辽宁省沿海地区重点人群碘营养状况调查

目的了解全民食盐加碘后辽宁省沿海地区怀孕妇女、哺乳妇女、0￣2岁婴幼儿和学龄儿童等重点人群的碘营养状况。方法测定上述重点人群的尿碘、食用盐碘并检查学龄儿童甲状腺肿大情况。结果沿海地区实施全民食盐加碘后,儿童尿碘中位数为188.21μg/L,孕妇为159.69μg/L,哺乳妇女为164.16μg/L,0～2岁婴幼儿尿碘中位数195.4μg/L,其尿碘值低于20μg/L的比例均在10%以下。结论实施全民食盐加碘后,重点人群的碘营养状况得到显著改善,碘营养处于适宜水平。但相对于学生人群,孕妇和哺乳妇女的尿碘水平明显向低值转移。在人群总体碘营养状况较好的情况下,仍有相当部分的孕妇、哺乳妇女的碘营养未达到理想水平,需引起重视。建议在今后监测工作中,还需加强对孕妇、哺乳妇女等特需人群的碘营养监测。

Study on the state of iodine nutrition in target population in the coastal area of Liaoning Province

Objective To investigate the status of iodine nutrition of pregnant or lactating women, infants and children in the coastal area after implementing universal salt iodization(USI). Methods Goiter was detected by palpation and ultrasound. Urine iodine and salt iodine were measured, respectively. Results After implementing USI, the status of iodine nutrition of risk population was improved obviously. However, compared with the children, the levels of iodine nutrition of pregnant women and lactating women were lower. Conclusion After implementing USI, the status of iodine nutrition in risk population has been promoted obviously, the levels of iodine nutrition in pregnant women and lactating women are still lower than that of normal range. The surveillance of iodine nutrition of pregnant women and lactating women should be strengthened.
