摘要:The information gained from national surveys is essential for monitoring performance towards health goals and targets and informing allocation of resources for health priorities. Recent evidence of the negative impact of house- hold air pollution on health suggests that it is time to upgrade national surveys to inform decision-making on improved fuels and cookstoves. More than 40% of the world's popula- tion rely on solid fuels such as wood, crop residues or dung for their cooking and heating needs. 1 Household air pollution, caused by cooking indoors with solid fuels, is the third leading risk factor for morbidity and mortality globally. In 2010, 3.5 million deaths and 4.3% of global dis- ability adjusted life years were attributable to household air pollution. 2 , 3 Pollutants from inefficient combustion of solid fuels, especially black carbon particles, also con- tribute to g lobal climate change.
