What is the formula for calculating the height of a child?

Parents all hope that their children will always grow up healthy and become tall and beautiful. Due to these expectations of parents, they will pay more attention to the height and weight of their children. At different stages of a child's growth, there is a certain standard range. Generally, this standard will be used to measure whether the child's growth and development is normal.

1. How is the height standard for children calculated?

Generally speaking, children aged 2-12 can use the following formula to roughly estimate their height:

Height (CM) = (age - 2) x 5 + 85 = age x 5 + 75

Formula for calculating weight according to age:

Infant: Weight in the first six months (kg) = birth weight + age in months X 0.7

Weight in the second half of the year (kg) = birth weight + 6 x 0.7 + (age in months - 6) x 0.5

Weight of children aged 2-12 (kg) = (age) X2 + 12 = age X2 + 8

The evaluation indicators of body weight are as follows:

Severe malnutrition below 60% of standard body weight

60-80% of standard body weight Moderate malnutrition

80-90% of standard body weight Mild malnutrition

90-110% of standard body weight Normal range

>120% of standard body weight Obesity

2. What are the factors that affect children's height?

1. Heredity:

Genetic factors are very important. The characteristics, potential, and trends of children's height development are all affected by the genetic factors of both parents. A child's height is closely related to the height of his or her parents. The general formula for the parents' height can be used to calculate the approximate range of a child's height when he or she grows up.

2. Gender:

The growth and development of boys and girls have their own rules and characteristics. Generally speaking, boys are taller than girls, but at certain age girls may be taller than boys. For example, around 11-13 years old, because girls enter puberty 2 years earlier than boys.

3. Nutrition:

The development of children's height must be supported by a complete supply of nutrients, and the nutrition needs to be balanced. On the basis of ensuring the necessary calories, high-quality protein foods such as fish, meat, eggs, milk, etc. need to be provided. At the same time, various vitamins and minerals, including trace elements, are also needed. Balanced nutrition can maximize growth potential.

4. Disease:

The interference effect of diseases on growth and development is very obvious. Chronic infections often cause weight loss; long-term chronic diseases affect the development of weight and height; endocrine diseases often cause delayed bone growth and nervous system development; congenital diseases have a more obvious impact on growth and development.

5. Maternal pregnancy status:

The development of the fetus in the womb is affected by various factors such as the living environment, nutrition, emotions and diseases of the pregnant mother. If the fetus is slow to grow in the womb, it may affect the child's slow growth after birth and even affect the final height.

6. Living environment:

Living environment plays an important role in children's health. A good living environment, healthy living habits, scientific care, correct education, physical exercise, and complete medical and health care services are all important factors to ensure that children's growth and development reach optimal conditions. In particular, physical exercise can promote growth and development.
