Summary
There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and ....There is now no doubting the size and long-term risks to health of the childhood obesity epidemic. However, very little research has examined at population level its immediate consequences for mental health and physical functioning, what pathways confer risk and protection for these consequences, and their likely healthcare consequences. This study will utilise an existing cohort of approximately 1500 Victorian adolescents followed since childhood to examine neglected aspects of the genesis and impacts of overweight and obesity. The Health of Young Victorians Study was originally assembled in 1997 when the children were in Grades Prep-3. In addition to information on putative risk and protective factors for overweight-obesity and direct measures of height and weight, it is unique in having collected data on health-related quality of life (HRQoL) since children were first recruited during the early primary school years. Eight years after the first wave, the children will be adolescents in Grades 8-11. This third wave will retain a focus on HRQoL. Innovations include study of potential emotional, behavioural and physical consequences of childhood obesity that may in turn affect the natural history of obesity. This large, population-based longitudinal study will redress neglected aspects of child and adolescent overweight-obesity specifically identified in 2003 by the NH and MRC. As well as establishing whether a range of common problems are related to overweight-obesity, it will be able to shed light on mechanisms of adverse outcomes associated with adolescent overweight-obesity, and study protective factors predicting remitting overweight from childhood to adolescence that may inform preventive activities. The study will make an international contribution to knowledge about pathways, prevalence and preventive opportunities for child and adolescent overweight-obesity.Read moreRead less
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.
Eco-RESIDE: An Economic Evaluation Of Urban Design As A Means Of Promoting Physical Activity

Summary
The significance of this project lies in the health problem that it seeks to address and the intervention that is being evaluated. 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.

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

Summary
Australia's population is aging rapidly and so is the frequency of age-related diseases. 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 pr ....Australia's population is aging rapidly and so is the frequency of age-related diseases. 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
A Multilevel Study Of Socioeconomic Position And Physical Activity: Environmental And Individual-level Determinants

Summary
Regular physical activity offers many health benefits, whereas inadequate activity is a leading cause of premature death and disability and a major contributor to the increasing prevalence of overweight and obesity. Socioeconomically disadvantaged groups are least likely to be physically active, and they experience higher rates of death and morbidity for conditions directly linked to inactivity. Currently, our understanding of why socioeconomic groups differ in their physical activity is limited ....Regular physical activity offers many health benefits, whereas inadequate activity is a leading cause of premature death and disability and a major contributor to the increasing prevalence of overweight and obesity. Socioeconomically disadvantaged groups are least likely to be physically active, and they experience higher rates of death and morbidity for conditions directly linked to inactivity. Currently, our understanding of why socioeconomic groups differ in their physical activity is limited, and very little research has investigated this issue. This study will investigate why socioeconomic groups differ in their physical activity, by examining the influence of neighbourhood and individual-level factors. Neighbourhood factors include people's access to recreational facilities such as swimming pools, tennis courts, golf clubs, gyms, local parks, walking and bicycle paths; prices for entry to recreational facilities and opening hours; physical characteristics of the neighbourhood including public transport, presence of footpaths and street lighting, speed limits on local streets, availability of local services such as shops and schools, and; aesthetic characteristics, such as the presence and size of parks and green spaces, and traffic density. Individual factors include personal enjoyment, knowledge, confidence, type of occupation and hours worked, family responsibilities, age, health status, and whether other family member or friends engage in physical activity. A major aim of the study is to determine whether environmental or individual factors are more important in influencing participation in physical activity. The study will produce new knowledge to inform future public health strategies directed at increasing physical activity among socioeconomically disadvantaged groups, and these will have the potential to reduce socioeconomic health inequalities, as well as contribute to an overall reduction of the disease burden attributable to chronic conditions.Read moreRead less
