Kids and Cholesterol
● By Anonymous
Problems associated with high cholesterol generally don't show up for years, so making the connection between kids' health and cholesterol can be difficult. But it's important to know your child's cholesterol levels, especially if there's a family history of high cholesterol or premature heart disease.
Identifying high cholesterol now will let you and your doctor work together to make changes that will lower your child's risk of developing heart disease later.
About CholesterolCholesterol is a waxy substance produced by the liver. It's one of the lipids, or fats, the body makes and is used to form cell membranes and some hormones.
If you never ate another bowl of ice cream or another cheeseburger, your body would have enough cholesterol to run smoothly. That's because the liver makes enough for healthy body function. In fact, the liver produces about 1,000 milligrams of cholesterol a day. The rest comes from the foods we eat.
Although vegetables, fruits, and grains don't have any cholesterol, the following foods from animals do:
- egg yolks
- dairy products (including milk, cheese, and ice cream)
- Good vs. Bad Cholesterol
Two kinds — low-density lipoprotein (LDL) and high-density lipoprotein (HDL) — are the two most people have heard about.
Low-density lipoproteins, or "bad cholesterol," are the primary cholesterol carriers. If there's too much LDL in the bloodstream, it can build up on the walls of the arteries that lead to the heart and the brain. This buildup forms plaque — a thick, hard substance that can cause blood vessels to become stiffer, narrower, or blocked. Atherosclerosis is the name for hardening of the arteries. If a blood clot forms and blocks a narrowed artery, the result can be a heart attack or stroke.
Atherosclerosis can also diminish blood flow to other vital organs, including the intestines or kidneys.
High-density lipoproteins — the "good cholesterol" — carry cholesterol away from the arteries and back to the liver, where it's processed and sent out of the body, and might even help remove cholesterol from already formed plaques.
High levels of LDL increase the risk for heart disease and stroke. But high levels of HDL can help protect the circulatory system.
Three major factors contribute to high cholesterol levels:
- diet: a diet high in fats, particularly saturated and trans fats
- heredity: having parents or a parent with high cholesterol
- obesity: related to both diet and lack of exercise
Monitoring and Treating High CholesterolCurrent guidelines recommend screening in kids who are at risk for high cholesterol starting at age 2 but no later than age 10. Screening is recommended for kids who:
- have a parent with a total cholesterol higher than 240 mg/dL
- have a family history of cardiovascular disease prior to the age of 55 in men and 65 in women
- have an unknown family history
- are overweight or obese
- have additional risk factors, such as diabetes, high blood pressure, or cigarette smoking
According to the National Cholesterol Education Program (NCEP) guidelines for children and adolescents, the ranges of total and LDL cholesterol for kids 2 years to 18 years old are:
|Category||Total cholesterol (mg/dL)||LDL cholesterol, (mg/dL)|
|Acceptable||Less than 170||Less than 110|
|High||200 or greater||130 or greater|
Children with LDL cholesterol levels 170 mg/dL or greater should receive individual nutritional counseling that focuses on reducing dietary fat and cholesterol and increasing physical activity.
Kids whose results are acceptable should be screened every 3 to 5 years. Those with borderline cholesterol levels should be rechecked in 1 year.
Kids with high cholesterol levels should be rechecked after 3 to 6 months of lifestyle intervention.
Medication may be considered for kids over 8 years old with LDL cholesterol levels of 190 or higher if changes in diet and exercise haven't worked. For kids with additional risk factors, treatment may be considered at even lower levels.
10 Ways to Lower CholesterolHere are 10 ways to help keep your family's cholesterol at healthy levels:
- Know your own cholesterol level and if it's high, ask to have your kids checked.
- Serve a diet rich in fruit, vegetables, and whole grains.
- Choose lean meats and vegetable alternatives, including fish, legumes (dried beans, peas, and lentils), and tofu or other soy products.
- Read nutrition facts labels so that you can limit cholesterol and saturated and trans fat intake. The 2005 Dietary Guidelines and the American Heart Association (AHA) recommend keeping dietary fat intake between 30%-35% for kids 2-3 years old and between 25%-35% for kids 4 and older, with most fats coming from sources of unsaturated fats, such as fish, nuts, and vegetable oils.For kids older than 2 years and teens, the AHA recommends limiting: cholesterol to less than 300 milligrams a day; saturated fats to less than 7% of calories; trans fats to less than 1% of calories
- Choose nonfat or low-fat milk and dairy products.
- Stay away from solid fats. Use vegetable oil for cooking and soft margarine for table use.
- Limit beverages and foods with added sugars.
- Limit commercially prepared baked goods and serve healthy snacks such as fresh fruit, vegetables with low-fat dip, lite popcorn, and low-fat yogurt.
- Get plenty of exercise. Exercise helps boost HDL levels in the blood — and that's a good thing! Kids 2 years of age and older and teens should be physically active at least 60 minutes a day.
- Make living healthier a family affair. Kids usually aren't the only ones at risk, so it's important to make this a family effort. The strides you take to improve your family's lifestyle can have a positive effect on your family's health not only now, but far into the future.
