14-year-old girl Xuan seems to have lost weight in the last six months. When Xuan was 9 years old, her underwear first saw blood (menarche), and her mother didn't care. Now she is 14 years old, but her height is only 148cm. Her mother is in a hurry. As soon as the summer vacation was over, my mother took her to Xinzhou District Maternal and Child Health Hospital. After a series of examinations and evaluations, Dr. Li told her mother that there was little room for growth and the best opportunity for effective medical intervention had been missed. This is unacceptable to Xuan and her mother. Xuan's mother said that she 17 would grow taller. Why didn't my family grow up when she was 14 years old? Are you mistaken, doctor? Do my children grow up late?

First, how to distinguish between "short" and "late long"

(a) when the child appears in the following circumstances, it may not grow tall!

Sitting in the first three rows of the classroom for a long time.

② clothes 1~2 years later can still be worn.

(3) The annual height growth of children over 3 years old is less than 5cm.

(4) Half a head shorter than peers.

(2) When the child has the following situations, it may be precocious puberty, which also has an impact on the child's lifelong height:

(1) Breast development of girls before 8 years old or menstrual cramps before 10 years old.

② The development of testis and penis occurred before the boy was 9 years old.

All the above scenes are "short", but in real life, many parents don't notice that their children are short. They think that children who grow up late will definitely wait until they are "short". What are the chances of growing up that night?

For example, a child who grows late is like a dark horse killed three months before the college entrance examination! Usually the grades are average, even worse than the average level. The achievements in the last three months have advanced by leaps and bounds, and it is easy to counterattack!

From a height point of view, such a "dark horse" does exist, especially in the era when material life is extremely scarce. Many parents have the impression that "who is still growing up in high school?" But now the nutritional level has been greatly improved, and the proportion of late growth is extremely low. Often, among the 65,438+000 children waiting for later growth, 97 have lost the chance to grow taller!

(3) What is a long night?

Late growth usually refers to "delayed physical puberty", that is, when normal children enter puberty, their growth does not accelerate, but after other children stop growing or slow down, their height suddenly increases.

Yes, it's a typical long night!

Careful observation shows that most children do not belong to this category. If you don't help your child with height improvement or treatment at the best time, you will lose the opportunity to help your child grow taller forever.

Second, how to identify whether it is late or long? -Bone age

Bone age is the "golden key" to evaluate children's biological age on the spot and their height and growth level objectively.

First of all, it is clear that the proportion of "late growth" is very low, and bone age usually lags behind age. It is recommended that children over 3 years old have their bone age measured once a year. Once a child has growth retardation, short stature, early bone age and unsatisfactory height, it is necessary to check whether there are growth and development diseases, such as hypogonadism, growth hormone deficiency, hypothyroidism and congenital ovarian hypoplasia (Turner syndrome), and then consider them comprehensively from the perspectives of nutrition, sleep, exercise and emotion.

However, some parents will ask, this is a bit abstract. Are there any specific authoritative indicators for reference?

Of course, there is a reference standard for the height of children and adolescents in China. When your child's height is lower than the 300th percentile of the height of children of the same age and sex, it belongs to short stature. See the table below for details:
