Adolescent medicine
（重定向自Ephebiatrics）
Adolescent medicine or hebiatrics is a medical subspecialty that focuses on care of patients who are in the adolescent period of development, generally ranging from the last years of elementary school until graduation from high school (some doctors in this subspecialty treat young adults attending college at area clinics, in the subfield of college health). Patients have generally entered puberty, which typically begins between the ages of 9 and 11 for girls, and between 11 and 13 for boys.
