Summary
Sedentary behaviours and physical inactivity play a major role in the rising prevalence of obesity among children in Australia. This intervention study will take place in the school and family settings which play a critical role in shaping children's health behaviours. The objective is to determine whether a 2-year behavioural intervention reduces sedentary behaviour and promotes physical activity and results in improved health among 8-9 year old children.

Summary
In Australia, one in four school-aged children is currently overweight and childhood obesity rates are continuing to rise. In the last five years it has become clear that rates of overweight and obesity are also rapidly increasing in pre-school age children. These are issues that are of concern to health officials as well as to parents.

In the last five years it has become clear that rates of overweight and obesity are also rapidly increasing in pre-school age children. These are issues that are of concern to health officials as well as to parents. We understand that these rising rates in fatness relate to children's diet and activity patterns, and that these patterns, once established are likely to be patterns for life. To date, there has been relatively little research regarding the chance to support parents to establish the eating and activity patterns that will protect their children from the very beginning of life. This project seeks to support first-time parents to establish healthy eating and activity behaviours in their children using the highly utilised Maternal and Child Health Centres first time parents' groups. We believe that these groups will provide a strongly supportive environment in which to provide parents with strategies and knowledge for promoting healthy eating and activity patterns for their children, and in turn, promote healthy weight gain. This project will assess the effectiveness of this intervention.Read moreRead less
RCT Of The Impact Of Electronic Game Use By Children On Physical Activity And Energy Expenditure

Summary
Increasing childhood obesity and reduced physical activity are major health issues in Australia. Three quarters of Australian children play electronic games and this is widely thought to reduce their physical activity. Whilst the effect of TV viewing is well understood, the impact of electronic games is not. This study will test whether access to electronic games results in decreased physical activity in children. We need to understand the impact this popular activity is having on child health.

Summary
Children who are obese have a higher risk of numerous health problems, including high blood pressure, high cholesterol and joint problems. They also experience reduced self-esteem and discrimination as well as an increased risk of premature death or poor health due to heart disease and Type 2 diabetes in adulthood. Approximately 25% of Australian children are overweight or obese. This prevalence has doubled since the 1980's and is still increasing.

They also experience reduced self-esteem and discrimination as well as an increased risk of premature death or poor health due to heart disease and Type 2 diabetes in adulthood. Approximately 25% of Australian children are overweight or obese. This prevalence has doubled since the 1980's and is still increasing. Child obesity is a major public health problem and innovative approaches to solving this problem are urgently needed. A range of factors has been postulated as contributing to the global childhood obesity epidemic, including environmental, psychosocial, physical, nutrition, metabolic and lifestyle factors. However, the major determinants involve a shift away from energy balance through reduced energy expenditure or physical activity and increased energy intake. Conventional weight-management strategies have incorporated restricting energy intake or diet, increasing energy expenditure or physical activity, decreasing sedentary activities, parental involvement, and behaviour modification. However, these strategies have only shown moderate success among children in the medium to long term and very few can be translated into community settings. The purpose of this study, and its original contribution to research, is to determine the impact of a physical activity skill development and parent-centred family weight management program on the weight, cardiovascular health, physical activity, dietary intake, and sedentary behaviours of overweight and obese children.Read moreRead less
Overweight/obesity, Activity Patterns, And Health In 4-year-olds: The Longitudinal Study Of Australian Children

Summary
Levels of overweight and obesity are at an all-time high, but we know little about: - its prevalence in young Australian children - the activity patterns of young children and how this relates to overweight-obesity, at an age when lasting patterns of sedentary behaviour are becoming established. A better understanding of this relationship is important, because low levels of physical activity are probably a major driver in the current epidemic - how overweight-obesity affects very young children ....Levels of overweight and obesity are at an all-time high, but we know little about: - its prevalence in young Australian children - the activity patterns of young children and how this relates to overweight-obesity, at an age when lasting patterns of sedentary behaviour are becoming established. A better understanding of this relationship is important, because low levels of physical activity are probably a major driver in the current epidemic - how overweight-obesity affects very young children - how a familial predisposition to gain weight is translated into excessive weight gain during early childhood The present study will utilise data collected as part of the Longitudinal Study of Australian Children (LSAC). In March 2004, LSAC will enrol a nationally-representative cohort including 5000 4-year-olds for comprehensive longitudinal study, with the first wave of data available for analysis in April 2005. A unique feature of LSAC is direct measurement of children's weight and height coupled with detailed data about their use of time and health-related quality of life (HRQoL). The availability of these data will enable us for the first time to study the relationship between childhood overweight-obesity, detailed activity patterns of young children, parental overweight-obesity and the relationship between these variables and children's HRQoL. In late 2003, the National Health and Medical Research Council published its evidence-based Clinical Practice Guidelines for the Management of Overweight and Obesity in Children and Adolescents. This application addresses several of its key research recommendations, far more efficiently than could be done if a new study had to be set up specifically for this purpose. The proposal acknowledges the common problem of under-funding for analysis of important large datasets, and seeks to address this issue right from the start of LSAC.Read moreRead less
Do People's Environments Influence Their Habitual Physical Activity?

Or, they send off e-mails instead of walking down the corridor at work. The result is that people are not using up the energy that they should and they get fatter. The average weight of many groups of Australians has gone up by several kilograms in the past 10 years. Active people not only have healthier weights. They are less likely to get heart disease, diabetes and some cancers. But too many people do no exercise at all. Only about 10% of Australians adults do fitness and sporting activities three or more times a week. More than half do not walk, cycle or do anything moderately active on any regular basis. To get people to be regularly active and to stay active, promoting deliberate 'exercise' is not the answer. Making it easier for people to choose to be more active as they go about their daily lives will be more effective. Road transport researchers and geographers have a lot to offer to health researchers. They have found that where there are footpaths and cycle ways, where shops and businesses are close by or where the roads make it easy and safe to get from place to place, people are much more likely to walk or ride bikes. We can now use large, complex computerised databases (called Geographic Information Systems) to put together this type of information on peoples' local environments. We will combine these 'geographic' data with other information from surveys on people's physical activity, exercise and transport habits. Starting our research in this way, we will be able to work out whether there are factors in people's local environments that really do make them less active. Governments, health planners and local councils will use this information to find ways to create communities that are more activity-friendly. This will have real health benefits.Read moreRead less

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
Efficacy Of Exercise Physiologist Counselling In Primary Care Patients: A RCT Of Two Pragmatic Approaches

Summary
Physical activity is one of the most powerful contributors to health, but population levels of activity are low. General practitioners (GPs) are well placed to provide physical activity counselling, but many are too busy. This project examines the effectiveness of referral of insufficiently active adults to an exercise physiologist (EP), using step counts from a pedometer as the outcome. We compare usual care from the GP with: (1) 5 EP visits, and (2) a single visit and telephone follow up.
Understanding The Acute And Cumulative Metabolic Effects Of Prolonged Sitting In Adults

Summary
Sedentary behaviour (sitting time) has been linked to an increased risk of chronic illnesses, including type 2 diabetes and obesity, but recent evidence suggests that light-intensity activity (non-exercise activities of daily living) is associated with reduced risk. These studies will examine whether breaking up sitting time with frequent short periods of activity can overcome the negative effects of prolonged sitting on blood glucose and blood fats in overweight older adults.
