The relationship between serum PFCs and thyroid function has never been addressed in a nationally representative survey. Objectives: The study examined the association between serum PFCs and thyroid function in the general U. S. population. Design and Participants: We selected 1181 subjects (aged >20 years) from a National Health and Nutrition Examination Survey (NHANES) in 2007 through 2008 and 2009 through 2010 to determine the relationship between serum PFCs and thyroid function. Data were adjusted for confounding variables. Results: The geometric means and 95% confidence interval (CI) concentrations of perfluorooctanoate (PFOA), perfluorooctane sulfonate, perfluorononanoic acid, and perfluorohexane sulfonate (PFHxS) were 4.15 (4.02-4.29), 14.2 (13.59-14.86), 1.54 (1.48-1.59), and 2.00 (1.89-2.11) ng/mL, respectively. After weighting for sampling strategy, we determined a 1-U increase in natural log-serum PFOA increased serum total T-3 concentration by 6.628 ng/dL (95% CI = 0.545-12.712, P = .035) in women. A 1-U increase in natural log-PFHxS was associated with an increase of total T-4 by 0.26 mu g/mL (95% CI = 0.108-0.413, P = .002) and total T-3 by 4.074 ng/dL (95% CI = 2.232-5.916, P < .001) in women and a decrease of natural log-free T-4 by 0.016 (ng/dL)(95% CI = -0.029 to 0.003, P = .019) in men. Conclusion: Higher serum concentrations of PFOA and PFHxS are associated with total T-3, total T-4, and free T-4 in the U. S. general population. More studies are warranted to clarify the causal relationship between PFCs and thyroid function. |
