Abbreviations: NA, not available; NHANES, National Health and Nutrition Examination Survey. aTo compute the geometric mean, phthalate metabolite concentrations < LOD were replaced by LOD divided by the square root of 2. bGeometric mean phthalate metabolite concentrations among 1,411 female NHANES 2001–2002 participants age ≥ 6 years (CDC 2015). c∑DEHP is expressed as micromoles/L. dMECPP was not included in NHANES 2001–2002; data are from NHANES 2003–2004 (n = 1,355).
