Growth is a basic characteristic of children and a mirror of their health status. In the process of pediatric growth and development, the determination of annual growth rate is a sensitive indicator for the early identification of growth disorders. The growth rate <6cm/year indicates the presence of growth disorders, and the causes should be promptly identified. If the deviation is too large, the child may have dwarfism.
