Observational Study for Children with Idiopathic Short Stature

This study is looking at children with Idiopathic Short Stature (ISS), which means they are shorter than average for no known medical reason. Researchers want to understand how these children grow over time. They will be collecting information on your child's growth, including their height and how fast they are growing. The study aims to track these changes for up to 15 years. Children between 2 and 16 years old (up to 14 for girls, up to 16 for boys) who have a height significantly below average may be able to join. The study is currently unclear on its recruitment status.

Study design

What's involved
Your child's height and growth will be measured every 6 months for up to 15 years.
Compensation
