High cholesterol is considered an adult health issue, but a new study suggests that current screening guidelines for cholesterol in children miss many kids who already have higher cholesterol levels than they should. The study found that almost 10 percent of children who didn’t fit the current criteria for cholesterol screening already had elevated cholesterol levels. The current guidelines from the National Cholesterol Education Project recommend cholesterol screening for children with parents or grandparents who have a history of premature heart disease before age 55 or those whose parents have significantly elevated cholesterol levels (total cholesterol above 240mg/dL of blood). NCEP guidelines also recommend screening for children whose family history is unknown, particularly if they have other risk factors such as obesity. Experts are also suggesting that lifestyle is as important as heredity and that sedentary behavior and a diet full of high-calorie, fatty foods can also affect a child’s cholesterol and cardiovascular risk factors. If you have children, talk to your doctor about cholesterol screening.
