With the development of society, the incidence of precocious puberty in children has been increasing in recent years, which not only makes the majority of parents quite worried, but also has been a matter of great concern to society. So, how to recognize precocious puberty in children? What are the factors that contribute to precocious puberty in children? What is precocious sexual maturity Precocious sexual maturity is a kind of sexual development abnormality characterized by the early appearance of sexual maturity. It is generally believed that girls have their second sexual characteristics, such as breast development and vaginal discharge, before the age of 8, or the first menstruation occurs before the age of 10. In boys, sexual development begins before the age of 9, such as the growth of beard and protruding throat nodes, etc. These can be diagnosed as precocious puberty. Precocious puberty can cause some harm to children, because of the influence of sex hormones in the body, premature acceleration of physical growth, shortening of the growth period and early cessation of growth, resulting in a final height lower than that of normal children of the same age who develop according to normal puberty. In addition, although the sexual characteristics of precocious children develop earlier, but the level of psychological and intellectual development is still the actual age level, premature appearance of sexual characteristics and development of reproductive organs will lead to immature children’s psychological tension, mental depression, and also bring a lot of inconvenience to life, and serious cases even affect reading and learning. What factors lead to early sexual maturity in children? With the accelerated industrialization of society, environmental pollution is becoming increasingly serious, which is also a major factor contributing to the precocious puberty of children. In addition, the child’s daily diet, parental cosmetics, and media stimulation are also factors that cannot be ignored. Environmental pollution Hormone-like pollutants in the environment, such as detergents, pesticides, and plastic products, can produce substances that can be decomposed in the atmosphere to produce estrogen-like active substances, which may be ingested by children or accessed through the skin, leading to precocious puberty. Children’s daily diet On the one hand: in the meat. Most of the poultry sold in the market today are fed with feed mixed with fast growth agents, and the residues of “maturity promoters” in poultry meat are mainly concentrated in the glands of the head and neck part of poultry, so eating the necks of chickens, ducks and geese becomes a high risk of “precocious puberty”. The behavior. On the other hand: on vegetables and fruits. Parents often give their children anti-seasonal vegetables and fruits, such as strawberries, grapes, watermelon, tomatoes in winter, and pears, apples, oranges and peaches in late spring, which are mostly anti-seasonal or ripen early with the help of “ripening promoters”, which can also lead to early sexual maturity. The influence of parental cosmetics Children’s skin is thinner than adults, the skin’s defense barrier function is weak, sensitive to external stimuli. Most adult cosmetics contain chemical ingredients such as fragrances, preservatives and various organic compounds, and often add glucocorticoids or estrogen, the long-term use of such cosmetics by children can lead to precocious development of children. With the development of media, such as newspapers, television, the Internet, especially the popularity of the Internet, reports and images about sex can be “everywhere”, children may involuntarily hear and see, which will stimulate the hypothalamus pituitary nerve reflexes, so that the hypothalamus pituitary gonadal axis of early start This will stimulate the reflexes of the pituitary nerve in the hypothalamus, causing the pituitary gonadal axis of the hypothalamus to start early, which will lead to precocious sexual maturity in children. The child’s precocious sexual maturity, whether for parents, schools or society, is a problem that can not be ignored, we must take advantage of the strength of all aspects, the correct understanding of precocious sexual maturity, and give the child with precocious sexual maturity to positive education and guidance.
