摘要
目的 了解张家口市8～ 10岁学生尿碘监测结果,分析尿碘监测结果中的问题,为制订碘缺乏病防治策略提供依据.方法 在张家口市每个县（区）,按东、西、南、北、中5个方位各抽取1个乡（镇、街道）；在所抽取的每个乡（镇、街道）各抽取1所小学；在所抽取小学各抽检20名8～ 10岁儿童（男、女各半）尿样进行尿碘测定.结果 共检测8～ 10岁儿童尿样1700份,尿碘中位数为291.5 μg/L,＜50μg/L的占0.8％（13/1700）,50～99 μg/L的占4.9％（83/1700）,100～199μg/L的占20.5％（349/1700）,200～299 μg/L的占29.7％（504/1700）,≥300μg/L的占44.9％（764/1700）.结论 张家口市8～ 10岁儿童尿碘监测数据已达到消除碘缺乏病指标要求.但尿碘超过足够量和碘过剩情况比较严重,说明现在的加碘浓度还有下调的必要.
Objective To analyze the monitoring results of urinary iodine of students aged 8 - 10 in Zhangjiakou city,problems in monitoring results,and to provide basic information for working out control strategies of iodine deficiency disorders.Methods A township（town,street） in each country of each city（district） in Zhangjiakou was selected according to 5 positions of the east,the west,the south,the north and center,and 1 village elementary school was sampled in each chosen township,twenty students（half male and female） aged 8 - 10 were selected to collect their urine samples in each school.Urinary iodine concentration was determined by arseniccerium method.Results The median of urinary iodine of the 1700 children aged 8 - 10 was 291.5 μg/L,with 〈 50 μg/L accounted for 0.8%（13/1700）,50 ～ 99 μg/L about 4.9%（83/1700）,100 - 199 μg/L about 20.5% （349/1700）,200 - 299 μg/L about 29.7%（504/1700）,and ≥300 μg/L about 44.9%（764/1700）.Conclusions Urinary iodine has reached the elimination standard of iodine deficiency disorders in Zhangjiakou city.But the situation of more than adequate amount of urinary iodine and iodine excess is relatively serious and it is necessary to lower iodine concentration.
