7.2.1. Increase in Height

The most conspicuous change during puberty is the sudden increase in height. At this time the long bones, that is, the bones of the arms and the legs elongate and make a person tall.

During puberty, individuals experience notable physical changes, one of which is a sudden increase in height. This is primarily due to the elongation of long bones, such as those in the arms and legs. These changes occur rapidly, especially in adolescents, leading to noticeable growth spurts.

Imagine the way a plant grows taller when it receives sunlight and water—during puberty, our bodies are like plants receiving growth hormones that enable our bones to grow and reach new heights.

The following chart gives the average rate of growth in height of boys and girls with age. The figures in columns 2 and 3, give the percentage of the height a person has reached at the age given in column 1. For example, by the age 11, a boy has reached 81% of his probable full height, while a girl has reached 88% of her full height. These figures are only representative and there may be individual variations.

A chart presents the average growth rates for boys and girls at different ages. It indicates the percentage of their expected full height reached by that age. For instance, at age 11, boys typically reach 81% of their adult height, while girls reach 88%. This highlights that individual growth trajectories can vary based on genetic and environmental factors.

Consider a race where runners are at different skill levels. Just like in that race, some children will reach their full height more quickly than others, while others might take a longer path to their final height.

There is no need for Paheli to worry. All parts of the body do not grow at the same rate. Sometimes the arms and legs or hands and feet of adolescents look oversized and out of proportion with the body. But soon the other parts catch up and result in a proportionate body.

During growth, not all body parts develop at the same pace. For example, hands and feet may seem disproportionately large compared to the torso. This is a normal occurrence during puberty, as eventually, the rest of the body will grow and achieve a more balanced and proportionate appearance.

Think of a new car being built—parts may arrive at different times, and it may look incomplete until all parts are installed and everything is properly aligned.

You must have noticed that height of an individual is more or less similar to that of some family member. This is because height depends on the genes inherited from parents. It is, however, very important to eat the right kind of food during these growing years.

Height is largely influenced by genetics, meaning that children often share similar heights with their parents and other family members. While genetics plays a crucial role, nutrition is equally important, as a balanced diet supports overall growth and development.

Just like how some flowers grow to be similar in size and color to their parent plants, children often grow to be similar in height to their parents, but they also need proper care and nutrients to flourish.

It helps the bones, muscles and other parts of the body get adequate nourishment for growth. You will find nutritional needs of adolescents discussed later in the lesson.

Adequate nutrition is essential during the growth spurt of adolescence as it provides the necessary nutrients for developing bones, muscles, and overall body function. The chapter will explore how dietary choices significantly impact growth during this crucial life stage.

Imagine fueling a car—just as a car runs better with quality fuel, children will grow optimally when they consume nutritious foods like fruits, vegetables, and proteins.
