Human growth and development can be expressed in two kinds of "age", one is physiological age, that is, the age calculated from our birth, a few years, a few months and a few days, everyone changes at the same rate; The second is bone age, referred to as bone age, because affected by various factors such as environment, diet, hormone levels, the speed of bone age change and age may not be completely consistent. There is a certain difference between bone age and actual age, which can reflect the potential and space of children's growth and development. By regularly monitoring bone age, doctors can detect abnormalities in children's growth and development in time and take appropriate intervention measures.
Frequently asked Questions about bone age testing
Q: Can bone age be measured at any time?
A: Bone age detection is generally carried out in children 4-15 years old, through timely detection, you can find children's growth and development problems, so as to adopt effective treatment methods in time.
Q: Is the X-ray bone age test highly radioactive?
A: According to the World Health Organization, the public should receive no more than 1 millisievert (mSv) of radiation per year. In exceptional circumstances, this limit can be increased to 5 millisieverts (mSv) . Bone age is usually taken of the left wrist (is far from the main organs of the end), take a bone age film radiation amount is very small, about 0.00012mSV, equivalent to 20 minutes of daily life sunbathing.
Q: Is there more room for growth with younger bone age?
A: The relationship between bone age and growth space is not simply linear. Although smaller bone age means that bone development is not mature, the size of growth space is also affected by many factors such as genetics, nutrition, and exercise. Therefore, the growth space of children cannot be judged by bone age alone.
Q: My father and I are of the same height. Is it possible for my child to be taller than us?
A: A child's height is influenced by genetic factors, but not entirely by the height of the parents. With proper nutrition and exercise programs, as well as timely growth and development interventions, it is possible for children to surpass the height of their parents.
Q: Children always sit in the first two rows at school, is it too short?
A: Children always sit in the first two rows at school and can not directly determine whether their height is short. A child's height development is influenced by many factors, including genetics, nutrition, exercise and so on. If parents are concerned about their child's height, bone age testing is recommended to understand the child's growth and development.
Q: When does a child need a bone age test?
A: Here are four scenarios
1. Abnormal growth rate: If the child's height growth rate is significantly slowed down or accelerated within two years, and the gap is larger than that of peers, this may be a manifestation of abnormal growth and development, and bone age detection is required in time.
2. Underweight or obesity: malnutrition or overweight may affect the progression of bone age, and the bone age of extremely thin or obese children may not be consistent with their actual age. Bone age testing is recommended to understand bone development.
3. Signs of late puberty: precocious puberty or delayed sexual development may affect the child's height and bone development, if the child has signs of late puberty, such as breast development before the age of 8 in girls or testicular enlargement before the age of 9 in boys, and on the other hand, there is still no secondary sexual development at the age of 13 in girls, bone age testing should be carried out to understand whether bone development is normal.
4. Frequent illness: Chronic diseases or the long-term use of certain drugs may interfere with growth hormone secretion and affect the normal development of bone age. If children are frequently ill or use certain drugs for a long time, they should also pay attention to their bone development and timely bone age detection.
Parents pay attention to the growth and development of their children, and timely take their children for bone age testing in order to timely detect and intervene in abnormal growth and development. At the same time, parents should also establish the correct concept of growth and development, to avoid blindly pursuing height growth and ignoring the health of children. Let us work together to protect the healthy growth of children!
