Problem description:
I am 14 years old and my height is 1.64 meters. How can I be taller? (There was a period of rapid rise in Grade One)
It's grade three now. I didn't fall asleep until 23: 30 because I had to go to school (at night 1 1: 30).
How can I grow taller faster? Skipping rope? Or what food to eat in the morning, noon and evening (don't say what heightening drugs or therapeutic devices to use)
Analysis:
The child is tall and learned.

Moderator: Hello, audience friends! This is CCTV's live program "The Road to Health". Today we will talk about the development of teenagers.
Narrator: Xiao Hao and Xiao Fei are classmates in the same school. Every day, they walk into the campus hand in hand. They are all 1 1 years old and have almost the same hobbies, but the biggest difference is their height. As soon as I enter the teacher, the two good partners will be separated. Because of my figure, Xiao Hao was arranged in the first row, and Xiao Fei had to sit at the end.
Moderator: Why is there such a big difference in height between children of the same age?
Lin Wansheng: There is a great difference in height between individuals. One of these differences is related to genetic factors and the other is related to environmental factors.
Factors affecting height growth
1, genetic factors
2. Environmental factors
Nutrition; Physical exercise; sleep
Emotion; health condition
Moderator: What are the differences between these factors?
Lin Wansheng: According to the research of geneticists, genetic factors account for a large proportion in height, and more than 70% of height is determined by genetic factors.
Lin Xiaoming: Acquired factors can also affect height growth through nutrition and exercise. One of the most important factors is nutrition. For example, a very important nutrient in a child's diet is the intake of heat energy and protein. In addition, for example, calcium is the most important trace element affecting children's height, because the growth of height elements is mainly the growth of bones, and calcium mainly provides raw materials for bone growth in the process of bone growth. Zinc is extremely important in children's growth and development, because it participates in some key enzymes in protein synthesis, so zinc-deficient dwarfs are often common.
Lin Wansheng: Genetic factors indicate the potential to reach a certain height, but it is environmental factors that ultimately determine whether to reach a certain height. As can be seen from the figure, from 1955 to 2000, the height of men in Beijing is increasing.
Moderator: Let's look at a reporter's investigation:
Grandma: It should be at least 1.65 meters long, so that children can move more easily.
Grandma: Genetic factors also have something to do with it.
Grandma: You can't lose him, or it will affect his growth.
Grandpa: It doesn't matter what nutrition you eat. The key is diet regulation.
Grandpa: Respect children's hobbies, make children feel happy, and the family provides a good environment.
Grandma: I think it should be seven minutes full. Our children never have cotton-padded clothes.
Grandpa: Children need more protein. Eat more seafood such as fish and shrimp and drink more milk.
Lin Xiaoming: Besides heredity, environmental factors also play a very important role. The increase in height in recent years is mainly due to good living conditions. Children's physical exercise is gradually increasing, which is very important for improving living conditions and is conducive to children's growth. In addition, sleep is also very important for children, because the endocrine in a state of adequate sleep is often active, and some growth hormones secreted are also beneficial to children's growth.
Moderator: Some parents think that children should be given seven points full. Is this correct?
Lin Yusheng: I think children should be fed, because adequate nutrition can provide children with a material foundation for growth.
Moderator: Let's watch a short film:
Narrator: The height of human body is the growth of the whole body, but the most prominent thing is the length of limbs, especially the growth of lower limbs. Experts believe that the key to human height lies in the growth of long bones. Epiphysis at both ends of long bones are closely related to the growth of bones. The ossification of cartilage continues in epiphysis and bone plate, and the ossification in bone is prolonged, which makes the long axis of bone grow and people grow taller. Once the epiphyseal ossification is completed, the epiphyseal plate and epiphysis are completely integrated with the spine, forming an epiphyseal line, and people can never grow taller again. The sudden increase in human height has two periods. One is the growth period. From birth to one year old, the body length increases by 20-25 cm, about half of the body length at birth, while the body weight increases by 6-7 kg, about twice the body weight at birth. In the second year, the height can be increased by 10 cm, and the weight can be increased by 3 kg. Since then, the growth rate has dropped sharply and maintained a relatively balanced growth. The second period of sudden increase starts from adolescence, and girls generally start from 9- 1 1 year old, two years earlier than boys. The height of adolescence increases by 6-8 cm every year, and a few people can reach 10- 12 cm, forming the second growth peak. After puberty, the bones are completely calcified and the height stops growing.
