Hotien prefecture, Xinjiang Province, China, in the Taklamakan Desert, is an area of severe iodine deficiency. Because usual methods of iodine supplementation failed here, we began supplementation in 1992 with potassium iodate, which was added to irrigation water (Lancet 1994; 334:107-110). We report 4 y experience with this method in 3 townships that contained a total treated population of 37,000. Potassium iodate was dripped into irrigation water (to a concentration 10-80 microg/l) during a 2- to 4-wk period. During the 3 y that followed, no further supplementation was made, and iodine concentrations increased several fold in crops and plants, sheep and chicken thyroid glands, and meat and in urine of children 2-6 y of age and of women who were of childbearing age. Infant mortality decreased 50%, and sheep production increased 43%. Iodine repletion of soil through irrigation water is an effective and cost-efficient way of providing iodine in appropriate situations.
中国新疆和田地区位于塔克拉玛干沙漠，是严重碘缺乏地区。由于常规补碘方法在此处未能奏效，我们于1992年开始采用碘酸钾进行补碘，其被添加到灌溉水中（《柳叶刀》1994年；334卷：107 - 110页）。我们报告了在3个乡采用此方法4年的经验，这些乡的总受治人口为37000人。在2至4周时段内将碘酸钾滴入灌溉水中（浓度为10 - 80微克/升）。在随后的3年里，未进行进一步补碘，作物和植物、绵羊和鸡的甲状腺、肉类以及2至6岁儿童和育龄妇女尿液中的碘浓度增加了数倍。婴儿死亡率降低了50%，绵羊产量增加了43%。通过灌溉水使土壤补碘在适当情况下是一种有效且经济高效的补碘方式。
