In Asturias, where iodine deficiency was eradicated in school children by the year 2000, iodine deficiency persisted in pregnant women, who were recommended to use of iodine supplementation. The aim of this study was to determine the iodine nutrition of pregnant women in our area and whether or not iodine supplements are needed.
Throughout May and June 2013 we studied the iodine nutrition and thyroid function during the first trimester of pregnancy in 173 women in the health area of Oviedo.
The median urinary iodine was 197 μg/L. Iodinated supplements were used by 47% of women, which had a yoduria median higher than those not taking iodinated supplements (247 vs. 138 μg/L; p<.001), and also a higher TSH (2.30 vs 1.94 mU/L) although not significantly different. Yoduria was also higher in women who took more than 2 servings of dairy products (median: 230 μg/L) than those who took less (median: 191 μg/L). Within the group of women who were not taking iodine supplements, those regularly using iodized salt in the kitchen (47%) had a median urinary iodine concentration of 190μg/L indicating iodine sufficiency.
Iodinated supplements seem unnecessary nowadays in pregnant women of Oviedo who regularly take iodized salt and our recommendation in these cases should be to continue the use of iodized salt in the recommended amounts during pregnancy and consume at least two daily servings of milk or dairy products.
在阿斯图里亚斯地区，2000年学龄儿童碘缺乏问题已得到根除，但孕妇中碘缺乏现象依然存在，因此建议孕妇补充碘。本研究旨在确定我们地区孕妇的碘营养状况以及是否需要补充碘剂。
2013年5月至6月期间，我们对奥维耶多健康区的173名孕早期妇女的碘营养状况和甲状腺功能进行了研究。
尿碘中位数为197μg/L。47%的妇女使用了含碘补充剂，其尿碘中位数高于未服用含碘补充剂的妇女（247 vs. 138μg/L；p<0.001），促甲状腺激素水平也更高（2.30 vs 1.94mU/L），不过差异不显著。摄入两份以上乳制品的妇女尿碘水平（中位数：230μg/L）也高于摄入量较少的妇女（中位数：191μg/L）。在未服用碘补充剂的妇女组中，经常在厨房使用加碘盐的妇女（47%）尿碘浓度中位数为190μg/L，表明碘充足。
对于奥维耶多地区经常食用加碘盐的孕妇来说，目前似乎没有必要服用含碘补充剂，我们建议这些孕妇在孕期继续按推荐量食用加碘盐，并每天至少食用两份牛奶或乳制品。
