Although humans still can't understand the secret of heredity, heredity has "absolute right" in height. The family genetic history of children is 1 among the factors affecting their adult height. Take a look at the parents' height and figure, and evaluate the child's growth and development, and you can probably know his adult height.
Key factor 2. Children's precocity affects their height
If the child is precocious, parents should find out early and take the child to a regular hospital for specialist treatment as soon as possible. During the summer vacation, the number of outpatients in the adolescent growth and development center of Ruijin Hospital has more than tripled. Professor Wang Defen, director of the center, said that the living standard is improving day by day, and urban children are developing at an earlier age. If the bone age is too early, it will affect the child's final height, so parents should be reminded. It is reported that most of the outpatients in the adolescent growth and development center of Ruijin Hospital are precocious puberty. When the reporter interviewed in the center, a mother came to see a doctor with her 9-year-old daughter. The mother said that when her daughter was 8 years old, her breasts began to develop.
After that, my daughter went to Ruijin Hospital at menarche. Results The doctor found that the bone age of the girl was 13 years old. According to the doctor's analysis, the time of seeing a doctor was delayed by one year, and the bone age increased by far more than one in this year.
At the age of 20, the height of girls will not exceed 10 cm. Therefore, the 9-year-old child is now 140 cm, and it is unlikely that the final height will exceed 150 cm.
Key factor 3. Diet and nutrition affect height.
Two key elements: health and comprehensiveness.
The importance of nutrition is beyond doubt. If a child does not get a comprehensive and balanced nutrition supply during his growth, in other words, if his food intake is unhealthy and incomplete, then he will not get normal growth and development.
In fact, it is very difficult to do this, because parents can't make standard nutrition recipes for their children like nutritionists, but it should be noted that parents should at least be healthy when providing food for their children.
The problem usually exposed is that parents restrict their children's food intake in order not to make their children "chubby" (no matter how fat their babies are, they should not restrict their diet). Also, too much fruit juice or carbonated drinks will interfere with the child's appetite, thus reducing his absorption of nutrients.
Key factor 4. Lack of core nutrition affects children's height.
If children in China are shorter than those in Japan, people probably won't believe it. However, the researchers' statistics show that the average height of 7-year-old boys and girls in China is 0.6 cm and 0.5 cm shorter than their Japanese peers, and the average height of boys and girls aged 15 ~ 18 is 0.6 cm shorter than their Japanese peers.
What is the reason for this difference? Only one-third of the factors that determine height are genetic genes, and two-thirds are acquired environmental conditions. In acquired conditions, lysine, zinc, calcium and other core nutrients are the most critical.
Yes According to the China Adult Physical Fitness Monitoring Report released by the State Sports General Administration (formerly the State Sports Commission) 1998, the average height of men over 40 in China is higher than that of Japanese men of the same age 1.2 cm, and men under 39.
It is 0.68 cm lower than that of Japanese men of the same age, and the height advantage of China people over 40 years old is a thing of the past. The results of the fourth national nutrition survey show that the intake of core nutrients such as lysine, zinc and calcium among children in China is seriously insufficient.
Feet.
According to the nutrition survey published by the Ministry of Health in 2004, the average daily calcium intake of China people is only 4 1% of the daily requirement, with a deficit of 59%, especially for children. A large number of domestic
The investigation report of zinc deficiency in children shows that; The zinc deficiency rate of infants aged 1 year is as high as 93.90%, that of infants aged 1-2 is 86.70%, that of infants aged 2-4 is 72.90%, and that of infants aged 4-7 is 34.60%. Lysine is the first ammonia lacking.
Basic acid, there are 22 kinds of amino acids in human body, of which 8 kinds of amino acids can not be synthesized by human body, but can only be obtained from food, which becomes deficient amino acids, and among these 8 kinds of deficient amino acids, lysine is the least in food.
Therefore, it is the first amino acid lacking. It is urgent to supplement children with core nutrition!
Key factor 5. Core nutrition participates in children's growth.
Lysine is an effective promoter of growth hormone secretion.
