Short hydration lessons boost water intake in schoolchildren, study finds
NCT ID NCT07669909
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a six-week multimedia education program could improve hydration knowledge and drinking behavior in 204 first-grade children (ages 6-7) in Tunisia. Twelve classes were randomly assigned to either receive the program during PE or continue as usual. Researchers measured hydration knowledge, whether children drank water during PE, and body weight changes. The goal was to see if engaging lessons could turn knowledge into action.
What this could mean

- Multimedia hydration education programme
- What this could lead to
- If successful, this approach could help schools improve children's hydration habits during physical activity, supporting better health and concentration.
- What could go wrong
- This is a small, completed trial in two schools in Tunisia, so results may not apply to other settings. The study measured short-term changes, not long-term health outcomes.
