How tall a person can grow, genetics is one of the main factors, accounting for about 60-70%, the other 30-40% also depends on the efforts of nature, which can also explain some of the following phenomena, some parents genetic height is very good, but children grow short, some parents genetic height is not good, but children grow very tall, some twins or siblings height difference is very much.
When parents find that their children are 2 standard deviations shorter, about 8-300px, compared to children of the same age and gender, or that girls have enlarged breasts by age 8 and boys have enlarged testicles by age 9, they need to find the cause and should promptly visit a growth and development specialist, who will determine whether your child is normal and needs to be treated. This will require a series of tests, such as a bone age determination is mandatory.
Bone age, or the age at which bones develop, can be determined through x-rays to see what stage of growth and development a child is at. The combination of age, skeletal age, and simultaneous height measurements can be used to predict a child’s final height. In the case of “precocious puberty”, the onset of puberty is early, and the age of the bones is significantly earlier, resulting in early closure of the epiphysis.
Growth is throughout childhood, there are two growth spurts, from birth to 2 weeks of age, the first peak, these two years can grow more than 30 cm tall, so this period of feeding and nutritional status is the key to determine the growth. After this to puberty, we will maintain the growth rate of about 5, 6 cm per year. Adolescence is the second key period of our life scampering, puberty development boys generally in 12-14 years old, girls about 10-12 years old, when the height of a breeze up, is the speed of 10 cm a year, if puberty significantly earlier, the space for growth is significantly reduced. Therefore, parents should pay attention to children’s growth and development throughout the whole period, especially whether puberty is early, from childhood, timely detection of problems, early consultation, early intervention can achieve a more ideal height.
Among the acquired factors, growth hormone, exercise and nutrition are the main factors affecting height.
The secretion of growth hormone plays a very important role in height. Insufficient secretion of growth hormone inevitably leads to short stature, and if timely medical consultation and treatment are not provided, it will lead to a significantly shorter adult stature, which will be less than 140 cm, the so-called “dwarfism”. The secretion characteristics of growth hormone fluctuate greatly during the day and night, and the number and magnitude of secretion at night are greater, so for children during the growth period, it is recommended to go to bed before 10:00 and get 8-10 hours of sleep.
Generally speaking, the sisters who live in the exact same environment, the one who loves sports will be a little taller. The one who loves sports is 5 cm taller than her sister. But the sports that help to grow taller here, especially refers to vertical sports. For example, jump rope, basketball, volleyball, badminton, swimming and so on. “For elementary school students, playing basketball and other skillful sports is not very suitable, the most convenient is indoor jumping rope. Now many children jump rope in order to jump fast, each jump range is very small – toes from the ground will not exceed 2 cm, so jump no effect. It is recommended that children do not take the rope, empty-handed jumping, feet from the ground about 10 cm, and each time to jump enough 30 to 40 minutes, in order to stimulate the growth of the long bone plate, the effect of growth will be more ideal.
More exercise, early to bed, look quite easy, many of the elementary school students who came to the clinic had poorly said, can not do ah, too much homework, to do ten eleven, no time to exercise, no opportunity to go to bed early. So schools and parents should reduce the amount of homework, to improve the efficiency and speed of learning, take some time for children to exercise, which is conducive to improving physical fitness and help to grow taller.
As for the nutritional status, there are certain misunderstandings in the feeding of children nowadays, picky, partial food, too fine, unbalanced nutrition or too many supplements, resulting in short, thin, precocious or obese children, to correct these bad eating habits, emphasizing meat and vegetables, reasonable nutrition: 1. Too heavy school bags will affect the height of children.
Seek the truth: If it is a shoulder bag, due to uneven body force, easy to have a negative impact on the spine, thus affecting the growth of height. But replaced by ordinary shoulder bags, as long as not too early excessive weight, generally will not affect the spine. This excessive, refers to some rural children seven or eight years old to pick dozens of pounds of burden. School bags 5 to 10 pounds, will not have a significant impact on height.
2, eat more nutrients can increase height.
Seek the truth: adequate nutrition can indeed promote growth, especially food containing more protein, but everything must not be excessive. Nowadays, parents are not poor, found their own children’s head is small, they prepare sea cucumber, turtle and other food, the result is counterproductive, if the child’s spleen and stomach function is weak, poor appetite, too much protein is not conducive to absorption, will cause excessive burden on gastrointestinal function, causing vomiting, diarrhea, etc.. For obese children, excessive appetite and excess nutrition lead to obesity. And like honey, ginseng, placenta, bird’s nest and other nutritional products, because they contain hormones, will trigger precocious sexual maturity, but also lead to premature closure of the child’s bone age, later will not grow taller.
The more high grade and nutritious you eat, the better your child will grow.
3. After the epiphysis closes, there is still the possibility of growing taller.
The truth: some children with closed epiphyses are still eating the so-called nutritional products recommended by some businesses to promote growth, which is complete nonsense. After the epiphysis is closed, it is impossible to grow taller. Therefore, many parents wait until they find out that their children are not growing before they come to the doctor, or they have had a checkup and then they don’t follow up because it was normal. The bone age is too old, there is little room for growth, the treatment effect is very poor, and the parents regret it.
In general, children’s height and sexual development problems should be closely monitored from the age of 6, with regular checkups every six months, specialist evaluation and early guidance.
