Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Phase 1
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.
Low-cost gas stove
Women will be provided with a 3-burner liquid propane gas stove and one year's supply of gas
Peer education classes
Women will participate in four classes on how to safely use gas stoves and methods to reduce exposure to air pollution
Phase 2
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.
Low-cost gas stove
Women will be provided with a 3-burner liquid propane gas stove and one year's supply of gas
Resource-intensive behavioral intervention approach
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.
