The researchers reevaluated field data collected in the late 1970s that included about 200 children, ages 3 to 9 years, in Belize, Kenya, Nepal, and American Samoa. The communities in Kenya and Nepal used indoor open-fire cooking with wood, straw, or dung; those in American Samoa used kerosene stoves; and those in Belize used either wood or kerosene or both. The team looked at data from several cognitive tests and activities they had carried out with the children.
