A recent study published in Public Health Research & Practice has revealed that reducing the prevalence of childhood obesity in Australia by just 5 per cent could save the economy a staggering $7.44 billion over the lifetimes of today’s children and teens.
The findings, spearheaded by Dr Joe Carrello and supported by the Australian Prevention Partnership Centre, underscore the financial and health incentives of public health prevention.
The study also highlights that each child or teen living with excessive weight incurs an additional lifetime cost of approximately $19,700, while those with obesity face additional costs of around $46,700. These expenses stem largely from increased healthcare needs and productivity losses.
With approximately 25 per cent of Australian children and adolescents currently classified as overweight or obese, this research aligns with the National Obesity Strategy 2022-2032, which aims to reduce these rates to 20 per cent by 2030. The study’s findings reinforce the urgent need for early preventative action.
Our commitment to healthier food environments
As the North Eastern Public Health Unit (NEPHU), we are not only welcoming these findings but actively working to address the root causes of childhood obesity within our communities. Our Population Health Catchment Plan for 2023-2025 identifies healthy eating as a priority area, reflecting our commitment to reshaping the local food environment to support healthier choices and tackle systemic barriers to good health.
NEPHU’s role involves a multifaceted approach to improving food access, promoting sustainable food systems, and driving change in the broader determinants of health across our catchment area.
Reducing obesity is not about encouraging individual behaviour change; it requires a shift in how we think about health as a community and a fundamental change in the physical and commercial determinants of health to provide health promoting environments.
Supporting families in establishing healthy habits early in life is key to long-term success in obesity prevention. One of NEPHU’s initiatives is to amplify programs such as the INFANT program (Infant Feeding, Active play and Nutrition), a state-based initiative supporting parents in promoting healthy eating habits during the first 2000 days of a child’s life.
INFANT is now included in The Australian Institute of Family Studies guidebook on evidence-based programs, and is approved for use under the 50 per cent requirement for Communities for Children Facilitating Partners for organisations running programs funded by the Department of Social Services (DSS).
Through INFANT, NEPHU and our partners are currently undertaking sector and community level consultations to address the needs within priority population groups, helping to create culturally appropriate and sustainable program models that resonate with diverse communities in our catchment area.
NEPHU also works with partners to develop a shared language around addressing food systems challenges. By creating a collaborative understanding, we can help community stakeholders—such as local councils, schools, and health providers—find common ground to address barriers to healthy eating and support a united approach to investing in prevention for long term systems change.
Empowering youth and families as key change agents
We believe that young people play an essential role in creating and sustaining healthier food environments. Our initiatives aim to empower youth to participate in food environment solutions that directly impact their lives.
This focus on empowerment reflects NEPHU’s commitment to reducing stigma around obesity. By supporting adolescents in making healthy choices without fear of judgment, we are helping to shift perceptions of health responsibility from the individual to the community, creating a more supportive framework for healthy change.
The findings of Dr Carrello’s study provide powerful evidence of the financial benefits of investing in prevention. As rates of childhood obesity rise, the economic impact will only deepen unless comprehensive preventative measures are taken. NEPHU is committed to demonstrating the value of these investments and continuing to support policies that promote healthier environments.
