Summary

This study tested whether giving pregnant women in India, Guatemala, Peru, and Rwanda cleaner-burning LPG stoves (instead of smoky biomass fuels) leads to healthier babies. About 3,200 households took part, with half receiving the stoves and fuel. Researchers tracked birth weight, pneumonia, and growth in the first year, plus blood pressure in older women. The goal was to see if reducing indoor smoke improves key health outcomes.
