Adolescent is a time of psychosocial, cognitive, and physical development as young people make the transition from childhood to adulthood. The Women’s Health and Education Center (WHEC) believes healthcare professionals have an obligation to provide the best possible care to respond to the needs of their adolescent patients. The delivery of preventive services to adolescents differs from the delivery of preventive services to adults. Furthermore, not all adolescents of the same age are at the same stage of development, thus necessitating further examination of adolescent’s physical, sexual, psychosocial, and cognitive development. Understanding the milestones and developmental stages of adolescence is beneficial to obstetricians and gynecologists treating adolescents. Comprehensive services may be delivered to adolescents in a variety of sites, including schools, physician offices, and community-based and other health care facilities. Legal barriers that restrict the freedom of healthcare practitioners to provide these services are also discussed.
