Hypertension is currently generally divided into hypertension in adults and hypertension in minors.1 Hypertension in minors is generally calculated in the age range of 3-17 years, the age group. The simplified formula standard for hypertension screening is: boys, systolic blood pressure higher than 100 + 2 times age, diastolic blood pressure higher than 65 + age. For girls, systolic blood pressure is higher than 100 + 1.5 times age, diastolic blood pressure is higher than 65 + age. 2, adult hypertension refers to hypertension at the age of 18 and above, and the diagnostic criteria are three measurements of blood pressure on different days, systolic blood pressure greater than or equal to 140 mmHg and or diastolic blood pressure greater than or equal to 90 mmHg. Any diagnosis of hypertension, as long as one of the systolic and diastolic blood pressure reaches the standard Any diagnosis of hypertension can be made if either systolic or diastolic blood pressure meets the criteria.
