Finding F-0841

“However, 24 weeks, the period of intensive HAP education, provided between late 2017 and early 2018, was sufficient to decrease study subjects’ mean CO levels (measured by COoximetry) by 69% (15.9% to 4.9%) and the controls by 66% (17.8% to 6.0%); the study children by 79% (13.1% to 2.8%) and the control children by 69% (14.0% to 4.4%).”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Population: children of the intervention mothers
Setting: home, SD (24 weeks of education, late 2017 to early 2018)
Study design: prospective cohort in Port Sudan, Sudan, 2016 to 2019: women who cooked indoors were offered a well-ventilated outdoor cooking shelter (rakoobah) and 24 weeks of household air pollution education, against a control group; carboxyhaemoglobin was measured by CO-oximetry in the women and in their children each year (class 3)
Effect: difference 79
Caveat: the drop is almost the same in the control groups, so it cannot be read as an effect of the ventilated cooking shelter; the authors credit the education, which both groups received
