Adolescents and Young Adults

Contact the Child and Adolescent Health Program

An adolescent is defined as any person between the ages of 9–18. Adolescence is a unique developmental time in the lifespan of every individual, characterized by distinct and dramatic physical, social, emotional and intellectual changes. The physical and emotional changes that take place in adolescence are second only to the extensive changes that take place in infancy. Many lifestyle behaviors that contribute to or reduce risk for chronic disease and disability in adulthood are developed in adolescence.
