In 30 seconds
This study protocol outlines a cluster-randomised controlled trial in rural Pakistan to assess the effectiveness of a Resilience and Heat Adaptation Bundle (ReHAB) aimed at reducing heat-related morbidity and mortality. The trial will involve 22 clusters and evaluate the impact of combined community education and structural interventions on indoor thermal conditions and health outcomes.
Key findings
- The trial will include 22 clusters allocated in a 1:1 ratio to intervention and control arms.
- ReHAB integrates community education with structural improvements like roof treatments and enhanced shading.
- Health and behavioural data will be collected through household surveys and wearable devices.
Why it matters
As climate change intensifies, understanding effective heat adaptation strategies in vulnerable rural populations is crucial for public health. This trial could inform future interventions to mitigate heat-related health risks in similar settings.
