摘要目的 分析广东省云浮市2009-2016年度碘营养水平,为制订碘缺乏病防治策略提供依据.方法 根据广东省地方病防治规划,2009-2016年度在云浮市进行4次碘盐含量调查、4次8～10岁儿童尿碘水平调查、2次孕妇尿碘水平调查和1次生活饮用水水碘含量调查.盐碘测定采用直接滴定法(GB/T13025.7-1999、GB/T 13025.7-2012),尿碘测定采用砷铈催化分光光度方法(WS/T 107-2006、WS/T 107.1-2016),水碘测定采用国家碘缺乏病参照实验室推荐方法.结果 2009、2011、2015、2016年度各调查1464、1464、1500、1500份盐样和500、388、1000、1000名儿童,盐碘中位数分别为30.3、28.1、24.8、24.8 mg/kg,儿童尿碘中位数分别为208.3、188.3、143.1、165.2 μg/L.2015、2016年度各调查500、500名孕妇,孕妇尿碘中位数分别为101.0、96.4 μg/L.2011-2016年度共调查1 149份生活饮用水,水碘中位数为2.8μg/L.结论 云浮市属缺碘地区,经过2012年食用盐碘含量调整,儿童碘营养处于适宜水平,但孕妇碘摄入量偏低,应对孕妇人群加强防治碘缺乏病宣教和尿碘监测.

abstractsObjective To analyze the residents' iodine nutrition level of Yunfu City in Guangdong Province from 2009 to 2016,in order to provide evidence for making prevention strategy of iodine deficiency disorders.Methods Four surveys on salt iodine levels,four surveys on urinary iodine levels of children aged 8-10 years old,two surveys on urinary iodine levels of pregnant women and one survey on iodine content in drinking water were carried out according to the prevention and control planning for endemic disease in Guangdong Province in Yunfu City from 2009 to 2016.Salt iodine was determined by direct titration (GB/T 13025.7-1999,GB/T 13025.7-2012),urinary iodine was determined by arsenic cerium catalytic spectrophotometry (WS/T 107-2006,WS/T 107.1-2016),water iodine was determined by the national iodine deficiency disease reference laboratory recommended method.Results In 2009,2011,2015 and 2016,1 464,1 464,1 500,1 500 salt samples and 500,388,1 000,1 000 children were investigated,the medians of salt iodine levels were 30.3,28.1,24.8,and 24.8 mg/kg,respectively,and the medians of children urinary iodine levels were 208.3,188.3,143.1 and 165.2 μg/L,respectively.Five hundred,five hundred pregnant women were investigated in 2015 and 2016,and the medians of pregnant women urinary iodine levels were 101.0 and 96.4 μg/L,respectively.A total of 1 149 samples of drinking water were investigated in 2011-2016,the median of water iodine was 2.8 μg/L.Conclusion Yunfu is an iodine deficiency city,after adjusting the iodine content of edible salt in 2012,iodine nutrition in children is at an appropriate level,but the iodine intake level of pregnant women is relatively lower,so prevention and treatment of iodine deficiency disorders and urinary iodine monitoring should be strengthened in pregnant women.
