目的:了解顺义区学龄儿童碘营养状况,为碘缺乏病防治提供科学依据。方法:对2006~2008年顺义区1024名8~10岁儿童尿碘监测结果进行分析。结果:2006~2008年学龄儿童尿碘中位数分别为213.0、238.3和168.1μg/L,3年来未检出尿碘<20μg/L的样本,尿碘<50μg/L的样本占总样本的1.2%;3个年龄组、男性和女性儿童尿碘中位数均高于200μg/L;个别学校儿童尿碘<100μg/L的样本占监测样本总数的42%。结论:顺义区学龄儿童碘营养状况良好,但碘营养水平有高于适宜量的趋势,同时个别地区学龄儿童存在碘缺乏的风险。提示应加强监测,对不同碘营养状况地区的儿童补碘实施分类指导。
Objective: To understand the iodine nutrition status of school-age children in Shunyi district and to provide a scientific basis for the prevention and treatment of iodine deficiency disorders. Methods: The urinary iodine monitoring results of 1024 children aged 8-10 years in Shunyi District from 2006 to 2008 were analyzed. Results: The urinary iodine median of school-age children from 2006 to 2008 were 213.0, 238.3 and 168.1 μg / L, respectively. Urinary iodine <20 μg / L was not detected in 3 years, urinary iodine <50 μg / L accounted for 1.2%. The median urinary iodine of children and adolescents in both age groups was higher than 200μg / L in three age groups. The average number of urine iodine <100μg / L in some school children accounted for 42% of the total number of monitoring samples. Conclusion: The iodine nutrition of school-age children in Shunyi District is good, but the iodine nutrition level is higher than the suitable amount. At the same time, the school-age children in some areas have the risk of iodine deficiency. It is suggested that monitoring should be strengthened to guide the classification of iodine in children in different iodine nutrition areas.
