For More Children, Puberty Signs Start at 8

Sumathi Reddy:

When Frank Biro walks into a class of second- or third-graders these days, there are almost always a couple of girls who look different than the rest.

“There will be quite a few girls that look like they’re going into early puberty,” says Dr. Biro, a professor of pediatrics at Cincinnati Children’s Hospital Medical Center who gives talks about puberty at schools occasionally.

Dr. Biro researches a phenomenon that has increasingly captured the attention of researchers: Puberty appears to be starting earlier in healthy girls, and possibly even boys. At Kaiser Permanente in Northern California, clinicians begin assessing girls for changes related to puberty at age 6.
