Which age group is most concerned with body image?

Adolescence is the age group most concerned with body image due to the significant physical, emotional, and social changes that occur during this developmental stage. This period often involves heightened self-consciousness and a desire for peer acceptance, which can lead to increased scrutiny of one's own appearance and body shape. Adolescents are influenced by societal standards of beauty, media portrayals, and peer comparisons, all of which can intensify their concerns regarding their bodies.

While concerns about body image can manifest in other age groups, they are particularly pronounced during adolescence. Infants are not aware of body image; children may begin to develop some awareness but typically show less concern than adolescents. In adulthood, while body image still matters, it is often more stable and informed by different factors, such as health rather than pure appearance. Therefore, the concerns with body image peak during adolescence, making it the correct choice for this question.
