Precocious puberty – the death of the Chinese family
According to statistics, the incidence of precocious puberty in children aged 6 to 18 years old in mainland China is about 0.43%, of which the incidence rate is 0.48% for girls and 0.38% for boys.
This means that at least 530,000 children on the mainland have precocious puberty, and such a large group has long been not only a medical problem, but also a social problem.
The concept of precocious puberty to introduce to you, the general child puberty, boys and girls about the time is about 10-14 years old, individual children have to 7 years old or 8 years old on the situation of precocious puberty, such as some girls 7-8 years old can appear when the development of the child's breast nucleus, that is, the development of the breast, the breast appears induration or hard lumps, this time is regarded as precocious puberty.
Some children can also have menarche at the age of 8, which is also a manifestation of precocious puberty, which is precocious puberty in girls.
In addition, boys' precocious puberty can also be advanced, and boys' precocious puberty is some early to about 8 years old, and the thickness of hair, the appearance of beards, the obvious development of laryngeal knots, and the appearance of heavy voices can occur prematurely.
The secondary sexual characteristics of precocious puberty in children are mainly manifested in the appearance of Y hair in children, and the normal sexual development of this child is 10 to 13-14 years old, if the development of secondary sexual characteristics has appeared before, it is regarded as precocious puberty.
What harm does precocious puberty cause to children?
It mainly includes the following aspects:
1. Affecting the final height of the child, precocious children often follow the rapid development of bones, under the inducement of sex hormones, but also gradually lead to the premature closure of the epiphyseal.
In general, after girls have menarche and boys have their first missing J, there is only an average growth space of 5-7 cm, so precocious children will eventually be shorter than children of the same age;
2, can cause children's psychological disorders, precocious children although sexual characteristics appear in advance, but the intelligence, psychology is still the level of actual age, premature sexual characteristics and genital development make children have psychological disorders, extremely easy to cause children's inferiority psychology.
Especially girls, premature menstruation, often make them feel shy, nervous, this kind of psychology makes them distracted, and then affect learning, it is likely to leave a psychological shadow after their maturity;
3, precocious puberty can also cause children endocrine disorders, milder symptoms of children, mainly manifested as the imbalance of sex hormone levels, and more serious symptoms of children will be combined with other endocrine dysfunction, but also there will be a lot of clinical manifestations, so regular attention to the child's precocious puberty.
The most important thing about children's precocious puberty is to affect the final height, once the X hormone comes out, it will affect the closure of the epiphysis, and now there are many children with precocious puberty, parents can take their children to a professional hospital for treatment, so early detection can be early intervention, which can help children reach the actual final height.
It is not soy milk and chicken that "ripen" children
It is said that more and more children in the mainland have precocious puberty, and the culprits are fried chicken, soy milk eating too much and drinking too much.
Chicken?
Children eat chicken generally does not lead to premature puberty, chicken contains vitamins, protein, unsaturated fatty acids, as well as calcium, phosphorus, iron, potassium and other trace elements, can provide a wealth of nutrients, help to enhance children's immunity.
And the chicken itself does not contain sex hormones, children eating chicken in moderation is beneficial, will not cause precocious puberty, but pay attention to the practice and amount of food, eat too much fried chicken, will make the child obese, unhealthy.
Soy milk?
Giving your child soy milk is not related to precocious puberty, so drinking soy milk does not lead to precocious puberty.
Soybeans contain phytoestrogens, which can be absorbed by the human body through soy milk, but phytoestrogen and animal estrogen are two completely different concepts, and soy milk is a phytoestrogen, and the impact on the human body is not obvious, so it does not lead to precocious puberty.
What can parents do to prevent precocious puberty in children?
1. Reasonable diet, balanced nutrition, refuse tonics, and avoid the use of animal gonads and embryos.
2, do not turn on the night light to sleep. The environment with the night lights on will reduce the amount of melatonin secreted in the child's body, resulting in a weakening of the inhibitory effect on gonadotropins, resulting in precocious puberty.
3. Avoid excess nutrition caused by increased body fat and obesity. Increased secretion of leptin by fat cells, promotes pituitary gonadotropins, and promotes the process of sexual development.
4. Do not let children contact adult film and television works, books, etc., and do not encourage children to imitate some of adult behaviors, such as makeup.
5, away from the environment of endocrine disruptors, endocrine disruptors in the environment for a long time accumulation, chemical properties are stable, not easy to be biodegradable, and not easy to be discharged, so it can be accumulated in the body for a long time.
And its long half-life, easy to bioconcentration in the ecosystem through the food chain, to achieve a fairly high concentration.
