摘要:目的 了解深圳市居民碘营养状况，评价居民碘营养状况。方法 采取整群、分层、随机抽样相结合的方法，于2013年2月至2014年12月在深圳市抽取3个不同行政区及关外居民共352人作为调查对象，采集晨尿进行尿碘水平检测。结果 检测尿碘范围为34.7~518.4μg/L，尿碘中位数为101.9μg/L；尿碘水平＜100μg/L的占50%，100~199μg/L的占14.2%，200~300μg/L的占9.4%， ＞300μg/L的占26.4%。结论 深圳地区居民碘营养状况总体处于适宜和安全水平。

Abstract: Objective To assess the current iodine nutrition levels in Shenzhen to add into the data pool for fully establishment of evidence. Methods Totally 352 cases from four areas of Shenzhen city were selected randomly with stratified cluster random sampling method. The morning urine samples were collected to determine iodine levels. Results The median urinary iodine (MUI) concentrations was 101.9μg/L with a range of 34.7～518.4μg/L in all sample. Among them, 50% were <100μg/L whilst 26.4% were >300μg/L. Conclusion The iodine status in the sample of Shenzhen adults was appropriate according to WHO requirement of MUI, though almost half of them was under the level, while a quarter is higher than that, indicating a demand for more individualized monitoring system at the time of USI continuation.
