Overview

About high cholesterol

A child can have high cholesterol because of their genetics or their lifestyle habits. Your child may have a higher risk if they:

  • Have a family history of high cholesterol or early history of heart attacks or strokes

  • Eat a lot of processed foods or snack foods, fast food or sugary beverages

  • Do not get much physical activity

All children should have their cholesterol checked between ages 9-11. This test can be done by your child’s pediatrician during a Well Child visit.

What is cholesterol?

Cholesterol is a waxy substance that floats in our blood. It helps make things like vitamins and hormones, but in too high amounts can lead to heart disease, like heart attacks or strokes.

  • LDL is the bad cholesterol (think “L" for "lousy”)

  • HDL is the good cholesterol (“H” for "happy”)

  • Triglycerides are a fatty substance in the blood that floats with cholesterol.

LDL levels should be less than 110 mg/dL. HDL should be above 45 mg/dL. Triglycerides vary based on a child’s age and whether they fast before the test. For fasting tests, triglycerides should be less than 90 for children ages 10 and older and less than 75 for children 9 and under.

If you have a family history of high cholesterol or early heart attacks or strokes, your doctor may order a lipoprotein (a) test. Lipoprotein (a) is attached to the LDL cholesterol and if it is high, makes the LDL extra “sticky.” Having high lipoprotein (a) – even with a normal LDL – can increase the risk of heart attack and stroke.

Treatments

Healthy habits

Treatment for high cholesterol first focuses on making healthy lifestyle choices, including diet and exercise.

Healthy eating

All children can benefit from these healthy eating tips:

  • Increase fruits and vegetables and decrease processed foods as much as possible

  • Increase fiber with more whole grains, beans, broccoli, spinach or carrots

  • Use olive oil or canola oil instead of butter

  • Avoid sugary drinks like juice, soda or sports drinks

  • Save bakery products for special occasions

  • Grill or bake foods instead of frying them

  • Replace french fries at restaurants with a fruit or vegetable for a side

  • Eat chicken and fish more often and limit red meat consumption (such as beef)

  • Drink skim or 1% milk (chocolate milk should be a treat)

  • Drink water all throughout the day (50-60 ounces of water per day)

  • Eat meals together as a family

Activity

It can seem like kids have endless energy sometimes but they don’t always get the amount of exercise they need. The goal is for one or more hours of activity per day.

For kids who may not be active on a regular basis, start small and aim for just 10 minutes a day. Once you start to make it a habit, you can increase the amount of time until you reach that one-hour goal.

Activity ideas

Great ways to get children moving include:

  • Walking

  • Hiking

  • Swimming

  • Running

  • Jumping rope

  • Games of tag

  • Dancing

Get the whole family involved with activities such as an after-dinner walk or weekend hike in a local park.

Limit screen time to less than 2 hours per day (this includes TV, tablets, computers, and video games).

For more ideas, check out local health clubs like the YMCA or community recreation leagues for organized opportunities like swimming lessons or team sports such as soccer or basketball.

When medications might be used

In children with really high cholesterol that doesn’t change with lifestyle changes or a strong family history of early heart disease, a statin medication may be used.
