Age tables of height and weight norms for children. What is normal weight gain in newborns?

Percentage of children with overweight is increasing at an alarming rate everywhere - on average, one in three teenagers and children is now overweight or obese.

Now many children spend little time on training and outdoor games; they spend more time in front of the TV, playing video games or the computer. And in many working, busy families, parents have less free time to prepare healthy home-cooked meals. From fast food to the computer, fast and in a hurry - this is the reality for many families.

Protecting children from excess weight means establishing correct mode nutrition and sports activities, as well as a useful rest together. We must include our children in healthy image life through your own example.

Is your child underweight or overweight?

The World Health Organization (WHO), the US Department of Health, and most countries around the world successfully use BMI - body mass index - to assess excess weight in adults and children, which is based on the ratio of height and weight, and subsequent calculation of the proportion of fat in the human body. The method for calculating BMI was developed by Adolphe Quetelet and for children it provides a special scheme. First you need to calculate the child’s BMI using the general formula:

Body mass index (BMI) calculator using Quetelet's formula

Because children and adolescents are characterized by rapid growth and development, their BMI can change significantly over a short period of time. Therefore, the usual BMI assessment common in adults is not suitable for them. To accurately and correctly estimate a child's body mass index, scientists studied the weight-to-height ratio of many thousands of children. And when it comes to determining whether your child's BMI is normal or abnormal, comparison tables- “percentage curves”, or distribution scales - with averages for children of this age and height will give you the opportunity to understand whether weight adjustments need to be adjusted. This compares your child's body mass index to the average of thousands of other children. This approach takes into account the developmental stages that children go through in certain age groups. For example, if a child has a body mass index higher than 97% of children of the same age, then we can conclude that the child is overweight.
This table contains information on the BMI of adolescents and children of both sexes from 2 to 20 years.

As a result, your child's BMI will fall into one of four categories:

• Lack of weight: BMI below the 5th average (percentage curve);
• Healthy weight: BMI between 5th and 85th average;
• Overweight : BMI in the range between 85 and 95;
• Obesity: BMI falls in the range of 95 or higher.

For children younger than 2 years old, doctors use weight-for-height charts and a careful physical examination.

Table for assessing a child’s weight and height by BMI

At the same time, BMI is not ideal indicator amount of body fat and can be misleading in some cases. For example, a teenager with developed muscles can have a high BMI without being overweight (muscle is added to body weight, not excess weight). In addition, BMI can be difficult to estimate correctly during puberty, during which young people go through stages rapid growth. In any case, it is important to remember that BMI is generally a good indicator, but it is not a direct measurement of the amount of fat in the body.

Bioimpedance analysis allows you to determine the exact percentage of adipose tissue. Using a certain device, a weak, safe electricity, changing its frequency. Various fabrics bodies have different resistance to electric current, thus it becomes possible to calculate what proportion of the body is muscle, and what is bone and fat.

If you are concerned that your child may be overweight or underweight, arrange an appointment with your child's healthcare provider to evaluate their diet and physical activity level and suggest positive changes. Your doctor may also recommend preventing certain diseases associated with being underweight or obese.

Preventing excess weight and obesity

The key to keeping children of all ages at a healthy weight is family lifestyle. This is what is “preached” in the family. Do physical activity And healthy eating family hobby. To make it interesting for children too, let them help in planning useful menu and its preparation, take them with you to grocery stores so that they learn how to choose healthy and proper foods.
Avoid falling into these common nutrition traps:

• Don't reward children for good behavior and don't try to keep them from bad behavior with sweets or treats. Reward or punishment does not have to include food; there are many other effective and the right ways education.
• Don't support the "clean plate policy". Watch for signs that your baby is hungry. Even babies who turn away from the bottle or breast report that they are full. If children are full, don't force them to continue eating. Remind yourself that we should only eat when we are hungry.
• Don’t talk about “bad foods” and don’t completely exclude all sweets and favorite treats from your diet. children's menu. Children are likely to rebel and eat large quantities these harmful products outside the home or when parents are not looking.

conclusions

It is not easy to motivate a child to achieve results; he cannot be “put” on a diet. In its turn, adolescence complicated by the fact that there is a danger of self-rejection, isolation, depression, and anorexia. Once you have determined whether your child needs weight management, we would like to provide some additional recommendations for kids of all ages:

