy settings for the food industry will need to change. Large-scale intervention studies aimed at demonstrating the longer term impact on body weight will also be required.Read moreRead less
An RCT To Promote Healthy Lifestyle Behaviours From Infancy: An Intervention To Prevent Childhood Overweight

Summary
In Australia, one in four school-aged children is currently overweight and childhood obesity rates are continuing to rise. In the last five years it has become clear that rates of overweight and obesity are also rapidly increasing in pre-school age children. These are issues that are of concern to health officials as well as to parents. We understand that these rising rates in fatness relate to children's diet and activity patterns, and that these patterns, once established are likely to be patt ....In Australia, one in four school-aged children is currently overweight and childhood obesity rates are continuing to rise. In the last five years it has become clear that rates of overweight and obesity are also rapidly increasing in pre-school age children. These are issues that are of concern to health officials as well as to parents. We understand that these rising rates in fatness relate to children's diet and activity patterns, and that these patterns, once established are likely to be patterns for life. To date, there has been relatively little research regarding the chance to support parents to establish the eating and activity patterns that will protect their children from the very beginning of life. This project seeks to support first-time parents to establish healthy eating and activity behaviours in their children using the highly utilised Maternal and Child Health Centres first time parents' groups. We believe that these groups will provide a strongly supportive environment in which to provide parents with strategies and knowledge for promoting healthy eating and activity patterns for their children, and in turn, promote healthy weight gain. This project will assess the effectiveness of this intervention.Read moreRead less
Reducing The Mortality Gap For People With Schizophrenia

Funding Amount
$1,231,125.00
Summary
People with schizophrenia die >16 years earlier than the general population, mostly due to avoidable diseases such as diabetes and heart disease. This research aims to conduct clinical trials among people with schizophrenia of 1. an existing diabetes medication (metformin) to prevent initial weight gain due to antipsychotic medications and 2. a novel diabetes medication (exenatide) to help people who don’t have adequate weight loss with metformin.
A Vision Of Healthy Urban Design For NCD Prevention

Summary
We are living in a new city era with new risks for health, and new ways to understand them. This project will combine state-of-the art methods in computer vision and artificial intelligence alongside co-creation of a web-based toolkit for action for use by city planners and urban designers that demonstrate practical pathways Improving our understanding of the strengths and limitations of existing city designs to ensure they are safe, clean, healthy, and sustainable.
Does Obesity Have The Characteristics Of Addiction?
Funder
National Health and Medical Research Council
Funding Amount
$430,832.00
Summary
The number of overweight or obese people in Australia has increased dramatically in recent years, increasing disease risk. The brain responds to palatable food in ways similar to the response to drugs of addiction, and this may explain why people find it hard to resist palatable food. Our work will explore whether obesity in rats has the characteristics of addiction by examining bingeing, craving, withdrawal and brain circuits in animals chronically exposed to palatable food.
Birth Weight, Adult Weight And Podocyte Depletion.

Funding Amount
$796,252.00
Summary
A major role of our kidneys is to filter our blood. A key cell type in our kidney filters is an octopus-shaped cell known as the podocyte. If we are not born with enough podocytes, or if the filters grow too large after birth due for example to excessive weight gain, the podocytes cannot adequately filter the blood, and this can lead to kidney disease. We will measure podocyte endowment at birth, and assess the effects of weight gain and loss after birth on podocyte features and kidney health.
Signaling Pathways To Enhance Potency Of AMPK-targeting Drugs

Funding Amount
$661,966.00
Summary
Sedentary lifestyles and consumption of high energy foods has led to epidemics of obesity-related metabolic diseases that place enormous financial and medical burden on the Australian economy. An attractive drug target to treat these diseases is AMP-activated protein kinase (AMPK) which functions as both a cellular fuel gauge and co-ordinator of whole-body metabolism. Our goal is to improve AMPK drug potency by identifying novel processes that sensitize AMPK to drugs.
S100A8/A9 As A Target In Metabolic Diseases To Inhibit The Acceleration Of Cardiovascular Disease

Funding Amount
$554,990.00
Summary
Obesity and diabetes are the leading cause of premature death, due to accelerated cardiovascular disease (CVD). The abundance of blood monocytes influences the progression and regression of CVD. We discovered that S100A8/A9 promotes monocyte production in obesity and diabetes. This project will explore how S100A8/A9 is produced in diabetes and obesity and if blocking its function using a novel drug will prevent obesity and diabetes associated CVD.
Regulatory Strategies To Promote Healthier Australian Diets

Funding Amount

Summary
Unhealthy diets are a leading cause of ill health. In contrast to our global leadership in tobacco control, Australia remains slow to use law as a tool to support healthy eating. This project will generate new insights on features of effective food policies to target excess sugar consumption. Using an innovative fusion of law and science, its findings will inform and accelerate current proposals to improve food labelling and tax sugary drinks to promote healthier Australian diets.
