【摘要】：目的了解2012—2014年浙江省玉环县8~10岁儿童尿碘水平以及食用盐碘含量状况及变化。方法采用重复横断面调查设计,于2012—2014年对浙江省玉环县儿童开展3次横断面调查,以分层整群抽样的方法选定玉环县某小学3~5年级(8~10岁)9个班(每年级3个班)所有学生,收集晨尿及家庭食用盐,检测晨尿尿碘水平及食用盐碘含量。结果 1343名学生尿碘中位数为116.0μg/L,尿碘含量50μg/L、100μg/L和≥300μg/L分别占4.8%、38.6%和3.5%,未发现儿童尿碘水平和分布的不同年份、性别和年级的统计学差异。检测食用盐1343份,盐碘中位数为0.0 mg/kg,碘盐覆盖率、碘盐合格率、合格碘盐食用率分别为22.8%、89.5%和20.4%,2012—2014年的合格碘盐食用率分别为25.1%、21.8%和14.2%,逐年降低,差异有统计学意义(χ2=20.232,P0.001)。盐碘与尿碘的平均水平及含量分布均有统计学关联,Spearman相关分析显示盐碘与尿碘呈弱正相关关联(r=0.135,P0.001)。结论 2012—2014年浙江省玉环县8~10岁儿童碘营养状况总体上是平稳、适宜和安全的,但碘盐覆盖率过低。
[Abstract]:Objective to investigate the urinary iodine level and salt iodine content in children aged 8 to 10 years from 2012 to 2014 in Yuhuan County, Zhejiang Province. Methods three cross-sectional surveys were conducted on children in Yuhuan County of Zhejiang Province from 2012 to 2014 by repeated cross-sectional survey design. A stratified cluster sampling method was used to select all students from 9 classes (3 classes per grade) in grade 3 ~ 5 (8 ~ 10 years old) in a primary school in Yuhuan County. Morning urine and household edible salt were collected and the iodine level in urine and iodine content in edible salt were measured. Results the median of urinary iodine in 1343 students was 116.0 渭 g / L, and the urinary iodine content of 50 渭 g / L and 鈮，
