Finding F-0855

“However, a positive and significant association was observed for CO and BMI with 1.66 increased odds of being overweight or obese (95% CI: 1.10 to 2.51), compared to being underweight or normal weight with each unit increase in log-transformed CO.”

Structure

Source: Biomass fuel
Factor: Carbon monoxide (CO)
Outcome: Obesity
Population: adult women in rural areas
Setting: personal exposure of the woman in the household
Study design: cross-sectional analysis of the baseline visit of the Household Air Pollution Intervention Network (HAPIN) trial in rural Guatemala, India, Peru and Rwanda: 24-hour personal PM2.5, black carbon and carbon monoxide of adult women against body mass index, with linear and logistic models adjusted for age and household assets (class 4)
Effect: OR 1.66 (1.10–2.51) per one unit increase in log-transformed 24-hour personal carbon monoxide
Caveat: a baseline cross-section, so the direction of the relation is not settled; the authors restate it as a 66 % increase in the odds
