This project capitalizes on two existing large-scale studies, to increase our scientific understanding of strategies for maintaining the health and wellbeing of older people living in the community. Two separate longitudinal research projects, the Australian Longitudinal Study on Women’s Health involving over 12,000 older women selected from every part of Australia, and the Health in Men Study involving over 12,000 older men from Perth, Western Australia, have been following older Australians in order to determine what contributes to older people’s health and quality of life. The new project will combine data from these two studies. The two projects contain a breadth of data and can address the following questions: What health-related, personal, lifestyle and social factors predict survival and healthy non-disabled life in men and women aged 70-90 years? Do changes in lifestyle in older age (eg smoking cessation) affect length and quality of life? Who makes greatest use of health services, and who least, and how does this relate to health outcomes?How are health and lifestyle factors related to social connectedness and independent living in older age? What health and lifestyle factors predict positive mental health in older age? How are older men’s and women’s lifestyles and health status different, and how are they the same? Should health promotion programs in old age target men and women separately, or not?Read moreRead less

Summary
Overweight and obesity rates are increasing in children, and overweight children have higher risk of adult obesity and therefore diseases including heart attack, stroke and diabetes. The preschool years may offer opportunities to divert children from the path to obesity, before poor physical activity and nutritional habits become firmly established.

The preschool years may offer opportunities to divert children from the path to obesity, before poor physical activity and nutritional habits become firmly established. Adiposity rebound is the time in a child's life (usually around 5 to 6 years of age) when body mass index (BMI) begins to increase after a steady decline in BMI in the preschool years. Early adiposity rebound is associated with increased BMI in later life. We don't yet know whether the early adiposity rebound causes the higher BMI, or whether it is simply an early sign of an already-established pathway of behavioural and environmental risk. We need a much better understanding of predictors of early adiposity rebound and the changes that occur to determine if age at adiposity rebound is a modifiable risk factor for adult obesity. This study will document the process and timing of adiposity rebound and the changes in percent body fat and lean body mass that occur during that time. We will also determine whether risk and protective factors for early adiposity rebound and overweight at age 6 years are the same or different. We will study over 400 children on whom extensive data have been collected since birth, including period of gestation, birth weight and length. At various stages during their first two years of life, height, weight, feeding patterns and development were recorded. We will measure BMI and perform bioimpedance analysis (BIA) on these children six times between 4 and 6 years of age. BIA provides a measure of body fat and lean mass that is well accepted by children. This will help determine the relationship between changing BMI at different ages and the fat-to-lean mass ratios associated with those changes. This study is the first to consider body composition changes during adiposity rebound.Read moreRead less
Contextual Influences On Children's And Adolescent's Physical Activity

Summary
Physical inactivity has been linked to several chronic health conditions among children and adolescents. However, there has been no research that has examined the long-term physical activity habits of Australian children and how these habits change as children move into adolescence. In addition, there is only limited information regarding the factors that influence children's physical activity.

However, there has been no research that has examined the long-term physical activity habits of Australian children and how these habits change as children move into adolescence. In addition, there is only limited information regarding the factors that influence children's physical activity. This study aims to examine changes in physical activity and sedentary behaviours, such as television viewing and computer use, that occur over three years, and also over five years, among children aged 5-6 years and 10-12 years in 2001 (baseline). As such, this study will provide information about children's physical activity habits through primary school and from late primary school to the end of secondary school. The study will also examine the influence of the family and neighbourhood environment on changes that occur in physical activity and sedentary behaviour over that time. This study is significant because it will provide information on the critical transition period between primary and secondary school. The study will identify when changes in these health behaviours occur, the extent of these changes, and the influence of factors in the family environment and the local neighbourhood on changes in these behaviours. Such information is vital to inform the development of strategies to promote and maintain health-enhancing physical activity levels and reduce sedentariness among children.Read moreRead less

These include problems such as tobacco use, depression and anxiety disorders, obesity, alcohol abuse and illicit drug use. However, only a prospective study is able to clarify to what extent common health risk behaviours of teenagers pose a threat to later health and well-being and what characteristics indicate those most likely to go on to problems such as nicotine dependence, recurrent depression and illicit drug abuse. The proposal deals with the follow-up ten years on of a representative sample of 2000 Victorian teenagers. Seven earlier waves of data collections have ascertained levels and risk factors for common behavioural and mental health problems in the teens and early twenties. These problems included depression and anxiety, smoking, heavy alcohol consumption, illicit drug use, deliberate self-harm, obesity, eating disorder, sexually risky behaviour, intravenous drug use, antisocial behaviours and accidental injury. This follow-up of participants at the age of 24 to 25 years will ascertain persisting rates of these problems including levels of substance dependence and mental disorder. Social outcomes such as educational achievement, employment, relationships, parenthood and friendships will be ascertained. In addition mouth washes will be used to collect DNA to allow investigation of genes that may make a contribution to more severe mental disorder and substance dependency. This study will give a clear picture of the outcome and consquences of common adolescent health problems. It will also clarify further psychosocial factors that contribute to their onset or outcome. Together with an analysis of candidate genes the study should make a great contribution to the information necessary for planning effective preventive intervention.Read moreRead less
