目的掌握巴中市巴州区碘缺乏病病情、人群碘营养和防治措施落实现况,为综合评价防治成效和实施针对性的防治措施提供依据。方法 2015年,采用单纯随机抽样:在巴州区东、西、南、北和中5个方位各抽取1个乡(镇)作为调查点,在每个调查点中心小学抽取80名8~10岁儿童(年龄均衡、男女各半)开展甲状腺肿大情况调查,采集其中10人1次随机尿样检测尿碘同时采集其家中食用盐检测盐碘并调查其家庭日人均食盐摄入量;在每个调查点抽取40岁以下育龄妇女、孕妇、哺乳期妇女及其0~2岁婴幼儿各10人采集1次随机尿样检测尿碘同时采集其家中食用盐检测盐碘;在每个调查点抽取不相邻2个村,每村采集1份日常生活饮用水检测水碘并调查1个村级碘盐销售点情况;在供应巴州区碘盐的盐业公司仓库采集9份盐样(上下半年各1次)评价碘盐产品批次合格情况。结果甲状腺肿大率0.25%;尿碘中位数228.1μg/L,<50μg/L比例为0.8%;盐碘中位数29.1 mg/kg,碘盐覆盖率100%,合格碘盐食用率97%;水碘中位数6.3μg/L,范围(2.8~9.2)μg/L;居民家庭日人均食盐摄入量8.5 g;碘盐产品含碘量均值(24.96±2.16)mg/kg;碘盐销售点所售食用盐均为碘盐。结论巴州区自然环境普遍缺碘,防治措施得到有效落实,人群碘营养水平总体适宜并持续保持碘缺乏病消除状态。 Objective To understand the status of iodine deficiency disorders in Bazhou district of Bazhong, population iodine nutrition and the implementation status of prevention and treatment measures, so as to provide the basis for comprehensive evaluation of prevention and treatment results and implementation of targeted prevention and treatment measures. Methods In 2015, a simple random sampling method was adopted. One township (town) was sampled from each of the five orientations of East, West, South, North and Central of Bazhou. Eighty eight to ten Year-old children (equal age, half male and half female) to carry out the investigation of goiter, collected 10 of them random urine samples of 1 urine iodine detection at the same time collecting salt in their home to detect salt iodine and investigate their family daily average salt intake; At each survey point, 10 women of childbearing age, pregnant women, lactating women and their infants aged 0 ~ 2 years old were collected at random. One random urine sample was collected to detect urinary iodine. At the same time, Take 2 nonadjacent villages, collect 1 daily drinking water in each village to test water iodine and investigate 1 village iodized salt point-of-sale; collect 9 salt samples from the salt industry warehouse that supplies iodized salt in Bazhou District (1 in the second half of the year) Evaluation of qualified iodized salt product batch. Results The median of urinary iodine was 228.1 μg / L and the ratio of <50 μg / L was 0.8%. The median of salt iodine was 29.1 mg / kg, the coverage of iodized salt was 100% and the consumption of qualified iodized salt was 97% %; The median of water iodine 6.3μg / L, the range of (2.8 ~ 9.2) μg / L; average daily household salt intake of 8.5 g; iodine salt products iodine average value (24.96 ± 2.16) mg / Salt sold at the sale of salt are iodized salt. Conclusions The natural environment in Bazhou district is generally iodine deficiency, and the prevention and control measures are effectively implemented. The iodine nutrition level of the population is generally suitable and the state of iodine deficiency deficiency elimination is maintained.
