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31.19 mg/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 understand the status of iodine nutrition in Zhuhai population and provide evidence for the prevention and control of iodine deficiency disorders. Methods Using the sampling method of “east, west, south, north and center” 5 directions, the urine samples of 8 ~ 10 years old children and their family edible salt samples were randomly selected from the administrative districts. At the same time, Urinary iodine, iodine and iodine were tested. Results The median urinary iodine of children aged 8 ~ 10 years in Zhuhai was 216.85μg / L, the median of drinking water of residents was 6.65μg / L, and the median of salt iodine of residents was 31.19 mg / kg. Conclusion The iodine nutrition status of residents in Zhuhai slightly exceeds the appropriate level and is at an acceptable level. There is room for downward adjustment of salt iodine concentration at present. However, it is still necessary to persist in implementing the salt iodine fortification strategy.
