A recent study published in The Lancet Global Health explored whether switching from biomass to liquefied petroleum gas (LPG) for cooking in low-resource settings could improve fetal growth by reducing pregnant women’s exposure to household air pollution. Conducted in India, Guatemala, Rwanda, and Peru, the Household Air Pollution Intervention Network (HAPIN) randomized control trial involved 3,200 pregnant women. Researchers supplied half the participants with LPG stoves and fuel deliveries, while the other half continued using biomass for cooking. Despite reduced air pollution exposure in the LPG group, analyses found no significant difference in fetal growth outcomes, including birth weight and head and abdominal circumference measurements, between the two groups. Additionally, exposure to air pollution was not consistently linked with fetal growth metrics. While the study confirmed LPG stoves reduced pollution exposure, it concluded this reduction was insufficient to produce measurable benefits for fetal development. This finding highlights the complex influence of air quality on prenatal health and suggests that further interventions or environmental adjustments may be necessary to improve fetal health outcomes in these settings.
