What this research studies

If your child was part of the original HAPIN trial in Puno, Peru, researchers will continue to follow them through age eight to track health outcomes. Each year they will measure air pollution levels (PM2.5) in the kitchen and on the child, and they will continuously monitor stove use with temperature loggers. The team will collect lung function tests, cardiovascular risk markers, growth measures like BMI, and neurodevelopmental assessments. Children from homes that received LPG stoves and fuel will be compared with control households to see long-term differences.

Who could benefit from this research

Good fit: Ideal candidates are children who were enrolled in the original HAPIN randomized trial in Puno, Peru, especially those followed since infancy.

Not a fit: Children who were not part of the original trial or who live outside the Puno region are unlikely to be eligible or directly benefit from this follow-up.

Why it matters

Potential benefit: If successful, this follow-up could show that providing LPG stoves and fuel leads to lasting improvements in children’s lung health, cardiovascular risk, and neurodevelopment.

How similar studies have performed: Previous short-term cleaner-cooking trials showed mixed or delayed benefits, so this long-term follow-up addresses outcomes earlier studies may have missed.
