Long-term effects of clean LPG cooking on children's health
Long-term Effects of a household Air Pollution intervention: Follow-up of a randomized controlled trial
This follow-up tracks children whose homes were given clean LPG stoves to see how breathing cleaner air affects lung growth, heart risk factors, and development up to age eight.

What this research studies
If my child is part of this follow-up in Puno, Peru, researchers will return once a year to measure lung function, cardiovascular risk markers, and developmental milestones through age eight. They will measure kitchen and personal PM2.5 exposure yearly and continuously monitor biomass stove use with temperature loggers. The project follows children from the original HAPIN intervention who received 18 months of LPG stoves, fuel, and behavior messaging and compares them with children from control households. Data will be analyzed to link measured pollution and actual stove use to health and development outcomes over time.
Who could benefit from this research
Good fit: Ideal candidates are children enrolled in the original HAPIN trial in Puno, Peru who were exposed to household biomass smoke and can be followed annually through age eight.
Not a fit: People who were never exposed to household air pollution, adults, or families not living in the Puno HAPIN cohort are unlikely to benefit directly from participation.
Why it matters
Potential benefit: If successful, the project could show that replacing biomass stoves with LPG during early childhood reduces respiratory problems, improves growth and development, and lowers future cardiovascular risk.
How similar studies have performed: Previous short-term clean-cooking trials, including the 18-month HAPIN intervention, showed mixed or delayed health signals, making this long-term follow-up relatively novel and necessary.
