The height is difficult to break the "gene ceiling" "long height" product sales anxiety

　　"How to increase yourself quickly through fitness?" "Short, choose a major to be selected by the school, when you are in a relationship, you must be selected by the object, when you go to a shopping mall, you must be selected by the clothes, and when you find a job, you must be selected by the company. Who knows about the troubles? "The neighbor’s baby grows taller every day, and my baby wants to stretch too much." "My grandmother heard that bone soup supplements calcium, so she feeds me every day. After a summer vacation, I became fat, but I didn’t grow too much. "Height"... Searching for the keyword "height", there are many people on the Internet who want to break through the "gene ceiling" or share the bitter history of the "growth" road.

　　The "Report on Nutrition and Chronic Disease Status of Chinese Residents (2020)" shows that the average height of men and women aged 18-44 in my country is 169.7 cm and 158 cm, respectively, an increase of 1.2 cm and 0.8 cm respectively compared with 2015.

The heights of boys and girls aged 6-17 have increased by 1.6 cm and 1 cm respectively in each age group.

　　The average height continues to grow, and in order not to be left behind by others, everyone is "riveting enough."

　　The girl Tingting's father is 1.7 meters tall, and her mother is less than 1.6 meters tall. According to the genetic target height formula, Tingting's final height will theoretically not reach 1.6 meters.

Tingting’s parents could not accept this result. They were afraid that she would be joked and discriminated against because of her low growth. They sought medical advice everywhere, tried remedies for growing taller. They also bought Tingting a so-called "No fear of heredity, supplement growth." Factors that stimulate bone growth" health products.

　　Children from two to adolescence generally grow 5 to 7 cm per year.

After taking supplements, Tingting grew 8 cm taller a year, and her parents were very pleased.

But one day, Tingting’s mother discovered that her 7-year-old daughter’s breasts had begun to develop (the second sexual characteristic that began to appear before the age of 8 in girls and 9 in boys was precocious puberty-reporter's note).

　　After going to the hospital for an examination, the doctor believed that Tingting's gonadal axis developed ahead of schedule and her bone age was over 9 years old.

Since it is far from reaching the height that matches the bone age, the situation is not even as good as before taking health care products.

If you don’t seek medical intervention in time, you may not even grow up to 1.5 meters in the future.

　　There are many anxious parents like Tingting's parents who worry about their children's height.

The reporter found on an e-commerce platform that many "Changgao" products: Changgao artifacts, Changgao calcium tablets, Changgao hormones, Changgao stretchers, Changgao topical products, etc., only one of them is a Changgao calcium tablet. There are more than 50,000 orders per month.

　　Are long high calcium tablets really useful?

Will the abuse of hormones pose a threat to health?

Will it hurt if I use a stretcher?

No one cares.

What everyone cares about is "Goodbye too short", "Challenge big long legs", "10-15 cm taller" and other gimmicks marked by businesses.

　　Zhang Zhixin, director of the International Department of the China-Japan Friendship Hospital and chief physician of the Growth and Development Clinic, said in an interview with a reporter from China Youth Daily and China Youth Daily that drug and other interventions for familial short children within the population's normal height range are not recommended.

"In order to promote growth, parents give their children various health products, supplements, and heightening drugs, which are likely to promote early gonad development, early closure of bone age, early menstruation in girls, and early spermatorrhea in boys. Originally, girls could reach a genetic height of close to 1.6 meters. Indiscriminate use of drugs may eventually fail to reach a height of 1.5 meters. In addition, some drugs may also affect physiological safety."

　　Since supplements and health care products are risky, it is always right to drink more milk, bone soup, and eat more nutritious foods for children?

Not really.

Eating too much, too good, may stop growth prematurely.

　　"My child grew up faster in elementary school and was taller than other classmates. How come he doesn't grow up in junior high school? Can my child grow taller?" This is a question Zhang Zhixin is often asked.

　　Zhang Zhixin said that under normal circumstances, the bone age of boys is completely closed at the age of 18, and girls are completely closed at the age of 16.

The time from the beginning to the closing of the bone age is the growth period, just like the construction period of a building.

If the bone age is closed in advance, it means that the construction period of the building has been compressed. If you work overtime to build the building, the height of the child will be fine in the future.

Otherwise, the child may not reach the ideal height and become a "tall child and short adult".

There are also children whose bone age closes later and grows slowly.

It may be shorter than others in childhood, but "growth much taller" in adolescence.

　　The emergence of the phenomenon of "tall children and short adults" and the premature closure of children's bone age are likely to be the result of parents' excessive height requirements.

Excessive intake of protein may activate the gonads earlier, and sex hormones accelerate the growth of bone age, and the child develops earlier, and the time for growing taller is therefore shortened.

　　Zhang Zhixin found that during the epidemic, the number of children and adolescents in the respiratory department and pediatrics was decreasing, while the number of outpatient clinics of endocrinology, genetics and metabolism specialists in the country was increasing, or at least maintaining the status before the epidemic. Many children are looking for precocious puberty. And the bone age is often higher than the normal range.

"Children spend more time at home and can eat all the time. They eat more meat, eggs, milk, nuts, snacks, etc. than at school. Some parents cook a lot of food for their children every day in order to supplement their children’s nutrition, even There are also ginseng, sea cucumber, royal jelly, etc. Just like flowers, the flowers bloom early and no longer grow tall. Let the children grow fully naturally, and don’t have too much, off-season food intake, otherwise The chances of obesity, precocious puberty, and early development increase."

　　Zhang Zhixin suggested that we should scientifically understand and treat height issues.

"Height is not as high as possible. Height is the most suitable height established by humans through long-term evolution and environmental adaptation to meet and adapt to the size and functional activities of various organs and tissues of their own bodies. Not only humans, but also species are also regular. Some melons If the size in the south is smaller than that in the northwest, this is due to the survival of the fittest in the process of environmental adaptation and genetics."
