How tall a child will grow in the future is a concern of parents, especially those who are not very tall. They want to know as soon as possible how tall their children will grow in the future.
■ Current height prediction method
At present, the height prediction method is also called walker prediction method. This height prediction method is based on the child's current height, and uses the following formula to predict the child's future height: hm = a+b× c.
Hm in the formula is the height of the child in the future, A is a fixed value, B is the coefficient of the corresponding age, and C is the height of the child at that time. Due to the differences around the world, the error is 3 cm.
Facts have proved that this method of predicting children's height is basically suitable for China's national conditions. But for children who are precocious or late-maturing, the predicted value may be high or low.
■ Prediction method of foot length and height
03 ×7-year-old adult height = 65438+ foot length.
It is easier and more convenient to predict the future height of children with this method, and the error is less than 3 cm.
■ parental height prediction method
According to this principle, a European scientist created a formula for predicting height according to the relationship between the height of parents and the height of children:
How tall is the son? Cm =？ Father's height+mother's height × 1.08÷2
Daughter's height? Cm =？ Father's height ×0.923+ mother's height ÷2
This formula basically conforms to the genetic laws of "length is higher than height", "height with short" and "height with short". This formula is calculated according to the principle of genetics and the growth rate of European height.
In order to make this prediction formula more suitable for China's national conditions, China scientists "make foreign things serve China". According to the relationship between the height of Han children and their parents in Central China, the coefficient in the formula is changed to1.11.12 for men and 0.948 ~ 0.980 for women. Therefore,
Short children can grow longer.
For immature children, the body is still growing and developing, but the growth and development are very slow, giving people the illusion that they are no longer growing. However, there must be some reasons that hinder the growth and development of short and almost no longer growing children, such as insufficient secretion of growth hormone and thyroid diseases. As long as these diseases are cured, short children can continue to grow taller.
For short people who have grown up, as long as they are not too old, there are still ways to grow taller.
According to the law of bone growth and development, short people over 18 years old still have hope to grow taller before men are 25 years old and women are 2 1 year old.
As long as you take treatment such as taking growth hormone and stretching your bones, you can grow taller. It is best to take growth hormone under the guidance of a doctor, and the skeleton stretching of the body should also be carried out under the guidance of a doctor or physical education teacher who knows the law of human growth and development to achieve the best effect. In this way, most short young people can grow 2 ~ 5 cm tall, and some even reach as high as 7 cm.
There is also a scientific basis for growing taller.
■ Ensure a balanced diet
We should pay attention to the nutritional balance of our diet. The general principle of children's diet is to match coarse grains with flour and rice, animal protein with plant protein, and choose different vegetables and fruits according to the season to ensure that children get enough vitamins and minerals every day.
Generally speaking, we should consider adding more meat and eggs with high protein content to children's diet.
■ Develop good eating habits
The biggest bad eating habits of children are picky eaters and partial eclipse. Parents should not force their children to eat rudely, but should patiently guide them step by step. As long as you stick to it, you will gradually get rid of the bad eating habits of picky eaters and partial eclipse. If it is anorexia caused by digestive dysfunction, appropriate drugs should be used to regulate and strengthen the digestion and absorption function to prevent malnutrition and affect the growth and development of children.
■ Develop good work and rest habits
Children's adequate sleep time varies with age. Newborn babies need 18 ~ 20 hours, two to three months need 16 ~ 18 hours and five to nine months need 15 ~ 16 hours. When the baby reaches 1 year, it takes 14 ~ 15 hours and 9 ~ 13 years. /kloc-children over 0/3 usually sleep for 8 hours.
A good work and rest system is: eat when it is time to eat, study when it is time to study, try to relax when it is time to rest, and sleep when it is time to sleep. Only by forming a relatively fixed work and rest system can children grow and develop, thus growing into tall people.
