High cholesterol

How common is high cholesterol?

High cholesterol is very common.

About half of all American adults have a cholesterol level that's higher than recommended.

Total cholesterol levels that are more than 200 milligrams per deciliter (abbreviated as mg/dL) are considered to be unhealthy. (Your total cholesterol count is the combination of levels of good high-density lipoprotein (HDL) cholesterol and bad low-density lipoprotein (LDL) cholesterol in your blood.)

Of all the American adults with high cholesterol, 1 in 7 has a cholesterol level that puts them at risk of getting heart disease (that is, their total cholesterol is higher than 240 mg/dL).

The research also tells us that:

After the age of 50, more women have high cholesterol than men. One theory about this is that the rise in cholesterol among older women may be caused by a drop in levels of the hormone estrogen in their bodies. Estrogen is the main female sex hormone. Estrogen is thought to help keep cholesterol down.
White Americans and Mexican-Americans are most likely to have high cholesterol, while American Indians are least likely to have high cholesterol. Black Americans and Japanese-Americans fall in the middle. Researchers are not sure why this is, but it may be due either to differences in genes (the basic units in the body's cells that control how they grow and behave) or in people's diets.
Children can also have high cholesterol.

⁷ One big study found that the average American child has a total cholesterol count of 165 mg/dL. That's just under the level considered to be heading toward unhealthy for children (which is 170 mg/dL).

² Because the average is high, it suggests that many children in the United States have unhealthy cholesterol levels, although it's not possible to say precisely how many there are.
