Household Air Pollution (HAP) Study

The Household Air Pollution (HAP) project is a randomized controlled trail (RCT) evaluating the impact of HAP on pregnancy outcomes. HAP is responsible for over 4million premature deaths in developing countries annually, with 95,000 annual deaths in Nigeria attributed to HAP according to WHO. The goal of the study is to investigate the impact of exposure to HAP on risk of ALRI including pneumonia, atopy and asthma in children under five. Cleancook ethanol cookstove are being used for this study. The goal is that the research findings will improve our understanding of the health impact of exposure to HAP and highlight the effectiveness of an ethanol stove in improving indoor air quality. We are hopeful that final results from the study will also influence policy on appropriate cooking fuels, home construction standards and advocacy for rural electrification.
