摘要
目的分析深圳市光明新区2010—2012年碘缺乏病监测结果，了解该地区碘缺乏病防控现况。方法根据《全国碘盐监测方案》，于2010、2012年在深圳市光明新区抽取2个街道办事处，每个街道办事处抽取4个居委会，每个居委会抽取15户居民食用盐。2011年在该区抽取5所小学，每所小学抽取20名8—10岁儿童，采集尿样；2012年采集该区所有自来水厂的水源水和末梢水各1份。盐碘测定采用直接滴定法；尿碘检测采用砷铈催化分光光度测定方法，水碘检测采用生活饮用水硫酸铈催化分光光度测定方法。结果2010、2012年盐碘含量分别为27．13、21．23mg／kg，居民合格碘盐食用率分别是93．33％（112／120）、90．00％（108／120）；2011年8～10岁儿童尿碘中位数为208．19μg／L；2012年水碘中位数为31．60μg／L。结论该地区为非高碘地区，近年来合格碘盐食用率符合国家标准，儿童碘营养状况良好，提示该地区除供应碘盐外不需再额外强化补碘，但仍需完善相关监测。
Objective To know the current situation of prevention and control of iodine deficiency disorders in Guangming District of Shenzhen through analyzing related monitoring indicators from 2010 - 2012. Methods According to the ＂National Iodized Salt Monitoring Program＂, in Guangrning District of Shenzhen, 2 Street Offices were chosen, then 4 Neighborhood Committees were chosen in each Street Office randomly, 15 household salt samples were selected randomly in each Neighborhood Committee; 5 primary schools were chosen in this district, and 20 urine samples were selected from 8 - 10 years old children in each school in 2011, one source water and one tap water sample were collected of all the water supply companies in this district in 2012. Salt iodine was determined by direct titration method; urinary iodine was determined by As3- - Ce4＋ catalytic spectrophotometry method; water iodine was determined by sulfate Ce catalytic spectrophotometry of drinking water standard test method. Results Salt iodine were 27.13 and 21.23 mg/kg in 2010 and 2012, respectively. The rates of qualified iodized salt in 2010 and 2012 were 93.33% （112/120） and 90.00% （i08/120）, respectively. The median concentration of urinary iodine of 8 - 10 years old children in 2011 was 208.19 Ixg/L. The median concentration of water iodine in 2012 was 31.60 Ixg/L. Conclusions The district isn＇t an iodine excess. The rates of qualified iodized salt in resent years are in line with national standards. There is no iodine deficiency in children and additional supplementation of iodine is not necessary. But relevant monitoring still needs to be improved.
