[摘要] 目的 调查强化碘盐对慈北地区甲状腺疾病流行病学的影响。方法 比较慈北地区居民强化碘盐前后碘摄入量、甲亢及其他甲状腺疾病的发病率。结果 强化碘盐前，慈北地区居民碘摄入量平均数为每日(64.9±5.7)μg/L；强化碘盐后，碘摄入量平均数增加至(135.6±6.7)μg/L，强化碘盐前后比较差异有统计学意义(P<0.05)。强化碘盐前后慈北地区居民甲亢发病情况及其他甲状腺疾病发病情况比较，差异均有统计学意义(P<0.05)。结论 慈北地区的碘缺乏病在2006～2010年得到了很好的控制，人群碘营养水平也比较适宜。碘强化时还要特别注意孕妇、母乳中的碘含量。为保障下一代的脑发育和人口素质，必须对碘缺乏地区居民实行碘盐强化，但各地区至少也要建立一个非碘盐销售点，以满足不宜吃碘盐患者的需要。

[Abstract] Objective To investigate the epidemiological impact of iodized salt on thyroid disease in Cibei area. Methods Compared the incidence of hyperthyroidism and other thyroid diseases of residents from Cibei area before and after strengthened iodine salt. Results Before strengthened iodized salt，iodine intake in residents was average of(64.9±5.7)μg/L daily；After strengthened iodine salt，average iodine intake increased to (135.6±6.7)μg/L and the differences of the two groups were significant(P<0.05). Conclusion Iodine deficiency disorders in Cibei area of 2006 to 2010 is a very good control，and iodine nutrition level is more appropriate. During the enhancement of iodized salt，it should pay special attention to iodine content in breast milk and pregnant women. To protect the next generation of brain development and the quality of the population，it must be imposed on residents in iodine deficiency areas enhancement of iodized salt，but the region also has to built up at least one non-iodized salt sales point to meet the needs of patients who should not eat iodized salt.

众所周知，缺碘会引起甲状腺疾病[1]。为了预防缺碘对我国人口造成的危害，2005年慈北地区开始实施全民食盐加碘。为调查强化碘盐对慈北地区甲状腺疾病流行病学的影响，本文分别对2005年前后慈北地区的甲状腺疾病发病情况进行抽样调查，调查内容包括食盐加碘前后慈北地区居民的碘摄入情况，甲状腺疾病发病情况、特点、变化趋势和转归，目的是寻找消除碘缺乏病的措施，为建立科学的防治机制提供依据，现报道如下。
1 资料与方法
1.1 一般资料
2000～2005年我们曾对慈北地区10000名居民的碘摄入情况和甲状腺流行病学进行过调查 ......