Lin Xiaoming: If we pay attention to children's growth environment in two critical growth periods, it will be beneficial to children's growth, especially in the second growth peak period, so that children's smooth growth will not be affected.
Moderator: First of all, what preparations should be made before and after birth to help children grow taller?
Lin Xiaoming: First of all, it is very important that the mother's nutrition is very important for the growth of the fetus, especially in the second and third trimester of pregnancy, the child's body grows rapidly, which lays a very important height foundation for the child. Specifically, from pregnancy 13 to 40 weeks, the child's height grows rapidly. If the mother takes in enough nutrition, it is beneficial to the growth of the child. During this period, mothers should eat enough whole grains (staple food), and it is also important for mothers to grow normally during pregnancy.
Dietary guide during pregnancy
Ensure adequate energy from the fourth month of pregnancy.
1 to ensure normal weight gain in the third trimester.
2. Increase the intake of fish, meat, milk and eggs.
Moderator: Now there are more and more reports about the so-called giant baby. Why?
Lin Xiaoming: This often happens in cities, usually because pregnant women eat too much food during pregnancy, which makes their children grow too fast. If the weight gain can be controlled within 0.5 kg per week in the middle and late stages, the possibility of this situation for children will be less.
Moderator: What problems should we pay attention to in adolescence?
Lin Yusheng: One is reasonable nutrition, which must be done. Of course, reasonable nutrition does not mean that the more the better. The second point is to strengthen physical exercise. The third point is adequate sleep.
Adolescent growth factor
Reasonable nutrition
Strengthen physical exercise
adequate sleep
good mood
Ensure health
Moderator: Can you use growth hormone to help children grow taller?
Lin Wansheng: Auxin is a very important hormone for children's growth. No problem. If there is a lack of growth hormone, the height growth of children will be affected. Of course, the use of growth hormone has certain indications and cannot be abused casually. How to use it is up to the doctor. For most short children, growth hormone is not the main goal.
Moderator: So what nutrition should I eat? How to ingest?
Lin Xiaoming: A Reasonable Diet for Teenagers
1, 400-600g grain
2. Fish, meat and poultry150-175g
3. 50-75g of eggs and 250g of milk or soybean milk.
4.50 grams of soybeans or bean products (dried beans)
5. Vegetable 300-500g, fruit 50-100g.
6. Edible oil 10-20g, sugar 10g.
Lin Yusheng: There are also some pathological problems that affect height. For example, children with various acute and chronic diseases, such as chronic nephritis, are generally not as tall as other children, and frequent colds will also affect their height growth. In addition, long-term malnutrition, especially insufficient supply of calories and protein, will also affect height. Another endocrine disease, mainly pituitary dwarfism, the pituitary gland secretes growth hormone. If this growth hormone is secreted too little, it will affect the growth of children. Of course, to make this judgment, you need to go to the relevant hospital to do relevant growth hormone tests. If you really lack growth hormone, you can consider using growth hormone, which takes a long time to inject. Moreover, the use of growth hormone has certain timeliness. If the child's epiphysis has basically healed, it is useless to use growth hormone again.
Moderator: Beijing Cao 15 years old. I like exercising. Is there any specific exercise method that is good for growth?
Lin Xiaoming: Now children should do more moderate-intensity aerobic exercise, such as jogging, playing ball, swimming and table tennis. In addition, children are not suitable for strenuous exercise, such as weightlifting and strength exercise, which is not conducive to children's growth.
Moderator: Let's look at a group of helpful exercise methods:
Narrator: This method can be used anytime and anywhere, and it is very simple. Stretching on your back: Lie on your back on the mat, bend your arms on your chest, cross your index fingers, straighten your lower limbs, inhale and stretch your arms to the top of your head, at the same time straighten your toes, stretch your body as much as possible, exhale gently, relax and recover your body. Exercise frequency 10-25 times depends on age. Push-ups: Push-ups on both hands, then tuck in your abdomen and legs, keep your upper body still, straighten your legs and push one leg back. Leg wheel movement: lie on your back on the bed, keep your legs turning back and forth like pedaling a bicycle, and change the speed from time to time for 2-3 minutes. Here are some ways to promote outdoor sports. The first way is to touch the height and try to touch the place where the body can't reach. The other is in-situ long jump, with arms as wide as possible. There is also skipping rope, try to keep jumping twice a second, about one minute 120 times, and stick to it for 3-5 minutes. You must keep doing these exercises.
