Emerging evidence indicates that environmental exposure to per- and polyfluoroalkyl substances (PFASs) may influence lipid metabolism, though studies on adolescents remain scarce. This study aimed to investigate the association between PFAS mixture exposure and lipid profiles in Korean adolescents. Using data from the Korean National Environmental Health Survey (2018&ndash:2020), we analyzed 824 adolescents aged 12&ndash:17 years. Serum concentrations of PFAS, including perfluorooctanoic acid (PFOA), perfluorooctane sulfonic acid (PFOS), perfluorononanoic acid (PFNA), perfluorohexane sulfonic acid (PFHxS), and perfluorodecanoic acid (PFDeA), and lipid profiles were assessed. In multivariate regression models, PFDeA and PFNA were positively associated with elevated total cholesterol and low-density lipoprotein cholesterol levels, and PFDeA was associated with hypercholesterolemia risk in boys. In girls, PFDeA was associated with higher high-density lipoprotein cholesterol and lower triglycerides, though no significant association with hypercholesterolemia risk was observed. Bayesian kernel machine regression demonstrated positive associations between PFAS mixture exposure and hypercholesterolemia risk in boys but not in girls. The quantile g-computation model also demonstrated an odds ratio (OR) of 1.47 (95% CI: 0.99&ndash:2.19, p = 0.057) for PFAS mixture exposure in boys, suggesting borderline statistical significance. These findings suggest that PFAS exposure may disrupt lipid metabolism, elevating hypercholesterolemia risk in adolescents, particularly boys.
