摘要
目的了解现行的碘盐水平下,内蒙古部分地区重点人群的碘营养现状。方法在选取的城市和农村调查点,采用一次性点状调查方式。盐碘测定采用直接滴定法;尿碘、乳汁碘测定采用砷铈催化分光光度测定法;水碘检测采用砷铈氧化还原法。结果①触诊肿大率为6.0%,B超肿大率为4.0%;②5种人群尿碘中位数均达到了100μg/L以上,表现为婴幼儿>学龄儿童>育龄妇女>哺乳期妇女>孕妇;③城市和农村盐碘中位数分别为30.4和27.5mg/kg,碘盐覆盖率分别为97.7%和97.9%;④乳汁碘达到了100～200μg/L的适宜水平;⑤农村水中含碘量大于城市。结论目前盐碘水平可满足不同人群碘营养水平,孕妇和哺乳期妇女碘水平相对偏低,8～10岁儿童不能够完全代表其他人群碘水平。
Objective To find out present status of iodine nutrition among typi cal population eating salt with certain iodine concentration in some areas of th e Inner Mongolia Autonomous Region. Methods Two survey spots were selected separ ately in urban and rural areas, cross-sectional survey method was carried out. Iodized salt was determined by direct titration, urinary iodine was determined b y arsenic-cerium catalytic spectrophotometry, iodine in water was determined by arsenic-cerium oxidation-reduction method,and lactic iodine was determined by th e same method as urinary iodine after the sample was diluted over five times. Re sults ①The goiter rate diagnosed by palpating was 6.0 %, by B-ultrasound was 4. 0%. ②The median of iodine level in the urine of 5 different populations was all over 100 μg/L,from the highest to the lowest being that of infants, school ch ildren, women of child-bearing age, lactating women and pregnant women, respecti vely.③The median of iodine level was 30.4 and 27.5 mg/kg, the iodized salt cove rage 97.7% and 97.9%, respectively for city and village.④The lactic iodine was 100 ～ 200 μg/L,which was appropriate. ⑤Iodine in water was higher in village than in city. Conclusions Current iodine level of iodized salt is suitable for d ifferent population. Compared to others, the pregnant and lactating women have r elatively lower iodine level, and the iodine level of the children aging from 8 to 10 does not represent that of other populations perfectly.
