The well-known dwarfism belongs to dwarfism. The criteria for judging dwarfism in children can be referred to the following two aspects: 1. Generally speaking, if the height of a patient of the same race, sex and age is more than two standard deviations below the average height of the normal population or below the third percentile in a similar environment, it can be diagnosed as dwarfism.
2. The child’s height growth rate can also be used as a criterion. Infants and toddlers under 3 years old have a growth rate of less than 7 cm/year; 3 years old to prepubertal, a growth rate of less than 3-5 cm/year; and puberty, a growth rate of less than 5-6 cm/year, all belong to slow height growth.
Parents can write down the height of their child’s annual health checkup and plot it as a line. If the line flattens or tends to decline, it indicates a problem. A rough observation is that if a child grows less than seven centimeters per year before the age of three, less than four to five centimeters per year between the age of three and puberty, and less than 5.5-6.5 centimeters per year during puberty, he or she should go to a pediatric endocrinologist for early consultation.
