摘要
目的掌握重庆市居民食用碘盐质量和碘缺乏病病情变化。方法监测居民食用碘盐覆盖率和合格碘盐食用率；采用人口比例概率抽样法（PPS）进行抽样，用触诊法和B超法同时检查8～10岁儿童甲状腺肿大情况，儿童尿碘测定采用砷铈催化分光光度法。结果1997～2005年，碘盐覆盖率为90．08％～98．17％，合格碘盐食用率为83．00％～92．37％；儿童甲状腺肿大率触诊法由18．33％（220／1200）下降至10．45％（132／1263）．B超法由17．42％（209／1200）下降至9．90％（125／1263）；尿碘中位数稳定在238．75～266．65μg/L。结论重庆市普供碘盐8年来防治碘缺乏病的效果显著。
Objective In order to explore the quality of iodized salt and the change of iodine deficiency disorders, Methods The coverage rate of iodized salt and rate of consuming qualified iodine salt were monitored. Urinary iodine, thyroid volume of children aged 8 - 10 years by B-ultrasound and palpation were studied using population proportion probability sampling（PPS） method. Iodine content in urine was tested by arsenic-cerium catalytic spectrophotometry method. Results Universal salt iodization was conducted in Chongqing from 1997 to 2005, the eight- year coverage rates of iodine salt were 90.08% - 98.17%, and the rates of consuming qualified iodine salt ranged 83.00% - 92.37%; total goiter rates decreased from 18.33% （220/1200） to 10.45% （132/1263） by palpation, from 17.42% （209/1200） to 9.90% （125/1263） by B-ultrasound. The medians of urinary iodine stably kept from 238.75 to 266.65 μg/L. Conclusion Universal salt iodization exerts an effect on preventing iodine deficiency disorders for 8 years in Chongqing City.
