Growth and Development Between Ages 15 and 18 - What to Expect?


Active growth

Usually girls begin to actively grow at the age of 9-10 years. In this case, the peak growth rate occurs at 11-12 years, which coincides with intensive sexual development. In boys, active growth begins a little later (about 11 years) and reaches its maximum by 13 years. This is why in high school girls are taller than boys at first, and then this changes.

During a growth spurt, guys normally manage to grow by 9-10 cm per year, and girls - by 7-8 cm per year. This explains the fact that men are usually 10-12 cm taller than women. The growth rate slows down towards the end of puberty. This is due to the fact that the growth of cartilage, which is located at the ends of long tubular bones, practically stops.

Growth - norms and pathology in premature babies

In premature infants, it is necessary to determine the correspondence of physical development to the gestational age. Development corresponds to gestational age when assigning weight, body length, head circumference, weight-height coefficient from the 10th to the 90th percentile.

Intrauterine growth retardation is diagnosed with consistently low indicators with two or more measurements below the 3rd percentile - with height less than 48 cm, weight less than 2200 g.

All children with intrauterine growth retardation must be observed by a pediatric endocrinologist.

After 43 weeks, assessment of physical development is carried out according to charts for young children, but taking into account the corrected age (the difference between the actual postnatal age in weeks and the weeks of gestation missing to full term).

The highest growth rates of premature babies are in the first 3 months of life (3.5-5 cm per month).

  • In the first half of the year, the monthly increase in height is 2.5-5.5 cm,
  • in the second half of the year - 0.5-3 cm.

The total increase in height for the year is 27-38 cm.

The average height of a newborn child by year is 70.2-77.5 cm.

The body weight of premature babies in the 1st year increases 6-7 times; an increase of 20 g/kg body weight at birth is adequate. Anthropometric indicators are equal to those of full-term children aged approximately 2 years, but with a body weight of up to 1500 g. indicators are lagging behind.

How to get taller

A healthy, nutritious diet, regular exercise, and good, adequate sleep help achieve maximum growth. Most children do not need to take any additional nutritional supplements because all essential nutrients are obtained from food.

You should be wary of any products that promise to make you taller. In some pharmacies you can find tablets whose labels say “growth stimulant” or “growth hormone”, but growth hormone is a medicine that should not be taken without a doctor’s prescription.

Sometimes a doctor may prescribe such a drug, but only for strict medical reasons, such as proven severe growth hormone deficiency. HGH has certain side effects: it can cause diabetes and fluid buildup in the brain (hydrocephalus).

The Problem of Tall Teens

It is not uncommon for one student in high school to stand out for his large height compared to other classmates. The reasons for this phenomenon may be the following factors:

  1. Heredity - most often, if a boy or girl has one of the parents who is tall, then this is passed on to the child
  2. Klinefelter syndrome
  3. High production of growth hormones
  4. Acromegaly
  5. Early maturation of adolescents
  6. Marfan disease
  7. Excessive fat mass

The tallest girl is seventeen years old

A reason for concern for parents may be that their child is much shorter than his peers. So, the reasons that a teenager is not growing much or has stopped growing altogether may come from the following sources:

  • Genes - no wonder short parents have small children
  • Various pathologies - only doctors can diagnose them
  • Lack of vitamins in the body of a teenager
  • Bad habits (smoking, alcohol, drugs, unhealthy lifestyle)

Bad habits affect the growth of teenagers

Smoking has a negative impact on the normal development of adolescents

Is it possible to predict growth?

The best way to predict growth is to draw up and carefully study the so-called growth chart or graph. The pediatrician notes on the graph the age and height of the child at a given time and monitors its changes. Since doctors know very well how boys and girls should grow, it will not be difficult for them to assess these parameters.

Future growth can also be calculated mathematically. But to do this, you must know the height of both parents, since the main parameters of the body depend 90% on genes. There are several formulas that allow you to roughly estimate the height of an adult. For example:

  • Girls' height = (mother's height + father's height - 17) / 2
  • Boys' height = (mother's height + father's height + 17) / 2

You can use a special calculator that allows you to calculate your child’s height online.

Child's weight

Below you can see the indicators of a child’s body weight depending on age (from 2 to 10 years), tables compiled by WHO in 2006.

During visits to the pediatrician, your child will be weighed, height, and other measurements taken. Weighings are performed on gram-accurate scales. A baby up to one year old is weighed naked to accurately determine his weight.

Weigh-ins let you know how your little one is gaining weight, and you can compare your little one's performance to the average child weight. Each baby develops differently, the most important thing is steady growth.

What influences the lag/advancement of physical development

When monitoring a child's development, pediatricians pay attention to child growth charts.

average height of a child
It is important to monitor the dynamics of the child’s development and record data to compare them with the norm

Normal limits are set within 25%, 50%, 75%, but if the development dynamics are within 3% and 97%, that is, very low and very high, respectively, but this may signal the presence of pathology.

But often children with such indicators develop just as normally as those with indicators of 25%, 50%, 75%.

Everyone’s body is individual, and the growth dynamics of children are different for everyone. If in one month of life the child has not grown as indicated in the table, then there is no need to worry in advance.

The pediatrician, first of all, will look at the growth of the parents and ask how quickly they grew in childhood, since the genetic information embedded in the child manifests itself.

With the onset of puberty, intensive development begins . The time at which maturation began influences physical development. This is due to the released hormones.

If puberty is premature, then the child will stop growing before the age of 18, but if it began late, then the person will lag behind his peers in development, but the opportunity to catch up with them is great.

Growth hormones are produced by the pituitary gland - an endocrine gland . A lack of growth hormone in the body is called hypopituitarism. Consequently, growth slows down in this condition.

Another important hormone is thyroxine, which is secreted by the thyroid gland. The lack of this hormone leads to slower growth and development in general. This disease is called hypothyroidism. Many chronic diseases can also slow development.

An important factor is the way the mother behaved during pregnancy. Alcohol, smoking, and poor nutrition negatively affect the development of the fetus, as a result of which the child may be born premature.

Developmental delay is characterized by genetic diseases. For example, a disease where girls grow very slowly is called Turner syndrome . Marfan syndrome is characterized by tall height, long arms and legs.

The child's short stature is also due to lack of food. In order for a child to grow well, he needs to receive all the necessary substances and microelements.

It is important for every parent to know how their child is developing, what the norms are for the weight and height of children under one year old. What time do children start walking?
