目的掌握人群碘营养状况,为适时采取针对性防治措施和科学调整干预策略提供依据。方法根据《全国碘缺乏病监测方案》采样监测,采用WS/T 107—2006砷铈催化分光光度测定法检测尿碘浓度。结果低碘地区8岁~10岁学龄儿童尿碘中位数为260.2μg/L,高碘地区8岁~10岁学龄儿童尿碘中位数为778.2μg/L;低碘地区18岁~40岁孕妇尿碘中位数为195.8μg/L,高碘地区18岁~40岁孕妇尿碘中位数为687.2μg/L。结论低碘地区8岁~10岁学龄儿童碘营养状况为超过适宜量,18岁~40岁孕妇碘营养适宜,总体情况较好,建议适当降低食盐加碘量。高碘地区8岁~10岁学龄儿童及18岁~40岁孕妇碘营养状况均为过量,建议改水降碘,减少膳食摄碘量,降低碘营养相关疾病的发生风险。
Objective To understand the status of iodine nutrition in the population and provide evidences for timely taking targeted prevention and treatment measures and adjusting intervention strategies scientifically. Methods According to the “National Iodine Deficiency Disease Surveillance Program” sampling and monitoring, urinary iodine concentration was determined by arsenic and cerium catalytic spectrophotometry of WS / T 107-2006. Results The median urinary iodine of school-age children aged 8 to 10 years in the low iodine area was 260.2 μg / L, the median urinary iodine of school-age children aged 8 to 10 years in the high iodine area was 778.2 μg / L, while the low iodine area was 18 to 40 The median urinary iodine of pregnant women was 195.8μg / L and the median urinary iodine of pregnant women aged 18-40 years in high iodine area was 687.2μg / L. Conclusion Iodine nutritional status of school-age children aged 8 to 10 years in low iodine area is more than adequate. Iodine nutrition is suitable for pregnant women aged 18-40 years old. The overall situation is good, and it is recommended to reduce the amount of iodized salt properly. High iodine areas of 8-year-old school-age children aged 10 and 18 to 40-year-old pregnant women iodine nutritional status are overdose, it is recommended water and iodine reduction, reduce iodine intake of meals and reduce the risk of iodine nutrition-related diseases.
