目的掌握珠海市人群碘营养状况,为制定碘缺乏病防制策略提供依据。方法以行政区为单位,采用“东、西、南、北、中”5方位抽样方法,随机抽取8—10岁儿童尿样及其家庭食用盐样,同时随机抽取居民生活饮用水样,检测尿碘、盐碘和水碘。结果珠海市8—10岁儿童尿碘中位数216.85μg/L,居民生活饮用水碘中位数6.65μg/L,居民食用盐碘中位数31.19μg/kg。结论珠海市居民碘营养状态略超过适宜量,处于可接受水平,当前的食盐碘强化浓度有向下微调的空间,但仍需坚持实施食盐碘强化策略。
Objective To grasp status of iodine nutrition among resident in Zhuhai, so as to provide scientific basis for prevention and control of iodine deficiency disorders. Methods Multiple - stage sampling concerning geographical positions was conducted and children of 8 - 10 years old were randomly selected with urine and edible salt; drinking water was sampled as well. Iodine concentration was tested from urine, edible salt and drinking water. Results Median urinary iodine of children aged 8 - 10 was 216. 85μg/L, 6. 65μg/L in drinking water and 3!. 19 μg/kg in edible salt. Conclusions Iodine nutrition level of residents in Zhuhai exceeded slightly the upper limit of adequate range, but is still within acceptable range; strategies of iodine fortification in edible salt need to be carried out continuously.
