Early Puberty in Girls—What Do We Know in 2022?I remember 1997. Early puberty was THE topic of discussion among pediatric and adolescent gynecologists, adolescent medicine physicians, and pediatric endocrinologists. That year, Marcia Herman-Giddens published the landmark study entitled “Secondary sexual characteristics and menses in young girls seen in office practice: a study from the Pediatric Research in Office Settings network.” The study included the findings that at age 8, 48.3% of African American girls and 14.7% of white girls had at least 1 sign of pubertal development, earlier than was suggested in standard pediatric textbooks.
Using the Menstrual Cycle as a Vital Sign: What We Still Want to Know about Adolescent Menstrual CyclesI remember the place and the conversation. Dr. Larry Nelson and I were attending an interdisciplinary women's health education retreat in Chantilly, Virginia, in 2000 and chatted over lunch.1 Dr. Nelson was with the U.S. Public Health Service, working at the National Institute for Child Health and Disease, division of intramural research, and is known for his important work on defining and addressing primary ovarian insufficiency (POI).2 Our lunch conversation was wide ranging, but the conversation struck a chord when we started talking about the menstrual cycle.
