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.
Hypertension is classified as either primary (essential) hypertension or secondary hypertension. About 90â95% of cases are categorized as primary hypertension, defined as high blood pressure with no obvious underlying cause.idney disease is the most common secondary cause of hypertension. Hypertension can also be caused by endocrine conditions, such as Cushing's syndrome, hyperthyroidism, hypothyroidism, acromegaly, Conn's syndrome or hyperaldosteronism, hyperparathyroidism and pheochromocytoma.
