In China, the prevalence of dwarfism is very high, reaching about 3%. What is more frightening is that more than half of the netizens do not know that they need to observe children’s height from 0 to 3 years old; nearly 1/3 of them do not have the habit of measuring children’s height scientifically; 30% of them mistakenly believe that they can continue to grow taller as long as they keep up with nutrition; 75% of them do not know that children with short stature should go to pediatrics and endocrinology for examination. In fact, children’s growth and development is not only a problem of dwarfism, but also malnutrition, precocious puberty and obesity are major problems that plague parents of small children. In fact, 4 years of age is the cut-off point for determining short stature in children. Examination and treatment of dwarfism should go to pediatrics and endocrinology, and there is hope that children with dwarfism can reach normal height as long as they are treated early before the epiphysis closes. Therefore, parents must grasp the basic growth and development pattern of their children. How can we properly grasp the laws of child growth and development? The earlier you pay attention to your child’s height, the better, especially for children with a poor genetic background (i.e., neither parent is of ideal height) or with a special desire for height, special attention should begin at the time of their birth because the child’s nutrition and development in the mother’s womb will directly affect their growth and development after birth. Many parents mistakenly believe that they do not need to worry about their children’s future height before their children develop, and that their height will not be worse than others as long as they develop normally, and only when their children should grow taller but still do not show signs of growth do they start to worry. At this time, most children’s epiphyses have already closed or will close, missing the best time for treatment. Medical experts remind parents that a child’s healthy growth depends on a variety of factors, but proper nutrition, scientific exercise and regular checkups are important factors to ensure healthy growth. Under the premise of ensuring children’s scientific diet and nutrition, scientific exercise can promote children’s development, improve physical quality and strengthen physical resistance. Scientific exercise can also adjust the body shape, making the body proportion more reasonable and height more ideal. According to Professor Lu, exercise will also stimulate the pituitary gland to secrete growth hormone, promote the production of epiphyseal bone cells, so that the growth of dry bone, so that the bone density increases. Regular scientific exercise can make muscle volume and muscle mass increase, thus improving muscle movement speed and endurance. At the same time, exercise burns excess calories ingested and keeps fat in the body within reasonable limits. Exercises that help children to increase their height are: high jump, rope skipping, basketball, volleyball, running, single and double bars, pull-ups, calisthenics, swimming, running, etc. In addition, parents should also give their children regular physical examinations, record the measurement data at different times, and connect the points traced several times to draw a simple growth curve. If the child’s growth curve shows a smooth upward trend, it indicates a normal growth rate; if the curve does not change much or decreases, it means that something may be wrong with the child’s growth. By numerical estimation, if the growth rate of children under 0-3 years old is less than 7cm/year, 3 years old to pre-pubertal growth rate is less than 4-5cm/year, and puberty growth rate is less than 4.5-5.5cm/year, it can be clearly diagnosed as growth retardation, and parents should bring their children to the pediatric department of the hospital for examination as soon as possible to identify the causes of the retardation and carry out targeted treatment.
