Introduction: Iodine is an essential micronutrient and its deficiency can severely impact children’s development. In 2012, the Thyroid Study Group of the Portuguese Society of Endocrinology, Diabetes and Metabolism discovered that the median urinary iodine concentration (mUIC) level in schoolchildren of São Miguel was far too low at 70.9 μg/L. In response, the government implemented a salt iodization program to help normalize levels. This investigation evaluated the efficacy of such an approach. Methods: Urinary iodine concentration (UIC) was evaluated in 362 schoolchildren from São Miguel using the fast colorimetric method. Results: mUIC was 106.7 μg/L, significantly higher than that observed in 2012 (p #x3c; 0.001). Over half (55.5%) of the schoolchildren had a UIC #x3e;100 μg/L versus 23.0% in 2012 (p #x3c; 0.001). 9.4% of schoolchildren had a UIC #x3c;50 μg/L, significantly lower than the 30.6% reported in 2012 (p #x3c; 0.001). Discussion/Conclusion: Five years after the implementation of the government salt iodization program, the mUIC increased from 70.9 to 106.7 μg/L. This study confirms the efficacy of the adopted measures in schoolchildren population.

盐碘化计划对葡萄牙亚速尔群岛圣米格尔岛学童碘状况和摄入量的影响

简介：碘是一种必需的微量营养素，缺乏碘会严重影响儿童的发育。2012 年，葡萄牙内分泌、糖尿病和代谢学会甲状腺研究小组发现，圣米格尔学童的尿碘浓度中值 (mUIC) 水平太低，仅为 70.9 μg/L。作为回应，政府实施了盐碘化计划，以帮助使水平正常化。这项调查评估了这种方法的有效性。方法：使用快速比色法评估了来自圣米格尔岛的 362 名学童的尿碘浓度 (UIC)。结果： mUIC 为 106.7 μg/L，显着高于 2012 年观察到的值（ p#x3c; 0.001）。超过一半 (55.5%) 的学童 UIC #x3e；100 μg/L，而 2012 年为 23.0% ( p #x3c；0.001)。9.4% 的学童 UIC #x3c；50 μg/L，明显低于 2012 年报告的 30.6% ( p #x3c; 0.001)。讨论/结论：政府食盐加碘计划实施五年后，mUIC 从 70.9 增加到 106.7 μg/L。这项研究证实了所采取的措施对学龄儿童的有效性。
