How tall should you be at 14 years old? Standard height and weight for girls of different ages

Important indicators of the physical condition and health of children are weight and height. It is generally accepted that they depend on human genetics. All children are individual, but excess or little weight may indicate poor nutrition or serious health problems. Very fast or slow growth may be a signal of improper functioning of body systems.

The height and weight of a child is primarily influenced by genetics, but there are many more factors on which these indicators depend

What factors influence height and weight?

The following factors influence height and weight indicators:

genetic predisposition (heredity, ethnic origin);
growth hormones;
transferred to early age diseases;
functioning of the endocrine system;
hormonal surge during puberty;
psychological situation in the family;
nutrition and sleep;
chronic pathologies;
physical exercise;
hemoglobin level;
body weight is directly proportional to length.

What height and weight should the baby be born with?

At birth, the weight of a full-term baby ranges from 2500 g to 4500 g. Boys, as a rule, weigh more than girls. The maximum weight for a baby usually does not exceed 4.5 kg. Average weight – 3.2–3.4 kg. The body length of newborns is 45-54 cm. The average height is 49-52 cm. The body length of girls is usually in the range of 49-51 cm.

As you can see, the range of physical indicators of a child at birth is quite wide. The baby’s data is influenced by various factors: hereditary predisposition, at what stage the baby was born (38-40 weeks), and features of the mother’s pregnancy. It should be said that the same parents can have children with different physiological characteristics.

Height and weight of premature babies

The weight of children depending on the degree of prematurity:

If premature baby healthy, he is quickly gaining height and weight

Body length in children born ahead of schedule, usually less than 45 cm. Their physique is disproportionate, the subcutaneous fat layer is not formed, the sutures of the skull are open, skin filled with blood. Newborns who hastened to be born are nursed in special conditions. At proper care By the first year of life, such children are no different from those born on time.

WHO Child Growth Charts

All children develop at their own pace. However, there are certain norms for weight gain and height that doctors rely on when determining the child’s physical condition. These data are compiled into tables developed by the World Health Organization (WHO). Let's look at WHO tables using the example of girls' development.

Normal indicators in girls under one year old

In the first year of life, children develop most actively. Immediately after birth, newborns can lose up to 300 g in weight. However, in the first three months of life, the baby is able to gain up to 750 g monthly, in the next three months - 700 g, from 7 to 9 months of life - 550 g, 9-12 months – 350 g. Children on artificial feeding, gain weight faster.

Babies grow no less rapidly. The ideal increase in length for babies from 1 to 3 months is 3.5 cm, 4-6 months – 2.5 cm, 7-9 months – 1.5-2 cm (see also:). From 9 months to one year, children grow another 1 cm per month. The average weight of a child per year is in the range from 8900 to 9600 g. Body length is from 74 to 76 cm.

On average, children are born with a weight of 2.9-3.5 kg and a height of about 52 cm

Table of weight norms from 0 to 12 months:

Based on the data, a weight indicator for a one-year-old baby of 7.9-10.1 kg is considered ideal (we recommend reading:).

The weight of one-year-old girls can vary greatly - there are “skinny” ones, and there are “chubby” ones.

Low and high weight is not critical; it can be caused by genetic predisposition or characteristics of pregnancy. If your baby's readings are beyond low or high, doctors will conduct additional tests to rule out health problems.

Children's age from one to 10 years

In the period from one to 10 years, a child’s musculoskeletal system is formed and strengthened, and the functioning of all internal organs is improved.

With insufficient nutrition and improper distribution of physical activity, children may develop various diseases. Therefore, it is just as necessary to monitor the norms at this age as in infancy.

Monitoring the height and weight standards of school-age girls is as important as in infancy

Development of girls from 11 to 18 years old

Ages from 11 to 18 years are considered adolescence. At this time, intensive changes occur in the children's bodies. This is especially noticeable in appearance. Chubby baby can turn into the perfect girl, and the skinny woman needs to get in shape. Such changes are caused by hormonal changes in the body. It is necessary to understand when such changes are normal and when to sound the alarm.