A large number of experiments at home and abroad have proved that adequate lysine supplementation can stimulate the pituitary gland to increase the secretion of growth hormone. These studies have also identified biomolecular indicators related to bone growth, such as ALP (bone alkaline phosphatase),
IGF- 1 (insulin-like growth factor), TGF-B (transfer growth factor), OC (osteocalcin), NO (nitric oxide), etc.
Under the action of lysine, the active factors produced and secreted by bone cells increased obviously. It shows that lysine can activate the proliferation of bone cells and stimulate their functional activity.
Key factor 6. Zinc directly participates in DNA replication.
The study on zinc's participation in DNA replication shows that under the condition of zinc deficiency, the speed of DNA replication is obviously slowed down and the amount of DNA synthesis is also obviously reduced, thus slowing down or stopping cell division. The elucidation of this cellular and molecular mechanism of zinc finally reveals the secret why zinc deficiency will lead to growth and development stagnation.
There is about 1300g of calcium in human body, of which 99% exists in bones and teeth. Therefore, calcium is not only the main functional component of bones and teeth, but also the storage of calcium in human body. Bone can be hard and straight, which is inseparable from the biomineralization of calcium. It is conceivable that calcium-deficient bones become soft and deformed, and the growth of children is impossible.
Key factor 7. The reproductive age of parents affects the height of children.
Studies have pointed out that a person's height is determined by many factors. For example, the number of children at home and the order in which children are born will all affect the height of children.
Parents' educational level and work also affect children's height. For example, the average height of children born to parents who are engaged in strong mental work is higher than that of descendants of manual workers. For example, the process of urbanization also indirectly affects children's height.
For example, children in cities mature early and their physical fitness is better than that in rural areas, and the improvement of nutritional environment is one of the important factors. In addition, the age of parents at the time of giving birth will also affect the height of children.
Key factor 8. Staying up late will affect the height of children.
In recent years, a large number of investigations and studies have confirmed that the amount of auxin secreted by short children is far less than that of normal children, and a considerable number of children are caused by lack of sleep at night. Because children grow up.
In the early stage of sleep, the secretion of auxin is strong, and the secretion from 9: 00 pm to 9: 00 am the next day is three times that of daytime 12 hour, especially 70 minutes after falling asleep at 9: 00 pm, a secretion peak can appear. have
In view of this, children should not stay up late.
Key factor 9. Physiological conditions: at the same time, be careful of the side effects of drugs.
Some children are born with some serious physiological diseases, which will hinder their growth and development if they are not treated in time. The most common are: gastrointestinal diseases, such as abdominal diseases; Food allergy; Thyroid problems; hormone
Insufficient secretion; Heart, kidney or liver diseases; Or some kind of chromosomal abnormality. In addition, we should also pay attention to the side effects of some drugs in the treatment of diseases, which will also hinder development, such as stimulants such as ritalin.
In the process of treating ADHD, it is found that drugs have an impact on development. Therefore, if you need to take special drugs, you must carefully choose the prescription and dosage.
The key factor 10, children's lack of maternal love affects their height.
Some experts have found that emotional disorders can also affect height. If a child grows up in an environment lacking family warmth and can't get enough maternal love, then his height is often shorter than that of his peers. In foreign countries, such short people are called emotional dwarfism, and some data call it "love breakdown syndrome".
The reason of short stature caused by emotional interruption is that the function of hypothalamus and pituitary system is suppressed by emotion, which leads to the decrease of pituitary growth hormone secretion. In addition to their short height, these children also have abnormal behaviors such as late mental development, excessive drinking, overeating, one-man show, hyperactivity, and uncoordinated interpersonal relationships.
Children with emotional interruption are generally restless and insecure, and sometimes they wake up and cry, which will affect the quality of sleep. And children's growth hormone-hormone is only divided during deep sleep and deep sleep.
The secretion is strong, so the secretion of this growth hormone may be greatly inhibited in children who are restless and easy to wake up, which is one of the important reasons why children are not tall.
