Human growth can be divided into four stages, namely fetal, infant, childhood and adolescence. Delayed growth at any of these stages can result in eventual short stature. Among them, infancy and adolescent development, are two growth peaks. A. Seize the rapid growth period Human growth can be divided into four stages, namely fetal, infant, child and puberty. Delayed growth in any one of these stages can cause eventual short stature. Among them, infancy and puberty are the two growth peaks. This stage of infancy is the fastest growth rate and the period most susceptible to disturbance by external factors. Do not let your child fall behind in the rapid growth period. Second, pay attention to nutrition without partiality Now children’s protein intake is a lot, but micronutrients often due to partiality and insufficient intake. Some parents believe that strengthening nutrition is to eat more chicken, duck and fish, can not eat or eat less food. In fact, the energy needed by the body is mainly obtained from carbohydrates, and protein can only be fully utilized by the body if there is sufficient energy. Excessive protein intake increases the burden on the liver and kidneys, which can easily cause indigestion and constipation, but inhibits the appetite of children. Some children are over-nourished resulting in obesity, which can easily trigger precocious puberty and eventually short stature. Smart mothers should pay attention to the reasonable mix of diet, do not let children eat too much snacks and affect the intake of important nutrients. The most effective way to “pull up” is to have an hour outdoors every day. Exercise can stimulate the secretion of growth hormone, promote metabolism, enhance appetite, can promote bone growth, make bones longer, thicker, bone density increases, but also make muscle fibers thicker, improve muscle strength, speed and endurance, but also in the rapid growth period to prevent obesity. Fourth, sufficient sleep to ensure that the hormone that promotes human body growth – growth hormone, the secretion in the sleep state is about three times the amount secreted in the waking state. Sleep muscle relaxation, conducive to joint and bone stretching. Fifth, actively prevent and control diseases Repeated respiratory infections and diarrhea can significantly hinder the growth and development of children. Long-term diseases such as chronic infections, chronic hepatitis, chronic nephritis, asthma, heart disease, anemia, etc. can affect height growth. In addition, major diseases such as chromosomal abnormalities, endocrine disorders, and bone and cartilage development disorders can also result in significantly lower height than children of the same age. There is an increasing number of children with precocious puberty, which seriously affects the physical development of children. Precocious children may be taller than their peers at the beginning, but once they enter puberty, other children develop normally, while precocious children grow slowly due to the lack of reproductive capacity of bone cell division; a large amount of sex hormones also prompt the epiphyseal cartilage to close prematurely, making growth stop automatically. The premature growth of a child’s height is often a sign of premature sexual maturity, which needs to be taken seriously by parents. Bone age is the most reliable indicator of the maturity of the human body. Abnormally early or backward bone age can reflect the adverse factors affecting growth and development. Based on bone age, actual age and height, adult height can be predicted. Predicting height can avoid missing the best time for treatment or unnecessary treatment. If your baby has height problems, you should go to the hospital to measure the bone age in time. Seven, establish a growth and development file Combining the bone age and predicted height values at different times, you can determine whether the development is normal. For different situations of height of children and adolescents, a targeted guidance and treatment plan will be formulated. If the height is not ideal, but the bone age has basically matured, even if there is not much room for growth, it is still possible to realize the last growth potential through reasonable guidance.
