It has serious and lasting implications for social and emotional development, cognition, behaviour and literacy. A link has been demonstrated between language impairment and later psychiatric disorders in adolescence and adulthood. Given the potential of enhancing the language development of young children, it is critical that effective prevention and early intervention programs are available. However, current knowledge is liminted in that there are no entirely satisfactory methods for detecting children who at much younger ages, 8 months, 12 months, 2 years and 3 years, are at risk of later impairment. In this study we aim to: examine the risk factors (many are thought to exist) that contribute to language impairment learn more about the natural history of this disabling disorder in children between 8 months and 4 years of age Ultimately, we aim to identify early signs that might warn health professionals and parents of language impairment so that such problems can be detected much earlier. Early identification will mean that help is available at an earlier age to children who currently go on to have persisting and extremely disabling language impairment.Read moreRead less

Summary
Early language and reading problems are common and therefore significant public health problems. They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2.

They are disabling and have life-long implications for oral and written communication skills, social and emotional well-being, cognition, behaviour, academic achievement and employment. This study will address the following three problems: 1. To date no study has documented how language and reading problems develop from infancy (8 months) through to school age (7 years). 2. Little is known about risk factors, identified early in infancy and childhood, that can be reliably used to predict language and reading problems later in childhood. 3. The relationships between language difficulties and reading problems are poorly understood. Therefore, we currently have no satisfactory methods for reliably detecting which children at much younger ages are at risk of later language disorders or reading problems. Without this information it is impossible to develop effective prevention and early intervention programs. These programs are critical if we are to: a) Prevent language and reading problems from occurring, thereby reducing the prevalence of the problem b) Intervene early in childhood, thereby reducing in the longer term the burden and cost associated with language and reading problems. The proposed study builds on an existing substantial investment by the NHMRC in the Early Language in Victoria Study (ELVS). It will provide a world-first description of the evolution of language difficulties and reading problems from infancy through to school age within a single population cohort.Read moreRead less
Impact Of A Sleep Intervention In Children With ADHD: A Randomised Controlled Trial

Summary
Attention deficit hyperactivity disorder (ADHD) affects up to 7.5% of Australian children. Between 50 and 70% of parents also report sleep problems (eg night waking, insomnia) in their child with ADHD. Such sleep problems are associated with poorer child behaviour, concentration, and school attendance as well as poorer parent mental health and work attendance. This randomised controlled trial will determine whether treating sleep problems in children with ADHD can improve these outcomes.
Population Outcomes And Cost-effectiveness Of Universal Newborn Hearing Vs Risk Factor Screening At Age 5 Years.

Summary
Universal newborn hearing screening (UNHS) is being widely implemented because it is thought to greatly improve outcomes for children with congenital deafness. However, it is also very costly. Between 2003-5, all New South Wales babies were offered UNHS, while Victorian babies were offered a risk-factor screening and referral program. This two-year 'natural experiment' paves the way for a unique population effectiveness and cost-effectiveness study of UNHS as the children reach 5 years of age.

Autism is a developmental disorder characterised by a triad of deficits: delayed and atypical language development, impaired development of social skills, and ritualistic and stereotypic behaviour. Although not part of the standard diagnosis, movement disorders and gait abnormalities have been clinically observed in autism similar to those seen in Parkinson's disease.

Although not part of the standard diagnosis, movement disorders and gait abnormalities have been clinically observed in autism similar to those seen in Parkinson's disease. In addition, individuals with Asperger's disorder may appear more clumsy, have a stiff or awkward way of walking, and exhibit poor coordination in posture and gesture. It has been suggested that there is disruption within the basal-ganglia-thalamocortical circuitry (the region connecting the frontal and sub-cortical structures), which may cause the motor dysfunction seen in autism and Asperger's disorder. Few studies have attempted to isolate particular stages of motor functioning which may account for the coordination and motor delay observed clinically in autism and Asperger's disorder. A recent study of ours found evidence to suggest that motor planning deficiencies may account for the 'clumsy' movement patterns frequently reported in the autism - Asperger's disorder literature. Therefore, the aim of this research is to provide a comprehensive neurobehavioural and neurophysiological analysis of motor functioning in young people with autism and Asperger's disorder to further examine the exact stages of motor processing which are deficient in these disorder groups. Recent retrospective studies have shown that even as infants children with autism exhibit clear features of motor disturbance, which, if detected and clearly defined, could advance early diagnosis. In addition to advancing the clinical definition of autism and Asperger's disorder, a careful examination of motor disturbance may also illuminate the neurobiological underpinnings of these disorders.Read moreRead less

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

Over the past 9 years our team has conducted a follow-up study of a large group of 111 Australian children and adolescents with autism. The young people have continued to have very high levels of emotional and behavioural disturbance and generally do not improve. Parents of children with autism are under significant amounts of stress; reporting high levels of disturbed family functioning and mental health problems. Although there is no cure, children benefit most when early help is provided (under 5 years). There are several promising interventions based on intensive behaviour and educational management, for example requiring 40 hours per week of therapist contact over 2 years. Such programs are costly and impractical as widely available treatment options. Training parents to understand and manage their child also shows promise. This study will evaluate the effectiveness of a parent skills training and education treatment program compared to supportive therapy, and to generally available community services. The therapists will follow a treatment manual that will ensure a consistent and replicable approach. The progress of the children with autism and their families will be reassessed immediately after treatment, and at 1 and 2 years post-treatment in order to ascertain immediate and long-term effects of the treatment. If treatment proves to be of use, we will have established a defined, cost efficient, practical and effective model of early treatment that can be easily taught to professionals and widely disseminated throughout early childhood services.Read moreRead less

Approximately 70% of infant death is associated with premature birth. Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled.

Preterm birth occurs in 6-10% of pregnancies, and there has been no reduction in the rates of premature birth in the last 30 years. This is largely because we remain ignorant of how normal and abnormal birth is controlled. Understanding the physiology of human pregnancy is a critical step in the development of ways to detect and prevent preterm birth. Our group has demonstrated a link between production of a hormone (corticotrophin releasing hormone, CRH) in the placenta and the length of time the baby is carried in the mother. In women who will deliver prematurely a rise in CRH occurs earlier in the pregnancy and more rapidly, while in women who deliver late the rise occurs more slowly. This work has given rise to the concept of a biological clock that determines the length of time the fetus will be carried by the mother before birth, and in which production of CRH in the placenta plays a central role. We have been studying how the CRH gene is controlled in placental cells. We have discovered some regions in the DNA of the CRH gene which have important roles in controlling how much CRH is made by the placenta. The experiments described in this research project will determine the molecular mechanisms that control the production of CRH in the human placenta. This will be done in two ways: (1) by examining the DNA sequences involved in controlling expression of the CRH gene and (2) by identifying the proteins that actually perform the regulating functions that result in either increased or decreased amounts of CRH being produced by the placenta. This important information will help us better understand how normal and abnormal birth is controlled, and from that knowledge new ways to detect and prevent premature birth can be invented.Read moreRead less

Summary
Asthma is a chronic condition usually diagnosed in childhood and an important public health concern. We do not fully understand what triggers an asthma attack, although outdoor pollen and moulds may be important. This project will establish the relative importance of pollen and moulds in triggering asthma attacks among Australian children. It will fill gaps in our knowledge of environmental triggers of asthma. Such knowledge will improve asthma management and ultimately public health.
