2015-2017年无锡市儿童甲状腺B超监测结果调查分析

Investigation and analysis on monitoring results of thyroid type B ultrasonograply among the children in Wuxi City from 2015 to 2017

目的对无锡市8~10周岁儿童的甲状腺肿大情况进行B超监测分析,为合理补碘提供科学依据。方法采用容量比例概率(PPS)抽样法列出无锡市符合条件的抽样单位,按顺序编号,根据各地人口数,计算出累计人口数,用总人口数除以30得出组距,取一随机8位数除以组距,所得的余数在哪个抽样单位的累计人口数段中即为选中的第一个抽样学校,以此类推。在被抽到的每所小学中随机抽取40名8~10岁学生共1 900名为甲状腺肿大调查对象。收集2015-2017年无锡市儿童碘营养调查工作中的甲状腺B超检测数据资料,分析甲状腺肿大情况以及年龄、性别、尿碘结果等分布情况。结果 2015年该市8~10周岁儿童甲状腺肿大率为0. 2%,该市8~10周岁儿童甲状腺容积中位数为0. 92 ml,儿童尿碘水平M (P25~P75)为180. 5(117. 5~247. 8)μg/L;2016年该市8~10周岁儿童甲状腺肿大率为1. 3%,该市8~10周岁儿童甲状腺容积中位数为2. 27 ml,儿童尿碘水平M (P25~P75)为197. 0 (128. 0~286. 0)μg/L;2017年该市8~10周岁儿童甲状腺肿大率为1%,该市8~10周岁儿童甲状腺容积中位数为1. 73 ml,儿童尿碘水平M (P25~P75)为195. 2 (129. 4~273. 1)μg/L。结论 2015~2017年该市儿童甲状腺肿大率处于正常水平,在合理调整食盐碘含量的同时应加强预防碘缺乏的健康教育,明确科学补碘的重要性。

Objective B-ultrasound monitoring and analysis of goiter of children aged 8~10 years in Wuxi city was carried out to provide scientific basis for reasonable iodine supplementation.Methods Using PPS sampling method,all sampling units in the city are listed with sequential numbers,and the population numbers around are given,and the cumulative population numbers are calculated.the total population numbers are divided by 30 to get the group distance.a hundred yuan number(eight digits)is taken as the random number,and the random eight digits are divided by the group distance.the remainder obtained is the first sampling school selected in the cumulative population number segment of sampling units,and so on.Forty students aged 8 to 10 were randomly selected from each primary school to investigate goiter in 1900 children.Collecting data of thyroid b ultrasound examination in iodine nutrition survey of children in Wuxi city from 2015 to 2017,and analyzing goiter,age,sex,urine iodine results and other partial situation.Results In 2015,the goiter rate of children aged 8~10 years in this city was 0.2%;the median thyroid volume of children aged 8~10 years in this city was 0.92 ml;the urine iodine level m(p25~p75)of children was 180.5(117.5~247.8)μg/L;in 2016,the goiter rate of children aged 8~10 years in this city was1.3%;the median thyroid volume of children aged 8~10 years in this city was 2.27 ml;and the urine iodine level m(p25~p75)of children was 197.0(128.0~286.0)μg/L.Conclusion From 2015 to 2017,the goiter rate of children in this city was at the normal level.health education to prevent iodine deficiency should be strengthened and the importance of scientific iodine supplementation should be clarified while reasonably adjusting the iodine content of salt.
