The norm of body weight in children 5 years old. Age standards for weight and height of children according to WHO

As each child develops, it grows and gains weight. Parents who are concerned that the baby grows “correctly” always pay attention to “normal” indicators of body weight and height, focusing on the average data given in the tables of the World Health Organization. When answering the question of how much a child of a certain age should weigh, it should be borne in mind that the body of each person has individual characteristics. That is, in order to understand that everything is in order with the child and he is growing normally, you need not only to compare his parameters with the standard, but also take into account their ratios.

The ratio of the parameters of growth and body weight of the child

The concept of "body mass index" is well known to many parents - especially mothers who are watching their figure. To assess the harmonious development of the child and identify possible deviations in height and weight, you will also need to calculate BMI.

It is important to remember that the norm indicators for a baby differ from those calculated for the adult population. The normal BMI of an adult is no more than 25; for children, a similar index can vary between 13-21. BMI is calculated to diagnose the following conditions:

1. obesity requiring treatment;
2. overweight;
3. slightly increased weight, which is within the permissible range of normal fluctuations;
4. normal weight (see also:);
5. underweight;
6. exhaustion requiring treatment.

Features of the first year of a baby's life

In the first twelve months of a child's life, the indicators of his growth and development are directly related to the characteristics of feeding. In accordance with WHO guidelines, a breastfed child with a birth weight of 3.3 kg (boy) or 3.2 kg (girl) is taken as a reference when developing the table. According to the growth rates, the “starting indicators” are taken to be 49.9 cm and 49.1 cm, respectively.

If the baby was born with less body weight and height (this is often found in children born prematurely, as well as in those born from short parents), then there is no need to worry that after a month or two he “lags behind” from tables.

Until the age of one, it is not the correspondence of height and weight to the table that is decisive, but their change over time. If the child is systematically gaining weight and growing, then everything is in order with him, and there is no reason to panic.

Height and weight of girls

Height and weight of boys

The characteristics of the weight and height of male babies until they reach the age of one are determined according to the same principles as for girls. Of decisive importance for monitoring the condition and development of the child is the monthly weight gain - that is, you need to compare the baby first of all with him, as he was a month ago.

Indicators of a child under 10 years old

The period from birth to reaching the age of 10 is characterized by the rapid growth of the child. However, if up to a year old the baby grew noticeably and “heavier” almost every day, at an older age it will grow a little more slowly.

This is due to changes in metabolism and the growing activity of the baby: the baby spends much less energy and calories on outdoor games than the little one, who has already learned to walk and run, and is now actively learning about the world around him.

Height and weight of a 1 year old baby

If we turn to the average values, it can be noted that during the first year of life, the baby gains about 6-7 kilograms. At the same time, most of the "increase" falls on the first six months of life, when the child adds about 700-800 grams in one month. With proper care, healthy small babies by 6-7 months can “catch up” in weight with their peers who were born with an average body weight.

The weight of a one-year-old child is considered normal if its value is in the range between 8 and 12 kg. In this case, the increase in height will be about 25 cm. The height of a child at 1 year old is approximately 75 cm ± 6 cm.

Height and weight from 2 to 3 years

Between two and three years, the baby is still growing. However, there is less and less quiet rest and meals in his daily routine, and the amount of time devoted to outdoor games is steadily growing. Normally, in the third year of his life, the child will gain about two to three kilograms (that is, it will weigh 11-15 kg) and grow by 9-10 cm.

Height and weight from 4 to 5 years

The average weight of a harmoniously developed 4-year-old baby, according to WHO, is about 16 kg, while a deviation of 2-3 kg up or down is considered a variant of the norm. The growth of a baby of this age is 102-103 cm. By his fifth birthday, a preschooler will recover by about 2 kg and grow by 7 cm.

Height and weight from 6 to 7 years

If you put a healthy six-year-old baby on the scales, and a value from the range of 18-23.5 kg is displayed on the screen, then it fully complies with the standards developed by WHO. By his seventh birthday, an older preschooler (or a younger schoolboy) will become 2-3 kg heavier. According to the growth rate, it will grow by about 5 cm.

