摘　　要：目的 通过分析北京市怀柔区儿童碘营养水平,评价怀柔区人群碘营养状况,为科学补碘提供依据。方法 2017-2020年每年选取5个街道/乡镇,每个街道/乡镇抽取1所小学,每所小学抽取8~10岁儿童40人,采集儿童家中食用盐,收集儿童尿样,测定尿碘和盐碘。结果 2017-2020年共收集842份儿童尿样本,各年尿碘中位数分别为188、186、197和190μg/L,均在适宜范围内;2017-2020年共收集842份儿童盐样本,各年盐碘中位数分别为20.5、21.3、21.0和22.5 mg/kg,均为合格。合格碘盐食用率仅2018年达到90.09%,2017、2019和2020年均低于90%;碘盐覆盖率(χ^(2)=66.423,P<0.001)、合格碘盐食用率(χ^(2)=8.915,P=0.030);4年间差异均有统计学意义,其中2019年合格碘盐覆盖率(81.65%)未达到碘缺乏病消除判定标准,2020年合格碘盐覆盖率(92.25%)达到标准;4年间8~10岁儿童甲状腺肿大率为4.87%。结论 怀柔区2017-2020年8~10岁儿童尿碘、盐碘中位数结果处于适宜范围内,怀柔区人群的碘营养状况充足。碘盐供应需加强监管、加大对人群碘缺乏病知识的健康教育,巩固现有人群的碘营养水平。Objective To analyze the iodine nutritional status of children in Huairou district of Beijing and adjust the intervention for children’s scientific iodine supplementation in Huairou district.Methods From 2017 to 2020, five streets/towns were selected each year in Huairou district, one primary school was selected from each street/town, and 40 children aged 8 to 10 years old were selected from each primary school. Edible salt was collected from children’s homes, at the same time, the urine samples were also collected to detect urinary iodine and salt iodine values.Results From 2017 to 2020, a total of 842 urine samples were collected from children, the median urinary iodine values were 188, 186, 197 and 190μg/L for each year, which were all within the appropriate range;a total of 842 salt samples were collected from children’s homes, the median salt iodine values were 20.5, 21.3, 21.0 and 22.5 mg/kg for each year, which were all qualified. Only in 2018, the consumption rate of qualified iodized salt reached 90.09%, which was below 90% in other three years. There were significant differences in the coverage rate of iodized salt(χ^(2)=66.423, P<0.001) and the consumption rate of qualified iodized salt(χ^(2)=8.915, P=0.030) in the four years. In 2019, the coverage rate of qualified iodized salt(81.65%) did not meet the standard of iodine deficiency disorders, and in 2020, this indicator(92.25%) met the standard. The incidence rate of goiter in children aged 8 to 10 years was 4.87%.Conclusions The median of urinary iodine and salt iodine of children aged 8-10 years in Huairou district from 2017 to 2020 were within the appropriate range, and the iodine nutritional status of the population in Huairou district was adequate. It is suggested to strengthen the supervision of iodized salt supply, strengthen the health education of iodine deficiency disease knowledge, and further consolidate the iodine nutrition level of the population.
