Abstract

Urine iodine has been measured in the U.S. population by the National Health and Nutrition Examination Survey (NHANES) since 1971. A downward trend was noted between NHANES I (320 +/- 6 microg/L in 1971-1974) and NHANES III (145 +/- 3 microg/L in 1988-1994). This report presents data from NHANES 2001-2002 that indicates that the U.S. median urine iodine (UI) level has stabilized since the initial drop between NHANES I and NHANES III. The median UI concentration in the U.S. population in NHANES 2001-2002 was found to be 167.8 microg/L (95% confidence interval [CI] 159.3-177.6). The NHANES 2001-2002 data confirm the current stability of the U.S. iodine intake and continued adequate iodine nutrition for the country.

摘要

自1971年以来，美国国家健康与营养检查调查（NHANES）一直在对美国人群的尿碘进行测量。在第一次全国健康和营养检查调查（NHANES I，1971 - 1974年为320±6微克/升）和第三次全国健康和营养检查调查（NHANES III，1988 - 1994年为145±3微克/升）期间，观察到尿碘水平呈下降趋势。本报告展示了2001 - 2002年全国健康和营养检查调查的数据，这些数据表明，自第一次全国健康和营养检查调查与第三次全国健康和营养检查调查之间出现最初下降以来，美国尿碘（UI）中位数水平已趋于稳定。2001 - 2002年全国健康和营养检查调查中，美国人群的尿碘浓度中位数为167.8微克/升（95%置信区间[CI] 159.3 - 177.6）。2001 - 2002年全国健康和营养检查调查的数据证实了美国目前碘摄入量的稳定性以及该国持续充足的碘营养状况。
