Summary

This study follows about 566 children who were part of an earlier infant study to see how things like growth, hormones, and feeding in early life relate to when puberty begins. Teens and their parents will fill out questionnaires, measure height and weight, and collect urine samples at home over a year. The goal is to understand why puberty is starting earlier in recent decades.
