- 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 g/L in 19711974) and NHANES III (145 3 g/L in 19881994). This report presents data from NHANES 20012002 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 20012002 was found to be 167.8 g/L (95% confidence interval [CI] 159.3177.6). The NHANES 20012002 data confirm the current stability of the U.S. iodine intake and continued adequate iodine nutrition for the country.
