Primary hypertension (with an unknown cause) is the most common cause of high blood pressure in adolescents and adults, but is less common in children. Many children with high blood pressure also have adult relatives with hypertension, indicating there may be a hereditary aspect to the disease. There is a higher incidence of high blood pressure in African-American children after the age of 12 and into adulthood.
Secondary hypertension. Secondary hypertension (or, less commonly, inessential hypertension) is a type of hypertension which by definition is caused by an identifiable underlying secondary cause. It is much less common than the other type, called essential hypertension, affecting only 5% of hypertensive patients. It has many different causes including endocrine diseases, kidney diseases, and tumors. It also can be a side effect of many medications.
