7.2.2 Change in Body Shape

Description

Quick Overview

This section discusses the changes in body shape during adolescence and puberty, highlighting physical differences between boys and girls.

Standard

During puberty, adolescents experience significant changes in body shape, including broader shoulders in boys and wider hips in girls. The section outlines the influential role of hormones in these changes, the development of secondary sexual characteristics, and the psychological aspects of growing up.

Detailed

In this section, we explore how body shape changes during adolescence, a phase that begins around ages 11 to 19. For boys, significant changes include broader shoulders and muscle growth, while girls experience widening of the hips. This transformation is driven primarily by hormones—testosterone in boys and estrogen in girls—resulting in secondary sexual characteristics such as facial hair in boys and breast development in girls. The section also emphasizes the importance of nutrition and health during this critical growth period, as well as addressing the emotional and psychological adjustments that come with these physical changes.
