信阳市重点人群碘营养监测

目的了解现行碘盐水平下,信阳市5种重点人群碘营养状况,为采取防治策略和方式提供依据。方法在农村和城市选择调查点,对新婚妇女、孕妇、哺乳期妇女、0～2岁婴幼儿和8～10岁学生,采用一次性点状调查。结果共检测新婚妇女、孕妇、哺乳期妇女、0～2岁婴幼儿和8～10岁学生这5类人群的尿碘1 016份,5种人群尿碘中位数均达到100μg/L以上,由高到低依次为新婚妇女>哺乳期妇女>孕妇>婴幼儿>学生,其中哺乳期妇女、孕妇、婴幼儿、学生处于适宜水平,新婚妇女高于适宜量。5类人群尿碘<100μg/L的比例分别为13.37%、15.11%、13.1%、23.4%、20.08%,即婴幼儿和学生相对较高。结论信阳市5类人群尿碘存在明显的人群差别。现行的食盐加碘量能够满足信阳市5类人群的碘营养需求,但新婚妇女的碘营养水平有偏高的趋势,说明信阳市居民的盐含碘量有下调的空间,同时5种人群中仍有17.52%的人尿碘值<100μg/L,提示下调时要充分考虑人群差别。

Iodine nutritive surveillance of typical population in Xinyang city

Objective To find out present status of iodine nutrition among typical population eating salt with certain iodine concentration in xinyang,and to provide the basis for formulating prevention and control strategies.Methods Two survey spots were selected separately in urban and rural areas,newly married women,pregnant women,lactating women,babies and infants,and students,were carried out using cross-sectional survey method.Results A total of 1 016 urine samples from newly married women,pregnant women,lactating women,babies and infants,and students were examined.The median of iodine level in the urine of 5 different populations were all over 100 μg/L,from high to low in the order were newly married women,lactating women,pregnant women,babies and infants,students.The level of urinary iodine of lactating women,pregnant women,babies and infants,students were appropriate,newly married women was higher than appropriate.The proportion of less than 100 μg/L of urinary iodine of the 5 kinds special groups were 13.37%,15.11%,13.1%,23.4%,20.08%,respectively,while the urinary iodine of the babies and infants,and students were relatively high.Conclusions The urinary iodine of the 5 special groups in Xinyang residents had significant differences among those populations.Current iodized salt is sufficient to ensure iodine nutrition needs for the 5 special groups.But newly married women have higher levels of iodine nutrition,indicating that the salt iodine concentration of Xinyang residents have cut space,while the 5 kinds special groups there are 17.52 % of less than 100 μg/L of urinary iodine,that full consideration of the 5 special groups differences should be taken.
