Johns Hopkins pulmonologist William Checkley discusses “Effects of Cooking with Liquefied Petroleum Gas or Biomass on Stunting in Infants” ¬ — his recent publication in The New England Journal of Medicine. In this study, the researchers conducted a randomized trial of a liquefied petroleum gas stove, continuous free fuel distribution and longitudinal behavioral messaging as a strategy to mitigate household air pollution and improve health. This large trial was conducted in 3,200 households in multiple countries with women who were pregnant, half of whom were randomly assigned to cook using unvented liquefied petroleum stoves. The other half were asked to continue cooking with biomass stoves.