Pivot table with parameters from 1 to 10 years

For those parents who are worried about the development of their baby, it will be useful to familiarize yourself with the summary table of height and weight of children, compiled according to WHO. Here are the average height and weight for children of both sexes aged 1-10 years. The parameters of the baby do not have to exactly match the values ​​\u200b\u200bgiven in the table - a deviation of 2-3 kg and a few centimeters in any direction is considered a variation of the norm.

It should also be taken into account that girls grow intensively after 10 and up to 12 years, in boys a jump is observed at an older age - after 13 and up to 16 years. Girls increase in height on average up to 19 years, and boys - up to 22 years.

Indicators for children aged 11 to 18

Indicators that are considered normal at the age of 11-18 years are distinguished by their wide range. This is the period of the onset of puberty, when global changes occur in the body of a teenager. Parents must prepare their growing son or daughter not only physically, but also emotionally.

It should also be borne in mind that it is not recommended to follow a diet for weight loss at this time - a lack of necessary elements in the period before the age of 18 can lead to serious problems in the future.

The norms of height and body weight of children are presented below.

Factors that affect the rate of growth and weight gain in children

The intensity of growth and weight gain depend on the influence of a number of factors. First of all, it is, of course, heredity. If the parents of the baby are not tall and have an asthenic physique, then with a high degree of probability the body weight and height of the child will be similar.

Also among the factors affecting weight and height in children are the following:

1. sleep and rest regimen (it is required that the total daily duration of sleep is age-appropriate);
2. active or passive lifestyle - in active babies, weight and height differ in their proportionality;
3. diet - for harmonious development, it must include all the necessary vitamins, micro and macro elements, be varied;
4. diseases of infectious origin that the child has suffered;
5. the presence of genetic pathologies;
6. features of the course of pregnancy in the mother;
7. features of the birth process.

Deviations from the norm

Significant underweight or vice versa, overweight, as well as too slow / very intensive growth - this is a consequence of the influence of various factors. To identify the causes of serious deviations, you will need to seek advice from narrow specialists - a geneticist, endocrinologist, neuropathologist or gastroenterologist.

Depending on the individual characteristics of the organism, weight correction can be carried out by making changes in diet and lifestyle; it is much more difficult to influence the growth of a child when abnormalities are detected.

Each appointment with a pediatrician in the first 12 months of a baby's life ends with a mandatory measurement of height and weight. If these indicators are within the normal range, then it can be argued that the child is well developed physically. To this end, the World Health Organization, or WHO for short, has compiled the age and weight of children that pediatricians use when assessing the health of babies.

Factors affecting growth and WHO guidelines

Scientists from all over the world are actively studying the factors that affect the height and weight of people. According to recent studies, scientists have come to the conclusion that the weight and height indicators of children under five years of age depend not only on the genetic predisposition, but also on the quality of life, climatic conditions, and the type of feeding in the first two years of life. So, children who receive an artificial mixture as their main food gain weight much more than those who are breastfed.

After analyzing the first WHO tables "height, weight of children under one year", compiled more than 20 years ago, scientists noticed that the norm indicators are overestimated by 16-20%. This is primarily due to the fact that in the 1990s artificial feeding was the most common type of nutrition for children under one year old. In modern days, more and more mothers prefer to feed their crumbs in a natural way. Inflated standards, according to WHO experts, contribute to unfounded recommendations of pediatricians on supplementary feeding of infants, which in turn leads to a complete transition to artificial feeding, as well as overfeeding and, as a result, obesity. According to the WHO, the norms for assessing the height of children and their weight are no longer true. Therefore, in 2006, adjustments were made and new tables were created that are excellent for assessing the development of modern children.

Weight and height of children. WHO table (0-12 months)

The WHO table is considered the most "fair" due to the fact that all parameters in it are assessed as "average", "low" / "high", "below average" / "above average". Thanks to this gradation, it is easy to determine whether the child meets the standards of physical development according to his age.

