The future height is predictable.
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 make your body 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.
■ How to grow taller?
Whether the height is satisfactory depends on several factors. First, genetic factors, accounting for 70%, and other conditions, including sports, nutrition, environment and social factors. In order to make children grow taller, parents should pay attention to the following points:
First, don't miss the rapid growth period.
During the development of children and adolescents, when is the height the fastest? Studies have confirmed that the height of most Han children in China is about 12 years for girls and 14 years for boys. More than 90% of the girls are between 1 1- 13 years old and the boys are between 13- 15 years old. In order to make children grow taller, parents should pay special attention to their nutrition and exercise during the rapid growth period.
Second, we should pay attention to nutritional supplements.
Nutrition is the key to children's physical growth. The energy, protein and amino acids needed for normal growth of the body must be provided by food, mainly meat, eggs, beans and beans. Bone formation also requires sufficient calcium, phosphorus and trace amounts of manganese and iron. Insufficient calcium intake and vitamin D deficiency will lead to insufficient bone mineralization, vitamin A deficiency will make bones shorter and thicker, and vitamin C deficiency will make bone cells brittle and affect bone growth.
At present, the average family should have a comprehensive and adequate nutrition and a balanced diet. Parents should be careful not to let their children develop the habit of partial eclipse, let alone let their children eat too many snacks, which will affect the intake of important nutrients.
Third, don't neglect physical exercise.
Physical exercise can strengthen the metabolic process of human body, accelerate blood circulation, promote the secretion of growth hormone, accelerate the growth of bone tissue, and be beneficial to human body length. The following kinds of exercises have a certain effect on height growth, so try them.
1.？ The hanging swing adopts horizontal bar or door frame, and the height should be that the body is hung on the bar and the toes can just leave the ground. Hold the lever with both hands, the distance is slightly larger than the shoulder width, the feet are close together, and then the body swings back and forth, not too much, not too long. It is best to arrange exercise every morning and try to relax and droop for 20 seconds. Young men should do 10 ~ 15 times, and young women should do it 2 ~ 6 times.
2.？ When jumping to touch the height, touch the preset object with both hands, which can be branches on the roadside, basketball baskets or ceilings. Jump with your feet and do it 30 times. Take a rest and jump with your left foot and right foot, as above.
3.？ When playing basketball in ball games, actively strive for rebounds and jump shots to break the ball; Try to jump up when playing volleyball, and do more smash and block; Practice jumping up and hitting the ball on the forehead in football.
4.？ Jumping exercises can do one-leg jump, frog jump, triple jump, multi-stage jump and vertical jump in situ.
Fourth, don't forget to create a good living environment for children.
Abnormal mental nervous system will also affect children's physical development. If parents divorce, the relationship between children and guardians is abnormal, children are often abused, or children are seriously stimulated, their growth rate will gradually slow down, making their height lower than the lower limit of normal children of the same age and gender. Being short will aggravate a child's sense of inferiority, which is due to the psychological and social stimulation to the child, which affects the transmission of nerve impulses from the cerebral cortex to the hypothalamus, thus inhibiting the secretion of growth hormone by the pituitary gland. When the child's environment is handled, the growth rate can return to normal.
5. Don't forget to actively prevent and treat chronic diseases.
Children and adolescents should be actively treated for chronic diseases. Chronic infection, chronic hepatitis, chronic nephritis, asthma, heart disease, anemia and other long-term diseases will affect growth and development. Genetic diseases of bones, such as osteochondral dysplasia, can also limit the growth of bones.
How to make children grow tall and strong?
"mom! Because of you, I was born so short. " Jia Xiang, a junior high school student, has been sitting in the front row since elementary school. Seeing that her height was getting worse than that of other students, she complained angrily to her mother.
"Who told you not to drink more milk? You don't exercise at ordinary times!" Mother answered him grumpily.
When children grow up, parents care not only about their health, but also about whether their children will grow tall and strong in the future. Pediatric clinics and online health consultation websites often see parents anxiously asking, "Doctor, why is my child not tall?" "Drink more milk to help? Some impatient parents even inquire about the prescription of "increasing height" everywhere, hoping that their children will grow a few centimeters taller.
However, some people think that people's height is determined by genes, and nutrition and exercise have little effect.
How tall a person can grow is born, or do you have to work hard the day after tomorrow
What can a developing child do to have a chance to get ahead?
Judging growth rate from bone age
People gradually grow taller in the process of growth, which is the result of bone growth and development, mainly manifested in the growth of lower limb bones and vertebrae.
