An Expert Panel on Vitamin A Nutriture assessed serum vitamin A values and related data collected during the first and second National Health and Nutrition Examination Surveys (NHANES I and NHANES II) and the southwest component of the Hispanic Health and Nutrition Examination Survey (SW HHANES). The appropriateness of the analytical methodologies and adequacy of the quality-control procedures used to obtain the serum vitamin A values were evaluated. Age-specific guidelines for the interpretation of serum vitamin A values in selected low ranges (less than 20, 20-24 and 25-29 micrograms/dl) were developed, and estimates of the prevalence of serum vitamin A values in these ranges were presented for each of the three surveys.
一个维生素A营养状况专家小组评估了在第一次和第二次全国健康与营养检查调查（NHANES I和NHANES II）以及西班牙裔健康与营养检查调查的西南部部分（SW HHANES）期间收集的血清维生素A值及相关数据。对用于获取血清维生素A值的分析方法的适宜性和质量控制程序的充分性进行了评估。制定了针对选定低范围（低于20、20 - 24和25 - 29微克/分升）血清维生素A值解释的年龄特异性指南，并给出了这三项调查中每个调查在这些范围内血清维生素A值患病率的估计。
