目的了解淄博市水源性高碘地区孕妇等5类重点人群的碘营养状况以及不同人群之间是否存在差异。方法随机抽取高青县东、西、南、北、中5个个方位的的5个乡镇,采集居民户食用盐和水样进行检测;采集孕妇等5类重点人群的尿样进行尿碘检测,并对8~10岁儿童进行甲状腺B超检查。结果 2015年共采集居民户盐300份,均为无碘盐,无碘盐率为100%;采集水样52份,中位数为225.20μg/L;采集8~10岁儿童、孕妇、哺乳期妇女、婴幼儿和育龄妇女5类重点人群尿样455份,尿碘中位数分别为392.20、168.90、164.80、238.30和375.85μg/L,不同人群尿碘浓度差异有统计学意义(F=6.047,P<0.001=;8~10岁儿童甲肿率为52.71%。结论 2015年高青县水碘中位数显示仍为高碘地区,8~10岁儿童和育龄妇女尿碘水平处于碘过量状态,孕妇、哺乳期妇女和婴幼儿碘营养处于适宜状态,8~10岁儿童甲状腺肿大率处于较高发病水平,重点人群受高碘危害比较严重,应当加强高碘地区不同人群的碘营养状况监测及指导;儿童的尿碘水平不能完全代表孕妇等重点人群的的碘营养状况,应建立孕妇等重点人群自身的碘营养状况监测标准。
Objective To understand the status of iodine nutrition in five kinds of key population such as pregnant women with high iodine level in Zibo City and whether there are any differences among different groups. Methods Five villages and towns in the east, west, south, north and south of Gaoqing County were randomly selected to detect the consumption of salt and water samples of residents. Urine samples from 5 key groups such as pregnant women were collected to detect urinary iodine , And 8 to 10-year-old children with thyroid ultrasound. Results A total of 300 household salt were collected in 2015, both of which were iodine-free salt and no iodized salt rate of 100%. 52 water samples were collected with a median of 225.20 μg / L. Collecting children aged 8 to 10, pregnant women, 455 urine samples of five kinds of key population of women, infants and women of childbearing age, urinary iodine median were 392.20,168.90,164.80,238.30 and 375.85μg / L respectively, the urinary iodine concentration in different groups had significant difference (F = 6.047, P <0.001 =. The rate of goiter among children aged 8-10 years was 52.71% .Conclusion The median of iodine in water remains high iodine in Gaoqing in 2015. The level of urinary iodine in children aged 8-10 years and women of childbearing age is in iodine Excessive status, pregnant women, lactating women and infants and young children iodine nutrition in the right state, children aged 8 to 10 goiter prevalence rate at a high level of disease, the key population is more severely affected by high-iodine, iodine should be strengthened in different populations of iodine Nutritional status monitoring and guidance; children’s urinary iodine levels can not fully represent the iodine nutrition status of pregnant women and other key populations should establish their own iodine nutrition monitoring standards for pregnant women and other key populations.