• From birth to 1 year: In addition to the well-known many health benefits, breastfeeding can also help prevent excessive weight gain. And although the exact mechanism has not yet been established, children on breastfeeding, feel their hunger and satiety more clearly, thus protecting themselves from overeating.
• From 1 year to 5 years: to produce good habits better with early years. Help your child establish healthy eating habits by offering a variety of healthy foods. Encourage your child's natural tendency to be active and help him develop.
• From 6 to 12 years: Keep your child physically active every day. Let it be Sport section or outdoor games in the yard. Encourage activity at home - in everyday life homework and in joint games and walks on weekends. Teach your child to choose useful and healthy foods, help him pack his own sandwiches for school.
• From 13 to 18 years old: Teens often gravitate toward fast food, but try to encourage them to eat healthier foods. For example, with baked chicken sandwiches, salads and smaller portions. Teach them how to prepare delicious healthy food and treats at home. Help them maintain physical activity every day.
• All ages: Reduce the amount of time your child spends watching TV, computers, and playing video games. Fight your child's habit of eating while looking at the TV or computer monitor. Try to prepare and offer your child a variety of healthy foods. Try to have breakfast, lunch and dinner with your child together. Encourage children to eat fruits and vegetables at least five times a day, limit sugary drinks and never skip breakfast.

If you eat right, exercise often and include healthy habits into the normal everyday life of your family, you are building a healthy lifestyle for your children, which they can continue to maintain. Explain to them the importance of physical activity and proper nutrition, but be sure to make it a common family habit so that it becomes second nature for each of you.

But above all, let your children know that you love them no matter their weight, and your main desire is to help them be happy and healthy.

The way a baby eats and gains weight is used to judge his health and proper development. Coming to the next routine inspection to the pediatrician, mommy knows that they will begin to weigh the baby and make notes on the card, comparing his indicators with the table approved by WHO experts. The rate of weight gain in newborns is compiled based on the nature of nutrition (natural, mixed or artificial), birth weight, genotype, allowing for slight fluctuations.

Is it worth worrying if the baby does not reach the standard numbers or, on the contrary, exceeds the norm? And is it necessary to supplement the baby's feeding? natural feeding what if he scores poorly?

Normal newborn weight at birth

As soon as a child is born, doctors, after the necessary manipulations, must weigh and measure his height. 4.0 kg, or even 4.2 kg, is considered a reason for relatives to be proud. - this means a strong hero was born.

Doctors think normal weight from 2.6 kg. up to 4.0 kg. with a height of 46-56 cm and their ratio, which allows you to calculate the Quetelet index. For example, the weight of a newborn is 3,350 kg. and height 52 cm. Dividing the baby’s weight by his height, the result is 64. Normal ratio 60 - 70. So the baby is fine.

The initial weight of a newborn depends on its:

1. Health;
2. Genotype. Mom and Dad have a large physique and tall large babies are born, and thin, short mothers most often give birth to small children;
3. Paula. Boys are often born slightly taller and heavier than girls;
4. Mother's nutrition during pregnancy. The passion for sweets and starchy foods leads to the fact that the fetus manages to gain a lot of weight;
5. Availability bad habits. Smoking, alcohol, drugs lead to the birth of sick children with underweight;
6. Physical and psycho-emotional health of parents. If during pregnancy a woman suffered from a serious illness, experienced severe stress or shock, then this will completely affect the baby’s weight.

Important: How many breast milk the child (on breastfeeding) and formula (on IV) should eat -

How much does the baby gain before being discharged?

Upon discharge from maternity hospital Many mothers worry when a newborn, instead of gaining the treasured grams, loses a little.

This happens for several reasons:

1. Loss of fluid. Having begun to breathe, the child’s body loses through the lungs and skin covering fluid reserves that make its passage through the birth canal extremely safe. It is also freed from meconium, the original stool.
2. Establishing a diet. While the baby drinks colostrum in tiny portions, and the mother’s milk is just beginning to flow, the feeding system is being established.
3. Adaptation to new conditions. Small man, like seedlings planted in a garden bed from a greenhouse, begins to actively grow not immediately, but after a while, adapting to its environment.

When discharged from the maternity hospital, the baby's weight is lost by 5-10% of its original weight. From this figure the countdown of the growth rate for each baby begins.

Table of norms for infant weight gain by month (up to one year)

The previous mass is restored within a week, and a significant increase occurs in the first three months. The baby moves little, eats and sleeps a lot.

1. Every day a newborn gains about 20 g in the first month, 25 g in the second month, and 30 g in the third month. Some children gain 2 kg. in the first months. The minimum increase is 460 g, approximately 115 g per week.
2. From 4 months By six months the baby begins to move and sit. Energy expenditure increases, fat reserves are consumed, and weight gain per month ranges from 400 to 600g. From six months to nine months the increase is even less - 300-500 g.
3. Nine months to a year - only from 100 to 300 g. As a result, its weight exceeds the original by almost 3 times.

