本文介绍了国家营养监测系统目前提供的信息，这些信息与评估美国人口群体的维生素D状况有关，这些信息的优势和局限性，以及维生素D营养状况评估的选定结果。全国健康和营养检查调查（NHANES）仅提供了1988年至1994年维生素D摄入量的信息。NHANES收集了从1988年到目前调查的补充剂使用和循环25-羟基维生素D [25（OH）D]浓度的信息。2002年，国家营养素标准参考数据库开始提供关于食物中维生素D含量的有限数据，并继续更新这些数据。食品标签和包装调查提供了2006-2007年市售食品维生素D强化的标签信息。尽管现有数据的局限性和关于评估人群中维生素D状况的适当标准的争议，我们可以对生命阶段组之间的维生素D状况进行一些有用的比较。一般来说，男性的维生素D摄入量和25（OH）D浓度高于女性。儿童的维生素D水平往往高于成人。在年轻人到老年人中越来越多地使用多种维生素-矿物质膳食补充剂与血清25（OH）D浓度的相应增加无关。一般来说，较瘦的人比较重的人有更高的25（OH）D循环浓度和补充使用。最后，非西班牙裔白人的维生素D水平往往高于非西班牙裔黑人和墨西哥裔美国人。
This article describes the information currently available in the National Nutrition Monitoring System that is relevant to assessing the vitamin D status of US population groups, the strengths and limitations of this information, and selected results of vitamin D nutritional status assessments. The National Health and Nutrition Examination Survey (NHANES) provides information on vitamin D intakes only from 1988 to 1994. NHANES collected information on supplement use and circulating 25-hydroxyvitamin D [25(OH)D] concentrations from 1988 through current surveys. The National Nutrient Database for Standard Reference started providing limited data on the vitamin D content of foods in 2002 and continues to update these values. The Food Label and Package Survey provides 2006-2007 label information on vitamin D fortification of marketed foods. Despite limitations in the available data and controversies about appropriate criteria for evaluating vitamin D status among population groups, we can make some useful comparisons of vitamin D status among life-stage groups. In general, males have higher vitamin D intakes and 25(OH)D concentrations than do females. Children tend to have higher vitamin D status than adults. The increasing use of multivitamin-mineral dietary supplements in younger to older adults is not associated with a corresponding increase in serum 25(OH)D concentrations. In general, leaner individuals have higher circulating concentrations of 25(OH)D and supplement use than do heavier individuals. Finally, non-Hispanic whites tend to have higher vitamin D status than do non-Hispanic blacks and Mexican Americans.
