What is the value of high blood pressure by age group?

Hypertension values are 90 140 mm Hg and 60 90 mm Hg for diastolic blood pressure, regardless of age. It is recommended to eat more high-protein and vitamin-rich foods in the usual diet, pay attention to a low-salt and low-fat diet, do not smoke and drink, strengthen exercise, and control weight.

At present, the definition of hypertension in China is divided into two types: adults and minors. An adult is a person aged 18 years, and all adults have a definition of hypertension of 140 90 mmHg. In other words, in adults, regardless of age, hypertension can be diagnosed as long as the blood pressure reaches or exceeds 140 90mmHg.

The normal reference value of blood pressure for minors is determined according to different age groups, usually taking into account height and weight factors, and then setting the blood pressure range of the middle 95% of people in each age group as the normal reference value, if it exceeds this range, it is defined as hypertension. This can be found in the appendix of the 2018 edition of the Chinese Guidelines for the Prevention and Treatment of Hypertension. Using a simplified formula, it is also possible to preliminarily screen minors for possible abnormalities in blood pressure.

The formula is for boys: the normal systolic blood pressure is 100 + 2 * age, and the diastolic blood pressure normal value is 65 + age; Girls: normal systolic blood pressure is 100+ age, diastolic blood pressure normal is 65+ age.

The hypertension age comparison table that summarizes hypertension in the form of ** is as follows.

Blood pressure fluctuation refers to the degree of change in blood pressure within a certain period of time, which is one of the most basic physiological characteristics of human blood pressure. However, the standard of normal blood pressure is also different for different ages, such as the basal blood pressure of the elderly is not only at a high level, but also its fluctuation degree is relatively large. So what is the standard blood pressure value for each age group, see the figure below:

How high is blood pressure? According to the level of blood pressure, hypertension is generally divided into 3 grades, as shown in the table below (the former is systolic blood pressure, the latter is diastolic blood pressure):

In order to distinguish the different stages and severity of hypertension, in 1993, it was internationally stipulated that the damage of the heart, brain, kidneys and blood vessels should be staged according to the degree of damage (collectively known as "target sensitivity").

Stage: No organic lesions, no target organ damage.

Stage: Mild target organ damage, such as left ventricular hypertrophy, fundus arteriosclerosis grade, mild proteinuria, arteriosclerotic plaque found on ultrasound, etc.

Period: Obvious angina, stroke, renal failure, fundus hemorrhage, heart failure, etc.
