Using data from the National Health and Nutrition Examination Survey, regression models were fitted to assess the relationship between the levels of bisphenol A and selected parabens and pregnancy status among females 20–44 years old with adjustments made for factors that may affect the levels of these chemicals. Pregnancy did not affect the levels of bisphenol A, ethyl paraben, methyl paraben, and propyl paraben, but the pregnancy was found to be associated with increased levels of butyl paraben. Also, the levels of bisphenol A and butyl, ethyl, and methyl parabens increased as pregnancy progressed from the first trimester to the third trimester. The increasing levels of bisphenol A and parabens during pregnancy are of concern and need further clinical explanation.
