Summary

This study looks at girls aged 6 to 8 who are showing early breast development. Researchers want to understand if chemicals in the environment, called endocrine disruptors, play a role. They will measure these chemicals in hair and blood, and also check body fat and growth. The goal is to see if simple environmental health measures can help slow or change this early development.
