CHILDREN from low income families are at higher risk of being overweight or obese than more advantaged children, according to new research.
A study by Melbourne's Murdoch Childrens Research Institute shows children from the most disadvantaged families are far more likely than others to become overweight and obese from the age of four to ten.
The researchers studied more than 4000 children from when they were four until they were ten or eleven as part of the Longitudinal Study of Australian Children.
The children were divided into five equal groups based on their socio-economic position, which takes into account family income and their parents' education and occupation.
Alarmingly, the socio-economic differences were already present in the body mass index (BMI) of children aged four and five, according to the a paper published in the journal PlosOne.
The study shows eight in ten children in the most advantaged neighbourhoods have a stable normal weight. This falls progressively to just over six in ten for the most disadvantaged neighbourhoods.
However, this study is not just about the most disadvantaged children, it is something that goes right across society, says lead researcher Professor Melissa Wake.
"When the obesity epidemic started to be reported among children in the late 1990s there was not a trajectory like this aligned to advantage and disadvantage. Now it has become very strong.
"Our paper does not answer why this has happened. There are many reasons. Probably they relate to the resources and healthy choices available to the most advantaged groups," she says.
"Clearly targeting children with early overweight and low socio-economic background must be a top intervention priority.
"However, this alone won't suffice. Vulnerability to unhealthy weight gain increases incrementally with each quintile further from the most advantaged.
"A whole lot of different approaches will be needed to solve the obesity problem. We need solutions that are focussed on the whole of society, not just one segment."