For a general assessment of growth, it is considered appropriate to take into account weight gain. Based on this, it is customary to refer the following indicators to the norm:

• (first three months) - an increase of 3-4 centimeters to the previous growth. For example, if a child was born 50 cm, then after three months his height will be about 53 cm.
• From three months to six months: the average increase ranges from 2-3 cm.
• From six months to nine months of age, the child grows another 4-6 cm, adding an average of one to two centimeters per month.
• By the year the child increases his height by another 3 cm.

It turns out that in 12 months the child increases his height by an average of 20 centimeters.

Weight gain

The norm of the weight of a newborn child (immediately after the end of childbirth) ranges from 2500-4500 grams. According to WHO, every month the baby should add at least 400 grams. Thus, by six months, the child doubles its original weight. In the following months, the minimum increase should be at least 150 grams. However, when assessing the rate of weight gain, it is necessary to build on the initial body weight of the baby. For example, the increase may be below the norm, provided that the child was born large (over 4 kg), or vice versa, since low-weight babies gain weight more intensively in the following months.

Height and weight of boys

In addition to the factors described above, the combination of which helps to determine the norm, it is worth considering gender, which affects the weight and height of children. The WHO table can display both average height and weight limits for children of different sexes, as well as specific indicators for boys and girls. It is believed that boys, unlike girls, grow faster and gain weight more intensively, so it is worth evaluating their physical development according to the corresponding table.

Height and weight of girls

To describe the physical level of development of girls, there is a separate WHO table “weight, height of girls”. It is believed that girls grow on average until the age of 18, in contrast to boys, whose growth does not stand still until the age of 22. In addition, at the age of 10-12 years, girls grow much faster than boys. The height and weight parameters in the table are averaged. Therefore, in assessing the development of girls, one should not forget about individual characteristics.

boys height and weight chart

It is very important for parents to keep track of weight and the WHO Table and Chart will help loving moms and dads to understand if everything is in order with their child. If the table provides specific data that is the norm for a certain age, then the graph helps to visually see the entire development process.

The graphs below are based on weight and height parameters for boys (blue graph) and girls (pink graph) from birth to 5 years of age. The scale on the left shows the weight or, depending on the graph, the height of the child. Below is the age. The green line, located in the center of the graph and marked with the number 0, is considered an indicator of the norm and corresponds to the “average” rating in the table. The lines of the graph, passing under the numbers -2 and -3, are equivalent to the tabular indicators "below average" and "low". Therefore, lines 2 and 3 are equated to the parameters "above average" and "high".

As you already understood, parents are required to evaluate the weight and height of children. The WHO table in this question will help determine whether the indicators obtained are the norm. However, do not be upset if you notice that the height or, possibly, the weight of your child is short or, on the contrary, high. The main thing is that the weight of your baby should correspond to his height, but at the same time, the indicators should not be critically low or high.

Every mother knows that after birth in a children's clinic, doctors measure the height and weight of her crumbs every month. Indicators must be recorded in the medical card and analyzed. Thus, doctors have in their hands a clear dynamics of the development of the baby in two main parameters. What is the meaning of these measurements? Anthropometric data of children help to diagnose various diseases and pathologies in the early stages of their development.

From birth, it is important to observe the dynamics of the development of growth and weight of the baby.

Height and weight indicators for children - why are they needed?

There are generally accepted norms of height and weight for each age. Any deviation from these standards becomes the first wake-up call, signaling that something is wrong with the baby. Doctors determine a failure if, with good nutrition, the baby does not gain weight well. This can be a signal of developing anemia, rickets, diseases of the endocrine system and immunodeficiency. Too small growth can be a consequence of a lack of growth hormone in the child's body. Being overweight with a moderate diet will be an occasion to check the functioning of the thyroid gland and adrenal glands.

Each child develops individually, so small deviations from the norm are acceptable. Significant, uncharacteristic for children changes in these two indicators will help doctors not only know about the presence of a problem, but also indicate where to look for it. Timely diagnosis helps to prescribe therapy in time and avoid consequences.

Which tables to focus on - domestic pediatrics or WHO?

