Assessment of Iodine Deficiency in School Age Children in Nainital District, Uttarakhand State

碘缺乏病（IDD）是Uttarakhand州一个重大的公共健康问题。本研究是在Uttarakhand州Nainital地区进行，目的是评估碘缺乏病在学龄儿童中的流行。共有2269名年龄在6-12岁的儿童被纳入本研究。对所有儿童的甲状腺进行临床检查，收集了611名儿童的现场尿样，从642名儿童的家庭厨房中收集食盐样本。总甲状腺肿大比例为15.9%。不同尿碘排泄水平＜ 20, 20-49, 50-99, 100-199和200 μg/L，儿童所占比例分别为11.8, 24.9, 38.3和25.0%。平均尿碘排泄水平为125 μg/L。约57.7%的儿童摄入的食盐含碘量不低于15 ppm。本研究结果表明：人口从15.9％碘缺乏所致甲状腺肿率过渡到尿碘排泄作为足够量中位数125微克／升水平是可能的。为了实现在本地区消除碘缺乏病，进一步加强现有的碘盐质量的监测系统是必要的。

Iodine deficiency disorder (IDD) is a major public health problem in Uttarakhand. The present study was conducted in district Nainital, Uttarakhand state with an objective to assess the prevalence of IDD in school age children. A total of 2269 children in the age group of 6-12 years were included. Clinical examination of thyroid of all children was undertaken. ＂On the spot＂ urine samples were collected from 611 children. Salt samples were collected from the family kitchen for 642 children. The Total Goitre Rate (TGR) was 15.9%. The proportion of children with urinary iodine excretion levels ＜ 20, 20-49, 50-99, 100-199 and 200 μg/L and above, was nil, 11.8, 24.9, 38.3 and 25.0 percent, respectively. The median Urinary Iodine Excretion level was 125μg/L. About 57.7% of the children were consuming salt with iodine content of 15 ppm and more. Findings of the present study indicates that the population is possibly in transition phase from iodine deficient as revealed by Total Goitre Rate of 15.9% to iodine sufficient as revealed by median urinary iodine excretion level of 125 μg/L. There is a need to further strengthen the existing monitoring system for the quality of iodized salt in the district in order to achieve the elimination of IDD.
