A thorough understanding of adolescence in society depends on information from various perspectives, including psychology, biology, history, sociology, education, and anthropology.Within all of these perspectives, adolescence is viewed as a transitional period between childhood and adulthood, whose cultural purpose is the preparation of children for adult roles.In studying adolescent development, adolescence can be defined biologically, as the physical transition marked by the onset of puberty and the termination of physical growth; cognitively, as changes in the ability to think abstractly and multi-dimensionally; or socially, as a period of preparation for adult roles.

This non-uniform growth is one reason why an adolescent body may seem out of proportion.

During puberty, bones become harder and more brittle.

In addition to changes in height, adolescents also experience a significant increase in weight (Marshall, 1978).

The weight gained during adolescence constitutes nearly half of one's adult body weight.

Consequently, girls that reach sexual maturation early are more likely than their peers to develop eating disorders (such as anorexia nervosa).

Nearly half of all American high school girls' diets are to lose weight.

Puberty occurs through a long process and begins with a surge in hormone production, which in turn causes a number of physical changes.

It is the stage of life characterized by the appearance and development of secondary sex characteristics (for example, a deeper voice and larger adam's apple in boys, and development of breasts and more curved and prominent hips in girls) and a strong shift in hormonal balance towards an adult state.

Puberty is a period of several years in which rapid physical growth and psychological changes occur, culminating in sexual maturity.

The average age of onset of puberty is at 11 for girls and 12 for boys.

Physical growth (particularly in males), and cognitive development can extend into the early twenties.
