目的:了解温州市瓯海区孕妇的尿碘水平,为碘缺乏病防治工作提供科学依据。方法:选取560例孕妇作为研究对象,进行尿碘检测。结果:尿碘中位数为153.8μg/L,其中尿碘<100μg/L者所占比例为25.89%,尿碘<50μg/L者占6.25%。缺碘率为47.86%。在孕早、中、晚期孕妇中尿碘中位数分别为159.5μg/L、153.9μg/L、138.9μg/L,各孕期尿碘水平比较,无显著性差异(χ2=6.0,P>0.05)。在20岁～25岁、26岁～30岁、31岁～43岁的年龄组中,尿碘中位数分别为149.9μg/L、157.7μg/L、170.8μg/L,各年龄组尿碘水平比较,无显著性差异(χ2=10.08,P>0.05)。结论:瓯海区孕妇碘营养虽然状况良好,达到消除碘缺乏病的标准,但尿碘中位数处在标准值的边缘且缺碘率较高,应重视对孕妇尿碘水平的监测,指导其科学补碘。
Objective: To understand the urinary iodine level of pregnant women in Ouhai District of Wenzhou City, and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods: 560 pregnant women were selected as the research object for urinary iodine detection. Results: The median urinary iodine was 153.8μg / L, of which urine iodine <100μg / L accounted for 25.89%, urinary iodine <50μg / L accounted for 6.25%. The iodine deficiency rate was 47.86%. The median urinary iodine was 159.5μg / L, 153.9μg / L and 138.9μg / L respectively in pregnant women with early, middle and late stages of pregnancy. There was no significant difference in urinary iodine levels during pregnancy (χ2 = 6.0, P> 0.05 ). The median urinary iodine was 149.9μg / L, 157.7μg / L and 170.8μg / L in the age groups of 20-25, 26-30, 31-43 respectively. The urinary iodine in all age groups There was no significant difference between the two groups (χ2 = 10.08, P> 0.05). Conclusion: Although the iodine nutrition of pregnant women in Ouhai District is in good condition and reaches the standard of eliminating iodine deficiency disorders, the median of urinary iodine is at the edge of the standard value and the iodine deficiency rate is high. Therefore, the monitoring and guidance of urinary iodine level in pregnant women should be emphasized Its scientific supplement of iodine.
