2015年四川省人群碘缺乏病现况调查

A Cross-Sectional Study on Iodine Deficiency Disorders in the General Population in Sichuan Province

目的掌握四川省碘缺乏病病情、居民碘营养状况和防治效果。方法在四川省选取21个县,每个县按东、西、南、北、中各随机抽取1个乡,测定各县生产层次的盐碘,测定每个乡碘盐销售点盐碘和水碘结果,触诊检查8~10岁儿童的甲状腺,分别测定育龄妇女、孕妇、哺乳期妇女及其婴幼儿和8~10岁儿童的家中盐碘和尿碘,调查儿童家庭就餐人员食盐摄入量。结果生产层次的批质量合格率为100%,销售点碘盐覆盖率均为100%,水碘中位数为3.41μg/L,全省碘盐覆盖率99.96%,合格碘盐食用率96.42%,育龄妇女、孕妇、哺乳期妇女、婴幼儿、和8~10岁儿童的尿碘中位数分别为171.54、161.40、157.28、191.75和184.01μg/L;平均食盐摄入量8.04 g/(人·天)。结论四川省继续保持消除碘缺乏病状态,今后将继续加强碘缺乏病监测、健康教育、特别是重点人群碘营养监测工作。

ObjectiveTo investigate the situation of iodine deficiency disorders （IDD）, the current status of iodine nutrition and the prevention and control effects in Sichuan Province. MethodsTwenty one counties were selected in Sichuan Province, in each county, one town was randomly drawn in the east, the west, the south, the north and the middle each to determine iodine in salt at the production level in different counties. Iodine in salt at each sales site of each town and water iodine were determined. Thyroids of kids aged between 8 to 10 years old were examined by palpation method ; iodine in salt of families of women of child - bearing potential, pregnant women, nursing mothers as well as iodine in urine of them and their infants and children aged between 8 to 10 years old were determined. Salt intakes of children eating at home were surveyed. ResultsThe batch quality conformity rate was 100% at the production level; the iodine salt coverage rate of each sales site was 100% ; the water iodine median was 3.41 μg/L; the iodine salt coverage rate of the whole province was 99.96% ; the qualified iodized - salt coverage rate was 96.42% ; the median urinary iodine levels of women of childbearing potential, pregnant women, nursing mothers, infants and children aged 8 to 10 years old children were 171.54, 161.40, 157.28, 191.75, 184.01 p,g/L, respectively; the average salt intake was 8.04 g/person· day. ConclusionThe eliminated state of iodine ince; more efforts will be taken in the future in terms deficiency disorders has been maintained in Sichuan province; more efforts will be taken in the future in terms of the iodine deficiency disorders surveillance, health education and surveillance of iodine nutrition in critical populations.
