How much potential a child has for growth genetics largely determines the child’s growth potential, but the child’s growth is influenced by a combination of many factors. If both parents of the child are of normal height and have good conditions for growth and development, then the child’s growth and development will be more satisfactory; on the contrary, if the child’s parents are short and the parents do not pay attention to the child’s acquired nutritional intake and exercise, then the child’s height will not be ideal. There is a formula to roughly calculate the child’s adult height (genetic target height) range: boys for the average height of parents plus 6.5 cm, girls for the average height of parents minus 6.5 cm, the resulting value in ± 5 cm that is the child’s adult height range. Hereditary target height has a wide range of fluctuations, and a variety of factors such as nutrition, sleep, exercise and disease in later life can have a great impact on the final height. How to make the most of your child’s growth potential Although genetics largely determines a child’s growth potential, final height is influenced by many factors. Adequate nutrition is the basic guarantee of growth and development. Protein is the material source of bone and muscle growth, and at the same time promotes the secretion of growth hormone, which is the most essential element of children’s growth and development. Therefore, protein-rich foods, such as eggs, meat, fish, soy products and dairy products, should be given as part of the children’s dietary regimen. Exercise of proper intensity can directly promote the secretion of growth hormone, while adequate physical exercise can enhance children’s appetite and bring them healthy sleep, which is helpful for growing taller. Exercises that are beneficial to growth include jogging, jumping rope, dancing, playing basketball, volleyball, swimming and other longitudinal pressure exercises, because the development of bones comes to some extent from longitudinal pressure, and too strong pressure such as weight lifting will prevent the bones from growing longitudinally, and children should avoid doing such exercises. Since the secretion of growth hormone generally peaks at night about one hour after the child is asleep, sufficient sleep can promote the secretion of growth hormone, so parents should urge their children to fall asleep at 8 or 9 o’clock every night to ensure sufficient sleep. In addition, physical development is influenced by the natural environment, social environment and family environment, especially for children of low ages, the family environment is particularly influential. Parental care helps children grow taller, but if children grow up in a disharmonious family, the lack of parental care often affects their physical growth, so it is important to create a healthy and caring environment for children. The growth rate of height is not uniform. People experience two periods of rapid height growth throughout their lives, namely infancy (0-3 years old) and adolescence. During puberty, the child’s height will “surge” due to the synergistic effect of sex hormones, but also due to the effect of sex hormones the child’s epiphysis will close rapidly and the height will not continue to grow. Boys’ puberty generally begins at the age of 12 to 13, with an annual growth rate of 7-10 cm and an average height growth of 25-28 cm; girls’ puberty generally begins at the age of 10-11, with an annual growth rate of 6-9 cm and an average height growth of 23-25 cm. Infancy and adolescence are important periods for height growth and should be given great attention.
