目的了解新疆生产建设兵团(简称兵团)食用盐碘含量调整前的碘盐水平与3类重点人群(8~10岁儿童、孕妇、哺乳期妇女)的碘营养状况,为今后评估调整效果提供依据。方法按《全国碘缺乏病监测方案》要求,结合兵团实际情况,采用“人口比例概率抽样方法”(PPS)抽取30个团场,每个团场按整群随机抽样方法抽取1所小学,在被抽到的小学随机抽取40名8~10岁儿童,检测其家中食用盐碘含量;从被抽到的40名儿童中再随机抽取12名(男、女各半),采集并检测尿碘含量;在抽中的学校所在地随机抽取孕妇和哺乳期妇女各15人检测尿碘含量。盐碘测定采用直接滴定法;尿碘测定采用砷铈催化分光光度法。结果共检测1 195份盐样,盐碘含量均值为(30.91±6.99)mg/kg,其中碘盐1 165份,合格碘盐1 148份,不合格碘盐17份,非碘盐30份,碘盐覆盖率为97.49%,碘盐合格率98.54%,合格碘盐食用率为96.07%。407名8~10岁儿童尿碘中位数为235.31μg/L,北疆地区8~10岁儿童尿碘中位数高于南疆地区儿童。386名孕妇尿碘中位数为182.99μg/L;432名哺乳期妇女尿碘水平为173.81μg/L,均达到WHO推荐的标准。结论现有的碘盐浓度下兵团居民碘营养水平基本适宜,兵团碘盐和儿童、孕妇、哺乳期妇女碘营养状况都已达到国家消除碘缺乏病阶段目标要求。
Objective To understand the status of iodine salt in iodized salt before the adjustment of iodine content in edible salt in Xinjiang Production and Construction Corps (abbreviated as Corps) and the iodine nutrition status of three key groups (children aged 8-10 years, pregnant women and lactating women) to provide basis for future assessment and adjustment . Methods According to the requirements of “National Monitoring Program for Iodine Deficiency Disorders” and the actual situation of Corps, 30 community fields were sampled using “Probability of Population Probability Sampling Method” (PPS), and each community was sampled by cluster random sampling method to select one primary school 40 children aged 8 to 10 years old were randomly selected from primary schools to detect the iodine content in their families. Twelve (male and female half) children were randomly selected from the 40 children who were taken to collect and test Urinary iodine content; randomly selected in the pumping school of pregnant women and lactating women were 15 to detect urinary iodine content. Salt iodine determination using direct titration; urinary iodine determination using arsenic cerium catalytic spectrophotometry. Results A total of 1 195 salt samples were detected. The mean salt iodine content was (30.91 ± 6.99) mg / kg, of which 1 165 were iodized salt, 1 148 qualified iodized salt, 17 unqualified iodized salt and 30 non-iodized salt. The coverage rate of iodized salt was 97.49%, the qualified rate of iodized salt was 98.54%, and the eating rate of qualified iodized salt was 96.07%. The median urinary iodine of 407 children aged 8-10 years old was 235.31 μg / L. The median urinary iodine of children aged 8-10 years in northern Xinjiang was higher than that of children in southern Xinjiang. The urinary iodine median of 386 pregnant women was 182.99μg / L; the urine iodine level of 432 lactating women was 173.81μg / L, which reached the WHO recommended standards. Conclusions The current iodine salt concentration is basically suitable for the iodine nutrition of the soldiers in the Corps. The iodine nutrition of the Corps iodized salt, children, pregnant women and breast-feeding women has reached the national goal of eliminating iodine deficiency deficiency stage.
