Older overweight kids take in fewer calories than their fit peers
In a new study, paediatrics researchers have found a surprising difference in the eating habits of overweight children between ages 9 and 17 years compared to those younger than 9.
Younger children who are overweight or obese consume more calories per day than their healthy weight peers. But among older overweight children the pattern is reversed – they actually consume fewer calories per day than their healthy weight peers.
"Children who are overweight tend to remain overweight," said Asheley Cockrell Skinner, lead author of the study from the University of North Carolina School of Medicine, said.
"So, for many children, obesity may begin by eating more in early childhood. Then as they get older, they continue to be obese without eating any more than their healthy weight peers.
"One reason this makes sense is because we know overweight children are less active than healthy weight kids. Additionally, this is in line with other research that obesity is not a simple matter of overweight people eating more — the body is complex in how it reacts to amount of food eaten and amount of activity," Skinner said.
These results also suggest that different strategies may be needed to help children in both age groups reach a healthy weight.
"It makes sense for early childhood interventions to focus specifically on caloric intake, while for those in later childhood or adolescence the focus should instead be on increasing physical activity, since overweight children tend to be less active," Skinner said.
