目的了解威海市各区县妊娠妇女碘营养情况和尿碘水平,为指导该市妊娠妇女科学补碘提供依据。方法 2011-2013年随机抽取威海市各区县608名妊娠期妇女尿样进行尿碘值检测,并进行膳食碘营养问卷调查;根据《山东省〈全国碘盐监测方案〉实施细则(修订)》和《山东省碘盐监测质量控制实施方案》的要求开展居民户盐碘检测。结果 2011-2013年妊娠妇女尿碘中位数分别为170.40、160.85和157.40μg/L;3年来尿碘值<150μg/L的占总调查人数的45.06%,150~249μg/L占28.62%,250~499μg/L占19.74%,≥500μg/L占6.58%。2011-2013年盐碘中位数分别为28.6、29.3、23.4 mg/kg,威海市各区县碘盐覆盖率均达到94%以上。结论威海市各县区碘盐供应充足,妊娠妇女碘营养情况良好,但部分妊娠妇女存在严重碘缺乏或摄入过量的风险,提示应加强妊娠妇女尿碘水平监测,并指导妊娠妇女科学补碘。
Objective To understand the iodine nutrition and urinary iodine levels of pregnant women in all districts and counties in Weihai City and provide the basis for guiding scientific iodine supplementation in pregnant women in this city. Methods Urine iodine value was measured in 608 pregnant women in each district of Weihai from 2011 to 2013. The urine iodine value was measured. According to the “Implementation Rules of National Iodized Salt Surveillance Program in Shandong Province (Revised)” and “Shandong Province, iodized salt monitoring quality control implementation plan” requirements to carry out salt iodine detection. Results The median urinary iodine of pregnant women in 2011-2013 were 170.40, 160.85 and 157.40μg / L, respectively. The urinary iodine value of <150μg / L in three years was 45.06% of the total number of patients and 150 ~ 249μg / L was 28.62% 250 ~ 499μg / L accounted for 19.74%, ≥ 500μg / L accounted for 6.58%. The median salt-iodine concentrations in 2011-2013 were 28.6, 29.3 and 23.4 mg / kg, respectively. The coverage of iodized salt in all districts and counties in Weihai reached over 94%. Conclusion The supply of iodized salt in all counties of Weihai is adequate. The iodine nutrition of pregnant women is good. However, some pregnant women have a serious risk of iodine deficiency or overdose, suggesting that pregnant women should be monitored for urinary iodine level and to guide pregnant women in iodine supplementation .
