摘要
目的了解广州市2012年下调盐碘浓度后广州市居民碘营养状况,评价盐碘新标准实施后对居民健康的影响。方法按照国家《碘缺乏病监测方案》要求对广州市居民进行碘盐和碘营养监测。结果 2011年盐碘浓度下调前,盐碘均值为30.9mg/kg,8~10岁儿童和孕妇的尿碘中位数分别为199.0μg/L、154.3μg/L;2012年盐碘浓度下调后,盐碘均值为27.3mg/kg,成人和孕妇的尿碘中位数分别为166.0μg/L、137.0μg/L。结论盐碘浓度下调后,普通成人的碘营养水平更趋合理,达到了下调盐碘浓度的目标,认为目前实行的盐碘标准是适合广州市普通人群的碘营养状况,但孕妇碘营养水平出现偏低,可能对孕妇和胎儿的健康造成影响,建议盐业部门为孕妇生产盐碘均值为30mg/kg的专用加碘盐。
Objective To understand the iodine nutritional status of residents in Guangzhou after down-regulation of iodine content in table salt in 2012 and to assess the effect on the health of the residents.Methods The iodine content in table salt and and iodine nutrition in residents of Guangzhou city were monitored according to National Iodine Deficiency Disorders（IDD）Monitoring Program.Results Before down-regulation of iodine content the average iodine in table salt was 30.9mg/kg.Median urine iodine content in children aged 8-10 years and pregnant woman were 199.0μg/L and 154.3μg/L respectively.After down-regulation of iodine content in 2012,the average iodine content were 27.3mg/kg in residents and median urine iodine content in children aged 8-10 years and pregnant woman were 166.0μg/L,137.0μg/L respectively.Conclusions The iodine nutrition in residents of Guangzhou is more reasonable after down-regulation of iodine content in salt to have attained the goal of down-regulation of iodine content in table salt.But the iodine content is a little lower than needed by the pregnant women and that might affect the health of the mother and the fetus.Iodine nutritional level of adults had trended towards reasonable and reached to the objective of adjusting down salt-iodine density.The salt-iodine standards which are put into practice now suit general iodine nutrition condition of Guangzhou citizens.But the lack of iodine nutrition for pregnant women may do harm to embryos and pregnant women themselves.The iodine content of 30mg/kg is recommended for pregnant wmen
