机体因缺碘而导致的一系列障碍被统称为碘缺乏病(Iodine defic iency d iso rders,IDD),中国是受IDD严重威胁的国家之一。缺碘可引起脑发育障碍而导致轻度智力落后,包括精神运动发育障碍在内的轻度神经、精神损害以及亚临床甲低,成为严重影响人口素质、阻碍发展的社会问题。随着IDD的被控制,对各种人群尤其是对中小学生碘营养状况的监测已成为主要问题。从20世纪70年代起开始实施以食盐加碘为主的综合防治措施,IDD病情逐年减轻,2000年实现了消除IDD阶段目标。为了解中小学生体内碘营养水平,评价碘盐加碘浓度,于2011年6月—2012年6月对吉林省吉林市10个县
The body of a series of obstacles caused by iodine deficiency are collectively referred to as Iodine deficiency (IDD), China is one of the countries seriously threatened by IDD. Iodine deficiency can cause mental retardation and lead to mild mental retardation, including mild motor neuropsychiatric dysplasia, mental damage and subclinical hypothyroidism, a serious impact on the quality of the population, hinder the development of social issues. With IDD being controlled, the monitoring of iodine nutrition status among various groups of people, especially primary and secondary students, has become a major issue. Since the 1970s, comprehensive prevention and treatment measures based on iodization of salt have been implemented. The incidence of IDD has been reduced year by year. In 2000, the goal of eliminating IDD was achieved. In order to understand the level of iodine nutrition in primary and secondary school students and to evaluate iodized salt and iodine concentration, from June 2011 to June 2012, 10 counties in Jilin City, Jilin Province
