Associations of PFAS and pesticides with lung function changes from adolescence to young adulthood in the ESPINA study.

ABSTRACT: Per- and polyfluoroalkyl substances (PFAS) and pesticides are widespread environmental contaminants linked to adverse health outcomes; yet, their impact on lung function-individually and as mixtures-remains poorly understood. This study analyzed data from 381 adolescents in a longitudinal cohort in Ecuador, measuring serum levels of three PFAS (perfluorooctanoic acid [PFOA], perfluorooctanesulfonic acid [PFOS], and perfluorononanoic acid [PFNA]) and urinary levels of three pesticides (glyphosate, 2,4-dichlorophenoxyacetic acid [2,4-D], and ethylene thiourea [ETU]). Spirometric lung function was assessed in 2016 and 2022. We evaluated associations between individual chemical levels and lung measures in log-log models estimated via ordinary least squares regression. We used quantile g-comput
