摘　　要：目的了解山东省沿海县(市、区,以下简称县)碘盐普及情况,评价儿童、孕妇碘营养状况,为适时采取针对性防治措施和科学调整干预策略提供数据支撑。方法2021年在山东省37个沿海县,每个县按东、西、南、北、中5个方位各抽取1个乡镇,每个乡镇抽取1所小学,每所小学抽取6~12岁非寄宿儿童40人,另在每个乡镇抽取20名孕妇作为调查对象,采集家庭食用盐盐样和尿样,检测盐碘和尿碘含量;选取19个县,采用B超法检测抽中儿童甲状腺容积,计算儿童甲状腺肿大率。结果共检测儿童家庭食用盐盐样7736份,碘盐覆盖率为74.3%(5746/7736),碘盐合格率为74.3%(4267/5746),合格碘盐食用率为55.2%(4267/7736);共检测儿童尿样7740份,尿碘中位数为174.0μg/L;共检测儿童甲状腺4344例,甲状腺肿大率为3.0%(131/4344)。共检测孕妇家庭食用盐盐样4513份,碘盐覆盖率为83.7%(3779/4513),碘盐合格率为77.6%(2933/3779),合格碘盐食用率为65.0%(2933/4513);共检测孕妇尿样7740份,尿碘中位数为133.5μg/L。结论山东省37个沿海县儿童总体处于碘适宜水平,但孕妇还存在碘营养不足的风险,需持续落实碘缺乏病综合防治措施,巩固深化碘缺乏防治成果。Objective To learn about the prevalence of iodized salt in coastal counties(cities and districts,hereinafter referred to as counties)of Shandong Province,evaluate the iodine nutritional status of children and pregnant women,so as to provide data support for timely targeted prevention and control measures and scientific adjustment of intervention strategies.Methods In 2021,in 37 coastal counties of Shandong Province,one township was selected from each of the five directions of the east,west,south,north,and middle of each county,one primary school was selected from each township,40 non-boarding students aged 6-12 years old were selected from each primary school.In addition,20 pregnant women were selected from each township.Children's and pregnant women's household salt samples and urine samples were collected to detect salt iodine and urinary iodine contents.The children from 19 counties selected from the 37 coastal counties of Shandong Province were examined by B-mode ultrasound,and the goiter rate of children was calculated.Results Totally 7736 household edible salt samples from the children were tested,and the coverage rate of iodized salt,iodized salt qualified rate and qualified iodized salt consumption rate was 74.3%(5746/7736),74.3%(4267/5746)and 55.2%(4267/7736),respectively.A total of 7740 urine samples were collected from the children,the median urinary iodine was 174.0μg/L.A total of 4344 children were selected for thyroid examination,and the goiter rate was 3.0%(131/4344).Totally 4513 household edible salt samples from the pregnant women were tested,and the coverage rate of iodized salt,iodized salt qualified rate and qualified iodized salt consumption rate was 83.7%(3779/4513),77.6%(2933/3779)and 65.0%(2933/4513),respectively.A total of 7740 urine samples were collected from the pregnant women,the median urinary iodine was 133.5μg/L.Conclusions Children in 37 coastal counties of Shandong Province are generally at the appropriate level of iodine,but pregnant women still have the risk of iodine deficie
