Finding F-0854

“Children who experienced an episode of severe pneumonia had median CO of 0.44 ppm (IQR, 0.16 to 1.23 ppm), and those with severe pneumonia with low oxygen saturation had a median CO of 0.25 ppm (IQR, 0.20 to 0.57 ppm).”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Outcome: Pneumonia
Population: children under 5 years
Setting: home, MW
Study design: longitudinal analysis inside the Cooking and Pneumonia Study, a cluster-randomised trial of cleaner-burning biomass cookstoves in rural Malawi: repeated 24-hour personal carbon monoxide (5521 measurements) and carboxyhaemoglobin (4065 measurements) in children under five against pneumonia episodes, with mixed models adjusted for time, age, sex and smokers in the household (class 3)
Effect: median 0.25
Averaging time: 24 h
Sample: 5521 measurements
Caveat: again the sicker children had the lower exposure, which the authors read as their measurements and the questionnaire data being contradictory
