Greater efforts are needed to bring affordable, clean stoves and adaptive behavioral strategies to the millions of households worldwide that continue to burn solid cooking fuels using inefficient stoves. Two of the leading causes of infant mortality, preterm birth and pneumonia, are associated with high exposures to household air pollution during pregnancy and early infancy. The proposed study will assess the feasibility and acceptability of an introduced liquid petroleum gas stove, complemented by two alternative approaches to delivering tailored behavioral change interventions, among pregnant women and their neonates.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Phase 1 | Experimental | In Phase I, 25 pregnant women will receive a low-cost gas stove and will be taught by peer educators in group classes how to safely use gas stoves and how to reduce exposure to air pollution. |
|
| Phase 2 | Experimental | In Phase 2, the investigators will assess a more resource-intensive behavioral intervention approach with a different group of 25 women who will follow the same study procedures described in Phase I. |

| Resource-intensive behavioral intervention approach | Behavioral | Women will participate in four classes on how to safely use gas stoves and methods to reduce exposure to air pollution. Additionally, peer educators will visit each home after group classes to help the woman, and key decision-makers in her family, identify top priority strategies to reduce air pollution. Using a checklist, peer educators will observe whether household members are adhering to tailored strategies at subsequent home visits, and provide ongoing support to women and their families. |
