Endocrine disruptive chemicals (EDCs) are considered as the potential attributes for the increasing trend in obesity and metabolic syndrome (MS) through disruption of sex hormones, particularly in women. We evaluated the association of understudied EDC compounds with total testosterone (TT), sex hormone-binding globulin (SHBG), obesity, and MS. A population-based cross-sectional study was conducted using the National Health and Nutrition Examination Survey datasets collected during the years 2013–2016. Women of age ≥15 years with urinary measurements of nonpersistent EDCs, including bisphenol, triclosan, triclocarban, dichlorophenol, and paraben compounds were included in this study. Data were analyzed using the modified Poisson models to estimate the adjusted relative risk (RR) and 95% confidence interval (CI). The associations were also validated by considering TT and SHBG concentrations as the outcomes. The study included 1974 women with 11% high TT, 10.5% low SHBG, 40% obesity, and 46.2% MS. A medium to high exposure to bisphenol-A (RR = 1.64; 95% CI: 1.14, 2.35, p = 0.009), bisphenol-F (RR = 1.83; 95% CI: 1.35, 2.49, p < 0.001), bisphenol-S (RR = 1.83; 95% CI: 1.35, 2.49, p = 0.041) and 2, 4- dichlorophenol (RR = 1.61; 95% CI: 1.06, 2.45, p = 0.026) were associated with low SHBG but not with high TT. In addition, high exposure to triclosan was also inversely associated with SHBG concentrations (regression coefficient = −0.09; 95% CI: −0.15, −0.02, p = 0.013). However, these EDCs were found to be associated with SHBG, obesity, and MS according to menopausal status. High exposure to certain nonpersistent EDCs was associated with low SHBG, obesity, and MS according to menopausal status.
