Recent evidence suggests that endocrine disrupting chemicals (EDCs) may cause perturbations in endogenous hormonal regulation that predispose to weight gain. Using data from NHANES (1999-2002), we investigated the association between body mass index (BMI), waist circumference (WC) and selected persistent organic pollutants (POPs) via multiple linear regressions. Consistent interaction was found between gender, ln oxychlordane and ln p,p' DDT. Also, we found an association between WC and ln oxychlordane and ln hpcdd in subjects with detectable levels of POPs, whereas an association between WC and ln p,p' DDT was observed in all subjects. Furthermore, ln Ocdd showed an increase with higher WC and BMI, whereas, ln trans-nonachlor decreased with higher BMI. Hence, BMI and WC are associated with POPs levels, making the chemicals plausible contributors to the obesity epidemic.
最近的证据表明,内分泌干扰化学物质(EDCs)可能会导致内源性激素调节紊乱,从而导致体重增加。本研究利用 NHANES(1999-2002 年)的数据,通过多元线性回归分析了体重指数(BMI)、腰围(WC)与选定持久性有机污染物(POPs)之间的关系。研究发现,性别、ln 氧氯丹和 ln p,p' DDT 之间存在一致性交互作用。此外,在可检测到 POPs 的人群中,WC 与 ln 氧氯丹和 ln hpcdd 之间存在关联,而在所有人群中,WC 与 ln p,p' DDT 之间存在关联。此外,lnOcdd 随着 WC 和 BMI 的升高而增加,而 ln 反式-十氯酮则随着 BMI 的升高而降低。因此,BMI 和 WC 与 POPs 水平相关,这些化学物质可能是肥胖流行的原因之一。
