The first large-scale and nationally representative study of its kind confirms the existence of a link between phthalates and lower-than-normal thyroid hormone levels.
More specifically, the group of researchers compared urine metabolites and serum thyroid measures from over 1,600 adults and adolescents and found an inverse relationship between markers of exposure and thyroid levels – thus, as urinary metabolite concentrations increased (showing presence of phthalates), so the serum levels of certain thyroid hormones decreased and levels of TSH (a marker of low thyroid function) increased.
The correlation was strongest between thyroid disruption and DEHP, a form of phthalates used as plasticisers. In addition, the study found a similar correlation between Bisphenol-A levels and thyroid disfunction.
The study was conducted by researchers at the University of Michigan and the complete results can be found here.
