摘　　要：目的了解2016-2018年盐城市盐都区碘缺乏病监测结果,调查重点人群碘营养状况,为盐城市盐都区制定及调整干预措施提供科学依据。方法在盐城市盐都区开展重点人群碘营养监测,检查8~10岁儿童、孕妇随机尿样尿碘浓度、家中盐样盐碘浓度,同时对其所在乡镇农村水厂监测点进行水碘监测。结果2016-2018年8~10岁儿童盐碘含量平均值分别为22.7、22.2、20.8 mg/kg,孕妇盐碘含量平均值分别为22.0、21.8、20.5 mg/kg。8~10岁儿童非碘盐率分别为4.0%、4.5%、5.5%,孕妇非碘盐率分别为6.0%、7.0%、8.0%。2016-2018年水碘含量平均值分别为7.3、7.6、13.1μg/L。各年份尿碘中位数结果8~10岁儿童分别为209.7、175.8、165.6μg/L;孕妇分别为169.8、152.2、128.4μg/L;2016-2018年儿童和孕妇尿碘值差异均有统计学意义(均P<0.05),2017和2018年孕妇尿碘值<150μg/L的构成比均高于2016年。结论盐城市盐都区外环境碘含量不高,有一定比例的非碘盐持续存在,孕妇存在碘缺乏风险,应坚持全民食盐加碘策略。Objective To understand the monitoring results of iodine deficiency disorders(IDD)in Yandu District of Yancheng City from 2016-2018,investigate the iodine nutrition status of key population,and provide scientific basis for Yandu District of Yancheng City to formulate and adjust intervention measures.Methods The monitoring of iodine nutrition in key population was carried out,to detect the urinary iodine concentration in random urine sample from children aged 8-10 years old and pregnant women,iodine content in salt,and water iodine monitoring was implemented in country water works.Results From 2016-2018,the average salt iodine content of 8~10 years old children was 22.7,22.2 and 20.8 mg/kg,respectively,and that of pregnant women was 22.0,21.8 and 20.5 mg/kg,respectively.The rate of non-iodized salt for children aged 8-10 years old was 4.0%,4.5%and 5.5%,and that for pregnant women was 6.0%,7.0%and 8.0%,respectively.From 2016-2018,average water iodine content was 7.3,7.6 and 13.1μg/L,respectively.The median content of urinary iodine in children aged 8-10 years old was 209.7,175.8 and 165.6μg/L,that in pregnant women was 169.8,152.2 and 128.4μg/L,respectively.There were statistically significant differences in urinary iodine of children and pregnant women from 2016-2018(all P<0.05),and the proportion of pregnant women with urinary iodine less than 150μg/L in 2017 and 2018 was higher than that in 2016.Conclusion The iodine content of the external environment in Yandu District of Yancheng city is not high,a certain proportion of non-iodized salt persists,and pregnant women are at risk of iodine deficiency.It is necessary to stick to the strategy of universal salt iodization.
