Perfluoroalkyl Substances and Metabolic Syndrome: A Cross-Sectional Study Using Data from the US National Health and Nutrition Examination Survey

Epidemiological studies linking metabolic syndrome (MetS) and exposure to perfluoroalkyl substances (PFASs) are limited, and the observations gleaned thus far are inconclusive. The study was performed to explore the association of serum PFASs both singly and in a mixed manner with MetS, and meanwhile to examine whether this association was mediated by serum albumin in a US national population.
