Summary
Respiratory diseases such as asthma, chronic obstructive airway disease, and sleep apnoea are common in the community, and asthma is becoming more and more common. These diseases are a major cause of morbidity, lost time from work, use of health and community resources and death. Using information collected by the Busselton Health Studies between 1966 and 2000, we will investigate some new epidemiological aspects of respiratory diseases. Some of the questions we will examine are: * How much more ....Respiratory diseases such as asthma, chronic obstructive airway disease, and sleep apnoea are common in the community, and asthma is becoming more and more common. These diseases are a major cause of morbidity, lost time from work, use of health and community resources and death. Using information collected by the Busselton Health Studies between 1966 and 2000, we will investigate some new epidemiological aspects of respiratory diseases. Some of the questions we will examine are: * How much more common has asthma become in the Busselton population? Has the increase been more pronounced in some groups than in others (eg younger people)? Have other respiratory diseases also become more common? * Is decline in FEV1 over time a more useful measure of lung health than a single FEV1 measurement? How is decline in FEV1 related to age and other factors such as asthma, smoking, chronic respiratory diseases and hay fever? * Do the following put people at increased risk of sleep apnoea: overweight, recent weight gain, smoking, heavy alcohol intake, respiratory illness, cardiovascular disease and use of sedatives? * Do non-smoking spouses of smokers suffer more respiratory illness than spouses of non-smokers? We expect that results from this study will increase our understanding of the causes and progression of respiratory diseases, and may eventually point to ways of reducing the burden of these diseases in the community. Since all the information needed has already been collected in the course of earlier health surveys, this study will be particularly cost-effective.Read moreRead less
Reducing Indoor Air Pollution In The Home: A Randomised Controlled Trial Of A Behavioural Intervention.

Summary
Exposure to air pollution is not confined to pollution emitted outdoors by motor vehicles and industry. We are exposed to a diverse and complex mix of indoor pollutants produced in many cases by everyday activities. Since we spend about 70-90% of our time indoors, the potential effect of these pollutants on our health is important and of concern. There is a growing number of scientific studies that confirm the importance of indoor air pollution to our health.

We are exposed to a diverse and complex mix of indoor pollutants produced in many cases by everyday activities. Since we spend about 70-90% of our time indoors, the potential effect of these pollutants on our health is important and of concern. There is a growing number of scientific studies that confirm the importance of indoor air pollution to our health. Two indoor pollutants commonly found in the home are nitrogen dioxide (NO2) emitted from gas appliances and environmental tobacco smoke (ETS). ETS, or passive smoking, is known to increase lower respiratory tract illness in children, asthma, lung cancer and cardiovascular disease. Studies have shown that NO2 may increase respiratory symptoms and exacerbate the response of asthmatics to allergens such as house dust mites. In this project we extend our earlier work on indoor air pollution, with the aim of evaluating simple and effective ways to improve air quality in the home. Parents of school children from the Newcastle area will be invited to participate in the study. Parents will receive information about the health risks of indoor air pollution and advice on how to decrease the levels in their home. We will monitor the air quality in each participant's home to see whether the education program has helped parents to decrease the levels of NO2 and ETS in their home. We will also examine whether a reduction in these pollutants has improved the lung health of the children in the study.Read moreRead less
Unintended Adverse Effects Of Advertising For Nicotine Replacement Therapies

Summary
Advertising for certain pharmaceutical products (nicotine replacement therapy( NRT)) to help people quit smoking has been permitted in Australia since 1997. Zyban, an antidepressant drug, has been found to be helpful in quitting smoking, but advertising has not yet been permitted in Australia although it is allowed overseas.

Zyban, an antidepressant drug, has been found to be helpful in quitting smoking, but advertising has not yet been permitted in Australia although it is allowed overseas. Because such advertising will reach more than the primary target group of heavy smokers ready to quit, it is important to consider the responses of other smokers who are not ready to quit and those at risk of taking up smoking. There is concern that there may be 'boomerang' effects, albeit unintended, on these population groups, because they may feel reassured that there is an effective method to quit and so be in no rush to quit soon, they may try to quit using these products before they are really ready, and in the case of teenagers, they may think that these products make it easy to quit, so there is less problem with starting to smoke. In order to assess if this is so, we will randomly allocate smokers not yet ready to quit and teenagers to either (a) a group where they view 3 ads promoting non-drug methods of quitting, such as the Quitline, (b) a group where they view 3 ads promoting the NRT gum or patch, or (c) a group where they view 3 ads promoting Zyban as a method for quitting. The study will use questionnaires to assess whether, compared with those viewing the non-drug anti-smoking ads, those viewing the NRT or Zyban ads think smoking is less addictive and have less intention to quit, or in the case of teenagers, have more intention to take up smoking. This project will be the first formal study to assess whether there may be adverse effects of NRT and Zyban advertising on smokers not yet ready to quit and teenagers who are not already regular smokers. For this reason, the study will help an assessment of the risks of such advertising compared with the established benefits for smokers who are ready to quit.Read moreRead less

Summary
The prevalence of smoking among people with a psychiatric illness, especially schizophrenia, is greater than that in the general population. Exposure to tobacco smoke has been identified as a cause of 32 different diseases as well as a cause of fire injuries. Tobacco smoke is known to contain carcinogens, as well as nicotine and numerous other poisonous substances. An extensive body of scientific evidence shows that active cigarette smoking increases the risk of many different cancers.

Exposure to tobacco smoke has been identified as a cause of 32 different diseases as well as a cause of fire injuries. Tobacco smoke is known to contain carcinogens, as well as nicotine and numerous other poisonous substances. An extensive body of scientific evidence shows that active cigarette smoking increases the risk of many different cancers. Smoking related diseases rate second in frequency to suicide as the greatest contributor to early mortality in schizophrenia. Popular opinion holds that people with mental illness are lacking in motivation to change their behaviour due to the effects of their mental illness. However, a recent survey of inpatients in a psychiatric hospital in Newcastle, NSW, revealed that over a quarter of smokers were either preparing to quit or cut down on their smoking or already had taken action to reduce their smoking. The present research proposal represents the first large randomised controlled trial of an intervention for tobacco dependence among people with a mental illness. This project will compare the effectiveness of nicotine replacement therapy combined with counselling with a self-help booklet on smoking. The proposed research follows a small clinical study of the feasibility of the intervention and a small randomised controlled trial supported by the Australian Rotary Health Research Fund. The proposed study brings together the expertise of several people across Australia who have experience in treating people with mental illness and drug dependence, including tobacco dependence. The results will inform future clinical interventions for smokers with a mental illness.Read moreRead less
