【摘要】：目的為進(jìn)一步了解西藏碘缺乏病病情、居民碘營養(yǎng)水平及防治措施落實(shí)情況,鞏固和完善西藏碘缺乏病長效防控機(jī)制。方法采用隨機(jī)抽樣法,按照按照人口比例概率抽樣(PPS),在全區(qū)抽取30個(gè)縣開展碘缺乏病病情監(jiān)測,從抽取到的縣(市、區(qū))中抽取1個(gè)鄉(xiāng)(鎮(zhèn))的1所小學(xué),每所小學(xué)隨機(jī)抽查50名8-10歲學(xué)生的甲狀腺容積和尿樣,在每個(gè)被抽取的小學(xué)所在地的鄉(xiāng)(鎮(zhèn))采集20名孕婦尿樣;采用砷鈰催化分光光度方法(WS/T 107-2006)測定尿碘;采用B超法檢查甲狀腺容積,并按地方性甲狀腺腫的診斷標(biāo)準(zhǔn)(WS 276-2007)判定;采集兒童家中食用鹽,用硫代硫酸鈉直接滴定法(GB/T 13025.7-2012)測定。結(jié)果 B超檢查8-10歲兒童甲狀腺1 272人次,腫大率為2.7%(34/1 272);檢測鹽樣1 200份,鹽碘中位數(shù)為26.6 mg/kg,合格碘鹽食用率為73.1%(877/1 200);檢測8-10歲兒童和孕婦尿樣1 534份和565份,尿碘中位數(shù)分別為140.0μg/L、129.2μg/L。結(jié)論食鹽加碘含量調(diào)整后,西藏自治區(qū)8-10歲兒童碘營養(yǎng)總體處于適宜水平,但部分地區(qū)(阿里、那曲)碘鹽覆蓋率偏低,部分地區(qū)(日喀則市)孕婦碘營養(yǎng)缺乏,全區(qū)合格碘鹽食用率較低,應(yīng)監(jiān)管好碘鹽配送工作,并加強(qiáng)生產(chǎn)層次碘鹽碘含量的檢測工作,同時(shí)應(yīng)積極推進(jìn)目標(biāo)人群的健康教育促進(jìn)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.
