摘　　要：目的:探讨2018—2022年龙口市8~10岁儿童碘营养状况,为今后开展碘缺乏病防治工作提供依据。方法:2018—2022年,采取分层抽样与单纯随机抽样相结合的抽样方法,每年在龙口市按方位抽取5所小学,在每所小学抽取8~10岁的非寄宿学生40人,累计1000人,采集该群学生的随机中段尿样及家庭中所用食盐样品,检测尿碘含量及盐碘含量。结果:2018—2022年龙口市8~10岁儿童尿碘中位数分别为147.25μg/L、174.13μg/L、161.45μg/L、138.75μg/L、104.84μg/L,均处于碘适宜水平。盐碘中位数分别为20.95 mg/kg、21.10 mg/kg、21.10 mg/kg、18.10 mg/kg、20.10 mg/kg,均处于合格碘盐水平。各年份的碘盐覆盖率总体处于下降趋势。食用加碘食盐的儿童群体尿碘中位数高于食用非碘盐的儿童群体尿碘中位数,差异有统计学意义(P<0.05)。结论:龙口市儿童碘营养水平总体处于适宜水平,但儿童尿碘中位数及合格碘盐食用率处于下降趋势,应加强学校、社区、医疗机构等场所教育宣传,倡导普通家庭使用加碘食盐,以保障儿童群体的碘营养水平。Objective To investigate the iodine nutrition status of 8-10-year-old children in Longkou City from 2018 to 2022,providing basis for future prevention and control of iodine deficiency disorders.Methods From 2018 to 2022,a combined method of stratified sampling and simple random sampling was used.Five primary schools were selected annually in Longkou City,and 40 nonboarder students aged 8-10 were randomly selected from each school,totaling 1000 participants.Random midstream urine samples and household salt samples were collected from the students,and urinary iodine content and salt iodine content were measured.Results The median urinary iodine concentrations of 8-10-year-old children in Longkou City from 2018 to 2022 were 147.25μg/L,174.13μg/L,161.45μg/L,138.75μg/L,and 104.84μg/L,respectively,all within the adequate iodine level.The median salt iodine concentrations were 20.95 mg/kg,21.10 mg/kg,21.10 mg/kg,18.10 mg/kg,and 20.10 mg/kg,respectively,all within the qualified iodized salt level.The iodized salt coverage rate showed a decreasing trend over the years.The median urinary iodine concentration of children consuming iodized salt was significantly higher than that of children consuming non-iodized salt.The difference is statistically significant(P<0.05).Conclusions The iodine nutrition status of children in Longkou City is generally adequate.However,the median urinary iodine concentration and the rate of consuming qualified iodized salt are declining.Education and promotion efforts in schools,communities,medical institutions,etc.,advocating for the use of iodized salt in ordinary households,are necessary to ensure the iodine nutrition status of children.