Consider the weight table for teenage girls:

Age, years	Weight, kg
Age, years	short	lower limit of normal	norm	upper limit of normal	high
11	24,9-27,8	27,8-30,7	30,7-38,9	38,9-44,6	44,6-55,2

The height of high school girls can vary greatly: from 150 to 175 cm

Is it possible to calculate a child's height based on the parents' height?

There are several formulas for approximate calculation of a child’s height in relation to the height of his parents:

To calculate a girl's height (RD), you need to add the father's height (RO) with the mother's height (RM), multiply by 0.51 and subtract 7.5 cm. The author of this formula is unknown.
Another formula belongs to the Czechoslovakian V. Karkus. RD cm = (RO cm*0.923 + RM cm)/2.
Dr. J. Hawker suggested calculating height as follows: RD = (RO + RM)/2 – 6.4.
Formula of Smirnov and Gorbunov: RD = (RO + RM -12.5)/2 ± 8.
Another formula calculates height based on the data of a child per year (CA). RD = RG + 100 cm – 5 cm.

Periods of intensive growth in children: when do leaps occur?

Girls develop at the fastest rate from 10 to 13 years. This is explained by active puberty.

During this period, the teenager’s body receives a major hormonal shock. During puberty, the future girl can grow by 8 cm per year. Her figure will also change significantly - weight gain or loss is possible.

If the child is too tall

Child height is considered a hereditary factor. If in the family tall parents, then the baby will be tall from childhood. However, too much deviation from the child’s age norms can be a signal that there are significant problems in his body. In addition to early puberty, high growth in children it can be caused by:

high content of growth hormones;
obesity;
chromosome pathology;
pituitary tumor;
Marfan syndrome;
dysfunction of the pituitary gland.

What to do if the child is very small?

The short stature of a child, if it is not due to a genetic predisposition, should also cause concern among parents.

If parents notice that the baby is not growing well and is not gaining weight, they need to consult a specialist.

The doctor will study the history of his height gains, examine the child, and analyze the diseases he has suffered. If the parents' doubts turn out to be justified, a thyroid examination is prescribed. To exclude rickets, the child is prescribed an ultrasound. In parallel with these studies, the pediatrician should prescribe tests to check the blood for growth hormone and hemoglobin levels. Sometimes a child's bone age is examined using bone x-rays.

A teenager’s body weight is an important indicator of his dynamics physical development. Excess, as well as lack of weight, have an extremely negative impact on the dynamics of the formation of all systems and organs of the human body. Especially for readers of Popular Health, I will consider how much a teenager should weigh at 14 years old.

Normal weight and height for a teenager are calculated and periodically adjusted by specialists from the World Health Organization. To assess the correct development of boys and girls, specialists use special tables that take into account both the age and gender of the child.

For 14-year-old boys, a normal body weight should be considered to be between 42 and 56 kilograms. For girls it should be considered the norm the following indicators- from 48 to 58.

At this time, the body weight of girls may exceed the body weight of boys, since the period of puberty and the formation of a woman’s body begins at a slightly earlier age.

Puberty is a special part of the life of any person, regardless of gender. At this time, the human body undergoes significant changes of a qualitative nature. It is during these years that the formation of secondary sexual characteristics and increased development of the genital organs occur.

Moreover, during puberty, increased growth of the human body occurs, which inevitably affects his body weight. Over the course of just a few years, a person’s body weight increases by about 20 kilograms, which is quite significant, especially in absolute values.

Current trends

Unfortunately, a teenager with normal body weight in recent decades is rather an exception to the rule. Obesity is a real scourge of humanity, regardless of the person’s age or gender.

The above is true for representatives of most countries with developed economies and social spheres. The higher the level of income, the more people prone to obesity.

It is currently impossible to reverse the current trend. The development of obesity is actively promoted by changes in the lifestyle of a modern teenager (frequent and prolonged stay at the computer or smartphone instead of physical activity), as well as the availability and popularization of unhealthy diets (fast food and all kinds of processed foods).

Modern children absolutely cannot stand healthy food. Getting a child of any age to eat porridge or soup is sometimes almost impossible. But all kinds of hamburgers, chips, and sweet soda go with a bang.

