Adolescence is a period of transition from childhood to adulthood with many physical, physiological and psychological changes.

Surbhi Rathi, Mukesh Agrawal

WHO defines Adolescence from 10-19 years of age, which may be arbitrarily divided into 3 phases—early adolescence (10-13 years), mid adolescence (14-16 years) and late adolescence (17-19 years). While Early adolescence is a period of rapid physical and sexual growth, mid­adolescence is characterized by relative slowing of growth spurt but intense emotional changes to develop self­identity. Late adolescence marks the completion of physical growth and psychosocial stabilization.