Until the beginning of the 90s, doctors were guided by the old standards, which had previously been adopted by WHO, when measuring indicators. At this time, the World Health Organization carefully studied outdated standards and drew disappointing conclusions.

It turned out that many anthropometric norms were greatly overestimated. Based on these data, medical specialists in many countries could draw incorrect conclusions about the lag in the development of babies. The consequence of this was the feeding of children with mixtures, which as a result could provoke obesity.

In parallel with the WHO standards in Russia, the use of domestic schedules was practiced, which were compiled on the basis of statistical data in our country. The data in them turned out to be more accurate and helped to make fewer errors. In 1993, WHO carried out a series of statistical analyzes and updated anthropometric data for children. They set new standards that remain relevant to this day.

Features of the first year of a boy's life

Everyone knows that the first years of life are the most important for the baby. They predetermine its further development. In the period up to a year, the child grows at an incredible rate at which the human body never develops again (see also:). It is extremely important for parents to be responsible for the health of the baby during this period - both physical and emotional. Experts divide the age of crumbs up to 1 year into two periods:

• neonatal period;
• infancy period.

The first lasts exactly 28 days from the date of birth, and the second comes to replace it and ends exactly at one year old. The neonatal period is considered the most difficult, because babies are born with not yet fully formed internal organs and tissues.

In the first days from birth, pediatricians pay attention not only to weight and height, but also to the general health of the baby.

These 28 days will be spent by a small life on adaptation in the big world and the final formation of his fragile organism. Pediatricians during the neonatal period pay special attention not only to height and weight, but also to coordination, motor functions, fine motor skills, skin condition, and social activity.

Weight norms for boys up to a year

The table shows the average values. Low and high body weight is not critical, since it depends on many factors, among which a special place is given to living conditions, genetic predisposition and type of nutrition. When the coefficients strongly deviate from normal, specialists may prescribe studies to exclude developmental pathologies.

Breast growth up to a year

According to experts, the baby should grow by 25 cm in the first year, but this figure is highly averaged. It is influenced by a combination of the following factors:

• Nutrition. If the baby receives the necessary amount of nutrients and trace elements, he will grow in accordance with generally accepted norms.
• Heredity. Naturally, tall and large parents also have slightly larger children, and in growth they can add more than their peers.
• Pathologies and diseases. This factor can slow down growth. As we mentioned above, lack of growth hormone, rickets or anemia can slow down the development of the baby.

Normal height for a male child under 12 months of age is shown in the table:

Child development from 1 to 10 years

Over the course of ten years, a child's body undergoes amazing changes. He switches to a full-fledged diet of an adult, his body begins to prepare for a difficult adolescence and hormonal explosions.

The older the child, the less rigid the standards for his anthropometric parameters become. During this period, genetics begins to manifest itself strongly, which causes deviations from the norms.

Weight indicators

The boy's body weight is a labile indicator that quickly responds to changes: nutrition, physical activity, diseases accompanied by weight gain or weight loss. WHO has created special schedules for the development of a child up to 10 years of age, according to which children must fall into the so-called “corridor” of indicators - in this case, the baby develops correctly.

Weight chart for boys under the age of 10:

Growth rates

Growth is a stable parameter for the development of a baby. It determines both the length of the body and the formation of the systems and functions of the body, the increase in organs in size. This indicator is considered the best criterion for determining the state of health of the child. A slow increase in the length of the skeleton contributes to a decrease in the rate of development of the brain, muscles, etc.

Indicators for a baby aged 1 to 10 years are presented in the table:

How does a boy develop from 11 to 18 years old?

The period of puberty for children is difficult: secondary sexual characteristics develop, hormones are actively produced, there is a change in voice, stretching of bones, an increase in the penis and scrotum. Boys gain weight more intensively due to the increase in muscle mass.

Under the influence of hormones, the child does not control his mood. In the period from 11 to 12, the first changes in the body begin. At 13, 14, 15, teenagers are at the peak of their hormonal explosion. By the age of 16-17, and for some only by the age of 18, the situation gradually stabilizes.

