Association between perfluoroalkyl and polyfluoroalkyl substances exposure and hypercholesterolemia among US adults: A cross-sectional study
Science
25 Aug 2025 | Ecotoxicol Environ Saf.
Analysis of NHANES 2015–2018 data (n = 2,292) showed that higher serum levels of PFHxS, PFOA, and PFOS were significantly associated with increased prevalence of hypercholesterolemia, with PFHxS as the strongest contributor in mixture models, while combined PFAS exposure consistently elevated risk across multiple statistical approaches.
