The standard height of an 8-year-old girl is 131cm and the standard weight is 24kg. 20% of the weight above the standard is overweight, which may be obesity; 20% below the standard weight is underweight, which may be malnutrition; 20% of the height below the standard height is short stature, and if the height is too short, it is growth retardation. In this case, we need to further clarify the reasons for the child’s growth deviation, including endocrine diseases and nutritional genetic factors. If a little girl has growth retardation, including low weight and short stature, she must go to the pediatric endocrinology department or developmental department for an interview, bone age measurement, growth hormone and thyroid hormone levels, and if necessary, a head MRI to rule out endocrine disorders for symptomatic treatment.
