德江县2022年碘缺乏病监测结果分析及监督管理对策

Analysis of Monitoring Results of Iodine Deficiency Disease in Dejiang County in 2022 and Countermeasures for Supervision and Management

目的分析德江县2022年重点人群碘营养水平,对碘缺乏病结果分析,并有针对性地提出监督管理对策。方法德江县于2022年5—7月开展重点人群碘营养水平监测,在每个片区各随机抽取1个乡镇/街道(包括泉口镇、共和镇、平原镇、煎茶镇、安化街道办事处,每个乡镇/街道各抽取1所小学校,每所小学抽取40名8~10岁非寄宿学生;每个乡镇/街道抽取20名孕妇,分别检测尿碘、盐碘含量。)结果德江县2022年共监测300名学生和孕妇的碘营养水平,包括8~10岁非寄宿学生200名、孕妇100名。居民食盐碘含量>39 mg/kg的有2名,<21 mg/kg的有12名,合格碘盐覆盖率为95.3%。8~10岁儿童尿碘检测200份,儿童尿碘中位数为196.3μg/L,其中尿碘值<100、100~200、>200、≥300μg/L分别有35名、70名、62名、33名。采集孕妇尿碘检测100份,尿碘中位数155.9μg/L,其中尿碘值<150、150~250、>250、≥500μg/L分别有48名、26名、21名、5名。结论德江县2022年居民合格碘盐食用率、儿童及孕妇尿碘水平、儿童甲状腺容积等监测指标均达到消除碘缺乏病控制标准,继续保持消除碘缺乏病可持续发展状态。

Objective To analyze the iodine nutrition level of key population in Dejiang County in 2022,analyze the results of iodine deficiency disease,and put forward targeted supervision and management measures.Methods Dejiang County will carry out iodine nutrition monitoring of key population from May to July 2022,and randomly select 1 township/street in each area(including the towns where the county city is located,the townships are Quankou Town,Gonghe Town,Pingyuan Town,Jiaancha Town and Anhua Sub-district).One primary school was selected from each town/street,and 40 non-boarding students aged 8-10 were selected from each primary school.Twenty pregnant women were selected from each of the five towns/streets to detect the contents of urine iodine and salt iodine respectively.Results In 2022,300 students and pregnant women in Dejiang County were monitored for iodine nutrition,including 200 non-boarding students aged 8 to 10 and 100 pregnant women.There were 2 residents with iodine content>39 mg/kg and 12 with iodine content<21 mg/kg,and the qualified iodized salt coverage rate was 95.3%.200 urine iodine samples were collected from 8 to 10 years old children,and the median urine iodine was 196.3μg/L,among which 35,70,62,and 33 urine iodine values were<100μg/L,100-200μg/L,>200μg/L,and≥300μg/L,respectively.100 urine iodine samples were collected from pregnant women,and the median urine iodine was 155.9μg/L,among which 48,26,21,and 5 urine iodine values were<150μg/L,150-250μg/L,>250μg/L,and≥500μg/L.Conclusion The monitoring indicators such as the qualified iodized salt consumption rate,the urine iodine level of children and pregnant women,and the thyroid volume of children in Dejiang County in 2022 have reached the control standard of eliminating iodine deficiency disease,and continue to maintain the sustainable development status of eliminating iodine deficiency disease.
