摘要： 【摘要】 目的  了解新标准碘盐供应对芜湖市居民碘营养状况的影响，为今后调整碘盐浓度提供依据。 方法  调查2011~2014年碘盐浓度调整前后芜湖市8个县（区）儿童、孕妇碘营养状况以及芜湖市居民食用盐状况。盐碘检测采用直接滴定法，川盐及其他强化食用盐采用仲裁法（GB/T 13025.7-1999）；尿碘检测采用砷铈催化分光光度方法（WS/T 107-2006）。 结果  芜湖市2011~2014年分别采集食盐1 968份、2 280份、2 340份、2 280份；检测碘盐中位数分别为30.85mg/kg、26.79mg/kg、24.2mg/kg、23.3mg/kg；8~10岁儿童尿碘中位数分别为283.33μg/L、269.02μg/L、240.23μg/L、207.54μg/L；2012～2014年孕妇尿碘中位数分别为208.8μg/L、193.02μg/L、163.6μg/L。 结论  新标准碘盐满足了8~10岁儿童碘营养需求，但是孕妇存在碘营养不足的危险，需要加强对孕妇健康教育，提高孕妇补碘意识。

Abstract:

【Abstract】 Objective  To investigate the current iodine nutritional status in population in Wuhu City after practice of the new iodized salt concentration standard for scientific basis to accurately rectify the iodine supplementation in table salt. Methods  Iodine nutrition status and dietary intake of salt were surveyed in children and pregnant women as well as civilians in 8 counties/districts in Wuhu City from 2011 to 2014. The salt iodine concentration was measured by direct titration technique, and the chuan salt and other fortified salt were tested by the method of arbitration (GB/T 13025.7-1999). Urinary iodine was determined with arsenic-cerium catalytic spectrophotometry (WS/T 107-2006). Results  A total of 1968, 2280, 2340 and 2280 samples were respectively collected from 2011 to 2014, and corresponding median of salt iodine was 30.85mg/kg, 26.79mg/kg, 24.2mg/kg and 23.3mg/kg. The median of urinary iodine was 283.33μg/L，269.02μg/L，240.23μg/L and 207.54μg/L, respectively for children aged between 8 and 10 years, and 208.8μg/L, 193.02μg/L and 63.6μg/L for pregnant women during 2012 and 2014. Conclusion  The new standard of iodized salt concentration may satisfy the essential iodine nutrition for children aged 8~10 years, yet iodine deficiency may be present in pregnant women, who are required to give health education to raise their awareness of individual iodine supplement.
