Iodine is a key element in the synthesis of thyroid hormones. The deficiency of the secretion of them will Reduce IQ, disturbance in the psychomotor growth and shortened height. Urinary iodine is a good indicator of iodine intake status. Urinary iodine status in at-risk groups is one of the most important indicators of community status.
All 56 universities/medical faculties in Iran should determine and report median urinary iodine and its relative distribution in school children aged 8 to 10 yr, to determine the status of urine output. The sample size in each university/college is 240 students and the cluster sampling method (48 clusters in each area in 2016) and based on probability Measurement. The amount of urinary iodine was measured quantitatively by acid digestion.
The mean urinary iodine excretion was estimated at 18.61 μg/dl. The median urinary iodine concentration in 52 universities was sufficient, and the national mean of urinary iodine excretion rate was 19.3 μg/dl. The iodine status was estimated in the optimal range in 65.6% of the students and in only 4.7% in the range of moderate and severe deficits, based on the urinary iodine index.
Iodine is sufficient in most parts of the country. The implementation of the country's national program for the prevention and control of iodine deficiency disorders has made more important the quality control of the collaborative laboratories of this program than before. Moreover, it is absolutely essential to avoid excessive iodine in order to prevent possible side effects.
碘是甲状腺激素合成中的关键元素。甲状腺激素分泌不足会降低智商、干扰精神运动发育并导致身高缩短。尿碘是碘摄入状况的良好指标。高危人群的尿碘状况是社区碘状况的最重要指标之一。
伊朗所有56所大学/医学院应测定并报告8至10岁学龄儿童的尿碘中位数及其相对分布情况，以确定尿碘水平。每所大学/学院的样本量为240名学生，采用整群抽样方法（2016年每个地区48个群组）并基于概率测量。尿碘含量通过酸消化法定量测定。
尿碘平均排泄量估计为18.61μg/dl。52所大学的尿碘中位数浓度充足，全国尿碘排泄率平均值为19.3μg/dl。根据尿碘指数，65.6%的学生碘状况估计处于最佳范围，只有4.7%处于中度和重度缺乏范围。
该国大部分地区碘充足。该国碘缺乏病防治国家计划的实施使得该计划协作实验室的质量控制比以往更为重要。此外，为防止可能的副作用，避免碘过量绝对必要。
