目的了解新疆生产建设兵团(简称兵团)碘盐普及情况和儿童尿碘水平状况,为制定碘缺乏病防治策略提供科学依据。方法在兵团14个师开展调查,所辖有9个以上团的师,按东西南北中5个方位采用单纯随机抽样方法抽取9个团,每个团随机抽取4个连队,每个连队随机抽检8户居民食用盐样进行碘含量检测;所辖有9个或不足9个团的师,抽取所有团,每个团随机抽取4个连队,每个连队随机抽取15户居民食用盐样进行碘含量检测;在每个被监测团随机抽取1所小学,在每所小学抽取20名8～10岁儿童尿样进行尿碘测定。结果共检测盐样4067份,盐碘含量均值为(33.61±5.34)mg/kg,中位数为32.20mg/kg,合格盐样4003份,不合格碘盐22份,非碘盐42份,碘盐覆盖率为98.97%,碘盐合格率99.45%,合格碘盐食用率为98.43%,非碘盐率为1.03%;共检测8～10岁儿童尿样3572份,尿碘中位数239.00μg/L,尿碘﹤50μg/L的占2.7%(95/3572),50～99.99μg/L的占7.4%(264/3572),100～199.99μg/L的占27.4%(977/3572),200～299.99μg/L的占31.2%(1116/3572),≥300μg/L的占31.4%(1120/3572)。结论当前的盐碘水平下,兵团各地儿童的碘营养状况基本处于良好和适宜水平,但也应因地制宜,根据当地人群碘营养水平适时调整盐碘,保证体内碘营养水平处于合理状态。
Objective To understand the prevalence of iodized salt in Xinjiang Production and Construction Corps (abbreviation: Corps) and the status of urinary iodine in children, and provide a scientific basis for the prevention and control of iodine deficiency disorders. Methods A total of 14 divisions were investigated in Corps. There were 9 divisions under the jurisdiction of divisions. Nine divisions were selected by simple random sampling method in five orientations of south, east and west. Four corps were randomly selected from each corps, and each corps was randomly selected 8 households inhaled salt samples for iodine detection; under the jurisdiction of 9 or less regiment division, draw all the groups, each group randomly selected 4 companies, each company randomly selected 15 households salt consumption of iodine for iodine The content of urine was detected. One primary school was randomly selected from each monitoring group, and urine samples from 20 children aged 8 to 10 were collected for urine iodine determination in each primary school. Results A total of 4067 salt samples were detected. The mean salt iodine content was (33.61 ± 5.34) mg / kg, the median was 32.20 mg / kg, the qualified salt samples were 4003, 22 unqualified iodized salts and 42 non- The coverage rate of iodized salt was 98.97%, the qualified rate of iodized salt was 99.45%, the rate of qualified iodized salt was 98.43% and the rate of non-iodized salt was 1.03%. The urine samples of 8 to 10 years old were 3572 and the urinary iodine median was 239.00 2.7% (95/3572) for urinary iodine <50μg / L, 7.4% (264/3572) for 50-99.99μg / L and 27.4% (977/3572) for 100-199.99μg / L ), 31.2% (1116/3572) at 200-299.99 μg / L and 31.4% (1120/3572) at ≥300 μg / L. Conclusions Under current salt and iodine levels, the iodine nutrition status of children in Corps is basically at a good and appropriate level. However, salt iodine should be properly adjusted according to local conditions and iodine nutrition of local people to ensure iodine nutrition in the body is in a reasonable state.
