目的:进一步了解北海市人群碘营养状况及病情消长趋势,逐步建立碘缺乏病监测系统,为制定消除碘缺乏病综合防治措施提供依据。方法:采用人口比例概率法(PPS)进行抽样。结果:采集居民家庭食盐600份,含碘盐比例为53%,非碘盐比例为47%。采用触诊法和B超法检查1 194名8～10岁儿童,甲状腺肿大率分别为1.34%和3.1%。采集、测定8～10岁儿童尿样1 194份,尿碘中位数为191μg/L。测试1 194名8～10岁儿童智商,平均智商为98.3。采集、测定育龄妇女尿样302份,尿碘中位数为132.5μg/L。结论:由于受非碘盐的影响,居民碘盐覆盖率低。人群碘营养状况、儿童碘营养状况良好,育龄妇女整体尿碘水平达国家消除标准的尿碘要求,但有个别县、区未达国家消除标准尿碘要求,今后应加强健康教育宣传工作,提高群众防病意识,使群众自觉使用碘盐。同时加大与盐业部门的合作,构筑联合力量,有力打击非碘盐冲击市场,让群众都吃上合格碘盐。 OBJECTIVE: To further understand the iodine nutrition status and the trend of disease progression in Beihai, and to gradually establish a monitoring system for iodine deficiency disorders to provide a basis for formulating comprehensive prevention and control measures for iodine deficiency disorders. Methods: Population proportion of probability (PPS) sampling. Results: 600 household salt samples were collected. The iodine salt content was 53% and the non-iodine salt content was 47%. A total of 1 194 children aged 8 to 10 years were examined by palpation and B-ultrasonography. The rates of goiter were 1.34% and 3.1% respectively. A total of 1 194 urine samples from 8 to 10 years old children were collected, and the median urinary iodine was 191 μg / L. Test 1 194 children aged 8 to 10 with IQ of 98.3. A total of 302 urinary samples from women of childbearing age were collected and the urinary iodine median was 132.5μg / L. Conclusion: Due to the impact of non-iodized salt, residents have low coverage of iodized salt. Iodine nutritional status of the population, iodine nutritional status of children is good, the overall urinary iodine levels of women of childbearing age reached the national standard of urinary iodine elimination requirements, but some counties and districts have not reached the national standard urinary iodine elimination requirements, health education should strengthen publicity work in the future to improve The public awareness of disease prevention, so that people consciously use iodized salt. At the same time increase cooperation with the salt industry departments to build a joint force, a strong fight against non-iodized salt impact the market, so that the masses eat qualified iodized salt.
