Table of the rate of growth and weight of a child under one year (WHO)

It's not a secret for anyone that the growth andbody weight of each child. They depend on many factors: individual and hereditary. The World Health Organization has developed certain standards, under which it "drives" the newborn. And for this there is a special table. The norms of growth and weight of the child, presented below, will help parents to determine whether their crumbs are developing correctly or not.

Optimal performance

The table of the norm of growth and weight of a child up to a year is the same.That is, it is designed for virtually all newborn babies. Indicators in it are average, they refer only to a healthy category of children. It is clear, if the baby was born prematurely or is very ill, then at first he will lag behind his peers. It takes time to catch up with them. Therefore, while parents pay attention to indicators is not worth it.

In addition, not all children have a tablethe rate of growth and weight of a child up to a year. WHO, when drafted, focused more on the Caucasoid race and the characteristics of the inhabitants of the Americas. Accordingly, much depends on the nationality: for Chinese kids, these sizes can be gigantic, for black children - too small. In addition, one should take into account the growth and weight of parents, the individual characteristics of the organism crumbs. Despite this, adults are obliged to keep the indicators under control in order to find out the problems in the development of the child in time.

WHO standards

First, parents should always be on the lookoutchild. They are responsible for the health of the baby. Secondly, determining the size of the newborn in the first year of life is the responsibility of the pediatrician. Every month at the reception the doctor fixes the indicators and gives advice to young mother and father. The norm of weight and height of children (WHO table) is the simplest and most popular way to determine if everything is good with your baby, whether it needs to correct the diet and regime of the day. If in one month the child has not added much, do not worry - in the next 30 days he will "catch up" with him. But when the backlog is observed and for two months, it is worth turning to an experienced specialist.

Norms of the World Health Organizationdesigned for children of the first year of life. In addition to mass and length of body, they include the volume of the baby's head and the circumference of his chest. At such a tender age, these indices are important, because with their help it is possible to determine the development of bone and muscle mass in children. At this age, the musculoskeletal system of the baby is only being formed, therefore, noticing the strong discrepancies with the figures of the table, it is necessary to immediately ring the alarm.

Index of "fattening"

With its help you can evaluate the physical statechild. The index of "fattening" characterizes the level and volume of the subcutaneous fat layer. This figure is relevant when the crumb turns six months old. It is at this age that doctors determine whether a young organism receives enough nutrients or not. The index is calculated using the following formula: the circumference of the shoulder (just below the BCG vaccination) is multiplied by 3, we add to this value the circumference of the widest part of the shin and the volume of the thigh (in the upper third), we subtract the height of the baby in centimeters from the received amount. Normally, the figure is from 20 to 25. If the result is lower, this indicates a lack of fattening of the child, if higher - for an excess of food.

Remember that not only is the norm of weight and growth importantchild: the table takes into account the size of the baby's head. Of course, the circumference of the skull can be individual. However, a rapid increase in volume or, on the contrary, its barely noticeable growth indicates serious problems associated with various pathologies.

Example of calculating the norm

It is taking into account the average weightnewborns and experts were compiled a table of the rate of growth and weight of a child up to a year. WHO determined the starting point of weight, from which it is necessary to repulse when determining the normal body weight of the baby. According to doctors, the standard is 3 kg 100 grams. If the youngster in the first month of life in the norm should score 600 grams, then the coefficient is calculated thus: 3100: 600 = 5.67. This is the constant that you must use for individual calculations.

Let's say a baby was born with a weight of 3 kilograms.To determine how much he should gain for the starting 30 days of life, you need to divide the body mass by a constant: 3000: 5,67 = 530. That is, just as many grams should appear in the baby in the first month of life. Remember that this formula can not be applied to babies born prematurely, or to those who have excess body weight. The figures that the table shows the growth rate and the weight of the child, in any case, are approximate. Only an experienced physician can calculate individual indicators specifically in your case.

Table of growth and weight of babies

It shows how much the baby should addin the first year of life. At the same time the weight and height for boys and girls is the same, but the volumes of the chest and head are different. The reason is that for the mass of the body, the sexual sign in the first year of life does not matter, instead it affects the circumference of parts of the body in connection with the physiological characteristics of the organism.

