Obesity declines among rich US teens, rises in poor
WASHINGTON (AFP) - In the past decade, obesity has declined among US teenagers from rich families but has risen among their impoverished counterparts, a gap driven by lack of exercise, said a study on Monday.
The research by experts at Harvard University examined what appeared to be an encouraging decline in adolescent obesity and found that only the upper class is benefiting.
"We find that although the overall obesity prevalence has plateaued, the trend looks very different across different subgroups," said the study in the Proceedings of the National Academy of Sciences.
Using family income as well as the education level of the parents to analyse two major US surveys, researchers found a growing class gap where obesity was concerned.
