Organochlorine pesticides (OCPs) in placental tissue have been reported to be associated with an increased risk for fetal neural tube defects (NTDs). Our case-control study was performed to explore the association between maternal serum OCP concentration and NTD risk in offspring. Serum samples were collected from 117 mothers who delivered NTD infants (case group) and 121 mothers who delivered healthy infants (control group). Only three of the 25 OCPs were detected in more than half of the maternal serum samples. The median concentration of total OCPs in the case group was significantly higher than that of the control group. However, no dose-response relationships between higher levels of any individual OCPs or total OCPs and the risk of NTDs or subtypes were observed in either the unadjusted binary unconditional logistic regression model or the model adjusted by potential confounders. We conclude that no clear association between maternal serum OCP residues and NTD risk in offspring was observed in this population.
No clear association between maternal serum levels of organochlorine pesticides and risk of neural tube defects in offspring was observed for a Chinese population.
据报道,胎盘组织中的有机氯农药(OCPs)与胎儿神经管缺陷(NTDs)风险增加有关。我们进行了病例对照研究,以探讨母体血清中OCP浓度与后代NTD风险之间的关联。从117名分娩NTD婴儿的母亲(病例组)和121名分娩健康婴儿的母亲(对照组)中采集血清样本。在超过一半的母体血清样本中仅检测到25种OCP中的3种。病例组中总OCP的中位数浓度显著高于对照组。然而,在未调整的二元无条件逻辑回归模型或由潜在混杂因素调整的模型中,均未观察到任何个体OCP或总OCP水平升高与NTDs或其亚型风险之间的剂量反应关系。我们得出结论,在该人群中未观察到母体血清OCP残留与后代NTD风险之间存在明确关联。
对于中国人群,未观察到母体血清中有机氯农药水平与后代神经管缺陷风险之间存在明确关联。
