There are many unresolved issues regarding nutrition in old age such as the obesity paradox, protein intake requirements, and dietary needs of obese and frail older people. We have developed a nutritional model, the Geometric Framework, which has the capacity to address complex questions about the relationship between nutrition and ageing and have an established cohort of older men that will allow us to investigate multiple factors involved in age-related changes in nutrition and obesity.

Summary
The potential risk to caregivers of dementia patients of poor health outcomes is well documented. The burden imposed by caregiving is most often described in terms of chronic stress. While it is apparent that some stress-relieving social interventions (e.g. respite) may have short-term benefits, it is also clear that many caregivers are unable or unwilling to avail themselves of such programs. The way in which chronic stress leads to poor health is not well understood.

The burden imposed by caregiving is most often described in terms of chronic stress. While it is apparent that some stress-relieving social interventions (e.g. respite) may have short-term benefits, it is also clear that many caregivers are unable or unwilling to avail themselves of such programs. The way in which chronic stress leads to poor health is not well understood. Our study of spouse caregivers seeks to identify the groups of physiological systems that suffer cumulative wear and tear as a result of chronic stress. This wear and tear is called allostatic load, and is thought to lead to poor health. It is expected that caregivers in our study will have greater allostatic load than people who are not caregivers. Should this be the case, our results will provide the basis for the design of tailored interventions to maintain caregivers in good health. The potential of such preventive health measures is to reduce caregivers' health care costs and reliance on community support, and to help caregivers to continue providing care for their spouses at home.Read moreRead less
Randomised Controlled Trial Of A Tailored Podiatry Intervention To Enhance Mobility And Prevent Falls In Older People

Summary
Foot problems affect 1 in 3 people over the age of 65 years and are associated with reduced walking speed, difficulty performing activities of daily living, impaired balance and increased risk of falls. Although a range of health professionals provide treatment for foot disorders, the most common chronic foot problems in older people (such as corns and calluses, nail disorders and toe deformities) are frequently managed by podiatrists using treatments such as scalpel debridement of lesions, foot ....Foot problems affect 1 in 3 people over the age of 65 years and are associated with reduced walking speed, difficulty performing activities of daily living, impaired balance and increased risk of falls. Although a range of health professionals provide treatment for foot disorders, the most common chronic foot problems in older people (such as corns and calluses, nail disorders and toe deformities) are frequently managed by podiatrists using treatments such as scalpel debridement of lesions, foot orthoses, exercise prescription and footwear modifications. The 1995 National Health Survey reported that persons aged 80 years or over were most likely to have reported visiting a podiatrist in the previous two weeks, followed by those aged 65-79 years. Similarly, the Australian Department of Veterans Affairs, which provides podiatry services to veterans and their dependants, documented 606,706 episodes of podiatry care to 103,540 veterans in 1998-1999, at a cost of $23M. Podiatry therefore plays a substantial role in the maintenance of foot health and mobility in older Australians. Despite the detrimental effects of foot problems and the widespread utilisation of podiatry services by older people, very few studies have been undertaken to ascertain the efficacy of podiatry treatments. Therefore, the aim of this study is to evaluate the efficacy of an individualised podiatry intervention designed to reduce pain, enhance functional mobility and prevent falls in older people. Given the high prevalence of foot-related disability and falls in older people and their associated health care costs, the study findings will be of considerable public health importance. If found to be clinically effective, the intervention could be easily implemented into a range of healthcare settings and adopted in both state and federal falls prevention policies.Read moreRead less

There is already some evidence that deficiency in certain vitamins may be contributing to these problems. This project seeks to evaluate an inexpensive and simple vitamin supplement which may provide a highly cost-effective method of preventing cognitive decline, dementia and depression in older people. This research will also allow the evaluation of the role of certain biological and genetic risk factors which may also impact on these problems. This project seeks to do a trial of these vitamins in older men who are at particular risk for these problems. The men in this project will be monitored by simple tests of their thinking and evaluating any symptoms of depression.Read moreRead less
Predicting Health And Disease In Australian Men Over The Age Of 80 Years - The Health In Men Study

Summary
Australia is ageing rapidly but we still do not know whether the risk factors, such as health and lifestyle, that predict ill health in middle aged people, apply to people as they reach old age. This study of a large group of older men will examine the type and level of risk factors that apply to men aged beyond 75 years. It will not only determine rates of disability and mortality but also health service outcomes, including hospitalisation, and residential and community care usage.

Summary
Asthma is a major Australian health priority affecting over 2 million people. It is under-diagnosed and a source of significant morbidity in older people. Previous work by the investigators for the Commonwealth of Australia has shown that in the over 55-year age group approximately 40% of asthma is undiagnosed. In this age group severity is comparable with those diagnosed and worse than those diagnosed under the age of 55 years.

It is under-diagnosed and a source of significant morbidity in older people. Previous work by the investigators for the Commonwealth of Australia has shown that in the over 55-year age group approximately 40% of asthma is undiagnosed. In this age group severity is comparable with those diagnosed and worse than those diagnosed under the age of 55 years. Most (80%) of asthma deaths occur in the people aged greater than 55 years. There are clear patient and system factors that contribute to under diagnosis. The patient factors are currently being addressed in a general practice patient pilot study. System issues make the diagnosis of asthma in general practice a difficult task. The study is important, as older people are more likely to access the general practitioner than a specialist for respiratory problems. Spirometry in general practice is not common and is of variable quality. The most common approach to diagnosis by the general practitioner is a diagnostic trial of medication to provide evidence of asthma. This can be broken down into four elements of: entry criteria to a therapeutic trial; choice of drug in a therapeutic trial; length of time for a therapeutic trial, and; assessment criteria in a therapeutic trial. No evidence-based guidelines are available to assist the general practitioner in each of these stages making the therapeutic trial a safety and effectiveness issue of major importance, especially in the older person. The purpose of the study proposed is to conduct a randomised controlled trial in a representative population sample of older people to determine the evidence-based components of a diagnostic therapeutic trial for the guidance of general practitioners. The study will also assess which diagnostic questions and medical tests provide greatest assistance to the general practitioner in diagnosing asthma in the older person.Read moreRead less

Summary
Insomnia is very common in the elderly and is associated with increased morbidity and reduced quality of life. Yoga is purported to assist with sleep and stress management but there is little rigorous research to confirm this and no research to determine if yoga can be adapted to an elderly population in Australia. This study aims to rigourously examine the effectiveness of yoga as an intervention for geriatric insomnia and to determine the ability of yoga to enhance quality of life.
