NBSP – a partnership between the International Clinical Epidemiology Network (INCLEN), Columbia University, UC Berkeley, and Sri Ramachandra Institute for Higher Education and Research (SRIHER) – evaluated the feasibility of distributing clean cookstoves through the rural antenatal care system, which targets arguably the most vulnerable population — poor, pregnant, rural women. The study distributed 200 blower stoves to pregnant women at INCLEN’s SOMAARTH field site and tracked usage of the stoves continuously for > 15 months using our Stove Use Monitoring System (SUMS) and measured pollutant concentrations and exposures before and after introduction of the stove. Funding for this project came from the United States Centers for Disease Control and Prevention, the World Lung Foundation, and the World Bank.
