目的掌握碘缺乏病重点人群碘营养现状,为地方病防治提供依据。方法在每个县东、西、南、北、中5个方位各随机抽取1个病区乡(不足5个时全部抽取),在所抽取的每个乡各随机抽取1所村小学(无村小学时,抽取乡中心小学);在所抽取小学各随机抽检40名8岁~10岁儿童(男、女各半)的尿样,并检查儿童甲状腺肿大情况。在所抽取的每个乡各随机抽检20名孕妇的尿样进行尿碘检验。在所抽取的每个乡随机抽取20户居民家中食盐样品,定量检测盐碘含量。结果 8岁~10岁儿童、孕妇尿碘中位数分别为226.7μg/L、154.1μg/L。非碘盐率为0.6%,合格碘盐食用率为95.2%。9个旗县区8岁~10岁儿童甲状腺肿大率均在5%以下。结论尿碘中位数和盐碘指标及甲状腺肿大率均达到国家标准范围,完全符合十二五规划碘缺乏病防治目标。
Objective To understand the status of iodine nutrition in key population of iodine deficiency disorders and provide basis for prevention and control of endemic diseases. Methods We randomly selected 1 ward township (less than 5 in total) in each of the five directions of east, west, south, north and south of each county, and randomly selected one village primary school Village primary school, the township primary school); in the primary school were selected 40 random sampling of 8-year-old to 10-year-old children (male and female half) of urine samples, and check the child’s goiter. Urine samples of 20 pregnant women were randomly selected for urine iodine test in each of the townships sampled. Salt samples were taken from 20 households in each village randomly selected for salt iodine quantification. Results The median urinary iodine of pregnant women from 8 years old to 10 years old was 226.7 μg / L and 154.1 μg / L, respectively. Non-iodized salt rate was 0.6%, qualified iodized salt rate was 95.2%. Goat nine districts of 8 years old to 10-year-old children with goiter rate below 5%. Conclusions The median urinary iodine, salt iodine index and goiter rate reached the national standard, in full compliance with the 12th Five-Year Plan for the prevention and treatment of iodine deficiency disorders.
