Household use of fuelwood represents a socio-ecological condition with important health effects mainly in rural areas from developing countries. One approach to tackle this problem has been the introduction of efficient wood-burning chimney stoves. The aim of this study was to assess the impact of the introduction of Patsari stoves on the respiratory health of young children in highlands Michoacán, Mexico. A total of 668 households in six rural communities in a fuelwood using region were selected and randomized to receive an improved stove (Patsari) or rely entirely on the traditional wood fire until the end of the follow-up including 10 monthly visits.
Adherence to the intervention was variable over the follow-up time. The actual use of the Patsari stove as reported by the mother showed a protective effect mainly on the upper and lower respiratory infection duration (IRR URI 0.79, 95% CI 0.70-0.89, and LRI 0.41, 95% CI 0.21-0.80) compared to households that used only an open fire. Fewer days of child’s ill health represents saved time for the woman and avoided disease treatment costs for the family, as well as a decrease in public health costs due to a reduction in the frequency of patient visits.
