Experts know that in adults younger than 65, having high cholesterol levels in your blood can raise your risk for heart attacks and strokes. However, in adults 80 years old and older, researchers have not—until now—thoroughly studied high cholesterol’s impact on heart disease, your ability to function well, or your risk for death.
In fact, some research shows that a higher level of total cholesterol and a lower level of so-called “bad” cholesterol (also known as “low-density lipoprotein” or LDL cholesterol) might be helpful in protecting your ability to perform daily activities and preserving your life for longer.
What’s more, it appears that having low cholesterol is linked to a higher risk of death from cancer, respiratory disease, and accidents in adults aged 80 and older. It also appears that the benefits of taking medications known as statins, which lower cholesterol, may lessen as people age. Researchers even have a phrase for this phenomenon. They call it the “risk factor paradox.” This describes the fact that for adults aged 80 and older, having some conditions that are considered health risks in younger adults predicts better survival. These conditions include having higher total cholesterol, higher blood pressure, and higher body mass index (BMI, a ratio of body weight to height that helps determine whether you are overweight or obese).
