摘要目的研究孕妇血清中轻稀土元素含量与小于胎龄儿的关联性。方法研究对象来自2009—2013年在山西省寿阳县和平定县建立的孕期研究队列。采用巢式病例对照研究设计,纳入小于胎龄儿组126人,对照组381人。采用电感耦合等离子体质谱仪定量分析血清中稀土元素含量。结果孕期血清各轻稀土元素及轻稀土元素总量与小于胎龄儿发生风险的关联性均不具有统计学意义。根据采血日期分层分析结果显示孕早期镧、铈、镨、钐、铕与小于胎龄儿发生风险的关联性不具有统计学意义,钕元素与小于胎龄儿(粗OR=1.85;95%CI:1.06~3.25)、轻稀土元素总量与小于胎龄儿(粗OR=2.19;95%CI:1.24~3.88)具有统计学意义,调整其他混杂因素后其关联性不具有统计学意义;孕中期血清各稀土元素及轻稀土元素总量与小于胎龄儿的关联性均不具有统计学意义。结论本研究未发现孕妇血清中轻稀土元素与小于胎龄儿发生风险的关联性。

Abstract：Objective To investigate the associations between rare earth elements (REEs) in serum among pregnant women and small for gestational age birth (SGA).Methods The subjects were from the pregnancy cohort established in Shouyang County and Pingding County of Shanxi Province from 2009 to 2013. A nested case-control study design was used, a total of 126 SGA infants and 381 control subjects were included. The content of rare earth elements in serum was determined by inductively coupled plasma mass spectrometry (ICP-MS).Results There was no significant correlation between serum light REEs and the risk of SGA. When stratified by sampling time, the crude odds ratio between neodymium and SGA was 1.85 (95%CI:1.06-3.25), and the crude odds ratio between all light REEs and SGA was 2.19 (95%CI:1.24-3.88) in the first trimester. After adjusting for other confounders, there were no significant associations between light REEs and SGA. No significant associations were observed between lights REEs in the second trimester and SGA.Conclusion No significant association was found between light REEs in mother′s serum and risk of SGA.

Key words： light rare earth elements serum small for gestational age birth(SGA)
