摘　　要：目的了解食盐加碘含量调整前后，淄博市育龄妇女、孕妇、哺乳期妇女和婴幼儿4类重点人群的碘营养水平变化情况，为碘缺乏病防治提供科学依据。方法2011年和2015年，采集淄博市7个碘缺乏县（区）的居民户食用盐盐样以及育龄妇女、孕妇、哺乳期妇女和婴幼儿尿样进行检测，对两年检测结果进行对比分析。结果2011年和2015年分别检测盐样2100、2160份．盐碘中位数分别为30．2、22．7mg／kg，两年盐碘水平构成比比较差异有统计学意义（x^2=141．90，P〈0．01）；2011年检测育龄妇女、孕妇、哺乳期妇女和婴幼儿4类重点人群的尿样354、402、403、362份，尿碘中位数分别为161．80、127．20、138．80和147．10μg／L；2015年检测4类人群的尿样350、706、350、352份，尿碘中位数分别为127．80、129．95、70．20和152．35μg／L。结论淄博市碘盐含量调整后．盐碘中位数有所降低，育龄妇女和婴幼儿尿碘中位数处于适宜状态，孕妇和哺乳期妇女尿碘中位数水平均不足，建议加强孕妇和哺乳期妇女的健康教育和饮食指导，让其有意识地通过食物或者碘制剂补碘．同时加强重点人群的碘营养状况监测。Objective To analyze the survey results of iodine nutritional level among women of childbearing age, pregnant, lactating women and infants before and after the adjustment of iodine concentration in salt of Zibo City, in order to provide a scientific basis for reasonable iodine supplement. Methods The iodine content in the residents＂ edible salt samples was determined in 2011 and 2015. Four groups of target populations including women of childbearing age, pregnant, lactating women and infants from 7 districts and towns of Zibo were investigated to test their urinary iodine level in 2011 and 2015. The monitoring results of the two years were compared and analyzed. Results A total of 2 100 and 2 160 residents edible salt were monitored in 2011 and 2015, and the median of salt iodine were 30.2 and 22.7 mg/kg, there was statistically significant difference in the constitute of salt iodine level between the two years （x^2 = 141.90, P 〈 0.01）. A total of 354, 402, 403, 362 urine samples of women of childbearing age, pregnant, lactating women and infants＂ were detected and the median urinary iodine were 161.80, 127.20, 138.80, 147.10 μg/L in 2011, and 350, 706, 350 and 352 of the corresponding target population＇s urine samples were detected and the median urinary iodine were 127.80, 129.95, 70.20 and 152.35 μg/L in 2015. Conclusions The salt iodine median has reduced and the urinary iodine in childbearing age women and infant is in the appropriate level, while it is insufficient in the pregnant women and lactating women after the adjustment of iodized salt concentration in Zibo. It is necessary to promote health education and instruct pregnant women and lactating women to supplement iodine, additionally, surveillance of the iodine nutrition status of the targeted populations should be strengthened.
