Impact of residential solid fuel usage and fuel conversion on children's lung function.

ABSTRACT: Solid fuel combustion exposure is a leading global health risk factor, yet evidence on its effects, especially on vulnerable children, is sparse. This large-scale, multi-center prospective study aimed to address this gap by involving 9997 schoolchildren across China between 2013 and 2015. Here we show that lung function levels exhibited a marginally significant decline among children exposed to solid fuel usage. Specifically, FVC and FEV1 decreased by 21.2 mL (95% CI: -15.7, 58.1) and 24.1 mL (-8.4, 56.6), respectively. Additionally, PEF, FEF₂₅ and FEF₇₅ decreased by 25.7 mL/s (-46.5, 98.0), 32.7 mL/s (-42.7, 108.2), and 35.4 mL/s (-5.9, 76.7), respectively. Persistent exposure to solid fuel usage in children led to greater lung damage. Children with allergy history were more susceptible to solid fuel exposure. Our study highlights the adverse impact of solid fuel usage on children and the need to promote clean fuel usage for this vulnerable population.