Underweight and overweight

A child’s high body weight, as well as low weight, may indicate the presence of a pathological process. Of course, minimal deviations, both in one direction and the other, cannot be considered as an illness, but no less, doctors recommend paying close attention to such a teenager.

When talking about excess or underweight, experts most often cite the following reasons for the development of such conditions:

Incorrect nutritional (nutrition-related) habits;
Nutritional imbalance;
Changes in psychological background;
Hormonal pathology.

Entrenched incorrect nutritional stereotypes can hinder a person not only in childhood, but also in adulthood. It is not so easy to break habits that have been formed over the years and have been repeatedly fixed in the human consciousness. For this reason, it is necessary to accustom a child to proper nutrition from childhood.

Nutritional imbalance was mentioned above. Changes in the psychological background can lead to both suppression and increased appetite. Personal troubles, failures at school, rejection by peers, all this may not lead to stressful situations. Children, just like adults, have a very difficult time coping with stress.

Pathology of a somatic nature can also lead to the development of deficiency or excess body weight. For example, many hormonal diseases can be accompanied by obesity, sometimes quite pronounced.

What to do?

If deviations from normal indicators are not significant, and the teenager does not make any complaints, there is no need to show much concern. Most likely, the reason for the change in body weight is nutritional in nature.

All that is needed is to normalize the diet, after which the child’s body weight should come into full compliance with the norm. If, despite all efforts, a teenager's weight continues to deviate in any direction, it is necessary to visit a doctor as soon as possible.

If there are significant deviations in body weight, a visit to the doctor is required. If there is severe underweight, the child may have anorexia. Girls are especially susceptible to this condition.

If you are severely obese, diet alone may not be enough. Teenagers need to lead active image life, but it is better to do this under the supervision of doctors or specialists in the field of physical therapy. In addition, it is necessary to exclude hormonal pathology.

Conclusion

The child's body weight should be within the normal range. A significant deviation from normal limits should be considered an alarming condition requiring medical intervention.

Every mother knows that after birth in a children's clinic, doctors measure the height and weight of her baby every month. The indicators must be recorded in the medical record and analyzed. Thus, doctors have clear dynamics of the baby’s development in two main parameters. What's the point of these measurements? Anthropometric data of children helps to diagnose various diseases and pathologies at the early stages of their development.

From birth, it is important to monitor the dynamics of the baby’s height and weight.

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

There are generally accepted standards for height and weight for each age. Any deviation from these standards becomes the first alarm bell, signaling that something is wrong with the baby. Doctors determine a failure if, despite 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 much short stature may be a consequence of a lack of growth hormone in the child’s body. Excess weight with a moderate diet will be a reason to check the functioning of the thyroid gland and adrenal glands.

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

Which tables should we refer to – domestic pediatrics or WHO?

Until the early 90s, when measuring indicators, doctors relied on the old standards that had previously been adopted by the WHO. At this time, the World Health Organization carefully studied outdated standards and came to disappointing conclusions.

It turned out that many anthropometric standards were greatly overestimated. Based on these data, medical specialists in many countries could draw incorrect conclusions about developmental delays in children. The consequence of this was the supplementary feeding of children with formula, which as a result could provoke obesity.

In parallel with WHO standards, Russia practiced the use of domestic charts, 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 mistakes. In 1993, WHO conducted a series of statistical analyzes and updated data anthropometric indicators 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 a baby. They are the ones who predetermine its further development. In the period up to one year, the child grows at an incredible speed at which the human body never develops again (see also:). It is extremely important for parents to take responsibility for the baby’s health during this period – both physical and emotional. Experts divide the age of a baby up to 1 year into two periods:

neonatal period;
infant period.

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

In the first days after 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 the little life adapting to big world and the final formation of his fragile organism. Pediatricians during the newborn period pay Special attention not only height and weight, but also coordination, motor functions, fine motor skills, skin condition, and social activity.

How smaller child, the faster he gains weight (in percentage), and by the first year of life a boy can weigh from 8 to 13 kilograms (see also:)

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 diet. When coefficients deviate greatly from normal, specialists may order studies to exclude developmental pathologies.

