Girls stop growing taller

There should be no exact age or time point, just like they are all girls, some grow faster and some grow slower, it's the same. Many people grow very fast when they are 13-14 years old. After this period of time, they think they will no longer grow taller. But if you measure them every year, you will find that they are still growing, but it seems very slow, so slow that it can be ignored.

Height refers to the vertical distance from the starting point (v) to the ground surface, usually measured in centimeters (cm), but meters (m) are also commonly used. Height refers to the length of the vertical part of the body, which is derived from the vertical growth and development of the body and is greatly influenced by genetic factors. Girls start to grow taller earlier than boys, with a rapid growth phase at 12-13 years old, and growth stops at 19-23 years old. Boys start to grow taller later, with a rapid growth phase at 15-16 years old, and growth stops at 20-24 years old. When the long bones of the limbs and the spine have completed ossification, their height stops growing. There are many factors that affect height, such as genetic inheritance, nutrition, sports competition, environment, lifestyle, ethnicity, endocrine system, early or late estrus (the average height of menarche at the age of 18 is 5 cm higher than that at the age of 11), close relative marriage, medical development, etc.

Height and weight indicators not only reflect the development status of children and adolescents, but also correspond to the growth and development of various tissues and organs of the human body. Height refers to the length and proportion of the vertical parts of the body. It is caused by the vertical growth of the body and is greatly influenced by genetic factors. For men at the age of 20 to 24 and for women at the age of 19 to 23, the long bones of the limbs and the spine have completed ossification and their height stops growing.

There are many factors that affect height, such as genetic inheritance, nutrition, sports competition, natural environment, lifestyle, race, endocrine system, early or late estrus (the average height of menarche at the age of 18 is 5 cm higher than that at the age of 11), close relative marriage, medical development, etc.

Telescopic gene inheritance

Development is influenced by genetic inheritance, nutrition, exercise and various living conditions. But among the many factors that affect height, genetic inheritance is the most important.

The growth of the body from a single-cell sperm and egg into a complex multi-cell individual, and the development from a young baby into a strong individual, are all controlled by genetic inheritance. The heritability of height is as high as 0.75~0.92, especially for daughters, where the heritability is as high as 0.85~0.92. That is to say, 75%~92% of males and 85%~92% of females are affected by genetic variation. The maximum for men is only 25%, and the maximum for women is only 15%, which depends on other acquired factors. It is proven that genetic inheritance plays an extremely important role in the height of children. Relatively speaking, weight is less affected by genetic inheritance, with 63% of males and 42% of females affected by genetic inheritance. 37% of men and 58% of women are due to acquired environmental factors. This shows that the acquired natural environment has a great influence on weight.
