Summary
This multi-factorial project will extend the follow-up of 4 large, established groups of people who have experienced significant exposure to asbestos, silica or diesel, either through their jobs, or environmentally. Mesothelioma, lung cancer and prostate cancer are common among these groups. The study will provide important information on the effects of different levels of exposure to these three cancer-causing agents, as well as their effects on chronic respiratory diseases such as asbestosis, ....This multi-factorial project will extend the follow-up of 4 large, established groups of people who have experienced significant exposure to asbestos, silica or diesel, either through their jobs, or environmentally. Mesothelioma, lung cancer and prostate cancer are common among these groups. The study will provide important information on the effects of different levels of exposure to these three cancer-causing agents, as well as their effects on chronic respiratory diseases such as asbestosis, silicosis, asthma and tuberculosis. Ways in which these diseases may be prevented through the diet and other lifestyle habits (including smoking, alcohol consumption and exercise), will be closely examined. This study will also help to identify the genes which may place some people at a higher risk than others.Read moreRead less
The Relationship Between Airborne Particle Exposure, Incident Respiratory Symptoms And Decline In Lung Function

Summary
Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited som ....Air pollution has been consistently identified as the environmental health problem of greatest concern to the general public in Australia. Yet hard evidence of adverse health effects from air pollution in Australian cities and towns is limited to date. It has been estimated that high levels of particles in urban air could be responsible for as many as 2,400 deaths nationally, costing approximately $4,300 million each year. This study will follow two groups of young Melbourne adults recruited some years ago for studies of respiratory health. They will be a sent a questionnaire by mail and invited back to our laboratory for breathing tests. We will obtain routinely collected air quality data and measure fine particles < 2.5 thousandths of a mm in outdoor air. A subgroup of 100 subjects will also participate in some measurements of indoor air pollution. The analysis will look for relationships between particles in the air, new symptoms and changes in lung function over time. Comparisons will also made with other centres doing a very similar study in Europe. Reviews commissioned by the National Environment Protection Council have highlighted the lack of Australian data to assist in setting standards for particulate air pollution. The proposed study would provide some of the necessary local data and assist in the development of new health based environmental protection measures for fine particles. Once these measures have been implemented, we would expect to see an improvement in the respiratory health of the Australian population.Read moreRead less

Summary
Chronic obstructive pulmonary disease (including chronic bronchitis and emphysema) is a major public health problem in Australia. The main known cause is cigarette smoking, which peaked among Australian men shortly after the second world war. Now that the consequences of this epidemic of smoking are passing, more attention needs to be paid to other causes of the condition. The proposed study will focus on occupational and domestic exposures and dietary factors in older people.

The main known cause is cigarette smoking, which peaked among Australian men shortly after the second world war. Now that the consequences of this epidemic of smoking are passing, more attention needs to be paid to other causes of the condition. The proposed study will focus on occupational and domestic exposures and dietary factors in older people. Dusty jobs have long been associated with COPD. However it is not known to what extent other occupational exposures to fumes and vapours are also responsible. Identifying such jobs would lead to better workplace conditions and prevention of further cases. Workers who have already developed COPD could be more fairly compensated. Similarly if indoor exposures to tobacco smoke and unvented gas appliances were found to play a role, further controls on smoking, flues and improved ventilation could also prevent cases of COPD. It is generally thought that emphysema develops from an imbalance between the oxidative stresses on the lungs and protective enzymes. A diet high in antioxidant vitamins and fish may protect against the development of COPD. If confirmed by this study, it would then be possible to conduct clinical trials of supplementation in smokers at risk of developing COPD. Public nutritional education could reduce the incidence of the condition in the future.Read moreRead less
