To know which stages are the shutdown periods for children to grow taller, we must first talk about a person’s growth and development. Because height is one of the main measures of a person’s growth and development, it is the outward expression and reflection of a person’s growth and development. A person starts the growth and development process from the fertilized egg. Human growth and development is alternately fast and slow, and the process of fast-slow-fast-slow. Throughout the growth period, the first growth spurt occurs in fetal life and the second in early adolescence. During the first growth spurt, the height grows about 27.5 cm in the middle 3 months of pregnancy, accounting for 1/2 of the height growth during the fetal period, which is the fastest growing stage of height in a lifetime. After birth, especially in the first 3 months after birth, the growth is the fastest, with an average monthly growth of 3.0~3.5 cm, 3~6 months with an average monthly growth of 2.0 cm, and 6~12 months with an average monthly growth of 1.0~1.5 cm. Therefore, the total growth in the first year is about 25 cm, which is 50% of that at birth (50 cm on average) and is the fastest growing year in a person’s life. In the second year, the height increases by 10 cm, which is also rapid. Later on, it slows down year by year and remains relatively stable, with an annual growth of less than 5 cm near puberty. Thus, from birth to 1 year is the first peak of height growth. Until the beginning of puberty, about 11 years old for girls and 13 years old for boys, there is a second growth spurt, the puberty spurt. At this time, the annual increase in height value is generally 6 to 8 cm, individual up to 10 to 12 cm, which is a surge, sprint, as if the sprint at the end of the race. After about 3 years, the growth rate will slow down again, and the height will be basically set at the end of the sexual maturity period, that is, when boys are 18-20 years old and girls are 17-19 years old. However, the width and thickness of the human body can still grow in the lateral and anterior-posterior directions. The growth of height usually lasts for 2 to 3 years. Boys can grow 7~9 cm per year and up to 10~12 cm for a total growth of 25~28 cm. The growth spurt is over when the voice changes, and the growth rate slows down significantly. Usually when the beard grows to the point where it needs to be shaved, it indicates late pubertal development and is close to final height. Growth begins to accelerate when a girl’s breasts begin to develop. Usually the fastest growing age for girls is between 11 and 13 years old, when they can grow 7 to 9 cm a year for about 3 years, for a total growth of 20 to 25 cm. The growth rate of girls slows down 6 months before the first menstruation, and slows down significantly after the first menstruation. The height growth potential of girls after menarche is very small. The formula for predicting adult height based on the height at menarche is: height at menarche (cm)/(0.9585±0.0178), so the height grows about 4~8 cm from menarche to complete epiphyseal closure. In summary, children at the age of 0~1 years and puberty development is a critical period for children to grow taller.
