摘　　要：目的分析2005—2021年江苏省苏州市吴江区居民碘营养状况。方法将苏州市吴江区辖区划分为东、西、南、北、中5个片区,每年随机抽取片区内一定数量的家庭户、孕妇及8~10周岁儿童。采集家庭户食盐样本以及孕妇、儿童随机尿样,采用B超监测儿童甲状腺容积,计算盐碘、尿碘中位数。结果2005—2021年,平均合格碘盐食用率为95.59%(4795/5016),平均碘盐合格率为97.46%(4795/4920),平均非碘盐率为1.91%(96/5016),盐碘中位数为27.91 mg/kg。碘盐新标准实施后,盐碘中位数下降,差异有统计学意义(P<0.01)。儿童甲状腺肿大率为0.93%,尿碘中位数为204.10μg/L;降碘后,儿童尿碘中位数下降,差异有统计学意义(P<0.05),尿碘浓度≥300μg/L者比率下降,差异有统计学意义(P<0.01)。2005—2021年孕妇尿碘中位数为154.96μg/L,尿碘浓度<150μg/L者比率为54.42%。结论2005—2021年苏州市吴江区碘盐普及率较高,孕妇和儿童碘营养处于适宜水平。降碘后,儿童碘过量风险降低,但仍有部分孕妇处于碘缺乏水平,建议加快推进孕妇分类碘盐政策,保障孕期碘盐生理需求。Objective To analyze the iodine nutritional status of residents from 2005 to 2021 in Wujiang District of Suzhou City of Jiangsu Province.Methods Wujiang District of Suzhou City was divided into five areas:east,west,south,north and middle areas,and a certain number of households,pregnant women and children aged 8 to 10 in the areas were randomly selected every year.Salt samples of households and the random urine samples of pregnant women and children were collected,thyroid volume of children was monitored by B-ultrasound,and the median salt iodine and urine iodine were calculated.Results From 2005 to 2021,the average consumption rate of qualified iodized salt was 95.59%(4795/5016),the average qualified rate of iodized salt was 97.46%(4795/4920),the average non-iodized salt rate was 1.91%(96/5016),and the median salt iodine was 27.91 mg/kg.After the implementation of the new standard for iodized salt,the median salt iodine was significantly decreased(P<0.01).The rate of thyroid enlargement in children was 0.93%,and the median urinary iodine was 204.10μg/L;after reducing iodine concentration in salt,the median urinary iodine in children was significantly decreased(P<0.05),and the ratio of children with urinary iodine concentration≥300μg/L was significantly decreased as well(P<0.01).The median urinary iodine of pregnant women from 2005 to 2021 was 154.96μg/L,and the ratio of those with urinary iodine concentration<150μg/L was 54.42%.Conclusion From 2005 to 2021,the popularity rate of iodized salt in Wujiang District of Suzhou City is high,and the iodine nutrition of pregnant women and children is at an appropriate level.After reducing iodine concentration in salt,the risk of iodine excess in children is reduced,but some pregnant women are still at iodine deficiency level,so we suggest accelerating the policy of classified iodized salt for pregnant women to ensure the physiological needs of iodized salt during pregnancy.
