NCT ID NCT06132763
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This pilot study tested a school-based program to encourage kids to drink more water. The program included student ambassadors, a kick-off event, and a student-led marketing campaign. Researchers looked at whether the program was feasible and if it could improve hydration, reduce cavities, and manage weight in elementary students.
