摘要

要了解母亲食用鱼类和鱼源性有毒物质对婴儿神经发育的影响,还需要进行更多的研究。本分析是在 ECLIPSES 研究中对 460 对母婴进行的。对孕妇从鱼类(包括白鱼、蓝鱼和海鲜)中摄入的金属和持久性有机污染物进行了估算。婴儿在产后 40 天使用 Bayley 婴儿发展量表-III 进行认知、语言和运动功能评估。采用多变量线性回归模型评估了膳食毒物与结果之间的关联。据估计,产前摄入砷、无机砷、甲基汞、二恶英类多氯联苯(DL-PCBs)和非二恶英类多氯联苯等鱼源性有毒物质与婴儿较差的语言功能有关,而与运动或认知功能无明显关联。母亲的鱼类摄入量超过西班牙建议的每天不超过 71 克,会对语言能力产生不利影响,但不会影响运动或认知能力的发展。这凸显了警惕性监测环境毒物和为孕妇提供饮食指导的重要性,对公共卫生和儿童发育具有潜在影响。

Association between Prenatal Dietary Toxicants and Infant Neurodevelopment: The Role of Fish
More research is needed to understand how the maternal consumption of fish and fish-borne toxicants impacts infant neurodevelopment. The present analysis was conducted over 460 mother–infant pairs within the ECLIPSES study. Dietary intake of metals and persistent organic pollutants from fish (including white fish, blue fish, and seafood) was estimated in pregnant women. The infants underwent cognitive, language, and motor function assessments using the Bayley Scales of Infant Development-III at the 40-day postpartum. Associations between dietary toxicants and outcomes were assessed using multivariable linear regression models. Estimated prenatal exposure to fish-borne toxicants, such as arsenic, inorganic arsenic, methylmercury, dioxin-like polychlorinated biphenyls (DL-PCBs), and non-DL-PCBs, was associated with poorer language functions in infants, whereas no significant associations were found with motor or cognitive functions. Maternal fish consumption exceeding the Spanish recommendation of no more than 71 g per day was linked to these adverse effects on language abilities without affecting motor or cognitive development. This highlights the importance of vigilant monitoring of environmental toxicants and the provision of dietary guidance for pregnant women, with potential implications for public health and child development.
