Height standards for babies aged four to four and a half and the reasons for their short stature

Four and a half years old is the time when children are adorable, but many parents actually have hidden worries in their hearts. Even though they feed their children a lot, they don’t know how well their children have absorbed the food, nor do they know whether their children’s height meets the normal height standard for a four and a half year old child, nor do they know what the reason for their children’s short stature is. So today I will answer your questions and let’s take a look at the following content.

Height Standard:

Age in months Height (in cm)

Male Female

48 months 92.5-116.5 91.7-115.3

May 1 month 94.0-118.5 93.2-117.4

54 months 95.6-120.6 94.8-119.5

reason:

1. Family inheritance

The baby's growth rate is normal, his bone age is normal, and his short stature is not serious. It's just that his parents are short, which is a family hereditary short stature.

2. Low birth weight babies grow slowly

A low-birth-weight baby is one that weighs less than 2500 grams at birth, has no family history of dwarfism, has no endocrine abnormalities, has a growth rate within the lower normal range, and has a normal or delayed bone age. Their growth hormone stimulation tests were normal, but there were changes in the rhythm of growth hormone secretion.

3. Disease or nutritional deficiency

Such as severe malnutrition, chronic heart, liver and kidney diseases, chronic diarrhea in infancy, etc. The short stature of these babies is not serious, and the growth hormone level in endocrine examinations is not low. After adjusting nutrition and treating diseases, their height and bone age will have a chance to return to the normal range.

Endocrine system also has a great influence on height. Lack of growth hormone, hypothyroidism, adrenal cortex hyperplasia and other reasons can cause children to not grow tall. In addition, systemic diseases such as malnutrition, cardiovascular system diseases, urinary system diseases, respiratory system diseases, etc. can lead to metabolic disorders and may also cause short stature.

4. Mental Factors

An unsatisfactory family environment, or lack of maternal love and companionship, can easily cause a baby to be too short, which is called "emotionally blocked dwarfism" abroad.

5. Pituitary dwarfism

This is caused by a deficiency of growth hormone. The male-to-female ratio of pituitary dwarfism is about 3:1. Obvious growth retardation will be found between the ages of 2 and 4, with a growth rate of less than 4 cm per year. However, the limbs of such babies are relatively symmetrical, but their faces are childish and fat accumulates in the abdomen, which are typical manifestations of this disease. In addition, delayed bone age is often consistent with height age, tooth eruption and replacement are delayed, and intelligence is normal.

Warm reminder: If your baby shows signs of dwarfism, diagnosis and treatment should be initiated as soon as possible to minimize adverse effects.

The above is the normal height standard for babies aged four to four and a half years old and the five major reasons why children are short. Parents can check to see if their children are within the normal range, or see which of the five reasons is the cause if their children are short. This way, they can prescribe the right medicine and let their babies grow up healthily.
