Parents want their children to grow taller, but not all families get what they want. There are many unfortunate misconceptions about a child’s height. Generally, parents always find out whether their children are tall or short after their development has set in. Even if they find that their children are shorter than their peers, they often think that they are “late growers” and think that they will naturally grow taller when they develop later, which is called “jumping up”. The best opportunity for treatment is often missed. So is a child’s short stature a “late growth”? It is difficult for parents to judge by imagination alone. The correct way to determine this is to go to a regular hospital for a detailed examination. Short stature refers to a child whose height is 2 standard deviations below the average height of normal children of the same race, age and gender under similar growth conditions, or whose height is below the 3rd percentile of the height of children in that population. Growth is a complex physiological phenomenon, which is the result of a variety of factors, among which, in addition to the role of human endocrine regulation, there are two basic factors, namely congenital genetic factors and acquired nutritional and environmental factors. Among them, genetic factors account for 60%-70%, genetics determines the possibility of growth and development, and environmental conditions determine the speed of growth and development and the degree that may be achieved. In the process of growth and development of children, the growth of height depends mainly on the growth of the epiphysis between the bones, which plays a decisive role in the development of height throughout the process. The epiphysis is the center of bone growth and development, and by continuously ossifying to increase the length of the bone, a person’s height also increases. Bone age is the age of skeletal development, which represents the bone maturity at each age and is a good indicator to assess the growth and development of a child. Therefore, if you want to know the growth potential of a child and whether there is still room for growth, you need to go to the hospital to take a hand x-ray for bone age determination. There are two growth spurts in a person’s life: infancy and adolescence. In the first year after birth, height can increase by 25 cm, and in the second year by about 10 cm; after the age of 2 years until puberty, basically maintain a uniform growth rate of about 5-7 cm per year, while entering the pubertal development period, the average annual height increase can be 8-10 cm, during which girls’ height increases by about 23-25 cm, and boys’ height increases by about 25-28 cm. These two periods are critical in determining a child’s height in adulthood. Medical research shows that 4-8 years old is the best time to treat dwarfism. During this period, parents are advised to keep detailed records of their children’s growth, help them measure their height and weight regularly and keep records to understand their annual growth rate, and think of any growth disorders if the growth rate is less than 4 cm per year for children over 3 years old. In addition, parents should also record the child’s youthful development, such as when the girl’s breasts develop, when the first menstruation, when the boy’s testicles develop, whether there is a change of voice and other phenomena. This is because these physiological phenomena are sometimes closely related to the child’s growth.
