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 and body weight of each kid have their own. They depend on many factors: individual and hereditary. The World Health Organization has developed certain standards, under which it "drives" the newborns. 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 seriously 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 on all toddlers calculated table of the rate of growth and weight of the child 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 body crumbs. Despite this, adults are obliged to keep indicators under control, in time to detect problems in the development of the child.

WHO standards

First, parents of the child should always be on the lookout. 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 you need to adjust 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 lag is observed and for two months, it is worth turning to an experienced specialist.

The norms of the World Health Organization are designed for children of the first year of life. In addition to mass and length of body, they include the volume of the infant'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 state of the child. The index of "fattening" characterizes the level and volume of the subcutaneous fat layer. This indicator is relevant when the crumb turns six months old. It is at this age that doctors determine whether a young organism gets 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 an insufficient fattening of the child, if higher - for an excess of food.

Remember that not only the weight and height of a child is important : 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, conversely, its barely noticeable growth suggests serious problems associated with various pathologies.

Example of calculating the norm

Taking into account the average weight of newborns, the experts also compiled a table for the rate of growth and weight of a child up to a year. WHO has determined the starting weight point, 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 is in the first month of life, it should normally be 600 grams, then the coefficient is calculated as follows: 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 into 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 carapace should add in 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 body mass 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.

It turns out that your baby in the first year of life should recover by 7 kilograms 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 body height and weight in a 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 chief one being 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 every 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.

Then the norm of weight and height of the child is slightly modified. The table in 2 years will look absolutely different. Thus, in a year and a half the height of the baby is 82 cm, in 2 years - 88 cm, 2.5 - 93 cm, 3 - 97 cm, 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, use this formula:

Body mass = 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 significantly more complicated:

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

Simplified formula can be brought to this scheme: in six months the average weight of the baby - 8200 g, for all subsequent months add 400 grams, and for each "extra" is deducted for 800 g. Weight - a dynamic indicator. Children born with a lot of weight, the entire first year of life, look larger than their 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 is the norm of the weight and height of children. 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. This is explained simply: after 6 months, the babies begin to sit, crawl and walk. Accordingly, spend more calories and energy, while less is put off kilograms. 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 overweight also causes 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 have gained extra 2 or 3 kg, it is difficult for them to move, crawl, walk, run. Such crumbs are more prone to allergic reactions, they have a longer and heavier cold. Excess weight is most often observed when the infant is on artificial feeding.

What should I look for?

In most cases, girls develop faster than boys. Therefore, the growth rate and weight of a child can be partially 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. At the same time, it will not be the weight of the baby when it comes to light, but the mass of the crumbs during discharge - after staying in the hospital, it loses a little weight, which is a physiological norm.

The older the child becomes, the more its indices are leveled, approaching the generally accepted, standard ones. Of course, you can greatly afflict the matinee in the kindergarten the fact that his son's peer is above his head. Dont be upset. If the carapace is healthy, active, observes the regime of the day and eats well, you should not have any cause for concern.
