Summary
The effect of lead on children's 'intelligence' is controversial. Poorer IQ scores in children with higher exposure to lead, have been found reasonably consistently, - but there is disagreement on whether lead exposure is simply a common ASSOCIATE of poor IQ, or whether it actually CAUSES deficits. In 1994, the NHMRC prudently recommended a graded series of interventions to be implemented, depending on the proprtion of children in the community with blood lead concentrations in specific categori ....The effect of lead on children's 'intelligence' is controversial. Poorer IQ scores in children with higher exposure to lead, have been found reasonably consistently, - but there is disagreement on whether lead exposure is simply a common ASSOCIATE of poor IQ, or whether it actually CAUSES deficits. In 1994, the NHMRC prudently recommended a graded series of interventions to be implemented, depending on the proprtion of children in the community with blood lead concentrations in specific categories above 10 ug lead -100 ml of blood. The choice of this figure (10 ug-dl) was more pragmatic than scientific; there being very little data on the health effects of exposures below 10 ug-dl available at that time. A recent analysis of pooled data from past studies has now suggested there may be very large effects on child IQ at blood lead concentration BELOW 10 ug-dl. Health authorities will soon be lobbied intensely to spend vast sums on new lead abatement programs. Cities like Port Pirie and Broken Hill (where cooperative programs have achieved such significant reductions in lead exposure that a high percentage of their children now have blood lead levels below 10 ug-dl), will be forced to examine expensive options to avoid closure of the industries which provide their economic backbones, if this analysis proves to be correct. Our proposal argues that before committing to new and costly abatement programs, there is an urgent need to augment our evidence-base by conducting a new study ofchildren with lead exposures below 10 ug-dl, using more modern measures of intelligence. The study will pay closer attention to some of the socio-cultural and inherited determinants of child IQ which may have confounded the lead-IQ association in past studies, and will supplement IQ assessments (which are now considered to derive from a very old and narrow view of intelligence) with new tools for measuring 'intelligence' that may be less socio-culturally dependent.Read moreRead less
Modern Chemical Exposures In Utero And In Infancy, And Their Impact Upon Early Neurodevelopmental Outcomes In The Barwon Infant Study, An Unselected Birth Cohort Study

Summary
I am a paediatric doctor interested in the effects of modern industrial chemicals on children’s development. Even in the womb babies are exposed to industrial chemicals and we know some, like lead, are harmful to developing brains. I am interested in other chemicals that are now suspected to affect development, including the polybrominated diphenyl esters (PBDEs), and I intend to investigate this as part of the Barwon Infant Study, which follows 1250 children from before birth to 3 years.
Achieving Better Mental Health For Maltreated Children: Translating Population Data Into Policy

National Health and Medical Research Council
Funding Amount
$522,706.00
Summary
This project uses linked population data to determine (a) the earliest indicators of risk of harm, and (b) mental health outcomes and health-care costs associated with children receiving child protection services, in partnership with the NSW department of Family and Community Services. The findings will ensure timely and effective responses to the most vulnerable children to mitigate adverse mental health and other outcomes associated with early life adversity.
Role Of Maternal And Obstetric Factors On Long-term Child Health & Educational Outcomes

Funding Amount
$466,492.00
Summary
Natasha Nassar’s research program uses advanced research methods to address new challenges in child health in a portfolio that extends from bench-to-bedside-to-policy. She will investigate the role of maternal health, serum biomarkers, pregnancy complications and obstetric interventions, and birth on subsequent child health and development. Identification of at-risk children and involvement of clinicians and policy-makers should see her research result in improved child health outcomes.
Improving The Developmental Outcomes Of Northern Territory Children: A Datalinkage Study To Inform Policy And Practice In Health, Family Services And Education
Funder
National Health and Medical Research Council
Funding Amount
$952,358.00
Summary
The project uses linked de-identified administrative data sets to study the developmental trajectories of NT children. It investigates the complex interplay of life circumstances including health status, early developmental assessments and demographic data - both individual and community level - all of which influence outcomes including school attendance, performance and retention.

Summary
Most mental health problems begin in childhood and adolescence. Of these, oppositional-defiant and conduct problems in childhood are the most common precursor of all types of adult mental health problems. These children are the most common referral to child mental health clinics but little is known about which of these children will go in which direction i.e., good health, chronic antisocial behaviour, depression and anxiety, substance abuse, the psychoses.

Of these, oppositional-defiant and conduct problems in childhood are the most common precursor of all types of adult mental health problems. These children are the most common referral to child mental health clinics but little is known about which of these children will go in which direction i.e., good health, chronic antisocial behaviour, depression and anxiety, substance abuse, the psychoses. Progress in more accurately defining subgroups of these children would have huge implications for early intervention for mental health problems in our community. This project proposes the first large scale analysis of genetic distributions through to behavioural and treatment factors that characterise and differentiate a large representative sample of children with conduct problems. The project will test a model of child psychopathology that links genotype, via environmental risk and emotion processing problems, to an improved diagnostic-phenotypic model for treatment of the major childhood disorder. Clinical research activities will be structured into three intersecting arms: first, identifying the genetic and behavioural subtypes of early-onset conduct problems; second, innovative treatments for these children, and third, the dissemination of findings to these children and their families via the health care system. The research will build new collaborations between established and internationally recognised clinical research teams in childhood mental health, biological psychiatry, genetics and the Child and Adolescent Mental Health Statewide Network (CAMHSNET). CAMHSNET have specific responsibilities to NSW Health for expert advice and input on the development of child mental health services directions, dissemination, training, and effectiveness research.Read moreRead less
