Fetal, Neonatal And Childhood Effects Of In Utero Exposure To PCB And DDE

发表在2007财年的研究表明，尽管先前对人类和动物的研究结果具有提示性，但六氯苯(优势比1.1，95%CI 0.6-2.0)、七氯环氧化物(优势比1.2，95%CI 0.6-2.6)和β-环己烷(优势比1.6，95%CI 0.7-3.6)都与隐睾症无关。 根据出生前接触DDE的情况，其他工作评估了儿童时期的发育。与母亲在妊娠晚期血清DDE浓度最低的孩子(每升低于15微克)相比，母亲每升至少60微克的孩子在1、4和7岁时较矮。然而，母亲处于中等水平的孩子在身高上没有差异。

Work published in FY2007 indicated that, in spite of previously suggestive results in humans and animals, neither hexachlorobenzine (odds ratio 1.1, 95 percent CI 0.6-2.0), heptachloroepoxide (odds ratio 1.2, 95 percent CI 0.6-2.6), nor beta-exachlorocyclohexane (odds ratio 1.6, 95 percent CI 0.7-3.6) were associated with cryptorchidism. Additional work evaluated growth during childhood according to prenatal exposure to DDE. Compared to children whose mothers had the lowest serum concentrations of DDE in the third trimester (less than 15 micrograms per liter), children of mothers with concentrations of at least 60 micrograms per liter were shorter at 1, 4 and 7 years. However, there were no differences in height for children whose mothers had intermediate levels.
