Summary
The ultimate goal of this study is to define a healthy weight range for Aboriginal people. To fulfil this goal, we will investigate the health implications of body weight and weight change in Aboriginal communities. We will assess the association between body weight (as measured by body mass index) and the risk of death by examining how the death rate changes with body weight.

To fulfil this goal, we will investigate the health implications of body weight and weight change in Aboriginal communities. We will assess the association between body weight (as measured by body mass index) and the risk of death by examining how the death rate changes with body weight. The findings will have important implications for health professionals to provide adequate advice to Aboriginal Australians, and for Aboriginal people to adopt a healthy life style in relation to body weight. Due to the differences in body shape and physiological and environmental factors between Aborigines and other populations, the optimal body weight obtained from other populations may not be applicable to Aboriginal communities. Do males and females have different optimal body weights? Do old and young people have different optimal body weights? This study will provide evidence for answering various questions like these. Individuals with different characteristics may have different optimal body weight values. Such information is useful for the development and modification of dietary guidelines for Aboriginal Australians. The results on the health impact of weight change are important for guiding weight control programs in Aboriginal communities.Read moreRead less
A Population-based Study Of Progression And Risk Factors For Age-related Maculopathy

Summary
Age-related macular degeneration (AMD) is a progressive disease, commencing with the less severe age-related maculopathy (ARM), that ultimately can lead to the loss of fine central vision and personal independence. People with advanced AMD generally retain some mobility if their peripheral vision is maintained, but they are unable to perform tasks such as reading, hobbies or recognising people's faces. Unfortunately, the available treatment for AMD, macular laser photocoagulation, benefits only ....Age-related macular degeneration (AMD) is a progressive disease, commencing with the less severe age-related maculopathy (ARM), that ultimately can lead to the loss of fine central vision and personal independence. People with advanced AMD generally retain some mobility if their peripheral vision is maintained, but they are unable to perform tasks such as reading, hobbies or recognising people's faces. Unfortunately, the available treatment for AMD, macular laser photocoagulation, benefits only a minority of people with this disease. Until safe and effective treatments for AMD can be developed, identification of major risk factors for the development and progression of AMD is essential to determine if interventions aimed at primary prevention can be initiated. This project will expand on the initial findings of the Visual Impairment Project (VIP), a population-based study of age-related eye disease in a cohort of more than 5000 Victorians aged 40 years and older. Data from the VIP have shown that AMD is the most important ophthalmologic public health problem, particularly since AMD is the major cause of vision impairment in Australia and has the least available treatment options. This study will follow individuals who were identified in the VIP with ARM-AMD to determine the natural history and risk factors associated with the longer term progression of AMD. Particular emphasis will be on determining the role of cardiovascular disease risk factors in AMD progression.Read moreRead less
Concord Hormones And Ageing In Men Project (CHAMP)

Summary
Throughout life men have poorer health than women, a health difference that extends into old age. In Australia in 2001, life expectancy for a 65 year old man was 20% less than for a 65 year old woman (81.6 years for men and 85.2 years for women). The study proposed here will fill major gaps in knowledge about key health problems in older men. The study will be called CHAMP: Concord Hormones and Ageing in Men Project.

In Australia in 2001, life expectancy for a 65 year old man was 20% less than for a 65 year old woman (81.6 years for men and 85.2 years for women). The study proposed here will fill major gaps in knowledge about key health problems in older men. The study will be called CHAMP: Concord Hormones and Ageing in Men Project. As people grow older, health problems that cause loss of independence and reduced quality of life become increasingly important. The term 'geriatric giants' is sometimes used to describe these disabling syndromes: falls and fractures, cognitive impairment and dementia, urinary incontinence, and poor mobility and functional dependence. CHAMP has been designed to investigate the causes of, and inter-relationships between, these geriatric syndromes in men. Reproductive hormones are responsible for the fundamental biological differences between men and women. Underpinning CHAMP is the idea that age-related changes in reproductive hormones play an important role in the development of the geriatric syndromes in older men. There have been numerous studies of oestrogen and health in older women but only limited research on testosterone and other reproductive hormones in older men. CHAMP will be the largest study of the geriatric syndromes in older men ever conducted. The study will inlvolve 2800 men aged 65 years and over recruited from the community around Concord Hospital in Sydney. These men will each spend 3 hours at the study centre, where they will have a comprehensive physical examination and tests for osteoporosis, muscle weakness, dementia and urinary problems, as well as blood tests. This will all be repeated 2 years later.Read moreRead less
Genes And Environment In The Risk Of Early Age-Related Macular Degeneration: A Population-based Case-Control Study
Funder

Funding Amount
$949,588.00
Summary
This study will pool data from three well-conducted population-based cohorts of older persons to gain a large sample size in order to investigate the interplay of genes and environmental factors on the risk of age-related macular degeneration (AMD). The study will give insights into AMD pathogenesis, and enable potential targeting of people with AMD susceptibility genes for preventive approaches. These could ultimately reduce the burden of this blinding condition.
Genes And Environment In Late AMD: Pooling A State And Population Resource

Funding Amount
$701,642.00
Summary
This study will pool cases from the West Australian Macular Degeneration database with the Blue Mountains Eye Study (NSW), to investigate the interplay of genes and environmental factors on risk of age-related macular degeneration (AMD), in particular the late, vision threatening stage. It will provide insights into the underlying causes of AMD, and could allow us to target people with AMD susceptibility genes for preventive approaches, which could reduce the burden of this disease.
