Researchers from the Centers for Disease Control examined five blood cholesterol levels of more than 16,000 U.S. children and teenagers over a 22 year period. The kids, ranging in age from six to 19 were part of the National Health and Nutrition Examination Survey.
Dr Brian Kit of the CDC says overall, the study showed improvements in the cholesterol levels of all age and ethnic groups, and in obese children, but the findings weren't all positive. Almost 1 in 10 of the children had elevated total cholesterol in 2007-2010. The study is in the Journal of the American Medical Association.
