As a pediatrician who looks at growth and development, I have seen too many cases where children miss the best time to grow because parents do not know some basic growth and development knowledge, which is a pity for them.
So, I summarized 30 knowledge points that parents must know about growing tall, and it is recommended to collect it first and then read it:
1. The height of children is "destined for seven points, three points rely on hard work", about 70% is inherited by parents, and about 30% is affected by factors such as the acquired environment.
2. The genetic height given by parents to their children can be estimated by two formulas: boy's height = (father's height + mother's height + 13cm) / 2±5cm; Girl's height = (father's height + mother's height 13cm) / 2±5cm.
3, acquired influencing factors include: nutrition, exercise, living habits, diseases, sleep, etc., although compared with 70% of genetic factors, it seems to be inconspicuous, but in fact, its actual impact is still great, after all, when the height is not tall enough, more than three or five centimeters is also undesirable, so the matter of growing taller is also love to fight to win.
4, exercise has a great impact on height, many surveys show that adolescents who often participate in sports are 4-7 cm taller than teenagers who rarely participate in sports, and even 10 cm taller, want children to grow taller, you can choose jogging, skipping rope, basketball, swimming and other aerobic exercises, to give children's bones a certain stimulation.
5, exercise want to help long people, the time can not be too long nor too short, too short ineffective, too long overload exercise, easy to cause cartilage damage, muscle strain, but not conducive to normal growth and development, can maintain about 30 minutes of moderate intensity exercise every day.
6. If you want to be tall and nutritious, we must ensure that children eat a balanced diet every day, pay attention to dietary diversity, and drink 250~500ml or equivalent dairy products every day.
7, balanced nutrition to grow taller, but overnutrition is not necessarily, if excess nutrition will cause obesity, obesity will increase the secretion of estrogen, let the epiphysis close in advance, estrogen secretion will also make sexual development advance, and the advance of sexual development will also lead to epiphysis early closure, resulting in height damage.
8, because growth hormone in the night after falling asleep will appear secretion increased, and related to sleep depth, so sleep will affect height, preschool children are best to fall asleep before 8:30 p.m., school-age children are best to fall asleep before 9 p.m., get up after 7 o'clock, try to avoid luminous sound at night, to ensure the child's good sleep quality.
9. In addition to going to bed early, we must also ensure the total amount of sleep of children every day, children aged 1 to 3 years old, to ensure 12-14 hours of sleep per day, children aged 3-6, not less than 12 hours of sleep per day, children aged 6 to 12, not less than 10 hours of sleep per day, children aged 12 to 18 years old, to ensure 8-9 hours of sleep per day.
10. Chronic diseases, long-term repeated infections, will consume energy, thereby affecting the growth rate, so when our children have symptoms, we should seek medical attention and timely treatment, and usually teach children to wash their hands correctly and other hygiene habits to reduce the impact of diseases on height.
11. Mood will also affect the growth rate, and children who have been in a high-pressure and depressive environment for a long time will also have an impact on height, so in order to maximize the genetic height of your child, please accompany your child more, criticize less, and communicate often.
Children from 12 and 3 years old to adolescence, the annual growth rate should be guaranteed 5-7cm, <5cm and >7cm are abnormal, need to go to the hospital in time to see a doctor.
13. If the child has not entered puberty, monitor the height at least once every six months, and if it enters the growth and development period of Kuaishou, it is recommended to measure the height once in 3 months, so that abnormalities can be detected in time and intervened in time.
14, measuring height is skillful, if the measurement is not standard, it is likely to get incorrect data, measure height, we have to use the same ruler at the same time (such as all morning, or are night), with the same ruler, the same person to measure, children to remove shoes and socks, heels, hips, back of the head close to the wall, girls to scatter their hair, and then use a triangular ruler or a thicker book, to ensure that the measuring tool and the wall have a vertical angle to measure height, each time to measure 3 times in a row, Then take the average data and record it.
15. A person's height is not constant throughout the day, because the spine will be compressed at the end of the day, and there will be a gap of 1-2cm between the height in the morning and at night.
