Departments of family medicine--including departments of family and community medicine, departments of family and preventive medicine, and departments of family practice-at U.S. medical schools regularly participate in teaching prevention principles to students, using a variety of formats and methods. Required clinical experiences (i.e., clerkships and preceptorships), required nonclinical courses, and electives frequently include prevention content. Collaborative interdisciplinary clerkships, interdisciplinary nonclinical courses, and courses directed by other departments also enable family medicine faculty to teach prevention principles. This article describes examples of innovative educational programs in which family medicine faculty teach prevention content to medical students. Directions for future educational efforts by family medicine faculty in the prevention area are proposed.
