摘　　要：目的了解唐山市在《食用盐碘含量》（GB 26878-2011）新标准执行后盐碘含量及居民尿碘水平变化情况,为完善碘缺乏病防治工作提供科学依据。方法按照《全国碘缺乏病监测方案（试行）》和《河北省碘缺乏病监测实施方案（试行）》的要求,于2011-2013年采集生产企业、批发企业、居民家中的食用盐样,碘盐检测采用直接滴定法。随机抽取2个县各100名8~10岁儿童,采用砷铈催化分光光度测定法测定其尿碘含量,检查儿童甲状腺肿大情况;随机抽取50名儿童所在村18~40岁育龄妇女,测定尿碘含量。观察新标准执行前后盐碘含量及尿碘水平的变化情况。结果与2011年生产及批发企业食用盐碘含量（29.94±3.31）mg/kg、（29.97±4.08）mg/kg）相比,2012及2013年分别为（26.16±6.43）mg/kg、（25.44±3.95）mg/kg,（25.67±5.81）mg/kg、（25.25±3.36）mg/kg,均有所降低,且差异有统计学意义（P〈0.05）。与2011年居民户食用盐碘含量中位数（28.60 mg/kg）相比,2012年（26.70 mg/kg）有所降低,但差异无统计学意义;2013年（24.53 mg/kg）进一步降低,且差异有统计学意义（P〈0.05）。2013年儿童及育龄妇女尿碘水平（220.81μg/L,193.34μg/L）与2011年（252.52μg/L,260.13μg/L）相比,均有所降低（P〈0.05）。结论唐山市食用盐碘含量符合GB 26878-2011要求;盐碘含量下调后居民尿碘水平下降,趋于适宜水平。Objective To understand the variation of salt iodine content and urine iodine concentration after the new standard of iodine content of edible salt in Tangshan city,in order to provide a scientific basis for the relevant policy to iodine deficiency disorders. Methods According to the requirements of National iodine deficiency disorders monitoring project（ trial）,and Iodine deficiency monitoring implementing project（ trial）,salt samples were collected from edible salt manufacturers,wholesalers and household from 2011 to 2013,salt samples were tested with direct titration method. 100 children aged 8 to 10 years were randomly sampled from2 counties,using arsenic cerium catalytic spectrophotometry to determine the urine iodine content,to check the rate of goiter; and urinary iodine content of 50 women of child-bearing age 18 to 40 years old were detected. To observe salt iodine concentration and urine iodine concentration before and after the new standard implementation. Results The values of salt iodine concentrations in edible salt of manufacturer and wholesalers in2012 and 2013 were（ 26. 16 ± 6. 43） mg / kg,（ 25. 44 ± 3. 95 mg） / kg,（ 25. 67 ± 5. 81） mg / kg and（ 25. 25± 3. 36） mg / kg that were all significantly declined compared with 2011 of（ 29. 94 ± 3. 31） mg / kg and（ 29. 97 ± 4. 08） mg /Kg,the differences were statistically significant（ P〈0. 05）. The medians of household salt iodine concentration in 2012 was 26. 70 mg / kg,reduced from 28. 60 mg / kg in 2011,but there is no significant statistically differences and 24. 53 mg / kg in 2013 which was reduced further,and there was significant statistically differences（ P〈0. 05）. Compared monitoring results of 2013 with that of 2011,children＇s urine iodine concentration decline significantly from 252. 52μg / L to 220. 81 μg / L,urinary iodine concentrations of women decline significantly from 260. 13μg / L to 193. 34μg / L（ P〈0. 05）. Conclusions The iodine content of edible salt of Tangshan city meet t
