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.

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
Longitudinal Growth, Nutrition And Physical Activity In Young Children With Cerebral Palsy

Summary
Cerebral palsy is the most common type of physical disability impacting on 1 in 500 children, with lifetime costs of $2m and up to 40% may have restricted growth and nutrition. We aim to follow a cohort of 240 young children with Cerebral Palsy from 18 mths to 5 years to monitor their growth, nutrition, habitual activity, body composition and relate this to comprehensive health outcomes and costs. Better knowledge of these factors will enable nutritional and medical care to be better focused.

Summary
Children who are obese have a higher risk of numerous health problems, including high blood pressure, high cholesterol and joint problems. They also experience reduced self-esteem and discrimination as well as an increased risk of premature death or poor health due to heart disease and Type 2 diabetes in adulthood. Approximately 25% of Australian children are overweight or obese. This prevalence has doubled since the 1980's and is still increasing.

They also experience reduced self-esteem and discrimination as well as an increased risk of premature death or poor health due to heart disease and Type 2 diabetes in adulthood. Approximately 25% of Australian children are overweight or obese. This prevalence has doubled since the 1980's and is still increasing. Child obesity is a major public health problem and innovative approaches to solving this problem are urgently needed. A range of factors has been postulated as contributing to the global childhood obesity epidemic, including environmental, psychosocial, physical, nutrition, metabolic and lifestyle factors. However, the major determinants involve a shift away from energy balance through reduced energy expenditure or physical activity and increased energy intake. Conventional weight-management strategies have incorporated restricting energy intake or diet, increasing energy expenditure or physical activity, decreasing sedentary activities, parental involvement, and behaviour modification. However, these strategies have only shown moderate success among children in the medium to long term and very few can be translated into community settings. The purpose of this study, and its original contribution to research, is to determine the impact of a physical activity skill development and parent-centred family weight management program on the weight, cardiovascular health, physical activity, dietary intake, and sedentary behaviours of overweight and obese children.Read moreRead less

Summary
Cardiovascular disease is the major source of death in developed countries. In Australia it accounts for more deaths than cancer and is associated with considerable economic cost. The use of antioxidant vitamin supplements for reduction of heart disease risk is now discouraged because several large studies with vitamin E (containing one form of vitamin E called alpha-tocopherol) have shown no benefit.

In Australia it accounts for more deaths than cancer and is associated with considerable economic cost. The use of antioxidant vitamin supplements for reduction of heart disease risk is now discouraged because several large studies with vitamin E (containing one form of vitamin E called alpha-tocopherol) have shown no benefit. However, there remains a major discrepancy between intervention studies using pure alpha-tocopherol and population studies showing a benefit of diet derived antioxidants. We believe that this project will help clarify this discrepancy and provide data which may provide evidence for functional foods enriched with another form of vitamin E called gamma-tocopherol. Gamma-tocopherol is common in some foods and it may have different properties compared to alpha-tocopherol. We have already established that supplementation for six weeks with gamma-tocopherol leads to a marked increase in blood and tissue levels of gamma-tocopherol. Dietary gamma-tocopherol has potential antiinflammatory activity. This project will study how gamma-tocopherol may work as an antiinflammatory agent which could help to protect against heart disease. The project will clarify the potential role of dietary gamma-tocopherol in cardiovascular disease and strengthen the recommendation for mixed dietary 'antioxidants' in place of pure supplements such as alpha-tocopherol.Read moreRead less
Long Term Impact, Capacity Gains And Cost-effectiveness Of A Successful Community-wide Child Obesity Prevention Program

Summary
Be Active, Eat Well is the first community-wide obesity prevention project to successfully reduce the weight and waist gain of children. The 'intervention' was to 'boost' community capacity to enable the local organisations to create their own solutions to childhood obesity. This research will continue to assess the project 3 years after that 'boost' to determine the long-term sustainability, impact and cost-effectiveness of this approach to prevent childhood obesity.
A Multicentre Randomised Clinical Trial Of Physical Activity For The Treatment Of Patients With Alzheimers Disease

Summary
The number of older adults living with Alzheimer's disease (AD) will increase from 26.6 million to 106.2 million by 2050. In the absence of curative treatment options it is important to focus on non-pharmacological interventions such as physical activity. We propose to investigate whether a home-based physical activity program of 24 weeks for patients with AD can successfully decrease the rate of cognitive and functional declince and improve quality of life and psychological well-being.

Physical inactivity ranks second only to tobacco use in terms of the costs of diseases associated with behavioural risk factors. Declining rates of physical activity have been associated with increasing rates of obesity and overweight in Australian children and adults. The association that one sees between features of the urban environment and physical activity levels suggests that urban planning guidelines may be a cost-effective means of promoting health and achieving other social objectives such as sustainable use of natural resources. Furthermore, not enough is known about the economic value of investing in health promoting interventions and this project is among the first to measure the costs and benefits of intervening at the environmental level. The information that it provides will be highly useful for local government and health service planners alike.Read moreRead less

Dementia and depression are the most frequent mental health disorders of older people. They are also the leading causes of years of life lost due to disability in Australia. The results of recent studies have shown that memory difficulties and dementia are associated with potentially modifiable risk factors, such as physical activity. The purpose of this study is to investigate whether a physical activity program for older adults decreases cognitive decline and conversion to dementia in a population at risk: mild cognitive impairment (MCI). 168 subjects with MCI will be randomised (by chance, like the flip of a coin) to either the intervention program of physical activity or usual care - their cognitive (such as memory) performance will be compared at the end of 24 months.Read moreRead less

Summary
Participation in regular moderate to vigorous intensity physical activity reduces risk for cardiovascular disease, non-insulin dependent diabetes, osteoporosis and some cancers. Recent epidemiological recommendations are that 30 minutes of moderate intensity physical activity (e.g. brisk walking at 4.8-6.4 km-hr) on most days is sufficient to confer these significant health benefits. However, many Australians spend substantial amounts of time engaged in household chores and gardening - yardwork ....Participation in regular moderate to vigorous intensity physical activity reduces risk for cardiovascular disease, non-insulin dependent diabetes, osteoporosis and some cancers. Recent epidemiological recommendations are that 30 minutes of moderate intensity physical activity (e.g. brisk walking at 4.8-6.4 km-hr) on most days is sufficient to confer these significant health benefits. However, many Australians spend substantial amounts of time engaged in household chores and gardening - yardwork activities but it is unknown whether the intensities of these activities are sufficient to confer the aforementioned health benefits. The aims of this study are therefore to: 1. Measure directly the energy cost of self-paced common household chores and gardening - yard activities. 2. Provide data that are required to estimate accurately the prevalence of 'adequate' levels of physical activity among adults. 3. Identify indirect methods (such as heart rate, motion and breathing frequency) which, in combination, are suitable for use in large scale surveys of activity levels. The outcomes of this study will be: 1. A greatly improved understanding of whether energy expenditure associated with self-paced household chores and gardening - yard activities is adequate to confer health benefits. 2. Our results will be used in key public health interventions which are aimed at modifying the physical activity levels of Australians. 3. If the public health message encourages some of the ~30% of sedentary Australians to undertake regular moderate intensity physical activity then this will: reduce the cost of the health care system, substantially reduce the premature loss of life and decrease morbidity and disability. 4. Our results will help public health epidemiologists to monitor the percentage of Australians who are adequately physically active.Read moreRead less