16. Judge whether a child's height has reached the standard, do not compare with the children in the neighborhood, do not compare with the classmates, but with big data, what is big data, just now, from March 1 this year, the mainland began to implement the latest version of the "Growth Standards for Children Under 7 Years Old", children over 7 years old or according to the old standards, see the figure below:
17. What do you think of the form? First calculate the age of the child, pay attention to the age of one, find the column closest to the age of your child, in the comparison of your child's height, see which column it is, in the table, under 7 years old is expressed by percentiles, where P50 is the average height, the height between P25-P75 is normal, between P3-P25 is short, and <P3 is short. The table > 7 years old is expressed as standard deviation, where the median is the mean, and the range from -1SD to +1SD is normal, while -2SD to -1SD is normally short, and <-2SD is short.
18, if the height between P3-P25 belongs to the short or -2SD to -1SD of this part of the child, we must first see if his height is because the genetic height is only so tall, or because of some living habits problems, such as whether it is too fat, whether it does not like to exercise, whether it is lack of sleep, etc., you can improve the growth rate by correcting living habits.
19. If the height < P3, or <-2SD, these children who have reached the short index must go to the hospital for examination, because he is likely to have some endocrine diseases and need treatment.
20, to judge whether a child's height has reached the standard, there is also a very important indicator, that is, bone age, if your child's actual height does not match his years, but matches his bone age, then it means that your child's height potential is still there, but bone age can only judge the current height level, can not predict height.
21. It should be noted that if your child is taller than most of your peers, you should also be careful, this may be an illusion, most likely due to early development.
22, calcium tablets is a very important trace element for growing taller, but blind calcium supplementation can not help grow taller, if the growth is compared to building a house, then calcium is equivalent to bricks, bricks are enough, too much, there is not enough cement, no workers, the house can not be built, to ensure the intake of dairy products, soy products, fish and shrimp, eggs, most children do not need routine calcium supplementation, excessive calcium supplementation is easy to cause anorexia, constipation and even stones.
23, want to grow taller, vitamin D is essential, but for various reasons, children now generally lack sunlight, so we must supplement children with 400U of prevention every day.
24, girls before the age of 8 breast enlargement, before the age of 10 to menstruate, is precocious puberty, precocious puberty is not only harmful to health, but also affect height, so parents with girls should pay attention to their daughter's breast development, if you find that there are small bumps out, the age is wrong, remember to go to the hospital to see.
25. If the girl is fatter and has too much breast fat, it is not easy for parents to find out whether the breast has developed, and if the parents themselves are not sure, it is recommended to take it to the hospital to take a look.
26, girls menstruation, many parents will think that just began to enter the development period, the next will enter a long high-speed ball, in fact, no, menarche, represents the growth rate began to enter the downhill, according to statistics, girls after menarche, the average height can also grow 5cm, if this time is not satisfied with the height, hurry up to see a doctor, otherwise in half a year, there is no way.
27, the sign of boys entering puberty is the enlargement of testicles, not the long Adam's apple, long beard, voice change, etc. as everyone thinks, long Adam's apple, long beard, voice change individual differences comparison, but at least it suggests that the child has also entered the middle and late adolescence.
28, must have the idea of letting children grow taller by eating supplements, this is not worth the loss, because many supplements contain estrogen, which can lead to precocious puberty, and may find that children grow taller than other children in the early stage, but there is really a price, because of course, when other children begin to grow, your children will not grow, and eventually, they will be shorter than their peers.
29. Growth hormone can indeed help grow taller, but growth hormone cannot be used casually, and must reach certain indicators.
30, growing up is a long-term project, need parents to pay attention to it from time to time, if you can't figure it out, it is still recommended to go to the hospital for regular examination, such as regularly going to the hospital every winter and summer vacation, and save the data, in this way, there will generally be no big mistakes.
Well, the above is my growth and development clinic, parents are most concerned and most prone to make mistakes, which one you are most interested in, you can tell me in the comment area, I can write an article to talk to you in detail, or, what else do you want to know, you can also leave a message in the comment area.
