Indoor Air Pollution Background
Sources Emissions Concentrations Exposure Dose Health Effects
• Indoor Air Pollution (IAP) is the fourth leading cause of death of children under the age of 5 in developing countries

Improved Stove Initiative
• Started in Fall of 2007
• Three Phase Study– Phase I: Preliminary Evaluation– Phase II: Monitoring and Evaluation of IAP
Emissions– Phase III: Evaluation of Entire Initiaitve

Phase II
• Selected 25 Intervention Households (Sebastian Africano)– Measured IAP Emissions (UC Berkeley)– Installed New Stoves in Intervention
Househoulds (AHDESA/Josue from SHH)– Re-Measured IAP Emissions

Phase III
53 surveys on:
1. Self-rated health of the women
2. Uptake of improved stoves
3. Sustainability of improved stoves
![Page 27: Indoor Air Pollution: A Life Threatening Problem in Siete de Abril Presented by: Christine Exley and Katie MacEwen.](https://reader036.fdocuments.us/reader036/viewer/2022062717/56649e525503460f94b47b16/html5/thumbnails/27.jpg)
1.Self Rated Health
• No valid results between overall health results and health comparisons of intervention and control group
• In which way, for better or worse, has the improved stove changed your life, if there has been any change at all?
19/26 (73.08%) cited smoke

1. Self Rated Health with respect to Smoke
• Smoke reduction influence your health?
64.17% - health improved
• Smoke reduction influenced your kids health?
• 75% – health improved

3. Sustainability
• More money needed in order to install any more stoves

Possible Solution to Uptake and Sustainability: Microfinance
