Bisphenol A and phthalates are widely detected in human urine, blood, breast milk, and amniotic fluid. Both bisphenol A and phthalates have been suggested as playing a role in obesity epidemics. Exposure to these chemicals during fetal development, and its consequences should be concerning because they can cross the placenta. Thus, this study aimed to assess the association between prenatal exposure to bisphenol A and phthalates, and cord blood metabolic-related biomarkers. Maternal serum was used during the first trimester, to determine prenatal exposure to bisphenol A and phthalates. Levels of metabolic-related biomarkers in the cord blood were also determined. Linear regression models were applied to the 365 participants with both, exposure and biomarker assessments, adjusted for maternal age, pre-pregnancy body mass index, parity, education, and sex of the child. The level of bisphenol A was negatively associated with the leptin level (β = −0.06, 95% confidence interval [CI]: −0.11, −0.01), but was positively associated with the high-molecular-weight adiponectin level, with marginal significance (β = 0.03, 95%CI: 0.00, 0.06). The mono-isobutyl phthalate (MiBP), mono-n-butyl phthalate (MnBP), mono-(2-ethylhexyl) phthalate (MEHP), and summation of MEHP and MECPP to represent DEHP exposure (∑DEHPm) levels were inversely associated with the leptin levels (β=−0.14, 95%CI: −0.27, −0.01; β = −0.12, 95%CI: −0.24, 0.00 with marginal significance; β=0.08, 95%CI: −0.14, −0.03; and β = −0.09, 95%CI: −0.16, −0.03, respectively). The present study provided some evidence that prenatal exposure to bisphenol A and certain phthalates may modify fetal adiponectin and leptin levels.

产前双酚A和邻苯二甲酸酯暴露与胎儿代谢相关生物标记之间的关联:北海道环境与儿童健康研究

在人的尿液,血液,母乳和羊水中广泛检测到双酚A和邻苯二甲酸酯。已建议双酚A和邻苯二甲酸酯在肥胖病流行中发挥作用。在胎儿发育过程中接触这些化学物质及其后果应引起关注,因为它们可以穿过胎盘。因此,本研究旨在评估产前双酚A和邻苯二甲酸酯暴露与脐带血代谢相关生物标志物之间的关联。在孕早期使用母体血清来确定产前双酚A和邻苯二甲酸酯的暴露。还确定了脐带血中与代谢相关的生物标志物的水平。线性回归模型应用于365名参与者,并进行了暴露和生物标志物评估,并根据孕产妇年龄,孕前体重指数,均等,受教育程度,和孩子的性别。双酚A的水平与瘦素水平呈负相关(β= -0.06,95%置信区间[CI]:-0.11,-0.01),但与高分子量脂联素水平呈正相关,具有边际意义(β= 0.03,95%CI:0.00,0.06)。邻苯二甲酸单异丁酯(MiBP),邻苯二甲酸单正丁酯(MnBP),邻苯二甲酸单-(2-乙基己基)酯(MEHP)以及表示DEHP暴露(∑DEHPm)的MEHP和MECPP的总和与瘦素水平(β= -0.14,95%CI:-0.27,-0.01;β= -0.12,95%CI:-0.24,0.00,具显着意义;β= 0.08,95%CI:-0.14,-0.03;和β= -0.09,95%CI:-0.16,-0.03)。本研究提供了一些证据,表明产前暴露于双酚A和某些邻苯二甲酸盐可能会改变胎儿脂联素和瘦素的水平。双酚A的水平与瘦素水平呈负相关(β= -0.06,95%置信区间[CI]:-0.11,-0.01),但与高分子量脂联素水平呈正相关,具有边际意义(β= 0.03,95%CI:0.00,0.06)。邻苯二甲酸单异丁酯(MiBP),邻苯二甲酸单正丁酯(MnBP),邻苯二甲酸单-(2-乙基己基)酯(MEHP)以及表示DEHP暴露(∑DEHPm)的MEHP和MECPP的总和与瘦素水平(β= -0.14,95%CI:-0.27,-0.01;β= -0.12,95%CI:-0.24,0.00,具显着意义;β= 0.08,95%CI:-0.14,-0.03;和β= -0.09,95%CI:-0.16,-0.03)。本研究提供了一些证据,表明产前暴露于双酚A和某些邻苯二甲酸盐可能会改变胎儿脂联素和瘦素的水平。双酚A的水平与瘦素水平呈负相关(β= -0.06,95%置信区间[CI]:-0.11,-0.01),但与高分子量脂联素水平呈正相关,具有边际意义(β= 0.03,95%CI:0.00,0.06)。邻苯二甲酸单异丁酯(MiBP),邻苯二甲酸单正丁酯(MnBP),邻苯二甲酸单-(2-乙基己基)酯(MEHP)以及表示DEHP暴露(∑DEHPm)的MEHP和MECPP的总和与瘦素水平(β= -0.14,95%CI:-0.27,-0.01;β= -0.12,95%CI:-0.24,0.00有边际意义;β= 0.08,95%CI:-0.14,-0.03;和β= -0.09,95%CI:-0.16,-0.03)。本研究提供了一些证据,表明产前暴露于双酚A和某些邻苯二甲酸盐可能会改变胎儿脂联素和瘦素的水平。