Baby growth up to one 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 required amount nutrients and microelements, it will grow in accordance with generally accepted standards.
Heredity. Naturally, tall and large parents also have slightly larger children, and they can gain more in height than their peers.
Pathologies and diseases. This factor can slow down growth. As we mentioned above, a lack of growth hormone, rickets or anemia can slow down the baby’s development.

If a child has a complete and balanced diet, he grows and develops in accordance with generally accepted standards

Normal height for a male child under 12 months of age is presented 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 adult diet, his body begins to prepare for the difficult adolescence period and hormonal explosions.

How older child, the less stringent the standards for its anthropometric parameters become. During this period, genetics begins to strongly manifest itself, which causes deviations from the norm.

Weight indicators

A 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 child development charts up to the age of 10, according to which children must fall into the so-called “corridor” of indicators - in this case, the baby develops correctly.

Children of the same age cannot have the same weight (everyone has different genetics, nutrition, physical activity, health), but there is a weight table in which everyone should fall into the “corridor”

Growth indicators

A stable parameter of a child’s development is height. It determines both the length of the body and the formation of systems and functions of the body, the increase in size of organs. This indicator is considered the best criterion for determining the child’s health status. 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 child aged 1 to 10 years are presented in the table:

By observing the dynamics of a child’s growth, it is possible to provide adequate criteria for assessing his health.

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, voice changes, bones stretch, enlargement of the penis and scrotum. Boys gain weight more rapidly due to increased muscle mass.

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

Teenage weight dynamics

A teenager's body weight should be monitored in the same way as an average weight. small child. Nutrition during this period should be as varied and nutritious as possible. The child’s body is being rebuilt, which means it needs more “bricks” for such construction.

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

Weight parameters are shown below:

Age	Body weight, kg
Age	Very low	Short	Average	High	Very tall
11 years	26	28	34,9	44,9	51,5
12 years	28,2	30,7	38,8	50,6	58,7
13 years	30,9	33,8	43,4	56,8	66
14 years	34,3	38	48,8	63,4	73,2
15 years	38,7	43	54,8	70	80,1
16 years	44	48,3	61	76,5	84,7
17-18 years old	49,3	54,6	66,3	80,1	87,8

It is worth remembering that under the influence of hormones during this period, sudden changes in weight are possible, up to exhaustion or obesity. Such problems should be addressed to specialists, because regular diets or overfeeding will not help.

The weight of a schoolchild depends on many factors; it is important for parents to monitor the development of the child so that there is neither thinness nor obesity

Growth dynamics of a teenager

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

IN adolescence The height and weight of children can either change quickly or, on the contrary, stand still. Parents are often concerned if their child’s physiological indicators differ from their peers. To be calm about the development of your child, it is enough to know the general statistical norms for height and weight in adolescents. It must be remembered that the growth spurt in girls usually occurs earlier - at 10-12 years, and in boys - at 13-16. Nutritional characteristics, physique, heredity - all this affects the child’s size and can be very different between two teenagers the same age. You should only worry if the indicators are near the lowest and highest indicators of the tables. In this case, you should consult your doctor.

Height to weight ratio in adolescents

The human body does not grow throughout its entire life. For boys, this process stops at 19-22 years old, for girls - already at 17-19 years old. Until this age, height and weight increase unevenly. A particularly noticeable jump occurs in the first year of life and at the initial stage of puberty. In girls it begins at 10-12 years old, in boys - at 13-16 years old: boys begin and finish growing later than girls.

There is a certain average weight and height for each age period, small deviations from which are quite acceptable. Jumps in anthropometric parameters are individual for each teenager. One grows evenly and gains weight over several years, while the other literally stretches 15-20 cm in a matter of months, and then the process slows down sharply.

Except age characteristics Other factors also influence the ratio of height and weight:

hereditary predisposition;
daily routine and lifestyle;
food habits in the family;
characteristic physique;
features of nationality, race, nationality.

