孕妇和新生儿碘缺乏病研究　Ⅲ.孕妇和新生儿尿碘的相关性探讨

A Study on iodine denciency in pregnant women and newborns, Ⅲ. A research on the relation of urine iodine between pregnant women and newborns

本文采用硫酸铈法测定了1887例分娩前（40周）孕妇与相应的1887例新生儿尿碘。孕妇总体平均尿碘（206．8±109．15μg／L）高于新生儿总体平均尿4（172．7±82．30μg／L）有非常显著差异（P＜0．001）。各组孕妇与其相应新生儿平均尿碘间呈正相关（r=0．8866，P＜0．002），但孕妇尿碘在32．2－122．1μg／L时，相应新生儿尿碘高于此范围（82．2－143．8μg／L）；孕妇尿碘在173．2－431．0μg／L时，新生儿尿碘则低于此范围（150．1－218．0μg／L）均有非常显著差异（P＜0．001）。结果提示，新生儿（或胎儿）遗传控制程序有别于孕妇，各自负责自身碘代谢水平的调节。

OUr goal was to determine urine iodine of 1887 pregnant women and 1887 corresponding newborns with cerous sulfate reducing reaction. We found the average level of urine iodine in pregnant women (206. 8 ± 109. 15ug/L) was significantly higher than in newborns(172. 7 ± 82. 30ug/L), and the urine iodineof every pregnant women grouP was positively interrelated to thecorresponding newborns (r = 0. 8866, P< 0. 002). The urine iodine of pregnant women changed from 32. 2ug/L to 122. 1ug/Lwhile the urine iodine of newborns was higher and changer from82. 2μg/L to 143. 8μg/L. The urine iodine of pregnant womenchanged from 173. 2μg/L to 431. 0μg/L, the urine iodine ofneWbornS was lower and changed from 150. 1μg/L to 218.0 μg/L. thee differences were all previous (p<0.001). The resultsrevealed that the genetic system of new borns is different frompregnant women and they had their own iodine metabolism.
