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。
Objective To understand the status of iodine deficiency disorders in Sichuan Province and the iodine nutrition status of residents and the control effect. Methods Twenty-one counties were selected in Sichuan Province. One county was randomly selected from each of the counties in east, west, south, north and south of China. Salt iodine was measured at production levels in each county. Salt iodine and water Iodine results, palpation of children aged 8 to 10 thyroid gland were measured in reproductive age women, pregnant women, lactating women and their infants and children of 8 to 10 years of salt and iodine in children at home to investigate children’s family meal salt intake the amount. Results The production quality of the batches reached 100% pass rate, the coverage of iodized salt in the sales points was 100%, the median of water iodine was 3.41μg / L, the coverage rate of iodized salt in the whole province was 99.96% and the consumption rate of qualified iodized salt was 96.42% , Urinary iodine median of 171.54,161.40,157.28,191.75 and 184.01μg / L respectively in childbearing age women, pregnant women, lactating women, infants and toddlers, children aged 8-10 years; average salt intake 8.04g / ·day). Conclusions Sichuan Province will continue to eliminate the status of iodine deficiency disorders. In the future, iodine deficiency disorders surveillance and health education will continue to be strengthened, especially for iodine nutrition monitoring in key populations.
