How much should a person weigh between 2 and 20 years old?

Growth standards for girls 11-12 years old

According to the World Health Organization, girls at the age of 12 must meet certain height standards. They can be found in the table.

The table shows that these indicators can range from very low to very high. This is not considered a pathology, since children develop according to an individual pattern. For example, if your daughter is 152-160 cm tall, this is quite normal. She is somewhat ahead of her peers, but this does not indicate health problems.

Only a specialist can suspect any pathology in a child, based on data obtained during a visual examination of the patient, as well as during a laboratory examination of the patient.

The health and physical development of children always worries parents. If children worry them because they often get sick, then older children make mothers worry about other reasons - underweight or obesity in teenagers, short stature. This is exactly what we will talk about in the article, i.e. Let's talk about the norms for height and weight of adolescents and what factors they depend on. To make it easier for you to monitor your child’s development, we will also present a table of the height and weight of adolescents.

Peculiarities of growth of adolescent children

Today, there are the following standards for human growth: men - 175 cm, women - 165 cm. However, these are eliminated indicators, and there are exceptions to all rules. For example, a teenage girl at 16 years old can be 175 cm tall, i.e. like the average adult male. And there is nothing special about this, because her height could have been inherited from her tall parents. However, the growth of a teenager, the table of which we present below, has its own standards, and both doctors and parents are guided by them.

Active growth of a teenager begins with the onset of puberty - puberty. Girls have a growth spurt earlier than boys - at 10-12 years. Boys begin to mature at the age of 12-14. The cessation of active growth in girls occurs at 16-18 years, and in boys - at 18-20. It is important to note that during puberty, a child grows so quickly that his body does not have time to build muscle and accumulate fat tissue. This is why during the period of active growth children lose weight, which actually makes parents worry about the teenager’s weight. But the opposite can happen - children first gain weight and then begin to grow. This fact also alarms mothers - when the child becomes overweight and does not grow at all. But you need to understand that everything has its time, and in order not to worry again, pay attention to the ratio of the teenager’s height and weight.

Factors influencing the growth of a teenager

Before we tell you how much a teenager should weigh and what his height should be, let's find out what this depends on and why children develop differently. As we have already said, the growth of a child largely depends on the genetic factor, i.e. for example, parents of shorter than average height are unlikely to have tall children and vice versa. The same applies to adolescent weight standards. If a child has both parents or one of them has a tendency to be overweight, then it is not surprising if he is overweight. Therefore, those who have very tall or obese parents may no longer fit into the height and weight standards for adolescents. The height-to-weight ratio of adolescents may be outside the norm in other cases. These include:

• Features of puberty. For some children, this period may begin at 8-9 years old, and therefore they begin to grow earlier than many of their peers. And those children whose onset of puberty is delayed, on the contrary, are stunted. But it won’t be long before they catch up with those who went ahead.
• Hormonal disorders in the body. This may be dysfunction of the organs that produce growth hormones - the pituitary gland and the thyroid gland. Parents will not be able to identify the pathology on their own. Therefore, if you suspect strong deviations from the norm, you should contact an endocrinologist.
• Chronic diseases - anemia, cystic fibrosis, rheumatoid arthritis, pyelonephritis and others.
• Complications during intrauterine development associated with infection of the fetus, poor nutrition or bad habits of the mother.
• Poor living conditions: poor nutrition, family scandals, beatings.
• Genetic diseases - Turner, Marfan, Down syndrome and other diseases.

These are only the main factors that influence the growth of a teenager, but in fact there are many more reasons for deviations from their norms. These causes must be identified and eliminated as quickly as possible, while there is a period of active growth. Nowadays, many diseases, including genetic ones, are successfully treated; the main thing is to notice the problem in time and contact a specialist.

What does a child's weight depend on?

With the onset of puberty, some teenagers begin to rapidly lose weight, while others begin to gain weight. It is during adolescence that special attention must be paid to a teenager’s weight. The table gives average values, and therefore there may be deviations from the norm. And in order to understand why a teenager’s weight does not correspond to the table, it is necessary to take into account many factors that influence weight. Extra pounds in older children appear for the following reasons:

• Genetic predisposition to obesity.
• Poor nutrition, when teenagers not only eat a lot, but also use addictive foods for food, for example, fast foods.
• Lack of physical activity.
• Hormonal disorders.
• Some chronic diseases that are accompanied by obesity.

The reasons for a teenager's obesity should be identified and eliminated as early as possible, because... many children remain overweight throughout their lives.

While some teenagers are embarrassed by their excess weight, others suffer from their thinness. During puberty, many children grow very quickly, and everything they previously accumulated is distributed throughout the body. Therefore, children stretch out and quickly lose weight. But after the period of active growth ends, everything returns to normal. However, parents should pay attention to their teenager's weight if it deviates too much from the average. The normal weight of a teenager in the table is indicated as an average, and you just need to focus on it. The reasons for thinness may be the following:

• Malnutrition. Many teenagers do not want to waste their time on breakfast and lunch, eating only one meal after school. Some of them refuse to eat so as not to gain weight (a problem for girls). And a lack of calories causes weight loss.
• Diseases of the gastrointestinal tract - gastritis, enterocolitis and others.
• Hormonal disorders.
• Bad habits.

It is important to remember that during active growth a child needs more healthy food than before. Some doctors recommend multivitamins for teenagers to help the teenage body develop correctly. If you notice significant weight changes in your child, take action immediately. You will see the weight according to the table for schoolchildren below.

Teen Height and Weight Charts

All parents need to know what the height and weight of a child depends on in order to prevent the consequences of a possible problem in time. If you monitor your child’s health, he is unlikely to have any difficulties. However, as you understand, not everything depends on the parents, and the child needs to be periodically examined by doctors. Well, now you can measure your student's height and weigh him to check if he is developing normally. And the following tables will help you with this.