Table of the rate of growth and weight of a child up to a year

Age in months	Weight gain (g)	Increment in growth (cm)	Head circumference (boys)	Head circumference (girls)	The volume of the chest (boys)	The volume of the chest (girls)
1	600	3	37,3	36,6	36,3	36
2	800	3	39,2	38,4	39	38,1
3	800	2,5	40,9	40	41,3	40
4	750	2,5	41,9	41	42,8	41,8
5	700	2	43,2	42	44,3	43
6	650	2	44,2	43	45,4	44,3
7	600	2	44,8	44	46,4	45
8	550	2	45,4	44,3	47,2	46
9	500	1,5	46,3	45,3	47,9	46,7
10	500	1,5	46,3	46,6	48,3	47,3
11	400	1,5	46,9	46,6	48,7	47,7
12	350	1,5	47,2	47	49	47,7

It turns out that your baby in the first year of life should recover by 7 kilos 200 grams and grow by 25 centimeters. As for the circumference of the head and chest, the table shows the initial figures.

Growth

As you can see, the most active increase in height and weightthe baby is observed in the first three months of life. Further, it slowly decreases to optimal values. The growth of the youngster depends on many factors, the main one of which is heredity. In addition, it affects the belonging of the baby to a specific sex, nationality, as well as the quality and quantity of nutrition of the mother. The body length of newly born babies normally ranges from 45 to 55 centimeters. Most intensively, the baby grows in the first three months - almost 3 centimeters each month. Further increase slows down: from 3 to 6 months - 2.5 cm, from 6 to 9 - 2 centimeters. On average, the child "stretches" by 25 centimeters per year: his height is 75 cm.

Further, the weight and height norm is slightly modifiedchild. Table in 2 years will look absolutely different. So, in a year and a half the height of the baby is 82 cm, in 2 years - 88 cm, in 2.5 - 93 cm, in 3 - 97 cm, in 3.5 years - 101 cm and more. The acceptable difference is 6 centimeters both in one and the other direction.

The weight

The methods by which you can calculate the weight necessary for crumbs are many. So, in the first six months of life, a formula is used:

Weight of body = weight at birth (g) + 800 N, where N is the number of months.

Further, the rate of body weight gain is reduced, and therefore the equation is substantially more complicated:

Initial mass = birth weight + 800 x 6 (increase in the first six months) + 400 (N-6), where N is the number of months (from 6 to 12).

The formula can be simplified as follows:in six months the average weight of the baby is 8200 g, for all subsequent months 400 g are added, and for each "extra" is subtracted for 800 g. Weight is a dynamic indicator. Children born with a lot of weight, the entire first year of life, look larger than peers. The one who was premature, catching up with the other children by 2 years. As for further development, the table for the growth rate and the weight of a child under 3 years old looks like this: in a year and a half the baby weighs about 11 kg, in 2 years - 12.2 kg, 2.5 - 13.3 kg, 3 - 14 , 3 kg, in 3,5 - about 15 kg. The allowable difference is 2.5 kg.

If something went wrong ...

Parents are required to know what the norm of weight and heightchildren. The table, girls and boys in which are separated only in the category of circles, shows that they first gain the body weight - regardless of gender. And if up to six months the increase is active, then it goes down further. The explanation is simple: after 6 months, the babies begin to sit, crawl and walk. Accordingly, they consume more calories and energy, while fewer kilograms are postponed. A very small increase indicates insufficient nutrition. Usually such a problem occurs in infants: the mother may have a decreased secretion of breast milk. Solve it in two ways: stimulate the production of additional amounts of fluid or supplement karapuza mixtures.

It should be noted that excess weight, toogives a lot of trouble. The table of the norm of growth and weight of the child shows that in a year the kids should weigh about 10 kilograms. If they scored extra 2 or 3 kg, it's hard for them to move, crawl, walk, run. Such crumbs are more prone to allergic reactions, they have a longer and heavier cold. Overweight is most often observed when the infant is on artificial feeding.

What should I look for?

In most cases, girls developfaster than boys. Therefore the table of the rate of growth and weight of the child can partially be modified: the baby can gain a little more than the fixed standard indicator. You do not need to worry. A doctor's advice is necessary only when the deviation is very significant. After birth, you need to determine the foundation on which you will make your calculations. In this case, they will not be the weight of the baby when born, but the mass of the crumbs during discharge - after staying in the hospital, he loses a little, which is the physiological norm.

The older the child becomes, the greater histhe indicators are leveled, approaching the generally accepted, standard. Of course, you can be very upset at the matinee in the kindergarten that the peer of a son is above his head. Dont be upset. If the carapace is healthy, active, observes the regime of the day and eats well, there should be no cause for concern.