The growth of lower limb bone is formed by the growth plates of femur and tibia. Growth plates are located at both ends of the bone. Stimulated by the growth hormone secreted by pituitary gland, they will constantly proliferate cartilage, and the new cartilage will become hard bone after calcification, so the bone will become longer and wider.
From birth to 1 year-old, the child grows fastest in his life, and then the speed gradually slows down. Until adolescence, sex hormones begin to interact with growth hormone, and the child's height and weight begin to increase sharply.
Wang Zhihong, an attending physician in orthopedics at National Taiwan University Hospital, pointed out that the progress of a person's height should be evaluated together with the "bone age" (the age of bone growth and development), not just by the average age. Some precocious children, the progress of bone age is faster than the actual age, and their height is more prominent than that of their peers at the beginning, but it is not necessarily that adults will grow taller later.
How long our height can grow depends on the closure of the whole body growth plate. If the growth plate is closed, it means that the bone has matured, the bone no longer grows, and the height will not increase.
What factors will affect a person's height?
Heredity determines your height.
The most important factor that determines a child's height is heredity.
Wang Zhihong, an attending orthopedic physician at National Taiwan University Hospital, said: "The correlation between parents' height and children's height is as high as 80%, and the influence of parents is half." Therefore, if the parents are not tall, the height of the child is generally not particularly prominent.
However, there are exceptions. Mr. Yang, who works in a construction company, is only 160cm tall and his wife is not tall. However, both his sons have broken the genetic restriction. One is over 180cm in height and the other is over 170cm in height. Friends joked that this is the masterpiece of Yang's "genetic mutation".
For this special situation, Li Junxian, a pediatrician at Guangxin Hospital, pointed out that a person's height is not determined by a single specific gene. Most people have both high genes and short genes. Whether it is tall or short depends mainly on which one is expressed by genes. "So in a family, sometimes one child is tall and the other child is short," Li Junxian explained.
However, doctors believe that the height gap between parents and children is more than ten centimeters, which is purely a minority. Most children are still similar to their parents when they grow up.
Seeing this, many short parents may be disappointed. Since genes decide everything, can the efforts of the day after tomorrow help?
In fact, in addition to genes affecting height, other related factors can not be ignored. "Suppose your genes decide that you can grow to 160 cm, but your malnutrition and lack of exercise probably won't make you grow to this height," said Li Junxian, who thinks that the efforts the day after tomorrow are equally important.
Nutrition and exercise can help you grow taller.
Human growth is a comprehensive performance. In addition to genetic limitations, the following factors will also affect the child's future height:
Nutrient intake
Adequate and balanced nutrition is absolutely the key to the success of children's growth.
According to the recommendation of the US Food and Drug Administration (FDA), indispensable nutrients include protein, calcium, vitamin A, vitamin C, vitamin D, minerals magnesium and zinc.
Protein is the basic substance that constitutes and repairs human muscles, bones and tissues. Lack of protein can lead to skeletal and muscular stunting and atrophy. Animal foods such as meat, seafood and milk are completely protein sources, while plant sources can be obtained from beans, grains and stone fruits.
Calcium is a raw material for making bones, which can promote growth and increase bone density. Therefore, drinking two cups of milk every day is a good way for children to accumulate bones.
Vitamin D is another nutrient that makes bones strong. In addition to milk, salmon, tuna and other fish, the human body can also make vitamin D by sunbathing 10 ~ 15 minutes every day.
Mineral zinc is an indispensable nutrient for infant development. Dutch studies have found that insufficient zinc intake during infant development can lead to developmental retardation. In addition, according to many foreign studies, children's intake of sufficient zinc can reduce the incidence of diarrhea. Foods rich in zinc include meat, liver, seafood (especially oysters), eggs and wheat germ.
"Iron is also important for growth and development," added Weng Huiling, a nutritionist at National Taiwan University Hospital. However, according to the national nutrition survey conducted by the Ministry of Health, iron deficiency is common among women over 4 years old in China, while the iron deficiency rate is higher among men in adolescence and over 65 years old. So growing children should eat lean meat, animal liver, egg yolk or dark green vegetables to get enough iron.
take exercise
Many people think that jumping, such as skipping rope and playing basketball, is helpful to grow taller, which is true from a medical point of view.
According to the research, it is found that excessive compression of the growth plate will cause growth retardation, but moderate and intermittent compression or stretching of the growth plate can stimulate its growth.
