Experts blame widespread obesity in U.S. children.
The new report from the CDC says only 14 percent of normal weight kids showed abnormal lipid levels, compared to 43 percent of obese kids.
As a result, the American Academy of Pediatrics now recommends cholesterol tests for overweight children.
Diet and exercise is also recommended, but in extreme cases, which are becoming more common, doctors may suggest treating young patients with statin drugs to lower cholesterol.
