A chemical that was once widely used in plastic may be linked to an increased risk for childhood obesity.
BPA is a chemical that was once used in plastic materials like baby bottles, cups and food packaging.
In recent years, it has been phased out of many products.
Researchers measured levels of BPA in the urine of children before measuring their body fat and waist circumference.
They found the higher the level of BPA, the higher the risk for obesity.
However, experts say the study does not prove BPA causes body fat.