The dynamics of the weight of a teenager

The body weight of a teenager should be monitored in the same way as the average weight of a small child. Nutrition during this period should be as varied and complete as possible. The child's body is being rebuilt, which means that he needs more "bricks" for such a construction.

At the age of 11-13, the metabolic process accelerates in adolescents; at 14-16, changes in weight are possible due to hormonal changes. By the age of 17-18, body weight is kept at a set level and may increase / decrease depending on physical condition, nutrition and sports.

The weight parameters are listed below:

It is worth remembering that under the influence of hormones during this period, drastic changes in weight are possible, up to exhaustion or fullness. With such problems, you should contact specialists, because ordinary diets or overfeeding will not be able to help.

Teen growth dynamics

By the age of 12-14, the growth of adolescents gradually reaches a maximum. By the age of 17-18, boys reach 170-180 cm in height - they become young men. The growth process ends at about 18-22 years.

Normal growth in adolescents and young men aged 11 to 18 years:

To determine the development of the baby (normal height and average weight relative to age), special centile graphs are used.

At a pediatrician's appointment, you can hear how the doctor makes an assessment by indicators, calling a number from 1 to 8. There are several tables for calculating the growth rates of boys and their body weight:

• centile plots of average height;
• head circumference charts;
• centile body weight tables;
• chest charts.

The result of calculating the ratio of weight and height is called the Quetelet index. This figure will help determine if your child is suffering from obesity or anorexia. The Quetelet index is calculated using a simple formula: weight divided by height raised to the second power. Use a special calculator, which abound on the Internet. A special index table for babies of different ages will help determine if there are deviations from the norm and how strong they are.

Height and weight of the child are the main indicators of its physical development. That is why immediately after the birth of the baby, it is imperative to measure the weight of his body and the length of the body and continue to weigh himself daily at the same time until discharge from the hospital.

There are many factors that affect the physical development of a child, for example:

• heredity (do not expect a son-basketball player from short parents)
• nutrition (it's no secret that with a deficiency of nutrients, vitamins and minerals, the growth and development of the child slows down)
• physical activity (for example, playing tennis, volleyball, basketball contribute to an increase in height)
• child health (children with chronic diseases often lag behind their peers in physical development)
• psychological situation in the family, at school, lack of sleep, etc.

How to understand what is the norm?

All-Russian Health Organization recommended special tables for matching the height and weight of children, or as they are called, centile tables. At each examination, the pediatrician measures the height and weight of the child, compares the obtained values ​​\u200b\u200bwith the standard indicators. Such tables allow you to identify obvious pathologies, for a more accurate analysis, the doctor calculates additional indicators using special formulas.

Table of weight and height of an infant by months (up to 1 year)

The table shows the average height and weight of infants (under the age of 1 year) by month for boys and girls.

Table of weight and height of the child by years (from 1 to 18 years)

The table shows the average height and weight of a child by years aged 1 to 18 for boys and girls.

Deviations of weight or height from tabular values

There is no need to panic at the minimum discrepancy with the indicated values ​​in the table, and here's why:

1. First of all, tables of height and weight of the child contain benchmarks, then what should ideally be the weight and height of the child, without taking into account many other factors. Sometimes parents of premature babies mistakenly use a standard table for comparison, while there are special tables for assessing the development of children born prematurely.
2. The rate of growth and weight gain is unique for each child.. In the first year of life, babies develop in leaps and bounds. For example, during the period of introducing complementary foods, the weight of the baby may not reach the “norm” due to adaptation to a new type of food, and not because of pathology.

This does not mean that deviations from the norm should be ignored., but it is better to regard them as an occasion to pay attention and consult with a specialist in order to identify possible health problems, or make sure that they are not.

What can be associated with obvious deviations from the norm?

Earlier we talked about minor deviations from the norm and that there is no need to be scared if your child grows and gains weight not strictly according to the table. But what to do if the values ​​of the essential are out of range of acceptable parameters or are they at the intersection of norm and pathology?