Therefore, children and teenagers who want to grow taller have to do sports, especially some bouncing sports. However, excessive weight training such as gymnastics and weightlifting will hinder growth, and doctors suggest that it is best to avoid it during the growth stage.
Hormone secretion
The secretion of many hormones in the human body dominates or affects our growth and development, such as growth hormone, sex hormone, thyroxine, parathyroid hormone, insulin and so on.
sleep
As mentioned earlier, human growth is mainly influenced by growth hormone, which is secreted especially vigorously at night, so if you want to grow taller, don't stay up at the expense of sleep time, and try to sleep before 1 1 pm.
disease
Congenital diseases such as heart, kidney, lung and liver, bone diseases, endocrine and metabolic diseases, Turner syndrome and other chromosomal abnormalities will all affect normal growth and development.
Except for a few people who are short stature due to family genetic factors, if they are malnourished, they can make up for it by supplementing nutrition, but if they are abnormal growth caused by diseases, they should seek medical advice as soon as possible.
Many parents are worried about how to judge whether their children's growth and development are normal, and sometimes they even worry too much, forcing their children to eat hard, or asking about the secret of "growing taller".
Doctors suggest that parents can evaluate their children's growth from two aspects:
Measure your height once every six months.
Under normal circumstances, children will grow at least 5 ~ 6 cm tall every year before puberty. If the child is less than 4 cm in one year, parents should take the child to pediatrics and ask a doctor to evaluate it to further understand the causes of growth retardation.
Refer to the growth curve in Children's Health Handbook.
If the child's height is lower than the third percentile of the same age group, it is regarded as pathological short stature and needs examination and treatment. However, parents should not be too happy when their children are superior. If the growth curve exceeds the 97th percentile of the same age group, it may be abnormal and must be checked and confirmed.
psychologic factor
Excessive stress will cause endocrine dysfunction in human body, resulting in insufficient secretion of growth hormone and limited growth. In addition, too much pressure can also cause gastrointestinal dysfunction. Children not only have a bad appetite, but also have poor absorption ability. In the long run, it will lead to malnutrition and it is very difficult to grow taller.
The secret of being tall and strong.
Although genetic restriction makes us "resigned", both doctors and nutritionists believe that the most effective way to "do our best" is to start with diet and cooperate with regular exercise.
It is not difficult for parents to make their children grow tall and strong as long as they master a few dietary secrets.
Observe the principle of balanced diet.
Children, like adults, should eat six kinds of food every day. Parents can refer to the daily dietary guidelines of the Department of Health to understand the dietary needs of children of different ages. (see table)
Adolescent children grow up quickly and their activities increase. In order to provide energy and nutrition for growth and development, the demand for heat is relatively high. Boys need to consume 2150 ~ 2,650 calories a day, and girls need 2100 ~ 2,200 calories.
Parents lead by example, not partial eclipse.
Many studies have pointed out that children's eating habits from childhood are most influenced by their parents. Weng Huiling, a nutritionist at National Taiwan University Hospital, believes that if children want to grow well, it is the most basic principle not to be partial to food. Parents should change as much as possible when matching their children with three meals, so that children can try all kinds of food from an early age. Eat a variety of foods, so don't worry about the lack of nutrients needed for growth.
Don't make negative comments about food in front of children.
For example, "Bitter gourd is so bitter, do you dare to eat it? A casual remark by an adult will make a child establish a specific impression on a specific food, which will later become an excuse for him to refuse to eat. Of course, don't use food as a tool to reward or punish children.
Teach children a balanced diet.
Most meals in modern dual-income families are eaten out, and many parents give their children money to buy their own lunch. Nutritionist Weng Huiling suggested that parents should pay more attention to their children's eating out, instill some healthy eating concepts in their children, such as eating less fried and fried things, choosing balanced and diverse dishes, and ingesting all six foods. "Parents can't control their children's diet, which will easily lead to malnutrition in the long run," she stressed.
Avoid making children fat or dieting to lose weight.
Li Junxian, a pediatrician at Guangxin Hospital, pointed out that the bone age of obese children progresses faster than their actual age because they consume too much calories, fat and sugar. Although their height is higher than other children from the beginning, they may not grow tall in the future because their growth period is compressed in advance.
In fact, it is very simple to prevent children from getting fat. As long as they limit the number of high-calorie foods such as hamburgers and French fries, drink less sugary drinks and exercise regularly, there will be no obesity problem.
