Factors that can't be changed
* Age: The older you get, the greater the likelihood that you will develop high blood pressure, especially systolic, as your arteries get stiffer. This is largely due to arteriosclerosis, or "hardening of the arteries."
* Race: African Americans have high blood pressure more often than whites. They develop high blood pressure at a younger age and develop more severe complications sooner.
* Socioeconomic status: High blood pressure is also more common among the less educated and lower socioeconomic groups. Residents of the southeastern United States, both whites and blacks, are more likely to have high blood pressure than Americans from other regions.
* Family history (heredity): The tendency to have high blood pressure appears to run in families.
* Gender: Generally men have a greater likelihood of developing high blood pressure than women. This likelihood varies according to age and among various ethnic groups
