2009年和2015年乐山市8岁～10岁学龄儿童尿碘监测结果分析

Analysis of monitoring results of urinary iodine of 8-10 years old school children in Leshan during 2009-2015

目的了解碘缺乏病防治2009年与2015年乐山市8岁~10岁学龄儿童尿碘水平变化,掌握重点人群碘营养状况,引导科学补碘,为碘缺乏病防治工作提供理论依据。方法收集2009年和2015年乐山市8岁~10岁学龄儿童尿碘各1 100份,对监测结果进行分析。结果 2009年尿碘中位数为203.5μg/L,均值为206.4μg/L,各区县尿碘中位数为139.9μg/L^269.6μg/L,频数分布最多为42.3%,在200μg/L^300μg/L;2015年尿碘中位数为185.0μg/L,均值为200.3μg/L,各区县尿碘中位数为133.0μg/L^233.0μg/L,频数分布最多在100μg/L^200μg/L处(40.7%)。结论乐山市8岁~10岁学龄儿童尿碘中位数2015年比2009年略有下降,但仍然在合格水平,碘营养状况良好,但尿碘中位数略高,仍需加强碘缺乏病监测工作,强化学龄儿童健康教育。

Objective To study the changes of urine iodine level of 8-10 years old school children in Leshan city during 2009-2015,master the status of iodine nutrition of key population,so as to lead the scientific iodine supplementation and provide theoretical basis for the prevention and treatment of iodine deficiency disorders. Methods 1 100 copies of monitoring data of urine iodine were respectively collected from 8-10 years old school children in Leshan city in 2009 and 2015,and the monitoring results were analyzed. Results In 2009,the median of urinary iodine was 203. 5 μg/L,the average of urine iodine was206. 4 μg/L,and the median of urine iodine in each district was within 139. 9 μg/L-269. 6 μg/L. The frequency distribution was 42. 3% within 200 μg/L-300 μg/L; the median of urinary iodine was 185. 0 μg/L in 2015,the average of urine iodine was 200. 3 μg/L,and the median of urine iodine in each district was within 133. 0 μg/L-233. 0 μg/L. The frequency distribution was 40. 7% within 100 μg/L-200 μg/L. Conclusion The median urine iodine of 8-10 years old school children in Leshan in 2015 decreased slightly than that in 2009,and the iodine nutrition status is good,but the median of urine iodine is slightly higher. The iodine deficiency disorders should be monitored in Leshan and the health education should be strengthened.
