Reasons for high normal blood pressure in children

Hypertension is common among the elderly, but it does not mean that children will not suffer from this disease. Many mothers are also surprised that their children have high blood pressure, which has a great impact on their children's lives, such as frequent dizziness. So what is the reason why children's blood pressure is higher than the normal value? Now let us analyze for you the high blood pressure in children.

(1) Genetics: According to relevant domestic and foreign statistics, the heritability of hypertension is between 60% and 80%, and the genetic effect becomes more obvious with age. The norepinephrine and dopamine concentrations of normal-blood-pressure children whose parents both suffered from essential hypertension were significantly higher than those of the corresponding control group with no family history of hypertension, indicating that essential hypertension may be associated with hereditary hypersympathetic function.

(2) Adolescents with Type A personality (Type A behavior is characterized by extreme competitiveness, a sense of time urgency, and being easily irritated or aggressive toward others) have a higher incidence of cardiovascular diseases than those with other types.

(3) Dietary sodium ions have a certain blood pressure-raising effect, and people who eat more fish are less likely to suffer from hypertension. Therefore, high-sodium diets should be restricted for high-risk groups, and they should be encouraged to eat more fish. Excessive salt intake in the diet can lead to high blood pressure, while high blood pressure rarely occurs when salt intake is less than 3g per day.

(4) Obesity: The accumulation of adipose tissue in obese people increases the capillary bed, causing an increase in circulating blood volume and cardiac output, which increases the burden on the heart and can easily lead to high blood pressure and cardiac hypertrophy over time. In addition, obese children with hypertension can lower their blood pressure by losing weight, which also proves that obesity has a significant impact on high blood pressure. Children's blood pressure is significantly positively correlated with weight, height and body mass index, among which weight is the most obvious.

(5) Exercise: Studies on young athletes have shown that physical exercise increases cardiac output, slows heart rate, and consumes excess calories, thereby effectively controlling the formation and development of risk factors related to cardiovascular and cerebrovascular diseases such as obesity, hyperlipidemia, and poor cardiovascular adaptability, and provides a good foundation for the early prevention of cardiovascular and cerebrovascular diseases in adults.

(6) There are differences in the prevalence among other races, with African Americans having more cases than Caucasians. In addition, long-term mental stress, excessive sympathetic nerve excitability, lack of sleep, smoking, etc. can also increase blood pressure due to excessive production of adrenaline and norepinephrine in the body.

Above we talked about the reasons why the normal blood pressure values ​​in children are higher, but it is worth noting that the blood pressure of children of different ages is also different. You should consult your doctor for specific circumstances. In the past, it was rare for children's blood pressure to be above normal. This year, more and more children's blood pressure is above normal. Mothers should pay more attention to and reflect on this, and must pay attention to their children's diet and exercise.
