Abstract
Context: Perfluorooctanoic acid (PFOA) and perfluorooctane sulfate (PFOS) are used in a variety of products worldwide. However, the relationship among serum PFOA, PFOS concentration, bone mineral density (BMD), and the risk of fractures has never been addressed. Objectives: The study examined the association among serum PFOA, PFOS concentration, and lumbar spine and total hip BMD in the general US population. Design and Participants: We analyzed data on 2339 adults (aged ?20 y) from the National Health and Nutrition Examination Survey conducted in 2005-2006 and 2007-2008 to determine the relationship among serum PFOA, PFOS concentration, and total lumbar spine and total hip BMD measured by dual-energy x-ray absorptiometry and history of fractures cross-sectionally. Results: After weighting for sampling strategy, a 1-U increase in the natural log-transformed serum PFOS level was associated with a decrease in total lumbar spine BMD by 0.022 g/cm2 (95% confidence interval -0.038, -0.007; P = .006) in women not in menopause. There was no association among PFOA, PFOS concentration, and self-reported fracture in adults. Conclusion: Serum PFOS concentration is associated with decreased total lumbar spine BMD in women not in menopause. However, the potential biological significance of this effect is marginal and subclinical in the general US population. Further studies are warranted to clarify the causal relationship between perfluorinated chemical exposure and BMD. ? 2014 by the Endocrine Society.