In addition, nutritionist Weng Huiling believes that modern young girls are influenced by the slim figure of idol stars. Even if their weight is normal, they still go on a diet to lose weight, which not only misses the opportunity of growth and development, but also seriously affects their health as adults.
The golden time of growth and development is fleeting. If you want your child to grow tall and strong, seize the opportunity to practice Professor Jian Kang's "secret recipe for increasing height".
Exercise is indispensable for bone growth.
Children's growth is inseparable from moderate exercise. Children who don't exercise enough have no appetite during the day and can't sleep at night. As a result, I was sleepy in the morning and wanted to sleep, but I couldn't sleep at night. Go to class without breakfast in the morning, feel groggy for a day, and obviously have insufficient exercise during the day.
Exercise itself can promote the secretion of growth hormone. It can make people fall asleep, and you know it can promote the secretion of growth hormone. After full exercise, you can increase your appetite and sleep at night. In the morning, I can wake up naturally, have a good breakfast and start a new day with a good attitude.
What kind of exercise is beneficial?
What kind of exercise should I do in order to grow taller? It is often heard that some children join the school basketball club in order to grow taller. Can they grow taller after playing?
Simply put, exercise that can increase appetite, promote sleep, and give certain longitudinal pressure to bones is beneficial to height. There are jogging, skipping rope, dancing, playing basketball and volleyball. But many children in basketball and volleyball players are already very tall. If you let children who don't like these sports engage in these sports just to grow taller, you are wrong. Because emotional stability is also important for growing taller, let children choose their favorite sports. But for high school students who have stopped growing, it is better to engage in strenuous exercise that consumes too much physical strength. The development of bones comes from longitudinal pressure to some extent, but the pressure is too high (weightlifting, etc. ) makes it difficult for bones to grow vertically.
The exercise that helps to grow taller is not conducive to the exercise that grows taller.
Also choose children's favorite sports: volleyball, basketball, ballet, stretching gymnastics, skipping rope and jogging.
It is not good to force children to do sports they don't like: weightlifting, excessive exercise, and sports that consume too much (marathon, etc.). ).
How can you grow taller if you are short?
Short teenagers, except for short stature caused by some diseases, must be treated carefully by doctors, and most of them must rely on their own efforts to tap their growth potential. How to dig? In short, under the guidance of doctors and sports workers, we should adjust our diet and lifestyle and adhere to special physical exercise.
Regarding the adjustment of diet and lifestyle, there are the following suggestions for reference:
1. Adjust the diet reasonably, avoid partial eclipse and overeating, ensure adequate nutrition and control moderately. Do not smoke or drink;
2. Life should be regular, sleep should be adequate and regular, and it is best to sleep on a hard bed with a pillow less than 5 cm;
3. Pay attention to self-care, prevent diseases before they occur, and treat diseases early. Read books about short stature and growth and development of height. If you don't understand, you can consult a doctor to increase your knowledge and use science to guide your actions.
4. Maintain physical and mental health, enrich entertainment life, be emotionally stable and have no worries, which is conducive to growth and development.
In recent years, it has been reported by the author that moderate physical exercise lasting 1-2 hours can obviously increase the content of body wind growth hormone in a certain period of time. With the increase of growth hormone content in blood, the tubular bone growth area will live and fall, thus increasing the height.
Should be taken into account, whether it is a small amount of exercise (such as jogging, slow swimming and so on. ) or sports with a large amount of exercise (such as marathon running and long-distance skiing). ) will not increase the height, the former is due to insufficient stimulation, and the latter is extremely weak because of it (such as completing 1000 jumps and excessive weight lifting exercises in one day, and even hindering the growth of long bones). Success depends on the correct combination of different exercises.
Some scholars believe that long-term jumping, hanging weights, swimming and other activities can really promote height increase. We believe that all short children and adolescents who can't cope with epiphysis should bravely start special physical training to increase their height if doctors think that they don't suffer from short diseases and have no other medical contraindications. However, it is worth mentioning that the training should be gradual, especially at the beginning, don't overdo it because of impatience, pay attention to your own self-feeling, and consult doctors and physical education teachers if you feel uncomfortable.
Help you grow tall and straight.
Warm-up exercise: move the joints of limbs, keep your back straight, lean forward, straighten your arms, and swing back and forth forcefully.
Walking: swing your arms violently and push forward.
Run: run in small steps, while putting your fists on your shoulders and rotating your arms in front of your elbows; Run and jump 25-50 meters quickly, repeat 4-6 times, and rest after each time.
