Kids and Cholesterol: Keeping Cholesterol Under Control
High cholesterol is a health problem we often associate with adults, but children can also be affected. High cholesterol levels, along with other factors that put adults at risk for heart problems ( high blood pressure, diabetes, lack of physical activity, being overweight or obese, and smoking), also put children at risk later in life.
For instance, high cholesterol levels play a role in forming fatty plaque build-up in arteries, causing the arteries to harden. This condition, known as atherosclerosis, can start in childhood. If not addressed, it can lead to coronary artery disease in adulthood.
Should My Child Be Screened?
The National Heart, Lung, and Blood Institute (NHLBI) recommends that all children have a cholesterol screening when they are between the ages of nine and 11 years old. However, if high cholesterol levels run in your family or if your child has certain risk factors, he or she may need cholesterol screening before then. Discuss this with your child's doctor. All children should be checked again between the ages of 17-21 years.
There are two types of cholesterol often discussed: “good” cholesterol, also known as HDL cholesterol, and “bad” cholesterol, also called LDL cholesterol. LDL cholesterol is the main culprit of heart problems, so keeping levels low is important. For children, this means making sure that their LDL cholesterol level is less than 110 mg/dL (milligrams per deciliter). Here are cholesterol level guidelines from NHLBI:
LDL Cholesterol Levels in Children and Teens 2-19 Years Old
Total Cholesterol Levels in Children and Teens 2-19 Years Old
Children older than eight years old who have very high LDL cholesterol levels, usually 190 mg/dL or greater, may be given medicines called statins. Statins work by lowering cholesterol levels in the blood. A doctor may prescribe this medicine to your child if she has been diagnosed with familial hypercholesterolemia (an inherited condition in which a person is born with high levels of LDL cholesterol) and diet and exercise have not lowered the cholesterol levels enough.
Healthy Lifestyle Tips
Regardless of your child’s cholesterol levels, a proper diet and exercise are important to keep cholesterol levels under control, as well as maintain overall health. Here are some ways to incorporate a nutritious diet and physical activity into your child’s life:
Children will often look to adults as lifestyle examples. Therefore, to encourage healthy habits, it is important that the entire family is involved in eating right and exercising. Doing so will ensure that both you and your children can lead healthy lives together.
