How do female bones develop?

Bone development is the most important issue that parents are concerned about for their children, because in today's society, height is very important in interpersonal communication and other occasions. Therefore, many parents keep feeding their children milk and calcium tablets when they are young. But we can find that many of them are ineffective. So what is the process of female bone development? Let us take a look at it below!

⑴ Heredity: Members of a nation or family have similar heights. For example, white people are generally taller than yellow people. In a family, if the parents are tall, their children tend to be taller. This can be said to be a congenital factor, that is, it is related to genetics.

⑵Environment: that is, acquired factors, which also play an important role in bone growth.

① Nutritional factors, such as a reasonable ratio of calcium and phosphorus in food, help to grow taller.

②Diseases can affect bone development. For example, pituitary diseases can cause too much or too little synthesis of growth hormone, which can affect height. Sex hormones promote bone development. If a large amount of sex hormones are produced too early (precocious puberty), people will grow fast during adolescence, but after maturity they will be shorter than people of the same age.

③ Mood swings, reduced sleep, and irregular lifestyle can all affect overall development and the function of endocrine organs, leading to abnormal physical development.

④Physical exercise can enhance physical fitness and help grow taller. According to statistics, teenagers who regularly participate in physical exercise can be about 4 cm taller than those who do not.

Early puberty can make children shorter

There are more than 8 million people in my country who suffer from short stature due to growth retardation, and the number is increasing at a rate of 161,000 people each year. Among children aged 0-14, the prevalence rate is over 3%. Surveys show that more than 90% of dwarfism patients suffer from inferiority complex, which affects their interpersonal relationships, education, employment, marriage, etc. Puberty has a huge impact on a person's height.

With the improvement of living standards, the average height of teenagers in my country has gradually increased. But at the same time, some children have become shorter. Dwarfism, like obesity and precocious puberty, seriously endangers the health of adolescents. Many parents brought their children to anxiously ask questions such as "the cause of dwarfism", "the relationship between puberty and growth and bone health", and "nutrition and growth and development".

Puberty occurs one year earlier and the basic height is lost by about 5 cm

Dwarfism refers to a height that is more than two standards lower than the average height of people of the same race, gender, and age. The child's height growth rate can also be used as a criterion for judgment. If the growth rate of infants under 3 years old is less than 7 cm/year; the growth rate from 3 years old to before puberty is less than 3-5 cm/year; and the growth rate during puberty is less than 5-6 cm/year, it means that there may be height problems.

A person's final adult height (lifetime height) is the result of the combined effects of the interaction of various factors. Adolescence is the "spring" in the human life course, which has a huge impact on a person's stature growth and organ function maturation. A person's final height is composed of two parts: the basic height at the beginning of puberty (accounting for 80%) and the height gained during the "sprint" during puberty (about 20%).

There are two main reasons why puberty affects final height: one is the growth rate before and during puberty; the other is the length of the growth cycle determined by the early or late timing of puberty.

Normal puberty begins between the ages of 10 and 12. Both boys and girls grow about 5 cm taller each year before puberty. The entire puberty lasts about 3-4 years, and the height gained during this period generally does not vary too much among different individuals. Boys grow about 28 cm taller and girls grow about 25 cm taller.

Excess nutrition will cause the onset of puberty to be significantly advanced, and the growth time before puberty will be shortened. For every year of early puberty, there will be a loss of about 5 cm in basic height. Even more unfortunately, for those who develop too early, especially those with precocious puberty (girls who develop puberty before the age of 8 and boys who develop puberty before the age of 9 can be defined as precocious puberty), the duration of their puberty will be significantly shortened, and the height gained through the "sprint" will be greatly reduced. This can cause these children to be shorter throughout their lives.

Bones make up the largest part of the human body, so whether a person's bones develop well will directly affect the development of the whole person. So I would like to warn all parents here to pay more attention to their children’s bone development!
