There are certain regularities in the height growth of children.
Normally, there are two peak periods of height growth, the first peak is infancy and the second peak is puberty. For parents, grasping the pattern of height growth of their children can help detect abnormalities in their height at an early stage, so that they can take appropriate treatment or intervention measures earlier.
1. At birth, newborns.
Average height of about 50 cm.
2.In the first year of life.
The fastest growth rate, with an increase of about 25 cm and a height of about 75 cm at the age of one year.
3, the second year of life.
Growth of about 10 centimeters, about 85 centimeters at 2 years of age.
4, after 2 years of age.
Growth rate gradually decreases, with an average annual growth of about 5 to 6 cm.
5. Entering puberty.
Boys can grow about 28 centimeters, girls about 25 centimeters.
6.After puberty.
Height growth gradually slowed to a halt.
Children’s height growth has a certain pattern, but also affected by a variety of factors, there are considerable individual differences. The so-called normal value is not absolute, and different factors should be taken into account in order to determine whether it is normal or abnormal. At the same time, systematic and continuous observation is needed to understand the real situation of the child’s growth and development.
Factors that affect the growth of children’s height include
1, genetic factors.
The growth and development of children are influenced by the genetic factors of both parents, the parents of high children, genetic height is higher, the adult lifetime height is relatively higher. But genetic factors affect the height of only about 30%.
2, gender factors.
Boys and girls due to different physiological structure, developmental characteristics, their respective growth and development are different, we need to evaluate the growth and development of children, according to the sex of men and women to evaluate separately.
3, nutritional factors.
Balanced nutrition is the material basis for the growth and development of children. Insufficient nutrition will lead to weight gain or even loss, which will eventually affect the growth of height, and even affect the function of other systems, such as immune function, endocrine function, neuromodulation function. And the younger the age, the greater the impact of nutrition. However, excess nutrition, resulting in obesity, precocious puberty, etc., will also affect the child’s adult lifetime height.
4, disease factors.
Acute infections often do not increase or reduce weight, while chronic infections affect both weight and height growth. Endocrine diseases such as.
(1) Growth hormone deficiency dwarfism: If no supplemental replacement therapy is given, the child will have slow height growth and, at the same time, slow sexual development.
(2) Hypothyroidism: It has a more prominent effect on growth, often affecting height growth and neurological development, and is medically known as “cretinism”. Congenital diseases such as congenital dysmorphia can have a significant impact on the physical and intellectual development of the child.
5. Maternal pregnancy.
The development of the fetus in the womb is influenced by the mother’s living environment, nutrition, emotions and diseases.
6.Life environment factors.
A good living environment, a harmonious family atmosphere, healthy living habits, and proper physical exercise are all important factors to ensure that the growth and development of children reach the best state.
