Abstract Domestic cooking with biomass fuels exposes women and children to pollutants that impair health. The objective of the study was to investigate the extent of household air pollution from biomass fuels and the effectiveness of stove intervention to improve indoor air quality, exposure-related health problems, and lung function. We conducted a community-based pilot study in three rural communities in southwest Nigeria. Indoor levels of particulate matter (PM2.5) and carbon monoxide (CO) were measured, and exposure-related health complaints were assessed in 59 households that used firewood exclusively for O.

cooking. Fifty-nine mother–child pairs from these households were evaluated pre-intervention and 1 year after distribution and monitored use of low-emission stoves. Mean age (± SD; years) of mothers and children were 43.0±11.7 and 13.0±2.5, respectively. Median indoor PM2.5 level was 1414.4 μg/m3 [interquartile range (IQR) 831.2–3437.0] preintervention and was significantly reduced to 130.3 μg/m3 (IQR 49.6–277.1; p70 %), mild (FEV1 ≥80 % predicted, FEV1/FVC
