[目的]了解珠海市8～10岁儿童碘营养状况,为制定碘缺乏病防治策略提供基础数据。[方法]以县(区)为单位,按“东、西、南、北、中”5方位抽取随机抽取5所小学;在所抽取小学各随机抽检20名8～10岁儿童尿样,用砷铈催化分光光度法检测其尿碘浓度。[结果]各监测区8～10岁儿童尿碘中位数为200.43～237.81μg/L,50μg/L以下所占比例为1%～3%。全市8～10岁儿童尿碘中位数213.05μg/L,50μg/L以下所占比例为1.67%。[结论]珠海市8～10岁儿童碘营养状态略超过适宜量,处于可接受水平。
[Objective] To understand the iodine nutrition status of children aged 8 ~ 10 years in Zhuhai and to provide basic data for the prevention and control of iodine deficiency disorders. [Method] Five primary schools were randomly selected from 5 locations of “East, West, South, North and Central” by county (district). Urine samples of 20 children aged 8-10 years were randomly selected from primary schools , With arsenic cerium catalytic spectrophotometry urinary iodine concentration. [Results] The median urinary iodine of children aged 8-10 years in each monitoring area was 200.43-237.81μg / L, and the proportion of urinary iodine was below 1% -3% under 50μg / L. The median urinary iodine in children aged 8 to 10 years in the city was 213.05 μg / L, with a proportion of 1.67% below 50 μg / L. [Conclusion] The iodine nutritional status of children aged 8 ~ 10 years in Zhuhai slightly exceeded the appropriate level and was at an acceptable level.
