碘营养充足地区孕早期尿碘含量及妊娠反应关系

Relation Between Urine Iodine Content and Morning Sickness of Early-stage Pregnant Women in Iodine Sufficient Area

目的 探索孕早期碘营养变化及妊娠反应的主要影响。方法 一次收集在本市区内连续居住 3年以上、经济收入中等水平的孕早期妇女妊娠反应问卷及晨尿 ,采用GB/T - 1998测定尿中碘。结果 早孕组尿碘 (G) 14 6 5 μg/L ,极显著低于同龄未孕组和孕中期组 (2 93 9μg/L和 182 6 μg/LP均 <0 0 1)。妊娠反应阳性组尿碘 (113 0 μg/L和碘<10 0 μg/L有 2 9 8% ) ,与妊娠反应阴性组 (2 2 1 8μg/L和 2 7% )的差异均有极显著性意义 (P均 <0 0 1)。结论 妊娠早期末就有碘营养水平下降的发生 ,妊娠反应对此有协同作用。

Objective To probe the main influence factors of changes of iodine nutrition and its morning sickness in early stage of pregnant women.Methods To collect questionnaires and morning urine in early stage of pregnant women who lived in the center of city for more than three years,and use method of GB/T 1998 to measure urine iodine content.Results The urine iodine content of early stage of pregnant women(G)(146 5μg/L)was quite obviously lower than non pregnant women of the same age and middle-stage pregnant women(293 9μg/L and 182 6μg/L P \-\{av\}<0 01).There were statistical significant differences between the urine iodine content of early-stage pregenant women who had morning sickness (113 0μg/L and urine iodine content<100μg/L,29 8%)and non pregnant women (221 8μg/L and 2 7% P \-\{av\}<0 01).Conclusion There was a straight relation between decrease of urine iodine content in the last-stage of early pregnant women and its morning sickness.Therefore it cannot satisfy the needs of early-stage of pregnant women,to depend on salt to replenish iodine.