An approximate table that mommy can use as a guide (by month)

Baby's age, months	Monthly increase, grams	Increase from birth, gr
1	600	600
2	750	1350
3	800	2150
4	700	2850

12	300	6650

• infant 1-6 months: initial weight +800*number of months;
• after six months: initial weight +800*6+400*(number of months after 6 months -6).

Permissible fluctuations in the first year vary +/-1 kg. Children who are on natural feeding, gain about 800 - 1000g. per month for the first three, and then 600-800g.

Newborn weight loss

If the doctor and mom observe serious deviations, you need to take into account factors that contribute to weight loss:

1. Lack of nutrition. When breastfeeding a newborn, a woman may have hypogalactia - low milk production. This is urgently required by any means - from folk remedies, to medications. If it is not possible to return to normal, infant formula is included in the diet.
2. Incorrect application. In the maternity hospital, the nannies show him and make sure he grasps the nipple correctly. Sometimes physiological characteristics buildings do not allow you to fully feed the baby and he, tired of sucking in vain, falls asleep from fatigue (in this case, pay attention to).
3. Application frequency. The average norm is 12 attachments, and the duration of feeding is 15-20 minutes.
4. Stress and illness in the baby and mother affect milk production and the baby’s appetite. If he has suffered from an illness, restoring immunity also requires energy, which entails weight loss.
5. Physical activity. Weight loss is influenced by both infant swimming and massages in the first weeks and months, as well as learning the skills of crawling, sitting, and walking in the future.
6. and incomplete absorption of milk.
7. Neurological pathologies. When due congenital anomaly facial muscles and their improper coordination, the baby cannot suck properly. The feeding process is difficult and difficult for him.
8. Weight loss is sometimes triggered by vaccinations.

Important! An increase of less than 200 in the first month is life-threatening and the baby requires hospitalization. Inadequate nutrition is the cause of the development of serious diseases with serious consequences.

Sudden weight gain in newborns

May cause:

1. Hormonal imbalance. Hormone-based drugs affect lactation and can reduce the mother's milk production. If hormonal disorders occur in a child, and he is constantly gaining weight without slowing down, you should consult an endocrinologist.
2. Overfeeding. This applies to formula-fed infants. Insufficient physical activity, slow learning of new skills, long-term illness, predisposition to allergies - all this can be a consequence of an incorrectly selected mixture and excess feeding.

When the dynamics of weight gain differs significantly from the standards, you should consult a doctor and have your kidneys, heart, and thyroid examined. Pass a series of tests, take an x-ray. The earlier diseases are identified, the easier and cheaper it will be to treat them. When the baby is growing well, gaining weight, is active, is interested in surrounding objects, the color of his urine is transparent or light, he is happy to play and communicate with his family, then there is no reason to worry and there is no need to worry.

With the arrival of a baby in the family, happy parents new concerns arise. The main one is the health of the heir. Its main indicators harmonious development During a very important period of life, a table created by experts reflects the height and weight of children under one year old. 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, the parents are told the first information about him: what gender he is, how much he weighs, how long his body is, as well as information about his general condition. Parents and doctors will monitor these values ​​closely throughout the year, as they are the main indicators harmonious formation body, and therefore general health.

Normal physical quantities newborns depend on the timing of birth. When, with a height of 46 to 57 cm, a baby weighs from 2600 to 4000 g, this is the norm for those born in due date, that is, at 38–42 weeks of pregnancy. If the birth was premature, with pathologies, the pregnancy was multiple, then norms of weight and height 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 maternity hospital the newborn weighs less than at birth, then this is the norm.

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

Physical characteristics of a baby up to one year old

Initial months life path the baby is accompanied by active growth, and body weight increases rapidly. Measurements of height and weight in children are carried out monthly, which is the main procedure for determining the normal functioning of the young body.

Height and weight are always individual and depend on the following factors:

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

Also the degree of increase in height and weight in children is influenced by maternal nutrition, the anatomical features of her breasts, individual feeding techniques, as well as the compatibility of various products and medicines when feeding a baby with breast milk.

Measuring a child's weight

Several types of tabular forms have been developed to monitor the physical formation of infants:

1. Standard. Contains the values ​​of the main development values ​​of a baby up to one year on a monthly basis.
2. An updated WHO table showing the norms for 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 children. The table is designed to analyze and evaluate the physical development indicators of boys and girls separately.

