Australia launches decade-long study to combat child obesity crisis

A major new study will track 60,000 Australian children over a decade to tackle rising obesity and poor health. Researchers warn that without action, today’s youth could face shorter lives and serious medical problems. The project, starting in 2027, will focus on diet, exercise, sleep, and heart health from early childhood onwards. Current figures show around 30% of Australian children are overweight or obese. Experts predict this could climb to 50% in the coming decades. Poor sleep and lack of activity are key factors driving the crisis.

Health professionals advise simple changes to improve children’s sleep: setting bedtimes before 9pm, cutting out caffeine, and removing screens from bedrooms. Meanwhile, one trial will test weight loss drugs for overweight parents, aiming to improve their health and set better habits at home.

The study will also introduce regular blood pressure checks in schools. Researchers estimate that, in every classroom, at least one child already has high blood pressure—a condition that raises the risk of heart attacks by midlife. Professor Melissa Wake from Murdoch Children’s Research Institute stressed the urgency, warning that many children may not outlive their parents without intervention.

Trials will be rolled out in stages, targeting different age groups across childhood. The goal is to gather long-term data and develop practical solutions before health trends worsen. The 10-year study aims to provide clear evidence on how to reverse declining child health. If successful, its findings could shape school policies, family routines, and medical guidelines. Without changes, researchers say the next generation faces higher rates of disease and a lower life expectancy than today’s adults.
