Although it is now possible to bring
most high blood pressure under control, the causes of essential hypertension
remain elusive. Understanding how hypertension begins is at least partly a

before the 1970s, studies of the familial aggregation of blood pressure treated
only populations 15 years of age or older. Few studies were attempted in younger
persons because of a prevailing notion that blood pressures in this age group
were difficult to measure and unreliable and because essential hypertension was
widely regarded as a disease of adults.
