妊娠妇女碘营养状况调查

目的研究不同孕期妇女碘营养状况，为妊娠期是否需要补碘提供依据。方法采用过氧乙酸氧化四甲基联苯胺显色法测定3052例妊娠妇女尿碘水平。结果孕妇尿碘中位数为183．2μg／L，缺碘发生率达22．3％，明显高于非妊娠妇女（8．0％），尿碘值50-100μg/L者630例占20．6％，〈50μg／L者51例，占1．7％。妊娠期缺碘分布集中于8～15^＋6和34～39^＋6孕周组。结论①孕妇存在一定缺碘状况，有必要进行尿碘筛查。②重点监测16孕周前和34孕周后的碘营养状况。

Iodine Nutritional Status of Pregnant Women

Objective To investigate the iodine nutritional status of pregnant women in Shougnang area. Methods The peracetic acid oxidation of tetramethylbenzidine chromogenic determination was used for urine iodine level of 3052 pregnant women. Results The median of urinary iodine was 183.2μg/L in the pregnant women. The incidence of iodine deciffeiency was 22.3% ,significantly higher than that of non-pregnancy（8.0%）, and 630 cases showed that urinary iodine was 50-100 μg/L, accounting for 20.6%, and 51 cases showed it was less than 50 μL g/L,accounting for 1.7%. Iodine deficiency during pregnancy focused on between 8-15^＋6 and 34-39^＋6 gestational weeks. Conclusion ①Tbere is a certain lack of iodine status of pregnant women in Shouguang area, and therefore, there is a need for screening of urinary iodine. ②We should focus on monitoring the iodine nutrition status before 16 gestational weeks and after 34 gestational weeks in pregnant women.
