"According to the Report on the Nutrition and Chronic Disease Status of Chinese Residents (2020), the average height of adult males aged 18 to 44 in China is 169.7 cm, and that of women is 158 cm, an increase of 1.2 cm and 0.8 cm respectively compared with 2015."
In today's society, competition is fierce, and sometimes a little more advantage than others may be a little more opportunity. For example, in the workplace, people with higher height have a better chance of being admitted to some companies that pay attention to image, and they have a better chance of finding another half with excellent conditions. So even if it is a child, parents hope that they can have tallers and find a job in the future without worrying.
In such a situation, the height of children has become the focus of many parents' concern.
How tall is the child to be normal? Measuring bone age is key
Xuan Xuan's father is 1 meter 74 tall, and his mother is 1 meter 58 tall, which is not too tall, so the husband and wife are worried that if they pass on their genes to Xuan Xuan, Xuan Xuan will not even have 1 meter 7, if he is a boy who is less than 1 meter 7, he may encounter a lot of trouble in the future, so Xuan Xuan's parents are very worried about this and have thought of many ways.
Xuanxuan's mother bought growth-promoting health products for her children from the Internet, and then 7-year-old Xuanxuan's height increased by 8 centimeters in one year, and indeed grew a lot taller, and his parents were very happy. But then, the parents found that Xuan Xuan began to have symptoms of precocious puberty, so the two quickly took Xuan Xuan to the hospital for examination.
The doctor took Xuan Xuan to a bone age test, and the results were measured that Xuan Xuan's bone age was 2 years older than the actual age, and the height and bone age did not match, which meant that Xuan Xuan was precocious, and if he did not intervene in time, the follow-up may not even grow 1 meter 7.
Popular science, biological age (bone age) minus the age of life, if the difference obtained is greater than 1 year old, it represents precocious puberty, if it is less than one year old, it is backward development.
Bone age can reflect a child's growth and development, and a larger bone age means that it stops developing faster than others. Xuan Xuan is now 2 years older than his bones, so he may stop developing 2 years earlier, and when he calculates it, it is estimated that he will be 6 to 10 centimeters younger than the average child, so as the doctor said, he may not even grow 1 meter 7.
If you want to know whether your child's height is normal, the most objective criterion is to measure bone age, general growth and development clinics or pediatric endocrinology can be measured, and the ionizing radiation used to measure bone age is harmless to the human body, so there is no need to worry.
Here is another height table for you, you can compare it to see if the height is standard.
Many parents will make some wrong moves for their children to grow up, and here is also a list for everyone, hoping not to "step on the thunder".
For the healthy development of children, there are 2 common misunderstandings for parents to avoid
The first one is what Xuanxuan's parents just did, casually giving their children growth hormone. Now many merchants are selling height anxiety, so that parents buy a variety of health care products for their children to eat, promote growth and development, do not know that this is "seedlings to promote growth". If this causes the child's epiphyseal line to close early, it will be difficult to grow taller in the follow-up, and it will be shorter at that time.
Second, feeding the child into a fat child, thinking that if you give the child more food and more nutrition, the child will grow taller, which is a big mistake. Childhood obesity will not only compress bones, affect hormone secretion, lead to precocious puberty, but also may induce fatty liver, diabetes, these are real cases, so parents do not take it for granted, the child's physical health is the first condition to promote development.
In order to avoid obesity, parents usually need to strengthen the management of children's diet, the intake of rice, greasy food and high-sugar foods should be moderated, so that children eat less snacks and supplement fruits and vegetables. In addition, let the child get excited, do not always hide at home, to go out to exercise more, exercise can not only lose weight, but also promote bone, muscle strength, help grow tall.
Finally, a reminder that the height of the child, in fact, a large part of the genetics is related, so sometimes parents can not be too embarrassed about the child, if the parents are not high, the child is difficult to grow into Yao Ming, rather than tangling with height, it is better to care more about the child's physical health and mental health, so that the child has a happier childhood.
In general, whether the child's height is in line with age, bone age measurement is the most accurate, if the gap is more than one year, it should be paid attention to, may be precocious or late puberty. Parents usually care about the height of their children, do not use the wrong method, only with physical health as the first criterion, in order to let the child develop healthily.
