Children's Health and Environment Program

The Children's Health and Environment Program (CHEP) is part of the Child Health Research Centre at The University of Queensland. Under the leadership of Professor Peter Sly, the program has been designated for the second time as the World Health Organization (WHO) Collaborating Centre for Children's Health and the Environment.

The WHOCC is a member of the WHO network for Children's Environmental Health-Read more below.

What is Children's Environmental Health?

Young children interact with the environment in their homes, and in educational or child care establishments through breathing air, consuming food and water, and through "mouthing behaviours" in which they put their hands, feet, and other objects into their mouths resulting in non-nutritive ingestion.

Trans-placental transfer, breast milk and non-nutritive ingestion result in unique exposure pathways for children. It is therefore critical that we understand the level of contamination within these environments so that we can assess exposure and risk and health impacts.

Did you know that children breathe more air, drink more water, and eat more food per pound of body weight than adults? This makes them at higher risk of ill effects from harmful contaminants in the environment.

Why is research in environmental health needed?

The global pattern and causes of disease have changed. The Lancet Commission on Pollution and Health states that pollution, in its broadest sense, is the largest cause of disease and premature death in the world today. Pollution caused three time more deaths than AIDS, tuberculosis and malaria combined in 2015.

Globally, early childhood deaths and deaths from communicable, maternal, neonatal, and nutritional disorders have declined. In contrast, deaths from non-communicable diseases (NCDs) are increasing; accounting for 70 per cent of all deaths globally today.

The Australian situation is no different with high incidence of NCDs including obesity, type 2 diabetes, cardiovascular disease (CVD), asthma, chronic obstructive pulmonary disease (COPD), and neurobehavioral problems. As NCDs become more prevalent, the future costs of diagnosis and treatment are likely to increase dramatically, thus highlighting an imperative to intervene in early life, optimise nutrition and prevent and reduce exposure to hazardous chemicals/toxicants.

Our modern Australian environments are contaminated by an increasing variety of chemicals that increase the risk of NCDs, yet public awareness of the risks, and of avoidable exposures, is low. Low awareness contributes to human behaviours that perpetuate and even increase exposures to these pollutants.

Ecological exposures include contamination of air, water, soil and the food chain by environmental toxicants from large scale industries, such as extractive industries, flame retardants and per- and poly- fluoroalkyl substances (PFAS) from fire-fighting foam, and agricultural pesticides, potentially affecting populations living in the vicinity of these activities. As an example, extractive industries play an important role in the Australian economy but may pose a special risk to those living around them from environmental contamination, change in land use, social disruption and population displacement.

Modern household exposures include: plastics and plasticisers; flame retardants; pesticides; cleaning products; and personal care products – all of which can have adverse health effects.

Ambient air exposures include: combustion-related products from traffic; wood smoke; bushfires; coal-fired power generation; and industrial emissions.

The role of the Children's Health and Environment Program

While the general public is becoming better informed and increasingly concerned about adverse environmental influences on health, the environmental threats to the health of children are not high on the research agenda in Australia.

From our location within the Centre for Children's Health Research (adjacent to the Lady Cilento Children's Hospital), the Children's Health and Environment Program is well-placed to develop a coordinated and ambitious plan for children's environmental health research to improve outcomes for children in Australia, and internationally.

Our research aims to keep children safe from DETRIMENTAL and AVOIDABLE environmental exposures, reduce life-long risk of non-communicable diseases (NCD), and improve clinical outcomes by investigating:

  • how environmental exposures impact on NCD risk,
  • the mechanisms of NCD development following environmental exposures,
  • the populations within Australia that face the most risk at a population level, and
  • how to protect children from environmental exposures so they can live safer, healthier lives.

Ultimately our goals are to:

  • generate new knowledge and evidence of the links between environmental exposures and disease mechanisms,
  • translate research into improved public health policy and clinical practice,
  • train the health workforce to recognise and respond to environmental exposures, and
  • collaborate widely to ensure public engagement and to positively influence environmental and public health policy for effective and efficient prevention for improving life-long health.