How to create a calorie deficit for weight loss - calculation formulas

Calculation of averages

To find out if a teenager is the right weight and height age standards, these parameters must be taken into account together. This is due to physiological processes occurring in the body. A growth spurt is often preceded by rapid weight gain. In this case, by checking the tables, you can see that the height norm is met, but the weight goes beyond its limits. This is normal and there is no need to worry. Having taken measurements after 1-2 months, it becomes clear that the situation has stabilized.

The opposite situation happens, when a teenager looks too thin despite his height. There is no need to worry if your child does not have chronic illnesses or loss of appetite. By the end of puberty, the proportions will return to normal.

When measuring weight, it is worth taking into account bone mass. There is a so-called “heavy bone”. Most often, a similar phenomenon is observed in boys: such a child will weigh more than normal, although there are no visual signs overweight No.

Also, one should not confuse the volume of a body with its mass. Sometimes children who look plump weigh less than their peers who play sports: this happens because fat is four times lighter than muscle. When checking the table, a well-fed teenager falls into the average column. And the weight of an athlete whose body has developed muscles will go beyond its limits.

Measurement Rules

Before comparing anthropometric data, you need to obtain it correctly. There are certain rules for measuring weight and height:

Indicators of human growth measured during the day will differ by 1.5-2 cm. In the morning it will be larger, and in the evening it will be smaller. This is due to the fact that after sleep the body is maximally elongated; in the evening, the distance between the vertebrae decreases under the force of gravity and the height measurement shows lower values.
The position in which the growth rate is recorded is very important. This is done on a hard, level floor or a special stand, from which the countdown is in centimeters (zero mark). The person being measured stands barefoot, pressing his back, buttocks, heels, head and shoulder blades to a perpendicular, flat surface. Without pressing, lower the height meter bar or ruler onto your head and mark the resulting height level. Then measure the distance from zero to the top mark.
Weight is measured in the morning, before breakfast. By the evening, a person’s weight can increase by 1.5-2 kg from food. It is important to remember that clothes and shoes can weigh quite a lot, so it is advisable to remove them. Make sure the scale is placed on a level and solid surface. The child must stand still during weighing, without bending or moving.
When monitoring the dynamics of height and weight, measurements should be taken at the same time of day.

If these rules are followed, reliable data is obtained that can be used as a guide.

Average Tables

Height and weight values for people of all ages are presented by the World Health Organization (WHO) in the form of anthropometric (centile) tables. In addition to the average indicator, they have graphs with deviations up and down.

The ratio of height and weight in adolescents is quite arbitrary. Having received indicators that at first glance differ from the norm, you should take into account all the factors influencing anthropometric data:

The average height and weight of the child should be within the green and blue graphs. These figures correspond to the average height and weight of children of this age.
Values that are within the yellow and green columns are also normal, but indicate a tendency for the child to lag in height or weight.
Values that are within the blue and yellow columns are also within normal limits, but indicate a tendency for the child to be ahead in height or weight.
Values that are within the red and yellow columns are already considered low and high, which can be explained both by the characteristics of the child’s growth and by diseases associated with hormonal imbalance (in most cases, of an endocrinological nature). A pediatrician will help you understand and identify the cause.
Height and weight values that are beyond the red border in both directions are evidence of pathology child's growth. Such children must receive advice from medical specialists.

Weight of boys from 11 to 17 years (kg):

Height of boys from 11 to 17 years (cm):

Weight of girls from 11 to 17 years (kg):

Height of girls from 11 to 17 years (cm):

Conclusions are drawn based on whether the indicators correspond to age. For example:

With an average height of 176 centimeters, normal weight boys range from 75 to 80 kilograms; for a woman of the same height, the normal weight will be only 65-70 kilograms.
If a woman is 162 centimeters tall, her normal weight varies from 50 to 55 kilograms; men of the same height will weigh 60-65 kilograms.

At the same time, for guys, a height of 162 cm is insufficient, and for a 17-year-old girl, 178 cm is excessive. From the above example it is clear that when calculating the normal ratio of height and weight, one must take into account a variety of factors and aspects.

What can cause developmental disabilities?

