Considering 115/75 mmHg a normal BP for an adolescent corresponding to his/her age, height and sex nevertheless, a consistent linear upward trend of this BP level forms the basis of adult HTN a leading cause of high cardiovascular, nervous system and kidney related morbidity and mortality.
Meta-analysis of more than 61 prospective studies from 1 million adults, showed that the risk of cardiovascular disease increased beginning at systolic BP levels less than 115 mmHg and diastolic BP levels less than 75 mmHg. Evidence based exiting data published for both pediatrics and adults, has projected a graded association between increased blood pressure (BP) and risk of cardiovascular disease, end-stage renal disease, along with mortality. Globally, hypertension (HTN) is found to be major risk factor accounting for 10.2 million deaths and 208 million disability adjusted life years. Blood pressure (BP), is the pressure of the blood exerted on the arterial walls, produced by the contraction of the left ventricle against the resistance offered by arteries and arterioles that is required for the optimal body functioning, however, persistent high blood pressure (hypertension) is a global health issue.
