2015-2017年仁寿县重点人群尿碘水平调查分析

Monitoring on the Level of Urine Iodine Among Focus Groups in Renshou County From 2015 to 2017

目的了解仁寿县5类重点人群的碘营养水平,为碘缺乏病防治制定的策略和措施提供科学依据。方法根据《四川省重点人群尿碘监测方案》,于2015-2017年分别抽取哺乳妇女、婴幼儿、40岁以下育龄妇女、孕妇和8~10岁学龄儿童等5类重点人群,其中2015-2016年按照《尿中碘的砷铈催化分光光度测定方法》(WS/T 107-2006)进行检测,2017年按照《尿中碘第一部分:砷铈催化分光光度法》(WS/T 107.1-2016)进行检测。结果8~10岁学龄儿童尿碘中位数为104.9μg/L,低于100μg/L的比例占29.7%;哺乳期妇女尿碘中位数为117.9μg/L,低于100μg/L的比例占40.7%;40岁以下育龄妇女尿碘中位数为118.4μg/L,低于100μg/L的比例占44.7%;孕妇尿碘中位数为114.4μg/L,低于150μg/L的比例占61%;婴幼儿尿碘中位数为69.8μg/L,低于100μg/L的比例占59.3%。结论仁寿县5类重点人群中碘营养水平不足均占有相当水平,其中孕妇和儿童碘营养水平不稳定。应坚持重点人群尿碘水平的持续监测,同时开展健康教育与健康促进,提高居民自我保护意识,认识到科学补碘的重要性。

Objective To understand the iodine nutrition level of five key groups in Renshou county,and to provide scientific basis for the strategies and measures of the prevention and treatment of IDD.Methods According to the"Monitoring Program of Urinary Iodine in Key Population of Sichuan Province",from 2015 to 2017,about 5 types of key population were selected,such as school-age children from 8 to 10 year old,breastfeeding women,women of child-bearing age under 40,pregnant women and infants.From 2015-2016,the detection was taken according to the"urine iodine of arsenic cerium catalytic spectrophotometry method"(WS/T 107-2006),in 2017,detection was taken in accordance with the"urine iodine in the first part:arsenic cerium catalytic spectrophotometry"(WS/T 107.1 2016).Results the median of urinary iodine among children aged 8-10 years old was 104.9μg/L,and about 29.7%of them were less than 100μg/L.The median amount of urinary iodine of lactating women was 117.9μg/L,accounting for 40.7%of them were below 100μg/L.The median of urinary iodine among the women under 40 years old was 118.4μg/L,and 44.7%of them were under 100μg/L.The median value of urine iodine in pregnant women was 114.4μg/L,and 61%of them were below 150μg/L.The median of urine iodine in infants was 69.8μg/L,and 59.3%of them were below 100μg/L.Conclusion The iodine nutrition level of the 5 key groups in Renshou county is low,among the pregnant women and children their iodine nutrition level are unstable.We should insist on the continuous monitoring of urinary iodine levels in key populations,carry out healthy education and health promotion at the same time,and we should improve residents’self-protection awareness,to make them recognize the importance of scientific iodine supplementation.
