Family Health History

Family members share genes, behaviors, lifestyles, and environments that together may influence their health and their risk of chronic disease. Most people have a family health history of some chronic diseases (e.g., cancer, coronary heart disease, and diabetes) and health conditions (e.g., high blood pressure and hypercholesterolemia). People who have a close family member with a chronic disease may have a higher risk of developing that disease than those without such a family member.

Family health history is a written or graphic record of the diseases and health conditions present in your family. A useful family health history shows three generations of your biological relatives, the age at diagnosis, and the age and cause of death of deceased family members. Family health history is a useful tool for understanding health risks and preventing disease in individuals and their close relatives.

Some people may know a lot about their family health history or only a little. It is helpful to talk with family members about your health history, write this information down, and update it from time to time. This way family members will have organized and accurate information ready to share with their health care provider. Family health history information may help health care providers determine which tests and screenings are recommended to help family members know their health risk.

To help individuals collect and organize their family history information, CDC’s Office of Public Health Genomics collaborated with the U.S. Surgeon General and other federal agencies to develop a Web-based tool called “My Family Health Portrait.”