If a deviation from the norm is detected in the ratio of weight and height, a mandatory visit to the pediatrician is recommended, followed by following his prescriptions, recommendations and examinations.

Serious causes of violations of the relationship of physical indicators can be:

early or late puberty in a teenager;
disorders of the hypothalamic-pituitary system;
thyroid diseases;
suffered severe or chronic diseases of other body systems;
genetic abnormalities;
family lifestyle.

Modern laboratory tests will help identify the causes. Most deviations are eliminated after taking specially selected medicines and balancing hormonal levels. Even the impact on the body of the lion's share of genetically determined diseases with the help of medicine today can be stopped or weakened.

Lifestyle plays an important role in the proportional increase in height and weight in adolescents. With the right approach, it allows all body systems to work without failures:

And a little about secrets...

The story of one of our readers, Inga Eremina:

I was especially depressed by my weight; at 41, I weighed as much as 3 sumo wrestlers combined, namely 92 kg. How to remove excess weight fully? How to cope with hormonal changes and obesity? But nothing disfigures or makes a person look younger than his figure.

But what can you do to lose weight? Laser liposuction surgery? I found out - no less than 5 thousand dollars. Hardware procedures - LPG massage, cavitation, RF lifting, myostimulation? A little more affordable - the course costs from 80 thousand rubles with a nutritionist consultant. You can, of course, try to run on a treadmill until you go crazy.

All parents, without exception, are interested in the health and normal development of their children. In this regard, many will be interested in a table of the ratio of height, weight and age of children, as well as methods for determining this parameter.

What is accepted as the norm?

The norms for the ratio of height and weight in children are very relative and depend on the individual developmental characteristics of each child. In our country, the average height for males is 178 cm, and for females 164 cm. At the same time, girls grow to approximately 17-19 years old, and boys until 20-22. Growth is considered to be most intense during puberty from 10 to 17 years, and girls grow especially quickly at 10-12 years and boys at 13-16.

The key factors influencing the normal ratio of height and body weight in children under one year of age and older are normal nutrition, adherence to a sleep schedule (at least 8 hours), and physical activity.

When determining the correct height-to-weight ratio for a child after 11 years of age, certain factors must be taken into account. IN adolescence a growth spurt occurs. Some people begin to grow more actively at the age of 11 and reach their maximum by the age of 13, while for others intensive growth is just beginning at the age of 13-14.

The jump is explained by puberty. Thus, during this period, calculate perfect ratio height and weight in adolescents can be especially difficult, so the determined values cannot be taken seriously, especially if they deviate slightly from the norm.

What should you know about height measurements?

To determine the ratio of height in children under and after one year, you need to know certain rules. For children under two years of age, body length is measured, that is, when the baby is lying down. At the age of 3-4 years and later, height is measured, that is, the child should be standing at this moment.

In general, height is considered one of the key indicators taken into account when assessing the development of children. It is usually measured monthly. We will still look at what the height-to-weight ratio should be for teenagers, but first we will look at the generally accepted estimates for height:

Obviously undersized. This assessment is given to children who are stunted. Sometimes this phenomenon is accompanied by excess weight. in this case, you will have to consult a pediatrician.
Short. This assessment also assumes stunting, sometimes accompanied by excess weight.
Below the average. Short children are not uncommon. In this case, growth is within normal limits, but is at the lower limits.
Average. The child has average height, characteristic of most fully developing children of a similar age.
Above average. The child is tall, but falls within the normal height-to-weight range for 3-7 years or older.
Tall. Such children are rare and are mainly a matter of heredity, but not deviations from the norm.
Very high. In such children, everything may be normal or there may be endocrine disorders. You need to consult a pediatrician.

How is body weight determined?

For the ratio of height and weight in young men after 15 years or in children younger age Body weight must be determined. When weighing, the doctor can give the following assessments:

Significant underweight. There is a high probability of exhaustion of the body, so consultation with a specialist is necessary.
Low weight. It may be a matter of exhaustion of the child’s body, so an examination is recommended.
Less than average. Her weight is within normal limits, but remains at her low levels.
Average. Most children receive this assessment.
Above average. In this case, weight must be recalculated using body mass index.
Overpriced. If the weight is clearly higher than normal, the doctor calculates the BMI and makes recommendations on how to normalize the weight-to-height ratio for a boy or girl. , we told.

