2016-2018年山东省日照市碘缺乏病监测结果分析

Analysis of surveillance data of iodine deficiency disorders in Rizhao City of Shandong Province from 2016 to 2018

目的分析2016-2018年山东省日照市居民的碘缺乏病监测结果。方法自山东省日照市疾病预防控制中心收集2016-2018年山东省日照市居民的碘缺乏病监测资料,分析内容包括2017年度日照市居民饮用水碘含量;2016-2018年8~10岁儿童、孕妇家中食用盐碘含量、尿碘水平,以及8~10岁儿童甲状腺容积。结果2017年在日照市共采集饮用水水样431份,水碘中位数为4.8μg/L。2016-2018年,日照市儿童及孕妇家中食用盐非碘盐率分别为11.09%(153/1380)、19.07%(302/1584)、6.92%(90/1301),合格碘盐食用率分别为80.94%(1117/1380)、65.03%(1030/1584)、84.63%(1101/1301),其中2017年非碘盐率最高(χ2=75.38,P<0.05),而合格碘盐食用率最低(χ2=56.52,P<0.05);检测8~10岁儿童尿样分别为829、891、881份,尿碘中位数分别为195.8、243.0、164.8μg/L;检测孕妇尿样分别为396、381、420份,尿碘中位数分别为161.5、148.3、105.2μg/L;8~10岁儿童甲状腺肿大率分别为1.50%(13/866)、0.89%(8/901)、1.25%(11/881),年度间比较差异无统计学意义(χ2=1.41,P>0.05)。结论日照市属环境缺碘地区,当地居民碘营养总体上处于适宜水平,但孕妇近年呈碘不足状态,是科学补碘措施所需关注的重点。

Objective To analyze the monitoring results of iodine deficiency disorders among residents in Rizhao City,Shandong Province,from 2016 to 2018.Methods Information of monitoring data on iodine deficiency disorders of residents of Rizhao City,Shandong Province from 2016 to 2018 was collected from the Center for Disease Control and Prevention of Rizhao City,Shandong Province.The analysis carried out included iodine content of drinking water for residents of Rizhao City in 2017;iodine contents of salt in the home of 8-10 years of children,pregnant women;urine iodine levels of 8-10 years of children,pregnant women;and thyroid volume of 8-10 years of children from 2016 to 2018.Results A total of 431 drinking water samples were collected in Rizhao City in 2017,the median of iodine in water was 4.8μg/L.In 2016-2018,the rate of non-iodized edible salt in the homes of children and pregnant women in Rizhao City were 11.09%(153/1380),19.07%(302/1584)and 6.92%(90/1301);the consumption rate of qualified iodized salt were 80.94%(1117/1380),65.03%(1030/1584)and 84.63%(1101/1301),respectively.Of these,the highest rate of non-iodized edible salt was in 2017(χ2=75.38,P<0.05),and with the lowest consumption rate of qualified iodized salt(χ2=56.52,P<0.05).Totally 829,891 and 881 urine samples were tested for 8-10 years of children,and the medians of urine iodine were 195.8,243.0 and 164.8μg/L,respectively.Totally 396,381 and 420 urine samples were tested for pregnant women,and the medians of urine iodine were 161.5,148.3 and 105.2μg/L,respectively.The rates of goiter in 8-10 years of children were 1.50%(13/866),0.89%(8/901)and 1.25%(11/881),respectively,and the difference between years was not statistically significant(χ2=1.41,P>0.05).Conclusions Rizhao City is an area of environmental iodine deficiency,local residents iodine nutrition in general is at an appropriate level.However,pregnant women show iodine deficiency in recent years,which will be the focus of scientific iodine supplementation measures.
