In recent years, more and more children are paying attention to the problem of their children’s height, and many parents are regularly measuring their children’s growth rate, and even seeking guidance and help from doctors in hospitals. The child’s height and genetics, nutrition, exercise, sleep and other factors have an impact. 1, genetic factors The child’s height is influenced by the parents’ genes, generally the parents of high children’s height is also high, parents short children also grow short. However, it is not absolute. For example, if parents are short due to acquired factors (disease, trauma, malnutrition, etc.), their children may not be short. Suggestion: If the parents are short, also trace the height of the child’s grandparents, grandparents and uncles, aunts, uncles, etc. to see if they are short. If these relatives are not short, the child must not be short. 2. Nutritional status Adequate nutrition is the guarantee for children to grow taller, while poor nutrition will definitely cause children to be short. But not the more nutrition supply and the better quality of nutrition, the higher the child must grow. Suggestions: comprehensive and balanced nutrition, rather than the pursuit of high-end high-quality nutrition. Otherwise, eating too well, too full will cause excess energy, and cause obesity and precocious puberty, but will affect the height. 3, exercise time and intensity If the child does not love activity, sitting indoors all day long playing computer, watching TV, is not conducive to the growth of long bones, is not conducive to the stretching of the spine, is not conducive to receive sunlight and lead to vitamin D deficiency, which is not conducive to height growth. Suggestions: motivate children to do more longitudinal exercises (such as jumping rope, touching high, playing blue ball, etc.) to promote cartilage ossification of the epiphysis of the long bones, subperiosteal bone formation, so that the growth of long bones, thickening, from the face to make a taller. 4, sleep condition Children who are depressed all day and night will affect the secretion of growth hormone and the normal functioning of the body systems, which will cause children to be short. Likewise, long-term sleep deprivation and late sleep will also affect the secretion of growth hormone, causing children to be short. Suggestion: It is best to go to bed before 8:30 pm, no later than 9:30 pm, and get up after 7:00 am. Sleep is really important! Parents must pay attention to ~ 5. Diseases Many chronic diseases can affect the height of children. For example: chronic or recurrent asthma causing systemic hypoxia, congenital heart disease reduced blood supply to the body circulation resulting in insufficient blood and oxygen supply to the whole body, chronic renal dysfunction, diabetes, etc. can cause growth disorders and cause short height. Suggestions: For children’s diseases, on the one hand, we should actively prevent, some diseases should be examined and diagnosed in a timely manner, and treated in a timely manner after discovery.
