Remember the height of a parent, what is the formula for calculating the height of a child?

Parental height ** law.

According to this principle, a European scientist created a formula for height based on the relationship between the height of parents and the height of children:

The son is centimeters tall.

Father's height Mother's height.

The daughter is centimeters tall.

Father's height Mother's height.

This formula basically conforms to the genetic laws of "high plus tall makes tall", "short matches short and short", and "tall plus short makes tall". This formula is based on genetic principles and the rate of height growth in Europeans.

In order to make this formula more suitable for China's national conditions, China's scientific workers "use foreign for China", according to the relationship between the height of Han children and their parents in the central region of China, the coefficient in the formula is changed to between men and women, so that the calculated results are more in line with the actual situation of China.

When we were young, the teacher taught us to calculate the height of the child, which is used, the height plus the height of the mother, and then divided by two is the height of the child, we have been using this calculation formula to calculate the height of the child when we were in school, I don't know if this formula is still applicable now, the height of the father, plus the height of the mother, and then divide by two is the height of the child.

The girl's height = (father's height + mother's height -13) 2, error 5 cm, boy's height = (father's height + mother's height + 13) 2, error 5 cm, growth hormone plays the greatest role in the key factors of human body growth, in addition to nutrition, physical exercise, sleep, taste, etc. Children with normal development need good nutritional support, adequate sleep, fitness exercise, emotional stability, scientific disease prevention and other management, which can regulate the secretion of growth hormone and achieve the best growth of the body.

Boy's height = (father's height + mother's height + 13) 2, then add or subtract 5 cm. Girl's height = (father's height + mother's height 13) 2, then add or subtract 5 cm.

These formulas are based on statistical studies in different regions and different populations, so not everyone can fully meet these height formulas. And these formulas ignore the influence of factors other than genetics on the child's height, and are only suitable for making a very rough **.

It is normal for a child's height to fluctuate by 3-5 cm within the calculation formula, i.e. 5 cm above or below the height. Because the height of a child is not only related to the height of the parents, that is, genetic factors, but also closely related to nutritional status, regular work and rest, whether there is enough sleep, and whether they actively participate in physical activities.

Factors that affect height

A child's height is related to genetic factors and environmental factors, and the taller the parents, the taller the child. The growth and development have the following characteristics, the potato leak is about 50 cm when born, and the fastest growth in the first year, can grow 20-25 minutes. The growth formula for children aged 2-12 is 7+75 cm, and there are about two standard deviations above and below, which are considered normal.

The growth rate of the child should not be less than 5 cm every year, which needs to be tested by parents, and the child should not be short by looking at it. If you find that your child is growing very slowly, you need to take your child to the hospital for a check-up. Some parents don't pay enough attention to these things, but they delay the life of their children.

Boy's height = father's height + mother's height + 13's and 2;Girl's height = father's height + mother's height - 13's and 2.

For example, the height of the father is 1.8 meters, the height of the mother is 1.6 meters, the height of the father + the height of the mother + 13 = 353cm 2 =, so if it is a son, the standard height is. The baby's height is related to the height of the parents, and it is related to genetics, but the baby's height is also related to diet, environment and disease, so the height is ultimately determined by multiple factors. After the baby is born, it is necessary to pay attention to a balanced diet to meet the needs of growth and development.

According to the Report on the Status of Nutrition and Chronic Diseases in China (2020), the average height of men and women aged 18-44 in China is centimeters and 158 centimeters, respectively. In childhood and adolescence, measuring height 1-2 times a year is one of the important means to grasp the growth and development status in time. Normal height growth indicates good growth and development; If the growth of height is slow, basically not long, or even stops growing, it is necessary to analyze the cause and take corresponding measures to remedy it.

The influence of environmental factors on height

The environment includes the natural, social, and psychological environment. The environment also affects the growth and development of the human body to varying degrees, taking the climatic conditions of the natural environment and the influence of the geographical environment on height as an example in the basic factors of the environment.

After a survey conducted by the Institute of Pediatrics of the Chinese Academy of Sciences in 1975, the average height (cm) of the 17-year-old age group was analyzed: male, Beijing, Wuhan, Guangzhou; Female, Beijing, Wuhan, Guangzhou.

From 1982, China's research on the physical form, physiology and physical fitness of children and adolescents proved that children and adolescents aged 7-17 in Beijing were higher than those in the same age group in Hunan. The above two surveys have proved that although the height of children and adolescents in China is Han Chinese, there is a trend of high in the north and low in the south, which is not only related to food varieties, but also has a direct relationship with factors such as climate and environment, geographical location, and light time.