What is BMI?

Body mass index expresses the ratio of height and weight in children under 12 years old or adolescents 13-17 years old. Using this indicator, deviations are determined, after which you need to take care of normalizing the situation.

You should be aware that BMI values for children 2-5 years old and 13-16 years old will be very different, so age is always taken into account when calculating it. When determining the ratio of height and weight in children from 2 to 15-17 years old using the body mass index, doctors make the following estimates:

Clear lack of mass. The body is very exhausted, so you need to adjust your diet.
Lack of mass. It’s probably a matter of exhaustion, that is, nutritional correction is needed.
Reduced weight. Weight is at the lower limit of normal.
The norm is the ideal ratio of height and weight for an infant or older child.
Overweight. Your weight is at the upper limit of normal and there is a possibility of gaining extra pounds.
Obesity. You need to adjust your diet according to the recommendations of a nutritionist and increase physical activity.

Height to weight ratio in infants under one year of age

Children may be born with different lengths body and weight, so it is difficult to determine the ideal height-to-weight ratio for girls and boys at this moment. On average, weight indicators for healthy babies range from 2.6-4 kg, and body length from 46 to 57 cm. Pediatricians are guided not only by weight and ruler readings, but by their ratio. Of course, if the height is large and the body weight is small, this is a deviation.

Before the age of one year, the weight-to-height ratio is strictly checked by a pediatrician. He monitors the baby’s development, determines whether the body receives enough nutrients and whether there are any violations.

Determine yourself normal attitude Height to weight for a child under one year old can be found in the table. It should be appropriate for the child's gender, since boys usually outperform girls in infancy.

Development of preschool children

After a year, you need to continue to monitor your weight-to-height ratio until you are 5-6 years old, and you need to do this just as carefully. To measure your baby's height at home, you will need a simple stadiometer that can be attached to any wall. In this case, the child needs to take off his shoes and straighten so that the shoulder blades, buttocks and heels touch the vertical surface. After this, you need to record the growth at the top of the head.

If your child's height to weight ratio is normal at 3-5 years old, don't worry about anything. If deviations are detected, their degree must be determined. For example, if the difference with the norm does not exceed 10 percent, you don’t have to worry, but if the value deviates more, you need to consult a doctor. As for weight, it is determined using good electronic scales. You need to measure your body weight on an empty stomach and after using the toilet to get the most accurate readings.

Starting from the age of 3, the height to weight ratio will change, as the baby will gain about 2 kg annually. By the age of seven, the child’s weight should double compared to the first year. To determine the normal ratio of body weight to height, you can use a simple formula: A + 2B.

A is the weight of a one-year-old child;
B - age;
2 average annual weight gain during the period from 3 to 7 years.

If a baby weighed 9 kg at one year old, then at 6 years his weight should be 21 kg. Using a similar formula, height is determined: D + 5E.

D - child's height;
E - age;
5 - increase in height per year.

A 5-year-old child who was 75 cm tall at one year old should have a height of 100 cm. You must remember that during moments of intense growth the child will need help. He may become clumsy, so you need to provide your baby with physical activity and a normal diet.

Height to weight ratio at school age

Finally, let’s figure out what the height-to-weight ratio should be for teenagers aged 14-17 years and for younger children aged 7 to 13 years. At this age, spasmodic development and the most active growth are observed. The muscular system is improving, so achieving an ideal body weight to height ratio can be difficult. Muscles do not have time to develop as quickly as growth increases. In this regard, teenage disorganization and peculiar angularity are the norm and do not require special adjustments.

The optimal ratio of height and weight in girls and boys aged 14-17 years largely depends on the following factors:

playing sports;
balanced diet;
complete rest;
hereditary factors;
way of life in general.

A table of the ratio of height, weight and age for children, schoolchildren, teenagers 14 years old and older will allow you to determine normal indicators the child’s weight and, if necessary, adjust them.
