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。仅依赖食盐补碘对孕早期妇女已不能满足需要
Objective To explore the main influence of iodine nutrition changes and pregnancy reaction in early pregnancy. Methods The pregnancy response questionnaire and morning urine of pregnant women in the first trimester were enrolled in this urban area for more than 3 consecutive years with medium economic income. The urine iodine was determined by GB / T - 1998. Results Early pregnancy group had urinary iodine (G) 14 6 5 μg / L, which was significantly lower than those in the same age nonpregnant group and the second trimester group (2 93 9 μg / L and 182 6 μg / L 0 01). The difference of urinary iodine (113 0 μg / L and iodine <10 0 μg / L) in pregnancy-positive group was significantly different from that in pregnancy-negative group (21 8μg / L and 27%) Sexual significance (P <0 0 1). Conclusions There is a decrease of iodine nutrition level at the end of early pregnancy, and the pregnancy response has a synergistic effect on this. Only relying on salt iodization of pregnant women can not meet the needs of early
