目的:了解桐乡市碘缺乏病通过阶段目标评估后的监测结果,探讨可持续消除碘缺乏病工作机制。方法:每年对居民户进行碘盐抽样监测,随机抽取9个镇(街道),36个行政村,每村随机抽取8户居民盐样;定向对蔬菜加工区17户居民家中的食用盐半定量监测,每年1~2次;在全市范围内按东西南北中每年抽取5所镇(街道)中心小学,对8~10岁在校学生进行甲状腺肿大率(触诊法或B超法)、尿碘水平监测。结果:8年来桐乡市居民合格碘盐食用率平均为91.55%。8~10岁儿童甲状腺肿大率触诊法平均为4.43%,B超法平均为8.16%,尿碘算术均数为194.47μg/L,中位数为196.10μg/L,100~200μg/L的占38.13%,>200μg/L的占47.49%。结论:桐乡市居民已为足量碘摄入,且处于安全碘摄入量范围。但蔬菜加工区碘盐覆盖率及合格碘盐食用率仍然偏低。因此,在不断开展健教的基础上,批发非碘盐腌制蔬菜时搭配“口粮”碘盐,是克服这一难点的根本措施。
OBJECTIVE: To understand the monitoring results of phase I target assessment of iodine deficiency disorders in Tongxiang City and to explore the working mechanism of sustainable elimination of iodine deficiency disorders. Methods: The sample of iodized salt was monitored annually by residents. Nine towns (streets) and 36 administrative villages were randomly selected. Eight villages were randomly sampled from each village for salt samples. Semi-quantitative analysis of edible salt in 17 households in vegetable processing area was conducted. Monitoring every year, 1 or 2 times a year; according to the east, west, north and south, 5 towns (streets) Central Primary Schools are drawn every year, goiter rate (palpation or B-mode) Urine iodine level monitoring. Results: The average eating rate of qualified iodized salt in Tongxiang City in the past 8 years was 91.55%. The average thyroid gland palpation rate was 4.43% in children aged 8 ~ 10 years, 8.16% in B-ultrasound method, 194.47μg / L in urinary iodine, the median was 196.10μg / L and 100 ~ 200μg / L Accounted for 38.13%,> 200μg / L accounted for 47.49%. Conclusion: Tongxiang residents have sufficient iodine intake and are in safe iodine intake range. However, the coverage of iodized salt in vegetable processing areas and the consumption of qualified iodized salt are still low. Therefore, based on the continuous development of health education, it is a fundamental measure to overcome this difficulty to match the “rations” iodized salt in the non-salted vegetables.