Normal weight indicators

In addition to height, you should also definitely pay attention to what weight a child has at 12 years old. How much should a girl weigh? You will find normal indicators for a teenager in the table.

Normally, a girl at this age should weigh approximately 36-45 kg. If you are underweight, you should reconsider your daughter’s diet. Perhaps she lacks high-calorie foods.

If your body weight is too high, it is important to choose a diet that excludes sweet and high-calorie foods. In addition, it is necessary to monitor the child’s sufficient physical activity. You can enroll the girl in a sports section, dancing, or spend leisure time with outdoor games together.

Weight gain workout program for teenagers

Strength training for teenagers in the gym has its own characteristics:

1. Weak muscle corset (especially the lumbar region)
2. The musculoskeletal system is not ready to work with heavy weights
3. The cardiovascular system is subject to age-related changes and needs special attention

All these factors dictate certain requirements for the training program:

1. Each lesson requires exercise for the abs and lower back, which strengthen the muscular corset of the back.
2. Almost all exercises are performed lying down or sitting to minimize the compression load on the spine during forceful impact

For the same reasons, the program does not include barbell squats and deadlifts.

Instead, safer basic exercises are used - leg press in a machine and pull-ups on the bar.

Next, consider an example program:

Causes of excessive height in children

When assessing a child’s parameters, it is very important to pay attention to the ratio of height and weight. Adolescents with a body length above average and weight, accordingly, will exceed average norms. In addition, we must not forget about heredity. Tall parents tend to have tall children and vice versa. As for the pathological causes of too high growth, they can be as follows:

• Hyperthyroidism is a disease accompanied by excessive production of sex hormones.
• The onset of premature puberty under the influence of any provoking factors.
• Excessive synthesis of adrenal hormones and androgens.
• Congenital adrenal hyperplasia.
• True gigantism.
• Syndromes – Marfin and Klinefelter.

Regular exercise can also influence this criterion. This applies to volleyball, basketball, handball.

One of the most common reasons for increased growth is the constitutional acceleration of body length in modern adolescents. In addition, such children develop rapidly at the mental level.

Norms of weight and height of babies up to one year

A table of height and weight for children under 12 months is used more often, since in infancy it is most important to track growth in indicators. The norm for boys is:

For girls, these standards will look like this:

Height and weight gain may slow down one month and speed up the next. The indicators depend on the baby’s maturity, type of feeding, and overall health. The influence is exerted by the lifestyle of the parents and the activity of the newborn. It is important to remember that the numbers are averaged and are assessed by the pediatrician only as part of the child’s general medical history.

What is infantile gigantism?

This concept refers to a condition characterized by an excess of somatotropic hormone in the child’s body. This pathology is quite rare today. Its main symptoms include too rapid growth of the child. Moreover, this can be observed both in preschool and school age.

Gigantism often develops against the background of a previous illness at an early age. This refers to hydrocephalus or encephalitis.

The figure in children with gigantism has characteristic outlines. They tend to be awkward, angular and somewhat awkward. Patients with this pathology are susceptible to various diseases, including viral and bacterial, to a greater extent than their peers.

Development of girls under 14 years of age

The height and weight of girls between one and three years does not change so rapidly. By school age, after 6 years, a significant increase in height is observed. The second jump occurs in the range of 8.5 – 12 years. At first, the main growth occurs due to the elongation of the limbs; from the age of 11, the torso elongates more. The most intensive growth in adolescence is observed from 10 to 13 years, this is associated with puberty. The total increase of this jump is 36 -38 cm.

In preschool and school children's institutions, students are annually checked for compliance with standards; if they deviate from them, the child is sent for a medical examination, and recommendations are given for correcting nutrition. Tables approved by WHO have the following meanings:

Causes of stunting

It often happens that teenagers lag behind their peers and their body length does not correspond to generally accepted standards. Factors that provoke this disorder include the following conditions:

• Heredity. As already mentioned, genetic predisposition is important. If the parents are not tall, most likely their child will also have a short body length.
• Having a baby prematurely or having too low a birth weight. According to medical statistics, premature babies catch up with their peers by approximately 2 years. If this does not happen at a given age, then, as a rule, in the future such children will lag behind their peers.
• Various endocrine diseases can cause a lasting delay. They are accompanied by a violation of the synthesis of thyroid-stimulating hormone, which affects the functioning of the pituitary gland.
• Poor nutrition. Short stature is often a consequence of poor or unbalanced nutrition of the child. The lag can also provoke low appetite, which occurs against the background of diseases of the digestive system or metabolic disorders.

In most cases, the short stature of a teenager is only a consequence of the constitutional characteristics of the body. To correct this condition, doctors recommend following a diet, maintaining a proper daily routine and exercising. This allows you to increase body length and lead a full lifestyle.

If the lag is caused by certain diseases, observation by a specialist and competent drug treatment are required.

Physical exercises beneficial for children 12 years old

Many parents often worry about their children being too short or, for example, overweight. Basic sports exercises will help correct your posture, strengthen your muscles and improve your immunity. So, what sports are suitable for a teenager:

• Swimming, athletics, cycling, basketball, volleyball, handball - these activities will help increase the length of the child's body.
• Exercises on parallel bars and horizontal bar.
• Yoga and stretching exercises are ideal for girls - they will help strengthen muscles and improve their figure.
• Tennis (table and large). This type of physical activity can be done by the whole family.

Race walking will help boost immunity and improve the functioning of the respiratory system. This sport is perfect for overweight teenagers.

A well-chosen daily routine, proper and balanced nutrition, sufficient physical activity and a friendly atmosphere in the family will help raise a healthy, strong child and raise a full-fledged personality. Take care of your children and be happy.
