Description
Sheela S Sinharoy and a large trial team ask whether cleaner cooking changes blood hemoglobin in pregnant women, using the HAPIN randomized trial across Guatemala, Peru, India, and Rwanda. Homes in the trial got liquefied petroleum gas stoves and fuel, or kept cooking with wood and other biomass. The analysis covered 3178 women, with hemoglobin and 24-hour personal pollution measures taken three times across pregnancy.
Women in the gas group ended with hemoglobin higher by 0.074 grams per deciliter than controls, a small but statistically supported gain. Looking at exposure itself, each added part per million of carbon monoxide tracked with hemoglobin higher by 0.015 grams per deciliter in the reported models. Fine particles and black carbon showed no such link. The authors stop short of a mechanism and call for work on how smoke exposure moves blood values during pregnancy.
