目的了解阿坝州若尔盖县碘缺乏病病情及全州13县居民碘营养水平及防治措施落实情况,评价干预措施的实施效果。方法病情监测:全省按人口比例概率抽样方法 (PPS)抽取了阿坝州若尔盖县班偌乡小学,随机抽查40名8~10岁学生B超法测定甲状腺容积,并定量测定这些学生家中食用盐的碘含量;在抽到的学生中,再随机抽取12名检测尿碘含量,并测算其家中居民日人均食盐摄入量;在抽中学校附近,选择3个乡,每个乡抽取孕妇和哺乳妇女各5人,采用砷铈催化分光光度方法 (WS/T 107-2006)测定尿碘含量;在抽中学校的所在村,按东、西、南、北、中各抽取1份饮用水水样,如为集中式供水地区,则采集2份末梢水样进行水碘测定。8~10岁儿童尿碘水平监测:在每个县,按东、西、南、北、中5个方位各随机抽取1个乡;在所抽取的每个乡各随机抽取1所村小学;在所抽取小学各随机抽检20名8~10岁儿童(男、女各半)的尿样,每县尿样100份。其余12个县开展8~10岁儿童尿碘水平监测。结果 8~10岁儿童甲状腺肿大率为7.25%、8~10岁儿童尿碘中位数156.2μg/L、居民合格碘盐食用率为100%、盐碘中位数为39.7 mg/kg、孕妇尿碘中位数为143.9μg/L、哺乳妇女尿碘中位数为155.8μg/L;其余12个县8~10岁儿童尿碘中位数为165.22μg/L。结论阿坝州以食盐加碘为主的防治碘缺乏病的综合防治措施成效明显,各项指标均保持在县级消除碘缺乏病目标水平内,为阿坝州持续巩固消除碘缺乏病奠定了基础。 Objective To understand the status of iodine deficiency disorders in Ruoergai County, Aba Prefecture and the status of iodine nutrition in 13 counties in Jeonju and the prevention and treatment measures, and to evaluate the implementation effect of intervention measures. Methods Disease surveillance: According to the Probability Sampling Method (PPS), the province selected Bajiao Township Primary School in Ruoergai County, Aba Prefecture. Thirty patients aged 8-10 years were randomly selected to measure thyroid volume by B-mode ultrasonography. Quantitative measurements of edible salt Of the iodine content; in the students were drawn, and then randomly selected 12 urinary iodine detection, and calculate the average daily household salt intake; in the vicinity of pumping schools, select three townships, each township, pregnant women and breast-feeding 5 women each, urinary iodine content was determined by arsenic and cerium catalytic spectrophotometry (WS / T 107-2006); in the villages where the schools were drawn, 1 drinking water sample was taken from east, west, south, north and center In the case of centralized water supply, two peripheral water samples are collected for water iodine determination. Urine iodine level monitoring for children aged 8 to 10: In each county, one township is randomly selected in each of the five orientations of East, West, South, North and North; one village primary school is randomly selected in each township; A total of 20 urine samples of 8 to 10 years old children (half male and half female) were randomly selected from primary schools. 100 urine samples were collected from each county. The remaining 12 counties to carry out monitoring of urinary iodine levels in children aged 8 to 10 years. Results The goiter rate was 7.25% in children aged 8-10 years and 156.2 μg / L in children aged 8-10 years. The acceptable iodine salt was 100%, the median salt iodine was 39.7 mg / kg, The median urinary iodine of pregnant women was 143.9μg / L, and the median urinary iodine of lactating women was 155.8μg / L. The median urinary iodine of children aged 8-10 years in the remaining 12 counties was 165.22μg / L. Conclusion The comprehensive prevention and cure measures of iodine deficiency disorders with salt iodization in Aba prefecture have achieved remarkable results. All indicators are within the target level of eliminating iodine deficiency disorders at county level, laying a solid foundation for continued consolidation and elimination of iodine deficiency disorders in Aba Prefecture.
