Lung function is adversely affected by exposure to household air pollution (HAP). Studies investigating the impact of prenatal and postnatal HAP on early childhood lung development are limited, especially from Sub-Saharan Africa. We used oscillometry investigate children born Nigerian women who participated in a randomized controlled cookstove intervention trial. performed oscillometric measurements (R: airway resistance; X: reactance; Fres: resonant frequency; AX: reactance area) 223 starting at age 2 years (ethanol stove, n = 113; firewood/kerosene, 110). Personal monitoring assessed mothers' particulate matter less than 2.5 μm aerodynamic diameter (PM2.5). Postnatal was measured determining PM2.5 levels. employed linear regression analysis examine association exposures with children's function. Models were adjusted for age, gender, weight, height, group (intervention or control), birthweight gestational age. Mean 2.9 (standard deviation 0.3); 120 boys (53.8%) 103 girls (46.2%). Higher significantly associated higher 5 Hz (X5 Hz; p 0.04) models. There no significant associations between levels other parameters analysis. This first study use explore relationship as young years. The findings provide some evidence that increased may result poorer children, although larger studies needed confirm observed results. indicates low-cost effective method determine childhood.
