摘要
目的 探讨调整食盐加碘浓度的操作程序。方法 对妊娠和哺乳妇女、12岁以上及成人、6—12岁学龄儿童和0—6岁婴幼儿的尿碘、每天食盐食用量和食盐之碘含量在同一时间进行测定。结果 妊娠及哺乳妇女、12岁以上及成人、6—12岁儿童和6岁以下人群尿碘中位数分别为232.5、351.4、295.7μg/L和261.6μg/L;推算的碘摄入量分别为348.8、473.1、295.7μg/d和130.8μg/d;食盐食用量分别为11.0、10.2、9.9g/d和3.7g/d;食盐碘含量平均为28.4mg/kg;食盐供给的碘量分别是248.2、231.7、223.3μg/d和84.4μg/d;环境碘来源分别是151.0、283.5、123.5μg/d和79.4μg/d。食盐加碘量(mg/kg)=(200μg/d×1.4-环境碘来源)/(食盐食用量g/d×0.9×0.8)。结论 食盐加碘量应以WHO推荐的妊娠及哺乳妇女碘摄入量为基准,并根据环境碘来源和食盐食用量之变化进行调整。
Objective To discuss the operation sequence of adjustment in the amount of iodine to salt. Methods Urinary iodine excretion, daily intake salt, and iodine concentration in salt determines simultaneously in pregnant and lactating women, aged over 12, aged 6 to 12 , and aged 0 to 6 . Results Median urinary iodine was respectively 232.5 , 351.4 , 295.7 μg/Land 261.6 μg/L; Calculating intake of iodine was respectively 348.8, 473.1, 295.7 μg/d and 130.8 μg/d; Daily intake of salt was respectively 11.0 , 10.2, 9.9 g/d and 3.7 g/d; Iodine concentration in salt is 28.4 mg/kg; Daily iodine intake of salt was respectively 248.2 , 231.7, 223.3μg/d and 84.4 μg/d; Environment iodine sources was respectively 151.0, 283.5,123.5 μg/d and 79.4 μg/d in pregnancy and lactation, aged over 12, aged 6 to 12, and aged 0 to 6. Amount of iodine added to salt(mg/kg) = (200μg/d ×1.4 - environment iodine sources μg/d)/( intake of salt g/d ×0.9 × 0.8). Conclusions The amount of iodine added to salt should be based on recommended intakes of iodine for pregnancy and lactating, and be adjusted subsequently to reflect any changes in amount of salt ingested.
