摘要
目的了解福州市重点人群碘营养状况,为调整干预策略提供科学依据。方法2021年3-10月,在福州市12个县(市、区)开展重点人群碘营养状况调查。每个县(市、区)按东、西、南、北、中方位划分5个抽样片区,每个片区抽取1个乡镇(街道),每个乡镇(街道)抽取1所小学的40名8~10岁非寄宿制儿童(年龄均衡、男女各半)和20名孕妇(孕早、中、晚期均衡)作为调查对象。采集调查对象家庭食用盐盐样和随机尿样,采用直接滴定法、砷铈催化分光光度法分别检测盐碘、尿碘含量;B超法测定儿童甲状腺容积。同时,采用与福州市妇幼保健院合作方式,收集福州市2021年足月顺产新生儿足跟血促甲状腺激素(thyroid stimulating hormone,TSH)检测结果。结果共对2400名儿童进行盐碘、尿碘、甲状腺肿大监测,盐碘中位数为24.40 mg/kg,碘盐覆盖率为93.04%(2233/2400),碘盐合格率为97.40%(2175/2233),合格碘盐食用率为90.62%(2175/2400);尿碘中位数为181.47μg/L;甲状腺肿大率为1.04%(25/2400)。共对1200名孕妇进行盐碘、尿碘监测,盐碘中位数为24.10 mg/kg,碘盐覆盖率为91.08%(1093/1200),碘盐合格率为97.90%(1070/1093),合格碘盐食用率为89.17%(1070/1200);尿碘中位数为128.10μg/L。14242份新生儿足跟血TSH水平中位数为3.38 mU/L,TSH水平>5 mU/L的比例为30.96%(4410/14242)。结论2021年,福州市儿童处于碘适宜水平,但孕妇碘营养不足。应继续保持以食盐加碘为主的综合防治措施,针对孕妇开展健康教育,同时加强新生儿TSH水平监测。
Objective To investigate the iodine nutrition status of key population in Fuzhou City,and to provide scientific basis for adjusting intervention strategies.Methods From March to October 2021,a survey was conducted on iodine nutrition status of key population in 12 counties(cities,districts)of Fuzhou City.Each county(city,district)was divided into 5 sampling areas according to the east,west,south,north and middle directions.One township(street)was selected from each area,and 40 non-boarding children aged 8-10(age balanced,half male and half female)from one primary school and 20 pregnant women(early,middle and late pregnancy balanced)were selected as survey subjects.Household salt samples and random urine samples were collected,and the salt iodine and urine iodine levels were tested by direct titration and arsenic and cerium catalytic spectrophotometry,respectively.Children's thyroid volume was measured by B-ultrasonography.At the same time,in cooperation with Fuzhou Maternal and Child Health Hospital,the thyroid stimulating hormone(TSH)testing results of heel blood of full-term natural delivery newborns in Fuzhou City in 2021 were collected.Results A total of 2400 children were monitored for salt iodine,urine iodine and goiter.The median salt iodine was 24.40 mg/kg,with an iodine salt coverage rate of 93.04%(2233/2400),a qualified rate of iodized salt of 97.40%(2175/2233),and a consumption rate of qualified iodized salt of 90.62%(2175/2400).The median urine iodine was 181.47μg/L.The rate of goiter was 1.04%(25/2400).A total of 1200 pregnant women were monitored for salt iodine and urine iodine.The median salt iodine was 24.10 mg/kg,the coverage rate of iodized salt was 91.08%(1093/1200),the qualified rate of iodized salt was 97.90%(1070/1093),and the consumption rate of qualified iodized salt was 89.17%(1070/1200).The median urine iodine was 128.10μg/L.The median TSH level in the heel blood of 14242 newborns was 3.38 mU/L,and the proportion of TSH level>5 mU/L was 30.96%(4410/14242).Conclusions In 2021,children in Fuzhou City are at an appropriate level of iodine,but pregnant women are insufficient of iodine.We should continue to maintain comprehensive prevention and control measures mainly based on salt iodization,provide health education for pregnant women,and strengthen monitoring of TSH level in newborns.
