Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only This study
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

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

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
peer leadership/sensitization program, sanitary pad vouchers, and school latrine/handwashing basin construction
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.

Study facts

What this study's own registry entry says, in plain language.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 3,080 people

The number the study aims to enrol. It can still change while the study runs.

Started

Oct 2024

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

11 to 21 years

Sex

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Girl identified in the Kilonga 2 evaluation sample (randomly selected during the December 2024-January 2025 baseline from class registers across the 140 participating schools); participants were 11-20 years old at baseline enrollment and are approximately 12-21 years old at the time of endline/health-outcomes data collection (May-August 2026) * Full evaluation sample (n\~3,080; \~22 girls/school): all girls in the Kilonga 2 sample across the 140 schools are eligible for the cognitive, self-reported psychosocial, and non-biospecimen health outcomes, collected at the social-science endline. * Biomarker subsample (n\~1,360; \~17 girls/school): girls attending one of the 80 schools selected for the health biomarker subsample (logistically accessible for biospecimen collection and cold-chain maintenance) are additionally eligible for salivary cortisol and blood-based C-reactive protein outcomes. * Informed consent obtained from parent/legal guardian, and assent obtained from the participant herself Exclusion Criteria: * Adolescents not meeting the inclusion criteria above * Adolescents (or their parent/legal guardian) who refuse to participate or who withdraw consent/assent at any time * Adolescents for whom sample collection is judged impossible or contraindicated at the time of collection (e.g., health status precluding collection)
