Clean Cooking Fuels to Improve Health during Pregnancy

This editorial discusses the findings of the Household Air Pollution Intervention Network (HAPIN) trial, which investigated the health impacts of replacing traditional biomass stoves with liquefied petroleum gas (LPG) stoves in pregnant women across Guatemala, India, Peru, and Rwanda. Despite significant reductions in exposure to harmful pollutants (66–83% lower fine particulate matter, black carbon, and carbon monoxide), the trial found no statistically significant difference in birth weight, preterm birth, or stillbirth between intervention and control groups. The authors explore potential reasons for these null results, including late intervention timing and nonlinear exposure response relationships. They emphasize the broader need for multi sectoral air quality improvements beyond household interventions. The article underscores the complexity of addressing household air pollution’s health effects while advocating for continued efforts toward clean energy transitions in low resource settings.
