摘要
目的对7年监测工作进行评估,分析新碘盐政策调整对合肥市学龄儿童碘营养的影响,为科学调整干预策略提供依据。方法按照《安徽省碘缺乏病监测方案》对合肥市原7县（区）学龄儿童进行甲状腺触诊和尿碘水平检测,并对辖区居民户食用盐进行盐碘含量检测。结果 2008-2014年合肥市原7县（区）居民户食用盐碘中位数为26.8 mg/kg,学龄儿童总甲状腺肿大率为0.76%,尿碘中位数为292μg/L。新碘盐政策调整前后,居民户盐碘水平分别为28.4 mg/kg和24.1 mg/kg,差异有统计学意义（Z=-55.064,P〈0.001）;学龄儿童甲状腺肿大率分别为0.84%和0.64%,差异无统计学意义（χ^2=1.236,P=0.266）;学龄儿童尿碘中位数分别为334.00μg/L和250.60μg/L,儿童尿碘值和尿碘频数分布差异亦有统计学意义（均有P〈0.05）。结论安徽省新碘盐政策实施后,学龄儿童尿碘水平均有所下降且尿碘逐步趋向适宜水平,应继续贯彻落实新碘盐政策。
Objective To assess the effect of the new policy about iodine salt on the nutritional status of preschool children by urinary iodine monitoring fom the year of 2008 to 2014.Methods According to the Anhui Iodine Deficiency Disorder Control Monitoring Program,the palpation of thyroid and the determination of urinary iodine were done on preschool children in Hefei.Additionally,the level of iodine in salt was also tested.Results From 2008 to 2014,the median salt iodine,the total goiter rate and the median urine iodine of preschool children in Hefei City were 26.8 mg / kg,0.76%and 292 μg / L,respectively.The median salt iodine were 28.4 mg / kg,while it was 24.1 mg / kg after the adjustment,and there was a significant differences of iodine salt level between these two years（ Z =- 55.064,P〈 0.001）; The goiter rates of preschool children were 0.84% and 0.64%,and there were no significant differences（χ~2= 1.236,P = 0.266）.The median urine iodine were 334.00 μg / L and 250.60 μg / L between those two periods.The distribution of the urine iodine value and the urine iodine frequency were also significantly different（ all P 〈0.05）.Conclusions It is suggested that the urinary iodine level would decrease with the implementation of new policy regarding iodine salt.The new policy should continue to be implemented under the urinary iodine monitoring.
