What are the criteria for dwarfism in children?
In the diagnosis of short stature in children, the growth rate of height is more important than the absolute height. The so-called growth rate refers to the number of centimeters of height growth per year. There are two peak periods of human growth rate, namely 0 to 3 years old and puberty.
① The average height at birth is 50 cm, the first year of growth is about 25 cm, the second and third years of growth of about 10 and 8 cm each.
② Puberty (about 14 years old for males and 12 years old for females) begins with an annual growth of 8 to 12 cm, along with the appearance of male and female sexual characteristics.
(③Growth of 4 to 7 cm per year between the age of 3 and puberty.
If the growth is less than 4 cm per year between the age of 3 and puberty, or if the growth rate of height is less than 70% of normal before the age of 3 and during puberty, it is considered slow growth. If a child’s height is still within the normal range, but the growth rate in the last 1-2 years is lower than the normal rate, he or she should also seek medical attention to check the cause so that the disease can be detected early and get early treatment.
