我国人群碘平衡研究资料较少。本研究旨在探讨中国健康女性碘的适宜营养素推荐摄入量（RNI）。对25名甲状腺功能正常的中国妇女进行了为期4周的研究。在两个不同时期提供不同碘含量的统一膳食，其中前3周给予非碘盐，随后1周给予碘盐。监测并测定了从膳食、水和空气中摄入的总碘量以及经尿、粪和呼吸排出的总碘量。还考虑了汗碘损失。建立了24 h碘摄入量与24 h碘排泄量的回归曲线模型。两个时期的24 h碘摄入量分别为194中心点8（sd 62中心点9）和487中心点1（sd 177中心点3）μ g/d。24小时碘排泄量分别为130中心点9（sd 39中心点5）和265中心点4（sd 71中心点8）μ g/d。两个时期的24 h碘摄入量和24 h排碘量差异均有显著性（均P
There is a dearth of data on the iodine balance studies of Chinese population. In the present study, we aimed to explore the appropriate recommended nutrient intake (RNI) of iodine based on healthy Chinese women. A 4-week study was conducted in twenty-five Chinese euthyroid women. Uniform diets with different iodine contents were provided in two different periods, in which non-iodised salt was given in the first 3 weeks, followed by 1 week of iodised salt administration. The total iodine intake from diet, water and air as well as the total iodine excretion through urine, faeces and respiration were monitored and determined. The sweat iodine loss was also considered. Moreover, the regression curve model was established between the 24 h iodine intake and 24 h iodine excretion. The 24 h iodine intake in the two periods was 194 center dot 8 (sd 62 center dot 9) and 487 center dot 1 (sd 177 center dot 3) mu g/d, respectively. The 24 h iodine excretion was 130 center dot 9 (sd 39 center dot 5) and 265 center dot 4 (sd 71 center dot 8) mu g/d, respectively. Both 24 h iodine intake and 24 h iodine excretion of the two periods were significantly different (all P
