Child growth standards, what are the child growth standards?

The development of children within the age of 3 should be specifically evaluated from the aspects of height, weight, head circumference, gross motor, fine motor, language, and social behavior, so there is the term child health care. However, for older children, it is simple to judge nutrition and development from height and weight.

Child growth reference data.

2. Formulation method: the international common LMS method.

Third, the main technical content of the reference standard:

1.Main indicators: weight, length height, weight for height, head circumference, body mass index (BMI).

2.The standard for growing eggplant is expressed in the form of a number, and the expression is expressed in percentiles.

Standard charts (numerical tables, graphs).

1) Growth standard chart: monthly age interval is used, expressed in percentiles.

Percentile criteria include: 3rd, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97th

2) Chart range: weight by age (0 83 months), height by age (long) (0 83 months), head circumference by age (0 72 months).

Length of weight (45 cm to 105 cm), height of weight (65 cm to 125 cm) and age of BMI (0 to 83 months).

The so-called method of using the percentile method to evaluate height is to take out 100 boys or girls in a certain age group, and rank them according to the number of centimeters of height from small to large, with the small percentile value being low and the large percentile value being high, and finding the value of a certain percentile (with p as the code), which is often divided into the percentile. P3 is the 3rd percentile, P50 is the 50th percentile, and P97 is the 97th percentile. In medicine, according to the percentile method, the rapid growth and development of human socks are divided into 5 grades:

Those ranked between the 25th and 75th are middle, those ranked between the 75th and 97th are above the middle class, those above the 97th are considered the upper class, the 25th and the third and above are considered the middle and lower class, and those below the 3rd rank are inferior and belong to the short stature.

If a child's height is not within the percentile curve of the projected target height, it is necessary to look for reasons that are hindering their growth and development. Therefore, it is helpful to use the growth criteria to determine whether a child's height is normal, taking into account the height of the parents. For children in puberty, it is also necessary to combine the development of sexual characteristics, bone age and other comprehensive indicators to judge.

There is a set of standards for boys and girls.

Weight, height, head circumference, chest circumference, teeth development.

The standard of normal development of children is mainly from 5 aspects, weight, height, head circumference, chest circumference, and tooth development. Generally, the weight of newborns is about 3 kg, but with the different nutritional intake of the mother, there are also higher or lower than this weight, and the baby's weight increase law in the future is, weight (kg) is equal to multiplied by 28.

The height growth is regular, and the average height increases by about 8 cm per year. The head circumference of the baby will grow by 12 cm in the first year of life, and then the speed will slow down. Bust circumference is about 32 cm at birth, head circumference is larger than chest circumference before 1 year of age, and bust circumference increases faster than head circumference after 1 year of age.

At the age of 1 3 months, the baby will gain kilograms per month, at 4 6 months, it will probably increase kilograms per month, and at 7 to 12 months, the weight gain per month is kilograms. By the age of 1 2 years, the weight gain of the whole year is between kilograms.

In order to promote the growth and development of the baby, the first thing is to ensure a balanced nutritional intake, and the usual diet should be varied, so that the baby can get enough protein, vitamins and calcium. If your child has a picky eating habit, parents should find ways to help them improve.

Growth and development

Today's parents pay special attention to the growth and development of their babies, especially the big movements in infancy and early childhood, after all, no one wants their children to lose at the starting line. In fact, there are certain standards for children's growth and development, as long as they are within this standard range, it means that the development is normal.

It is very important for children who are growing and developing to get a good night's sleep. If your child gets enough and regular sleep every day, not only will he be in good spirits, but he will also be able to reduce the chance of getting sick. Exercise keeps people's bodies in a healthy state, and the same is true for children.

Parents should take their babies outdoors more often, let them run around and jump around, and breathe fresh air.

Today's children's living standards are much higher than before, and their intake of nutrients is becoming more and more diversified, so compared with the previous generation, today's children's physical development data has exceeded a lot. It doesn't make much sense to go back to the previous set of standards. Therefore, we need to know the latest child development standard comparison table.

First of all, the height of the child is mainly affected by the genes of the parents, but it can also grow taller through acquired efforts. The height and weight scale for boys from 1 to 5 years is :, while the height and weight scale for girls is from 1 to 5 years

75cm, secondly, the child's basic development stage is 4-6 years old before school age, and the absorption of calcium at the age of 6 is very important for future growth. Because at this time, people's bones are in the reserve period, and they need to supplement about 800 mg of calcium every day. Some children with picky eating and anorexia may appear to be shorter than their peers if they do not consume enough calcium.

Finally, every stage of a child's development is not to be ignored. If the foundation of one stage is not laid, it will affect the growth and development of the next stage. Therefore, parents should pay attention to supplementing their children with the nutrients needed at each stage and let them maintain sufficient sleep time every day.

Develop a good habit of exercising regularly.

From prenatal to pregnancy to childbirth, the child actually goes through a lot of problems before it can be born healthy. When born, the general normal growth and development should be carried out from the individual, normal growth and development, in the neonatal period, generally speaking, the pound is the standard of normal growth and development, when gradually growing up to 1 year old, the average height of the child will grow to 75cm, and the weight will grow to about kilograms. When 2-3 years old, growth and development will decline, not as fast as before 1 year old, generally 4-5 pounds, when 3 years old growth and development will be further slowed down.

But there is a formula that reminds parents to make a simple judgment on height and weight, that is, age 2 8, which is a different body mass index for each age group, so you can use this formula to compare, but there will eventually be children who look particularly good, and there are also children who are relatively poor. If the child's growth and development are poor, it is necessary to communicate with the pediatrician or the doctor of the pediatric department to find the reason for the growth and development. If the growth and development is particularly fast and exceeds the normal standard, it is still necessary to carry out proper control, not that the fatter the better, and childhood obesity is also a common problem in recent years.
