Finding F-0880

“The mean of expired air carbon monoxide and estimated carboxyhemoglobin levels of liquid petroleum gas-only users (2.84 ± 2.85 ppm; 1.08 ± 0.46%) were significantly lower than those of firewood-only users (5.27 ± 4.64 ppm; 1.47 ± 0.74%).”

Structure

Source: Liquefied petroleum gas (LPG)
Factor: Carbon monoxide (CO)
Outcome: Exhaled carbon monoxide
Population: reproductive-aged women
Setting: home, LK
Study design: descriptive cross-sectional study among 403 reproductive-aged women (15 to 49 years) in the Central Province of Sri Lanka: cooking fuel and respiratory symptoms from an interviewer-administered questionnaire, exposure assessed with a breath carbon-monoxide monitor and carboxyhaemoglobin estimated from it, with logistic regression adjusted for confounders (class 4)
Effect: mean 1.08
Sample: 403 participants
Caveat: a breath measurement in the woman, not a room concentration; the carboxyhaemoglobin is estimated from the breath reading, not measured in blood
