Nowadays parents are very concerned about their children’s height, parents who grow too fast are anxious, parents who grow too slow are even more anxious, but these parents want to help their children but often have no way to do so. In fact, when it comes to height, we have to mention the “bone age”, the bone age can, to a certain extent, reflect the child’s future height development, to help children grow and develop has a very important monitoring role, want to help children grow taller to do a good job of monitoring the bone age. First, the correct evaluation of the relationship between bone age and age A person’s biological age is the bone age, the physiological age is the actual age, the child’s bone age does not necessarily match the age. Specifically divided into the following cases. 1.Bone age is greater than 2 years old: It indicates that the future adult height level of children may be lower than the current height level, and should immediately exclude the possibility of early development; 2.Bone age is less than 2 years old: Growth hormone deficiency or thyroid hormone deficiency and other diseases should be excluded 3.Bone age is greater than 1.3 years old: It is possible that early development, height growth potential is small, and needs to be evaluated according to other examination results 4.Bone age is less than age 1.3 years old: height growth potential, need to evaluate according to the height of the bone age, but more factors affecting height, need to continue to monitor the height evaluation 5, bone age equal to age: bone age and age synchronous growth, according to the height of the bone age evaluation 6, bone age and age difference of 1.3 years or less: normal growth, need to evaluate according to the height of the bone age and continue to monitor the height Note: Usually The child’s bone age and age are generally in line with each other, and the fluctuation is not more than 1 year, and the fact that the bone age is less than the age does not mean that the child must have more room for growth. B. When do I need to monitor my baby’s bone age? The height of a baby within 2 years old is basically a medium development, and it does not have much significance to the future height prediction, so basically there is no need to measure the bone age within 2 years old, and if there is a medical need to measure the bone age after 2 years old, the impact on the child is within the safe range, so parents do not need to worry. It is recommended to measure the bone age once every six months, and those with normal height can be measured once a year for continuous monitoring. Generally speaking, the epiphysis tends to close when the child is 14 or 15 years old, and there is very little room for the child to grow taller after development, so it is important to make height prediction and targeted height management in advance before puberty starts (before the age of 9 for girls and 10 for boys), and the child can grow 2-4cm more with each year of early management before puberty. Height Management requires bone age Joint evaluation of multiple factors affecting height Bone age is an important indicator for evaluating a child’s growth and development, but it is not the only indicator. Parents taking bone age films for their children only understand the relationship between their children’s bone age and their age, and cannot accurately predict their children’s lifelong height. The growth of a child’s height is influenced by a combination of factors, including congenital genetic factors and acquired nutrition, exercise, sleep, psychology, disease, etc. In order to help children manage their height, it is not reliable to rely only on a simple bone age film. It is necessary to consider and analyze a variety of factors that affect a child’s height in order to accurately predict the future lifetime height, understand the gap between the future height and the desired height, formulate a reasonable height management plan, and finally help children grow to the desired height.