The reasons for possible deviations can be divided into two groups:

1. Non-endocrine:

• Constitutional stunting. Or in another way, the syndrome of late puberty. One of the variants of the norm, when the puberty jump occurs later than in other children.
• family short stature. It has a hereditary predisposition, in the family of such children there are relatives with short stature. Growth retardation manifests itself from early childhood.
• Prematurity, intrauterine and postpartum trauma.
• Genetic Syndromes. As a rule, they have many clinical manifestations, one of which is growth retardation.
• chronic diseases cardiovascular, bronchopulmonary systems, gastrointestinal tract, as well as anemia.
• Starvation.
• Taking certain medications.

2. Endocrine:

• Growth hormone deficiency. Biologically active substance, which is the main regulator of the growth process after 2 years.
• Lack of thyroid hormones. More often of a congenital nature, it is clinically characterized by a delay in physical and intellectual development from birth.
• Type 1 diabetes. A disease in which, due to insulin deficiency, the flow of glucose into the cells of the body is impaired, the so-called. "starvation" of cells, as a result, growth rates slow down.
• Cushing's disease (or syndrome). At the same time, the production of hormones of the adrenal cortex, glucocorticoids, is increased, which in large doses leads to a violation of the secretion of growth hormone.
• Rickets. A lack of vitamin D leads to bone destruction and skeletal deformities, which in turn is manifested, among other things, by a decrease in growth.
• Other rare disorders of the endocrine system.

As you can see, there are many reasons.

If the growth of the child is stunted, parents should consult a doctor to identify the causes of short stature and its timely correction.

Remember that for the normal growth of the child, you need a complete, balanced diet with enough vitamins and minerals, as well as dosed physical activity.

With the advent of a baby in the family, happy parents have new worries. The main one is the health of the heir. The main indicators of its harmonious development during a very important period of life are reflected in the table of height and weight of children under one year created by experts. It helps to establish how the process of becoming a baby proceeds, taking into account personal characteristics.

In contact with

When a newborn is born, parents are given the first information about him: what gender he is, how much he weighs, what is the length of his body, as well as information about his general condition. Parents and doctors will closely monitor these values ​​throughout the year, since they are the main indicators of the harmonious formation of the body, and hence general health.

The normal physical dimensions of newborns depend on the timing of birth. When, with a growth of 46 to 57 cm, the baby weighs from 2600 to 4000 g, this is the norm for those who were born on time, that is, at 38–42 weeks of gestation. If the birth was premature, with pathologies, the pregnancy was multiple, then weight and height standards are significantly reduced. For example, if a newborn born in twins or triplets weighs less than 2000 grams, then this value is not considered critical.

Note! If at the time of discharge from the hospital the newborn weighs less than at birth, then this is the norm.

Weight loss in the first days of life is up to 8% of the original value. But the baby is discharged home only after the weight loss stops and the increase begins. The pediatrician monitors the change in these values.

Physical data of a baby up to a year

The initial months of a baby's life path are accompanied by active growth, body weight increases intensively. Measurements of height and weight in children are made monthly, which is the main procedure for determining the normal functioning of a young organism.

Height and weight are always individual, depending on the following factors:

• gender;
• values ​​of the main indicators of the newborn;
• genetic characteristics of parents;
• previous diseases, various infections, sudden dehydration;
• teething, decreased or lack of appetite;
• congenital pathologies or their absence;
• social, everyday components of the upbringing of the baby;
• type of feeding.

Same maternal diet influences degree of height and weight gain in children, the anatomical features of her breasts, individual feeding techniques, as well as the compatibility of various products and drugs when feeding an infant with breast milk.

Measuring the child's weight

Several varieties of tabular forms have been developed to control the physical formation of infants:

1. Standard. Contains the values ​​​​of the main values ​​\u200b\u200bof the development of crumbs up to a year on a monthly basis.
2. An updated WHO table, which indicates the norms of indicators up to a year, taking into account their initial characteristics.
3. Centile, which makes it possible to establish the correspondence of height and weight to the age of babies. The table is designed to analyze and evaluate the indicators of the physical formation of boys and girls separately.

In order to know for sure whether the physiological development of each particular baby is proceeding normally, it is enough to measure the length of the baby's body with a height meter, determine how much he weighs on special medical scales, and then compare the obtained values ​​\u200b\u200bwith anthropometric data.

