Is the height prediction method accurate?

Height prediction is a way for many people to predict the baby's height. Usually when a woman is pregnant, mom and dad will predict how tall the baby can grow according to her height. Because height is a method to predict the amount of accidents, the result may not be accurate for everyone, so is the height prediction method accurate?

Is the height prediction accurate? It is to use the height of children and adolescents in a certain period to predict the future final height, or to compare the heights of two periods to get the final height. Guidance: This method has certain reliability and is widely used in height prediction. This method is divided into primary prediction method and secondary prediction method. The hospital can predict the height according to bone age, bone density and epiphysis, but there is a certain error with the real height. Pay attention to a balanced diet, eat more foods rich in protein and vitamins, take more sunshine to supplement calcium, and strengthen physical exercise, all of which will contribute to the growth of height.

The height of human body is generally predicted by the height of parents and the growth and development of bones in early childhood. Using the formula of parents' height, we can roughly calculate the future height range of children. Generally, the height of a male is equal to the sum of the height of his parents multiplied by 1.08 and then divided by two. This value is the height of a boy through heredity, while the height of a woman is generally the height of her father multiplied by 0.923, plus the sum of her mother's heights divided by 2, and the result is roughly that women get it through heredity. Children before the age of seven can also predict their height by detecting bone age and judging the gap between growth and development and actual standards. Children with older bones may be taller and children with younger bones may be shorter.

Adolescence is an important period of adolescent physical development. There are many factors that affect their height. On the one hand, it is related to genetic factors, on the other hand, it is also influenced by acquired factors, such as endocrine factors and sex hormones. In addition, adequate sleep, balanced nutrition and moderate exercise all contribute to their height growth. Generally, the height of boys grows rapidly at the age of 15- 16, and stops growing at the age of 20-24. There are many factors that affect height, such as heredity, nutrition, exercise, environment, living habits, nationality, endocrine, sexual maturity and so on. According to your age, you can scientifically predict whether there is room for growth and intervene when necessary. Then pay attention to strengthen nutrition, ensure adequate sleep, and often jump rope, touch the heights, swim and other jumping sports.

What should I do if my child grows slowly? First of all, slow growth and short height are two different situations. The growth of children's height is slow, which may be because the growth and development period of children is slightly delayed than that of ordinary people. In this case, parents don't need to worry. It is recommended to supplement calcium, have a good sleep and a good life, which is beneficial and harmless. At the same time, it is necessary to strengthen physical exercise and do more jumping exercises, which will help the bones to stretch up and down and promote their height. Let the baby go outdoors and bask in the sun naturally in the game. Through the single glass, the ultraviolet rays of direct sunlight are reduced by 60%, and only 20% of the ultraviolet rays pass through the double glass. The indoor ultraviolet ray 4 meters away from the window is only 2% of the outdoor ultraviolet ray. Suggestion: Infants who are cold outdoors in the north and not suitable for sunbathing can be properly supplemented with cod liver oil.

Sleep is the guarantee factor of growth and development, because the growth hormone that promotes human growth is mainly produced during sleep, and the released growth hormone has the highest secretion level at night, and the secretion amount during sleep is three times or more than that during waking state, so ensuring adequate sleep is conducive to growth, muscle relaxation and joint and bone stretching during sleep. Exercise can increase appetite, ensure sleep quality, promote blood circulation, increase the blood supply of bone tissue, and make bones grow vigorously.

Accurately measure the baby's height at the same time and in the same environment every year. The measurement conditions are: after getting up in the morning, don't wear shoes and socks, don't wear a hat, let the baby hold his chest high, his shoulders droop naturally, and his toes are slightly apart. Make a table of height measurement data every year. Generally, the curve of children's height is rising. If the growth rate of infants under 3 years old is less than 7 cm/year, the growth rate from 3 years old to adolescence is less than 4 ~ 5 cm/year, and the growth rate of adolescence is less than 5.5 ~ 6.5 cm/year, it can be inferred that infants are stunted.