In order to know for sure whether the physiological development of each individual baby is proceeding normally, it is enough to measure the baby’s body length with a stadiometer, determine how much he weighs on a special medical scale, and then compare the obtained values ​​with anthropometric data.

Standard table

This variety is most often used medical personnel, because it is convenient, informative, and makes it easy to calculate the child’s weight, as well as body length, 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. Next comes a gradual decrease in the monthly increase in the indicator by 50 grams, which is due to a decrease in the intensity of 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 because of physiological loss 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 does not yet produce milk for the first few days, but appears only from the second or third day after birth. A small amount of colostrum, which the baby is fed until then, does not contribute to weight gain. Thus, during this month the same 800 g are gained, 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 every month. In the next trimester, the increase will be about 2.5 cm per month. Over another three months, approximately 2 cm are added. last trimester In 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 over the course of a year the baby grows approximately 25 cm.

Age	Body length	Increase in height	Weight	Weight gain
months	cm	cm	kg	kg
0	50–51	-	3,1–3,4	-
1	54–55	3,0	3,7–4,1	0,60

3	60–62	2,5	5,2–5,6	0,80
4	62–65	2,5	5,9–6,3	0,75
5	64–68	2,0	6,5–6,8	0,70
6	66–70	2,0	7,1–7,4	0,65
7	68–72	2,0	7,6–8,1	0,60

11	72–78	1,5	9,5–10,0	0,40
12	74–80	1,5	10,0–10,8	0,35

The table shows average norms for weight and height growth in children during the first year, which is a drawback, since a clear picture does not emerge individual development subject.

WHO tables

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

Table of development parameters for girls under one year old

The structure and formation of girls has a number of certain 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 the outer columns with the largest and smallest values. These indicators are critical, so there is reason to recommend contacting specialists.

Table of development parameters for boys up to one year old

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 to pay attention to when monitoring an infant's physical measurements is their monthly increase, that is, only the parameters of the length and body weight of a particular examined baby for the previous period of time in relation to the present are important.

Boys development

Centile tables

Using the data, it is determined whether the baby’s height and weight correspond to his actual age.

The physical measurements of the subject are compared with the average figures obtained from examining a number of infants of the same age. Each column contains the boundary values ​​of a certain number of children being studied. The interval from 25% to 75% is considered normal. Also very It is important that the measured physical dimensions of the infant belong to the same centile corridor. There may be a deviation of no more than one or two columns. Using this method of examination, one can judge the harmonious formation of the baby’s body. After conducting the research, a conclusion is made about physical condition

Centile tabular forms for diagnosing physical development are developed individually for boys and girls.

How to calculate basic physical quantities

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

Note! The calculator produces results based on the entered data. If measurements of the baby’s length and body weight are made with an error, then the calculation will also be inaccurate .

It is extremely important for each parent that their child develops harmoniously. The fact is that minimum or maximum values ​​of body length and weight can occur in completely healthy babies , which depends on many reasons. If, in this case, the baby’s parameters fall into one corridor of the centile tabular form or differ by one, maximum two corridors, then this means that the baby is developing proportionally, and parents have no reason to worry.

Very short: Z significant growth retardation, may be accompanied by excess weight. A specialist examination is necessary to determine the cause and eliminate growth retardation. Shorty: Oh Stunted growth also sometimes leads to excess weight. Consultation with a physician is recommended. Below average: N He's a short child, but his height is within normal limits. Medium : U The child is of average height, like most healthy children. Above average : A tall child, his height is within the normal range. High : T This growth is rare, is mainly hereditary and cannot indicate the presence of any abnormalities. Very high : T This height can be either normal if you have tall parents, or a sign of an endocrine disease. We recommend consulting with specialists. Height does not correspond to age : Height does not correspond to age - perhaps an error when entering indicators. Please check the data and use the calculator again. If the data is correct, this is a clear deviation from the norm. A detailed examination by a specialist is necessary.

Child's weight

Weight itself, without taking into account height and other data, does not provide a deep assessment of the child’s development. However, the “Low weight” and “Extremely high weight” ratings are sufficient for consultation with a doctor (see weight centile tables for more details).

Possible weight estimates:

Severely underweight, extremely low weight : There is a high probability that the child is suffering from malnutrition. Immediate examination by a doctor is necessary. Underweight, low weight: The child’s body is probably exhausted; a specialist examination is necessary. Less than average: Weight is within the lower limits of normal weight for the specified age. Average : The child has average weight, the same as most healthy children. Larger than average: Extra large: When obtaining this estimate, weight should be estimated based on BMI (body mass index). Weight is not appropriate for age : There may have been an error when entering data. If all the data is true, most likely the child has problems with the development of height or weight (see height and BMI estimates). We definitely recommend consulting with an experienced doctor.

