NCT07592117 · NOT YET RECRUITING
Assessing the Effects of Cool Roofs on Indoor Environments and Health in Tavua, Fiji
This trial is testing whether painting rooftops with a heat-reflecting coating lowers indoor temperatures enough to measurably improve residents' health in Fiji. Researchers are tracking everything from blood pressure and sleep to mood and cognition. It is a Phase NA cluster-randomized trial — meaning whole neighborhoods are assigned to the intervention, not individuals — and it is designed to find out whether this low-tech housing fix actually works.
You may qualify if
- Permanent household resident.
You're excluded if
- Roof damage, inaccessible or instability of roof adversely affecting cool roof coating application.
- Participant unable to provide written/verbal informed consent.
