Summary
This study in 140 rural secondary schools in Madagascar tests which parts of a hygiene program — new latrines and handwashing stations, peer-led sensitization, or free sanitary pad vouchers — most improve adolescent girls' learning, stress, and physical health. Researchers will measure test scores, blood pressure, heart rate, stress hormones, and infection markers in about 3,080 girls aged 11–21. The goal is to untangle what works best to support girls' well-being and education.
What this could mean

- Active substance

- What this could lead to
- If successful, this could show which combination of infrastructure and education best improves girls' health, learning, and well-being in low-resource settings.
- What could go wrong
- This is a large field study with many variables; results may not apply to other regions, and health biomarker collection is an add-on to the original learning-focused trial.
