ABSTRACT
26
Traditional cooking using biomass is associated with ill health, local environmental degradation, and
27
regional climate change. Clean stoves (liquefied petroleum gas (LPG), biogas, electric) are heralded as a
28
solution, but few studies have demonstrated their environmental health benefits in field settings. We
29
analyzed the impact of mainly biogas (as well as electric and LPG) stove use on social, environmental,
30
and health outcomes in two districts in Odisha, India, where the Indian government has promoted
31
household biogas. We established a cross-sectional observational cohort of 105 households that use either
32
traditional mud stoves or improved cookstoves (ICS). Our multidisciplinary team conducted surveys,
33
environmental air sampling, fuel weighing and health measurements. We examined associations between
34
traditional or improved stove use and primary outcomes, stratifying households by proximity to major
35
industrial plants.

ICS use was associated with 91% reduced use of firewood (p80) and normal FEV/FVC (>72)
204
in ICS owners were calculated. FEV1 percent predicted is calculated as the actual FEV1 divided by the
205
predicted FEV. Only one cook reported use of tobacco, and was dropped from the analysis. All analyses
206
were evaluated separately for all cooks, cooks
