World Obesity Day is celebrated annually on 4 March, and this year the global health community will unite to raise awareness of the numerous root causes of obesity. The day is celebrated under the theme "8 billion reasons to act on obesity".

This year’s campaign highlights the urgent need for prevention, early detection, and comprehensive treatment strategies that can shape healthier futures for every individual on the planet.

Globally, more than 1 billion people are living with obesity, including 159 million children, with projections suggesting that by 2035, half of the world’s population could be affected.

Obesity is classified by the World Health Organisation as a chronic, relapsing disease arising from complex interactions between genetics, neurobiology, eating behaviours, access to a healthy diet, market forces, and the broader environment.

“Recognising obesity as a chronic medical condition shifts the focus from blame to treatment, helping people feel safe to seek care and support,” said Heart and Stroke Foundation SA dietician Cari Erasmus.

“Obesity is influenced by genetics, environment, and biology; it’s not just about personal choices, and society needs to understand this. Early intervention is critical; identifying those at risk and supporting them with healthy habits can prevent long-term health complications.”

Addressing obesity requires society-wide action, including reducing stigma, improving healthcare access, and creating supportive environments for everyone, she said.

The Heart and Stroke Foundation SA, in partnership with the national department of health, promotes a three-pillar strategy to tackle obesity: creating healthier environments, protecting those at risk through early screenings, and providing lifelong support and guidance.

Erasmus notes that parents and schools play a crucial role in establishing healthy habits in children, from modelling nutritious eating to involving children in meal preparation and maintaining distraction-free mealtimes.

“What children learn about nutrition and movement today lays the foundation for their lifelong health. Early habits truly matter. Involving children in meal preparation and teaching them to make healthy choices empowers them to take control of their own well-being.”

Erasmus said tackling obesity requires a collective effort that combines healthier environments, supportive communities, evidence-based treatments, and education.
