JCEM:产前暴露于对羟基苯甲酸丁酯与7岁男孩的体脂百分比有关

2021-03-27 MedSci原创 MedSci原创

被认为毒性较低的对羟基苯甲酸酯在发育期可能会影响肥胖症的发生。

对羟基苯甲酸酯在食品中作为防腐剂,但其被怀疑可能具有破坏内分泌功能的特性。最近的一项研究报道,孕妇宫内对羟基苯甲酸丁酯暴露与儿童期超重之间存在相关性,而在女孩中相关性更强。

近日,内分泌和代谢性疾病领域权威杂志Journal of Clinical Endocrinology & Metabolism上发表了一篇研究文章,这项研究旨在评估妊娠晚期孕妇尿液中对羟基苯甲酸酯水平与子女7岁时脂肪百分比之间的关系。

研究人员使用了欧登塞儿童队列的数据,该队列是2010-2012年期间招募的母婴队列,并随访了这些孩子。在妊娠中位28.7周时,研究人员测量了孕妇尿液中对羟基苯甲酸酯的浓度,并通过双X线吸收法评估7岁时儿童体内脂肪百分比。

研究人员发现受试者对羟基苯甲酸酯暴露量很低。在多元线性回归中,相比于母亲尿液中没有检测到对羟基苯甲酸丁酯的男孩,孕妇尿液中对羟基苯甲酸丁酯检测阳性与7岁儿童总体脂百分比增加17%(95%置信区间CI为3.0%; 32%)和7岁男孩增加23%(95%CI为5.1%; 43)相关。没有发现宫内暴露于对羟基苯甲酸甲酯、对羟基苯甲酸乙酯或对羟基苯甲酸丙酯与身体组分之间有显著关联,并且在女孩中也没有发现显著关联。

由此可见,被认为毒性较低的对羟基苯甲酸酯在发育期可能会影响肥胖症的发生。
