A three-day international conference on childhood obesity is due to get underway in Dublin later today.
More than 20 international experts, including speakers from the World Health Organisation, are due to attend the gathering.
They will be discussing recent advances in the prevention and treatment of obesity among children.
Ireland has one of the highest rates of childhood obesity in the world, with lifestyle factors and poor diet the main cause of the problem.
Studies have found that around one-quarter of all nine-year-olds in Ireland are overweight or obese.
