摘　　要：目的通过分析2018—2022年北京市大兴区8~10岁学生碘营养监测结果,评价大兴区学生人群碘盐食用情况及效果,为调整学生人群碘缺乏病防控措施提供依据。方法2018—2022年每年均采用分层整群随机抽样方法,选取5个乡镇/街道,每个乡镇/街道各抽取1所小学校,每所小学抽取8~10岁非寄宿学生40人,收集学生随机尿样和食用盐,检测尿碘和盐碘含量,同时通过B超测量甲状腺容积,计算甲状腺肿大率。采用SPSS 22.0统计软件进行统计分析,检验水准α=0.05。结果2018—2022年共收集学生尿样标本1120份,尿碘中位数166.6μg/L为碘适宜,尿碘范围为4.3~1003.0μg/L,其中尿碘浓度<100.0μg/L的占26.70%,尿碘浓度>300μg/L的占15.63%;学生家庭碘盐中位数为21.1 mg/kg处于合格范围,家庭合格碘盐食用率呈上升趋势,全区合格碘盐覆盖率87.39%,接近90%的国家指标;学生甲状腺肿大率为2.14%,达到国家消除甲状腺肿大的标准(甲肿率<5%)。结论北京市大兴区8~10岁学生碘营养为碘适宜状态,但仍需在学生人群碘缺乏病防控中,加大食用合格碘盐的宣传力度,提高学生人群碘盐食用率,促进学生健康成长。Objective To analyze the iodine nutrition monitoring results of 8-10 year-old students in Daxing District of Beijing from 2018 to 2022,to evaluate the consumption and effectiveness of iodized salt among this population,and to provide basis for adjusting the prevention and control measures of iodine deficiency disorders among the population.Methods From 2018 to 2022,stratified cluster random sampling method was used every year to select five townships/subdistricts.One primary school was selected from each township/subdistrict.And 40 non-boarding students aged 8-10 years were selected from each primary school.Random urine samples and edible salt were collected from the students to detect urine iodine and salt iodine contents.At the same time,the thyroid volume was measured by B-ultrasound and the goiter rate was calculated.SPSS 22.0 statistical software was used for statistical analysis,and the test level wasα=0.05.Results From 2018 to 2022,a total of1120 urine samples were collected from students,with a median of 166.6μg/l of an appropriate level of iodine.The urine iodine ranged from 4.3 to 1003.0μg/l.Among them,the urine iodine concentration<100μg/l accounted for 26.70%,and the urine iodine concentration>300μg/l accounted for 15.63%.The median of iodized salt from student′families was 21.1 mg/kg,which was within the qualified range.The consumption rate of qualified iodized salt in households was on the rise.The coverage rate of qualified iodized salt in the district was 87.39%,close to 90%of the national target.The goiter rate of students was 2.14%,which met the national standard of eliminating goiter(goiter rate<5%).Conclusions The iodine nutrition of 8-10 year-old students in Daxing District of Beijing was adequate.However,in the prevention and control of iodine deficiency disorders in the student population in the future,it is still necessary to intensity the publicity of consuming qualified iodized salt,increase the consumption rate of iodized salt among students,and promote the healthy growth of stud
