Summary

This study is an observatory that will track up to 3360 children in private healthcare who show signs of early or advanced puberty. Researchers will collect data like height, weight, and pubertal stage to better understand trends and possible causes, such as environmental factors. The goal is to gather reliable information to supplement current knowledge, not to test a treatment.

What this could lead to: If successful, this could provide valuable data to help understand why puberty is starting earlier and guide future research or public health strategies.
What could go wrong: This is an observational study, not a treatment trial. It may not identify clear causes, and data collection might be incomplete or not representative of the general population.
