摘要
目的了解陕西省宝鸡市碘缺乏病防治现状。方法2009—2011年，按照《全国碘盐监测方案》在宝鸡市12个县（区）开展碘盐监测、儿童甲状腺触诊调查。调查按照农村、城市分层进行，每个县（区）按层各抽取8～10岁儿童60名，采集尿样测定尿碘。2011年，在采集儿童尿样的家中，采用“三日称量法”进行人均日摄盐量调查；选取代表宝鸡不同地貌特征的陈仓区、扶风县、太白县进行水碘和孕妇、哺乳期妇女尿碘调查，每个县（区）各抽查15人。尿碘和水碘测定采用砷铈分光光度法。结果2009—2011年，12个县（区）碘盐覆盖率均为100．00％（3468／3468），碘盐合格率、合格碘盐食用率均〉99．00％。儿童甲状腺肿大率依次为3141％（87／2548）、3．06％（77／2520）、3．33％（84／2520），均〈5％的国家标准。2009—2011年，8—10岁儿童尿碘中位数依次为368．20、293．80、332．50μg／L，尿碘≥300μg／L比例依次占到了66．42％（797／1200）、48．05％（692／1440）、56．67％（816／1440）。2011年，孕妇尿碘中位数为301．81μg／L，哺乳期妇女尿碘中位数为329．79μg／L；共调查1116户家庭，人均日盐摄入量中位数是8．9g；采集水源水样18份，水碘为0．60～10．25μg／L。结论宝鸡市人群碘营养总体上超出适宜水平．现行碘盐浓度有下调的空间，但要充分考虑不同缺碘地区和不同人群碘需求的差别。
Objective To learn the control status of iodine deficiency disorders in Baoji City of Shaanxi Province. Methods From 2009 to 2011, according to the ＂National Iodized Salt Monitoring Program＂, the iodized salt was monitored, and thyroid was examined in 12 counties（areas） of Baoji City. According to rural and urban area stratification, 60 children aged 8 to 10 were selected in each county（district）, and their urine samples were collected for determination of iodine content. In 2011, per capita daily salt intake was surveyed by the ＂three weighing method＂ at children＇s home whose urine was collected. Chencang Area, Fufeng County and Taibai County, representatives of Baoji City different geomorphic features were selected for investigation of water iodine, and urinary iodine of pregnant and lactating women, and 15 people were selected in each county （district）. Results From 2009 - 2011, in the 12 counties（areas） in Baoji City, the coverage rate of iodized salt was all 100.00% （3468/3468）; the qualified rate of iodized salt and the consumption rate of qualified iodized salt were all 〉 99.00%. Children＇s goiter rate was 3.41%（87/2548）, 3.06%（77/2520） and 3.33%（84/2520）, and they were all less than that of the national standard （ 〈 5% ）. Medians of urinary iodine of 8 - 10 years old children were 368.20, 293.80 and 332.50 μg/L, respectively, and the ratios of urine iodine ≥300 μg/L were accounted for 66.42% （797/1200）, 48.05%（692/1440） and 56.67%（816/1440）, respectively. Median urinary iodine of pregnant women was 301.81 μg/L and lactating women was 329.79 μg/L. A total of 1116 households were investigated, the median of ＂per capita daily salt intake＂ was 8.9 g. Eighteen water samples were collected, range of water iodine value were 0.60 - 10.25 μg/L. Conclusions Iodine nutrition in general population of Baoji City is exceeded the optimum level, and the current iodized salt concentration has some down space, but fully consideration should be taken on iodine needs in different iodine deficiency areas and among different groups of people.
