5-year effects of switching from smoky fuels to LPG on children's development
Assessing the 5-Year Effects of a 500-day Liquefied Petroleum Gas Cooking Intervention: Continued Follow up of Participants from the Household Air Pollution Intervention Network (HAPIN) trial
This project follows children whose families received clean LPG stoves during pregnancy to see how reduced household smoke affects their growth, brain development, and air pollution exposure up to age 5.

What this research studies
Your child will be followed because your household took part in the original HAPIN trial and received a free LPG stove; researchers will track growth, physical health, and thinking/behavior skills through age 5. Staff will measure each child’s personal exposure to fine particles (PM2.5) and black carbon at multiple time points and perform standard developmental tests during clinic or home visits. Although the LPG fuel support ended at age 1, the team will document ongoing exposures to compare how early-life and later exposures relate to outcomes. The follow-up work continues at HAPIN sites in Guatemala, India, Peru, and Rwanda.
Who could benefit from this research
Good fit: Children enrolled in the original HAPIN trial whose households received the LPG stove during pregnancy or infancy and who live near the study sites in Guatemala, India, Peru, or Rwanda are the ideal candidates.
Not a fit: Children who were not part of the original HAPIN trial, who never received the LPG intervention, or who are older than five are not eligible and are unlikely to receive direct benefit from this follow-up.
Why it matters
Potential benefit: If successful, the work could show that cleaner cooking in pregnancy and infancy leads to better child development and health, supporting policies to expand clean-fuel access.
How similar studies have performed: The original HAPIN trial produced large reductions in personal PM2.5 and black carbon exposure and had excellent retention, but long-term effects on child development remain unproven, so this follow-up builds on promising exposure results.
