【摘要】：目的为进一步了解西藏碘缺乏病病情、居民碘营养水平及防治措施落实情况,巩固和完善西藏碘缺乏病长效防控机制。方法采用随机抽样法,按照按照人口比例概率抽样(PPS),在全区抽取30个县开展碘缺乏病病情监测,从抽取到的县(市、区)中抽取1个乡(镇)的1所小学,每所小学随机抽查50名8-10岁学生的甲状腺容积和尿样,在每个被抽取的小学所在地的乡(镇)采集20名孕妇尿样;采用砷铈催化分光光度方法(WS/T 107-2006)测定尿碘;采用B超法检查甲状腺容积,并按地方性甲状腺肿的诊断标准(WS 276-2007)判定;采集儿童家中食用盐,用硫代硫酸钠直接滴定法(GB/T 13025.7-2012)测定。结果 B超检查8-10岁儿童甲状腺1 272人次,肿大率为2.7%(34/1 272);检测盐样1 200份,盐碘中位数为26.6 mg/kg,合格碘盐食用率为73.1%(877/1 200);检测8-10岁儿童和孕妇尿样1 534份和565份,尿碘中位数分别为140.0μg/L、129.2μg/L。结论食盐加碘含量调整后,西藏自治区8-10岁儿童碘营养总体处于适宜水平,但部分地区(阿里、那曲)碘盐覆盖率偏低,部分地区(日喀则市)孕妇碘营养缺乏,全区合格碘盐食用率较低,应监管好碘盐配送工作,并加强生产层次碘盐碘含量的检测工作,同时应积极推进目标人群的健康教育促进工作。
[Abstract]:Objective to further understand the condition of iodine deficiency disorders (IDD) in Tibet, the iodine nutrition level of residents and the implementation of prevention and control measures, and to consolidate and improve the long-term prevention and control mechanism of IDD in Tibet. According to the population proportional probability sampling (PPSG), 30 counties in the whole district were selected to carry out IDD disease surveillance, and 1 primary school in one township (town) was extracted from the selected counties (cities, districts). The thyroid volume and urine samples of 50 pupils aged 8 to 10 years were randomly selected from each primary school. Urine samples were collected from 20 pregnant women in the township (town) of each selected primary school, and urine iodine was determined by arsenic and cerium catalytic spectrophotometry (WSP / T 107-2006). Thyroid volume was examined by B-ultrasonic method and judged according to the diagnostic criteria of endemic goiter WS276-2007.The salt in children's home was collected and measured by direct titration of sodium thiosulfate (GBT / 13025.7-2012). Results the thyroid gland of children aged 8-10 years was examined by B-ultrasound. The swelling rate was 2.734 / 1272%, 1 200 salt samples were detected, the median salt iodine was 26.6 mg / kg, the qualified iodized salt consumption rate was 73.1% 877 / 1 200, the urine samples of children and pregnant women aged 8 to 10 years were 1 534 and 565, the median urinary iodine was 140.0 渭 g / L ~ (-1) 渭 g / L ~ (129.2) 渭 g 路L ~ (-1) 路L ~ (-1). The iodine nutrition of children aged 8 to 10 years in Tibet Autonomous region is generally at the appropriate level, but the iodized salt coverage in some areas (Ali, Naqu) is on the low side, and in some areas (Xigaze City), the iodine nutrition of pregnant women is deficient, and the consumption rate of qualified iodized salt in the whole region is relatively low. It is necessary to supervise the distribution of iodized salt and strengthen the measurement of iodized salt content in production level. At the same time, we should actively promote the health education of the target population.