WHO Collaborating Centre for Children's Health and Environment

Research interests

We have a range of projects being undertaken under the following areas of interest:

Public Health

CHEP has established collaborations with the School of Public Health, The University of Queensland (SPH) to add a children's environmental health focus to the Master of Public Health (MPH) program and to offer opportunities for prospective Higher Degree Research Students.

Areas of collaboration include assessing the environmental contribution to the burden of disease in children, increasing the "child" focus of existing and new population health research, and developing joint education programs in children's environmental health.

Environmental Exposures

Collaborations with Queensland Alliance for Environmental Health Sciences (QAESH), The University of Queensland have already been established combining expertise in quantifying exposures to harmful chemicals in the environment with paediatric epidemiology and health outcome expertise. Strong collaborative links have been established, in particular with Professor Jochen Mueller and Professor KevinThomas.

Collaborative studies underway or in the planning include:

  • Optimising techniques for assessing exposure of infants and young children to environmental chemicals,
  • Measuring environmental exposures and their health consequences in birth cohort studies.

Little Things Matter: The Impact of Toxins on the Developing Brain

A seven minute video, presented by Dr Bruce Lanphear, helps people understand the population impact of exposures to environmental toxins. After studying the impact of toxins on children for many years researchers have reached the conclusion that “little things matter”. The presentation is very graphical and easy to follow and ends with a list of suggestions to help avoid exposure to toxins.

Environmental Infections

Evidence is accumulating that climate change is resulting in a change in the distribution of infections, especially food, water, and vector-borne diseases.

Such changes will result in Australia facing an increase in diseases our work force is not trained to handle. Collaborations within CHRC (Infection, Inflammation and the Environment theme) and with The University of Queensland Australian Infectious Disease (AID) Research Centre will see CHEP well placed to contribute to an improved outcome for Australian children.

In addition, we have seen the impact on human health of zoonoses. Existing collaborations between CHRC and the School of Veterinary Science, The University of Queensland can be extended to help address such issues in children's health.

Neurodevelopment and Mental Health

CHEP is collaborating on several projects investigating the impact of environmental exposures on neurodevelopment and mental health in children. CHEP and Queensland Alliance for Environmental Health Sciences (QAESH) are providing expertise in environmental monitoring to the Barwon Infant Study, co-ordinated by Dr. Peter Vuillermin and Professor Anne-Louise Ponsonby, Murdoch Children's Research Institute, Melbourne.

Associate Professor James Scott has joined CHEP as an "external member" and will lead a Mental Health Group. Initial research will centre on bullying in children.

Education and training

There is a general lack of awareness of the particular vulnerability of children to adverse environmental exposures. To raise awareness of environmental exposures and the risk to children, we are collaborating with schools at The University of Queensland to produce and deliver educational material on children's environmental health targeted to undergraduate and postgraduate students, the continuing education of health care professionals, environmental health officers, and interested members of the public.

Education for Higher Degree Students

CHEP has a focus on education and training, adding a children's environmental health component to Masters Level education and short summer courses in the School of Public Health, in conjunction with Dr Luke Knibbs. CHEP staff currently contribute to the supervision of 12 RhD students at UQ and have had 3 successful PhD completions since 2014.


Collaborations, outreach and engagement

Our Collaborations

To maximise our impact, we have forged strong and active local and international collaborations.

Within The University of Queensland, we have strong partnerships with the Queensland Alliance for Environmental Health Sciences (QAEHS), formally known as the National Centre for Environmental Toxicology (ENTOX), the School of Public Health, and the Global Change Institute.

External to The University of Queensland, we collaborate regularly with:

We also work with scientists to conduct research programs in developing countries including Brazil, Thailand, China, Mexico, India and South Africa. Collectively, these collaborations enable us to conduct research with global reach and relevance. It also means students and staff have the opportunity to gain exposure to, and experience with, major international and national environmental health groups.

Public Engagement

CHEP provides The University of Queensland with the opportunity to take a leadership role in engaging the public in children's environmental health and in child health advocacy. CHEP has recently taken over producing the Healthy Environments for Children Alliance newsletter, a joint venture from WHO and the United Nations Environment Program (UNEP). By engaging with public interest groups, such as the National Toxics Network we can supply accurate information that will increase public awareness and ensure The University of Queensland is at the forefront of discourse relating to childhood environmental exposures.
