摘　　要：目的掌握2016-2018年上海市静安区孕妇食盐含碘量及碘营养水平,分析盐碘与碘营养的关系,为孕妇科学补碘提供依据。方法2016-2018年,在静安区14个街道(镇),采取分层随机抽样方法,每个街道(镇)抽取孕早(≤12周)、孕中(13~28周)、孕晚期(29~40周)的孕妇,采集其随机尿样测定尿碘,采集孕妇家庭盐样测定盐碘。盐碘检测采用直接滴定法,川盐及其他强化盐采用仲裁法测定,尿碘检测采用砷铈催化分光光度法测定。结果共检测751份孕妇家庭盐样。2016-2018年合格碘盐食用率分别为68.5%、69.0%和61.0%。非碘食盐率逐年上升,2018年最高为36.0%。共采集751份孕妇尿样,尿碘总体中位数为141.0μg/L,处于不足状态。2016-2018年孕妇尿碘含量中位数分别为137.3、159.6和84.0μg/L。食用碘盐者中尿碘处于适宜水平的人群所占的比例高于食用非碘盐者,但差异无统计学意义(P>0.05)。结论上海市静安区孕妇碘营养处于不足状态。应持续调查碘盐和其他途径摄入的碘对尿碘的影响,依据碘营养水平结果采取有差异的补碘措施。Objective To investigate the iodine content of table salt and iodine nutrition status of pregnant women in Jing’an District of Shanghai from 2016-2018,analyze the relationship between salt iodine and iodine nutrition,and provide the basis for scientifically iodine supplement among pregnant women.Methods From 2016-2018,a stratified random sampling method was used to select pregnant women in the first(≤12 weeks),second(13-28 weeks)and third trimester(29-40 weeks)of pregnancy in14 streets(towns)of Jing’an District.Random urine samples were collected for determination of urinary iodine,and pregnant women’s household salt samples were collected for determination of salt iodine.The iodine level in salt was determined by direct titration,and the salt samples from Sichuan and other enhanced salt samples were detected by arbitration method.Urinary iodine was determined by As-Ce catalysis spectrophotometry.Results In total,751 household salt samples of pregnant women were collected and determined.The consumption rates of qualified iodized salt were respectively 68.5%,69.0%and 61.0%from 2016-2018.The consumption rate of non-iodized salt was rising year by year,up to 36.0%in 2018.751 urine samples of pregnant women were collected and the median urinary iodine content was 141.0μg/L,which was at insufficient level.The medians of urinary iodine for pregnant women were respectively 137.3,159.6 and 84.0μg/L from 2016-2018.The proportion of people whose urine iodine was at the appropriate level in iodized salt group was higher than non-iodized salt group,but the difference was not statistically significant(P>0.05).Conclusion The iodine nutritional status of pregnant women in Jing’an District of Shanghai is at insufficient level.The effects of iodized salt and other sources of iodine intake on urinary iodine should be continuously investigated.Different iodine supplementation measures should be adopted based on the results of iodine nutrition level.
