目的通过对8～10岁儿童尿碘含量和甲状腺肿大率进行分析,掌握济南市儿童碘营养水平及分布状况,为制定碘缺乏病防治对策提供依据。方法在济南市8个县(市)、区采取随机抽样的方法,对8～10岁的儿童进行尿碘和甲状腺检测。结果本次调查共检测850份尿样,尿碘中位数为146.61μg/L;尿碘<20μg/L的占11.2%;尿碘在20～50μg/L之间占9.8%;尿碘在50～100μg/L之间占17.4%;尿碘在100～300μg/L之间占42.7%;尿碘>300μg/L的占18.9%。儿童甲状腺肿大率为3.16%。不同县(市)、区儿童尿碘水平差异有统计学意义(P<0.05);不同年龄、不同性别儿童尿碘水平差异无统计学意义(P>0.05)。结论济南市8～10岁儿童的碘营养水平达到国家消除碘缺乏病的标准。
Objective To analyze the urinary iodine content and goiter rate in children aged 8 ~ 10 years to understand the iodine nutrition status and distribution in children in Ji’nan, and to provide evidence for the prevention and control of iodine deficiency disorders. Methods Random sampling method was adopted in 8 counties (cities) in Jinan City to detect urinary iodine and thyroid in children aged 8 to 10 years old. Results A total of 850 urinary samples were detected in this survey. The urinary iodine median was 146.61 μg / L; urine iodine <20 μg / L accounted for 11.2%; urinary iodine accounted for 9.8% between 20 and 50 μg / L; Between 50 ~ 100μg / L accounted for 17.4%; urine iodine between 100 ~ 300μg / L accounted for 42.7%; urinary iodine> 300μg / L accounted for 18.9%. Children goiter rate was 3.16%. The urinary iodine levels of children in different counties (cities) and districts were significantly different (P <0.05). There was no significant difference in urinary iodine between children of different ages and genders (P> 0.05). Conclusion The iodine nutrition level of children aged 8 ~ 10 in Jinan reached the national standard of eliminating iodine deficiency disorders.
