What is the standard height for bone age at 13 years old?

In daily life, many people do not know the relationship between bone age and children's growth and development. In fact, bone age generally reflects the maturity of the child. Bone age is actually the age of the child's development, not the age of birth. Bone age is determined by X-ray photography. Generally, bone age and height are not necessarily proportional. Children's height is mostly determined by genetic factors. Therefore, the standard bone age height of a 13-year-old child varies.

What is the relationship between bone age and children?

Every child has his or her own bone age, which reflects the child’s basic growth and development.

My child is 13 years old this year and is taller than his peers. Will he be taller than his peers in the future? In fact, it is not necessarily the case. It depends on bone age to predict.

It can not only determine the biological age of children, but also use bone age to understand the growth and development potential and sexual maturity trend of children early: bone age can also be used to predict the adult height of children. The determination of bone age is also very helpful in the diagnosis of some pediatric endocrine diseases.

What can we learn from measuring bone age?

There is a lot of information that can be obtained from measuring bone age:

① Predict the child’s exact height when he or she grows up

② Find out the child’s current true height level and develop a growth plan based on the child’s true level.

The best age to measure bone age is 3-15 years old. Measuring bone age at different ages has different meanings. It is recommended to conduct two bone age tests at the ages of 4 and 8.

Bone age testing should be done before the age of 3-10 years old. Growth and development diseases can be discovered based on the results and early treatment can be provided. At the same time, reasonable dietary structure adjustments and changes in lifestyle habits can be used to predict height and intervene in the final height.

For girls, bone ages at different ages correspond to different periods of height development. Children between the ages of 11 and 13 are often in a period of rapid growth in height. They have their first menstruation around the 9th month after the age of 11 and enter puberty. After the age of 17.3, they stop growing.

For boys, the age of each stage is slightly later than that of girls. Boys' height growth period is between 13 and 15 years old at bone age, puberty occurs after 13 years old at bone age, and they stop growing after 18.4 years old at bone age.
