为了解许昌市2012年执行食盐碘含量新标准后的碘缺乏病消长情况,根据《全国碘缺乏病监测方案》和《河南省重点人群碘营养调查方案》要求,于2013—2015年在该市开展碘盐监测、8~10岁儿童甲状腺监测及重点人群碘营养监测。结果显示,2013—2015年许昌市居民户碘盐合格率分别为92.37%,87.09%,94.17%,合格碘盐食用率分别为90.17%,85.83%,91.50%;8~10岁儿童尿碘中位数和甲状腺肿大率范围分别为143.5~218.2μg/L和0%~1.08%;哺乳期妇女和0~2岁婴幼儿尿碘中位数均>100μg/L;孕妇尿碘中位数为150~249μg/L;新婚育龄妇女尿碘中位数为100~199μg/L。提示许昌市人群碘营养处于适宜水平,现行碘盐浓度可满足绝大多数人群的碘营养需求,但仍存在非碘盐和不合格碘盐。
In order to understand the growth and decline of iodine deficiency deficiency in Xuchang City after implementing the new standard of iodine content in 2012, according to the requirements of the “National Monitoring Program for Iodine Deficiency Disorders” and the “Investigation Plan of Iodine Nutrition for Major Population in Henan Province” To carry out monitoring of iodized salt, thyroid monitoring of children aged 8 to 10 and iodine nutrition monitoring of key populations. The results showed that the qualified rates of iodized salt of residents in Xuchang City from 2013 to 2015 were 92.37%, 87.09% and 94.17%, respectively. The eating rates of qualified iodized salt were 90.17%, 85.83% and 91.50% Median and goiter rate ranged from 143.5 to 218.2μg / L and 0% to 1.08%, respectively. The median urinary iodine of lactating women and infants aged 0 ~ 2 years were both above 100μg / L. The median urinary iodine 150 ~ 249μg / L; the median of urinary iodine of newly born women of reproductive age was 100 ~ 199μg / L. Prompted iodine nutrition Xuchang crowd at an appropriate level, the current concentration of iodized salt to meet the needs of most populations of iodine nutrition, but there are still non-iodized salt and unqualified iodized salt.
