人群中碘缺乏会导致甲状腺肿患病率增加，更重要的是，可能会增加该人群中智力缺陷的风险。国家健康和营养检查调查[NHANES I（1971-1974）和NHANES III（1988-1994）]测量了尿碘（UI）浓度。UI浓度是人群碘摄入充足性的指标。碘充足人群中的UI浓度中位数应大于10 μ g/dL，UI浓度小于5 μ g/dL的人群不应超过20%。NHANES I和NHANES III的中位UI浓度表明美国总体人群的碘摄入量充足，但1971-1974年（32.0 +/- 0.6 μ g/dL）和1988-1994年（14.5 +/- 0.3 μ g/dL）之间的中位浓度下降超过50%。低UI浓度（
Iodine deficiency in a population causes increased prevalence of goiter and, more importantly, may increase the risk for intellectual deficiency in that population. The National Health and Nutrition Examination Surveys [NHANES I (1971-1974) and (NHANES III (1988-1994)] measured urinary iodine (UI) concentrations. UI concentrations are an indicator of the adequacy of iodine intake for a population. The median UI concentrations in iodine-sufficient populations should be greater than 10 mu g/dL, and no more than 20% of the population should have UI concentrations less than 5 mu g/dL. Median UI concentrations from both NHANES I and NHANES III indicate adequate iodine intake for the overall U.S, population, but the median concentration decreased more than 50% between 1971-1974 (32.0 +/- 0.6 mu g/dL) and 1988-1994 (14.5 +/- 0.3 mu g/dL). Low UI concentrations (
