Girls are going through puberty earlier than ever and obesity is to blame
Researchers found that African American girls first show signs of breast development at eight years and 10 months, on average. Hispanic girls first show signs of breast development at nine years and four months on average, and white and Asian girls at nine years and eight months. For white girls, the researchers found that puberty is now hitting about four months earlier than in a 1997 study that also measured breast development. They also discovered that heavier girls tend to start developing breasts at a younger age.
