The initial judgment is made based on the growth situation: any growth rate below 7 cm per year in infancy (under 3 years old), below 4-5 cm per year in childhood (3 years old – puberty), below 5.5-6.5 cm per year in puberty, and below 2 standard deviations (-2SD) from the average height of healthy children of the same age (refer to the height standard table) or below the 3rd percentile of the growth curve is Short stature. If your child’s height is less than the value in the “short” column compared to the height of children of the same age and sex in the table above, you should take your child to an endocrinologist as soon as possible. If your child’s height is between short and short, leave a message with the child’s birth year and height and reply to the parents after evaluation. If the child’s height is between short and average, the child’s height needs to be monitored regularly every three months. A height ≥ the mean value indicates that the child is growing normally. (Note: If secondary sexual characteristics appear before the age of 8 weeks for girls and 9 weeks for boys, and the height is temporarily higher than the height of children of the same age, precocious puberty may occur and parents should seek medical consultation or advice promptly.)
