Gather and Share Your Family Health History

If you are concerned about a disease running in your family, talk to your doctor in your next visit. A doctor can evaluate all of the risk factors that may affect your risk of some diseases, including family history, and can recommend you a course of action to reduce that risk.

Are you looking for a project to work on with your kids? Or planning to attend a family reunion this summer? If so, consider developing your family’s health history.

Family members share genes, behaviors, lifestyles, and environments, which together may influence their risk for developing chronic diseases. Most people have a family health history of common chronic diseases (e.g., cancer, heart disease, or diabetes) and other health conditions (e.g., high blood pressure and hypercholesterolemia). A person with a close relative affected by a chronic disease may have a higher risk of developing that disease than a person who doesn’t.

Americans know that family history is important to their health. One survey found that 96 percent of Americans believe that knowing their family history is important. Yet, the same survey found that only one-third of Americans have ever tried to gather and write down their family's health history. Are you ready to collect your family health history but don’t know where to start?

Make a list of relatives.
Write down the names of blood relatives you need to include in your history.

The most important relatives to talk to for your family history are your parents, your brothers and sisters, and your children.
Next should be grandparents, uncles and aunts, nieces and nephews, and any half-brothers or half-sisters.
It is also helpful to talk to great uncles and great aunts, as well as cousins.

Prepare your questions.
Among the questions to ask are:

Do you have any chronic illnesses, such as heart disease, high blood pressure or diabetes?
Have you had any other serious illnesses, such as cancer or stroke?
How old were you when you developed these illnesses?

Also ask questions about other relatives, both living and deceased, such as:

What is our family’s ancestry - what country did we come from?
What illnesses did our late grandparents have?
How old were they when they died?
What caused their deaths?

To organize the information in your family history you could use a free web-based tool such as My Family Health Portrait.

Family history can give you an idea of your risk for common diseases like cancer, heart disease and diabetes, but it is not the only risk factor. If you are concerned about a disease running in your family, talk to your doctor in your next visit. A doctor can evaluate all of the risk factors that may affect your risk of some diseases, including family history, and can recommend you a course of action to reduce that risk.