Standard table

This variety is most often used by medical personnel, because it is convenient, informative, makes it easy to calculate the weight of the child, as well as the length of the body, according to the age of the subject. Based on the given data, it adds 600 g to its original mass.

During the second and third months, when the most intensive formation of the body occurs, the increase is 800 grams per month. Then there is a gradual decrease in the monthly increase in the indicator by 50 grams, which is due to a decrease in the intensity of the development of the baby's body.

During the first month of life, the value of weight gain is less than in the next two months. due to physiological loss of approximately 200 g at birth, which is normal. During the first few days of life, the young body of a newborn actively gets rid of excess fluid. More often this phenomenon occurs during breastfeeding, since the mother’s milk is not yet produced for the first few days, but appears only from the second or third day after birth. A small amount of colostrum, which the baby has been feeding until then, does not contribute to weight gain. Thus, for this month, the same 800 g are recruited, but minus 200 g lost during the first days of existence. The average weight of a child by month is shown in the table.

As for the body length values, the calculations here are even simpler. During the first trimester, the baby grows by 3 cm per month. In the next trimester, the increase will be about 2.5 cm for each month. For another three months, approximately 2 cm are added. During the last trimester of the first year of existence, the intensity of development slows down. The increase in body length to the previous value is reduced to 1 cm monthly. In total, it turns out that during the year the baby grows by about 25 cm.

The norms of weight gain and height in children during the first year, the table shows the average, which is a disadvantage, since there is no clear picture of the individual development of the subject.

WHO tables

This form contains updated information. It reflects the height and weight of the child by months, taking into account the values ​​​​of the quantities at birth. Undoubtedly physical measurements of the baby in dynamics will be different for babies who at birth weighed as much or as little as possible. Since the physical characteristics of infants depend on their gender, the WHO tabular forms are designed individually for boys and girls.

Table of parameters for the development of girls up to a year

The structure and formation of girls has a number of some physiological distinctive characteristics, therefore, the values ​​of the digital parameters of the physical development of their body are somewhat lower than the corresponding parameters of boys.

The baby's weight is monitored monthly. The table of characteristics during the first year of life for girls contains extreme columns with the largest and smallest values. These indicators are critical, so there is reason to recommend contacting specialists.

Table of parameters for the development of boys up to a year

The main height and weight characteristics are contained in the WHO tabular form for boys, the principle of which is similar to the tabular form for girls.

The main thing that you should pay attention to when monitoring the physical measurements of an infant is their monthly increase, that is, only the parameters of the length and weight of the body of a particular examined baby for the previous period of time relative to the present matter.

Boys development

centile tables

Using the data, it is determined whether the height and weight indicators of the baby correspond to his actual age. The physical measurements of the subject are compared with the average figures obtained when examining a certain number of infants of the same age. Each column contains the boundary values ​​of the values ​​of a certain number of children under study. An interval from 25% to 75% is considered normal.

Also very it is important that the measured physical dimensions of the baby belong to the same centile corridor. A deviation of no more than one or two columns is possible. Using this method of examination, one can judge the harmony of the formation of the baby's body. After the research, a conclusion is made about the physical state of the development of the crumbs in points from 1 to 8.

Centric tabular forms of diagnostics of physical development are developed individually for boys and girls.

How to calculate basic physical quantities

Using the child's height and weight calculator, you can independently evaluate the available values ​​\u200b\u200bof the weight and length of the body individually, for each specific case, and also calculate the body mass index. If the physical development of the baby has deviations, the calculator will report possible problems.

Note! The calculator gives the result based on the entered data. If measurements of the length and weight of the body of the baby are made with an error, then the calculation will also not be accurate. .

It is extremely important for each of the parents that their child develops harmoniously. The fact is that minimum or maximum values ​​​​of length and body weight can be found in perfectly healthy babies which depends on many reasons. If at the same time the parameters of the baby fall into one corridor of the centile tabular form or differ by one, maximum two corridors, then this means that the baby develops in proportion, there are no reasons for the parents to worry.