Body mass index

To assess the harmonious development of a child, it is customary to look at the ratio of height and weight - Body Mass Index (BMI). This indicator allows you to most accurately determine deviations in the child’s weight, or, conversely, shows that the child’s weight in relation to height for his age is normal.

It should be understood that this indicator The BMI for each child’s age is different and even more so differs from that of an adult, so this calculator necessarily takes into account both the height and age of the child for the correct calculation (see)

Body mass index estimates:

Severe underweight : Severe exhaustion of the body. Nutritional correction is necessary as prescribed by a doctor. Underweight : Exhaustion. Nutritional correction is necessary as prescribed by a doctor. Reduced weight: Lower limit of normal. The child weighs less than most of his peers. Norm: Optimal height to weight ratio. Increased weight: Upper limit of normal. The child has several more weight than most of his age. In the future, there is a risk of gaining excess weight. Overweight : The child has excess weight. It is recommended to adjust your diet as prescribed by your doctor. Obesity: It is necessary to adjust the diet as prescribed by the doctor and increase the child’s physical activity. Not assessable : Your BMI readings are much higher than normal; you may have made a mistake when indicating your height and weight. If the data is correct, then the child is likely to be severely obese and the help of an experienced doctor is needed.

What a joy when a child appears in the house and with him long-awaited happiness! The baby develops by leaps and bounds, delighting parents and grandparents with his new skills. 1. The height and weight of the child by month, his development as a whole - how can they be described?

He was just a baby, but he has already grown up and recovered. And almost all mothers sooner or later wonder whether their child fits within the norms for newborn weight gain?

The child’s height and weight by month, his development as a whole - how can they be described?

Each baby is individual, we urge you to remember this. Many subjective factors can affect his weight and body length, ranging from heredity, date of birth, general condition health, the mode of feeding it and the nutrition of the mother feeding the child (if he is breastfed)... Even the gender of the child affects its texture.

The table of height and weight of a child up to one year old, which we present below, has been prepared World Organization Health care and compiled taking into account the differences in the development of boys and girls.

Generally accepted standards

As soon as the baby is born, he will be weighed and measured. Normal height is considered to be from 46 cm to 56 cm and weight from 2.6 to 4 kilograms. Children weighing more than four kilograms are considered large and require a little more careful attention from the pediatrician, since in addition to genetically endowed by nature heavy weight and length can be a signal of disorders in the body. The same applies to “low weight” children. Although, as practice shows, few pediatricians base additional attention during examination on the baby’s weight at birth.

Discharge from the hospital will be followed by monthly observations with a pediatrician. During these visits, your son or daughter will be measured and weighed, the growth will be assessed, and a short interview will be conducted about the child’s well-being. past period, they will clarify what the baby eats and, based on the results of the conversation, will give their recommendations. Try not to miss these visits, where you can ask questions that interest you and get a digital basis for arithmetic exercises to calculate whether your child’s weight and height match normal ones.

There are some average indicators that parents and doctors mainly focus on. First, the child's height must correlate with his weight. At 6 months, the averages are 66 centimeters and 8.2 kilograms. If there are deviations in one direction or another, subtract three hundred grams for each missing centimeter, and for more than that, add a quarter of a kilogram to the norm.

Formula for calculating a child's weight

Secondly, height can also be determined approximately by an empirical formula. For each month less than six months, subtract 2.5 units from 66 centimeters. And if the child is older, add 1.5 centimeters. The method is very approximate, since height at birth is not taken into account.

We calculate the weight using the same method. At six months, the average weight of a baby is approximately 8.2 kg. For each month under six months, subtract 0.8 kg from 8.2. And add four hundred grams per movement towards the first year. This calculation can also be questioned as an average and does not take into account the natural loss of body weight and weight compensation, that is, natural physiological fluctuations.

Dear Parents!

We understand all your worries perfectly. The above table fairly fully describes the fluctuations in the weight and height of children.

Please don't panic if any of the numbers approach the "very low" or "very high" column. The child is unique and his increased weight after six months will easily become normal when physical activity increases - after the start of crawling and the first steps. The same is true with height: if the parents are tall, then the child will most likely be ahead of his peers. And the little (in height) daughter, an inch-inch, can be the heir to her petite and slender beautiful mother. Raise your children in joy and let the last columns of the table be just a reason for you to pay attention to the health of your child - if everything is in order and there are no problems, your health is excellent, then continue in the same spirit.

Be healthy, happy and loved - limitless and tableless!
