Analysis on monitoring results of residents iodized salt and urinary iodine of children and adults from 2013 to 2015 in Chengyang district of Qingdao

目的探讨2013—2015年青岛市城阳区居民碘盐及儿童和成年人尿碘情况。方法按照分层随机抽样的方法,2013—2015年各抽取300份盐样进行居民户碘盐监测,各抽取100名8~10岁儿童、50名成年人尿样进行尿碘监测。结果 2013—2015年碘盐合格率、碘盐覆盖率、合格碘盐食用率、非碘盐率均达到国家碘缺乏病消除标准,盐碘中位数分别为27.00、23.30、22.12 mg/kg,逐年降低且差异有统计学意义(H=246.111,P<0.05)。2013—2015年8~10岁儿童尿碘均以100~300μg/L所占比例最大,尿碘中位数分别为238.00、214.00、202.20μg/L,逐年降低且差异有统计学意义(H=53.454,P<0.05)。2013、2015年成年人尿碘>300μg/L合计占26.00%亦逐年降低,均以100~300μg/L所占比例最大,尿碘中位数分别为197.85、195.43μg/L,不同年份尿碘中位数比较,差异无统计学意义(H=2.966,P>0.05)。结论 2013—2015年青岛市城阳区已达到国家碘缺乏病消除标准,但仍需进行人群尿碘监测,以保障碘营养处于适宜水平。

Objective To explore the monitoring results of residents iodized salt and urinary iodine of children and adults from 2013 to 2015 in Chengyang district of Qingdao. Methods According to the stratified random sampling method, 300 salt samples were collected from each household with iodized salt monitoring, extracted urine of 100 8-10 years old children and 50 adults with urinary iodine monitoring from 2013 to 2015. Results From 2013 to 2015, qualified rate of iodized salt, coverage rate, the rate of qualified iodized salt, non iodized salt rate had reached the national standard of eliminating IDD, The median salt iodine was 27.00, 23.30, 22.12 mg/kg, decreased year by year and with statistical difference （H=246.111, P〈0.05）. 8-10 years old children were 100-300μg/L urinary iodine accounted for the largest proportion from 2013 to 2015, the median urinary iodine were 238.00,214.00,202.20μg/L decreased year by year and with statistical difference （H=53.454, P〈0.05）. In 2013 and 2015, 〉300 μg/L urinary iodine adults accounted for 26.00% of total also reduced year by year, were also 100-300μg/L accounted for the largest proportion, the median urinary iodine were 197.85 and 195.43μg/L, and with no statistical difference （H=2.966, P〉0.05）. Conclusion The national standard of iodine deficienly elimination has been reached in Chengyang district of Qingdao from 2013 to 2015, but the people still should be momtored urinary iodine, and to ensure the iodine nutrition in a suitable level.
