U.S. girls keep hitting puberty earlier

Researchers found African American girls started getting breasts just before they turned nine, on average. The findings "confirm an ongoing downward trend in pubertal timing among U.S. girls," said Dr. Anders Juul. "It's been worrying for the U.S. as well as the rest of the world," Juul said. At each visit, staff assessed breast development using Tanner stages, which measure how far along a young person is in puberty.
