摘要
目的:了解陕西省8~10岁学龄儿童碘营养水平。方法:2017 - 2020年在陕西省所辖县(市、区),按东、西、南、北、中5个方位各抽取1个乡镇(街道),每个乡镇(街道)抽取1所小学,每所小学抽取42名8~10岁非寄宿学龄儿童(年龄均衡、男女各半)作为调查对象。采集儿童1次随机尿样,采用砷铈催化分光光度法检测尿碘。结果:2017 - 2020年共检测儿童尿样91 766份,尿碘中位数为221.7 μg/L。尿碘< 100 μg/L的占10.4%(9 554/91 766),100~< 200 μg/L的占32.3%(29 602/91 766),200~< 300 μg/L的占30.6%(28 065/91 766),≥300 μg/L的占26.7%(24 545/91 766)。各年份儿童尿碘中位数分别为228.5、218.0、211.7、230.1 μg/L,年份间比较差异有统计学意义( H = 278.66, P < 0.001)。 结论:2017 - 2020年陕西省8~10岁学龄儿童碘营养总体处于超过适宜量水平。
Objective To learn about the iodine nutrition level of school-age children aged 8-10 in Shaanxi Province.Methods From 2017 to 2020,in counties(cities,districts)under the jurisdiction of Shaanxi Province,one township(street)was selected from five directions:East,West,South,North and Middle,one primary school was selected from each township(street),and 42 non-boarding school-age children aged 8-10(age balanced,half male and half female)were selected from each primary school.Random urine samples of children were collected once,and urinary iodine was detected by arsenic-cerium catalytic spectrophotometry.Results A total of 91766 children's urine samples were tested from 2017 to 2020,and the median urinary iodine was 221.7μg/L.Urinary iodine<100μg/L accounted for 10.4%(9554/91766),100-<200μg/L accounted for 32.3%(29602/91766),200-<300μg/L accounted for 30.6%(28065/91766),and≥300μg/L accounted for 26.7%(24545/91766).The median of children's urinary iodine in each year was 228.5,218.0,211.7,and 230.1μg/L,respectively,the difference between years was statistically significant(H=278.66,P<0.001).Conclusion From 2017 to 2020,the iodine nutrition of school-age children aged 8-10 in Shaanxi Province is generally in an ultra-suitable state.
