目标.我们试图确定美国维生素C缺乏和消耗的患病率。我们使用第三次全国健康与营养调查的数据来评估膳食、补充剂和血清维生素C的摄入量。维生素C的平均摄入量和血清水平正常;然而，维生素C缺乏和消耗是常见的（分别发生在5%-17%和13%-23%的受访者中）。吸烟者，那些谁不使用补充剂，和非西班牙裔黑人男性维生素C缺乏症的风险升高，而墨西哥裔美国人的风险较低。卫生专业人员应建议食用富含维生素C的蔬菜和水果，并建议有维生素C缺乏风险的个人补充维生素C。
Objectives. We sought to determine prevalence rates of vitamin C deficiency and depletion in the United States.Methods. We used data from the Third National Health and Nutrition Examination Survey to assess intake of dietary, supplemental, and serum vitamin C.Results. Mean intakes and serum levels of vitamin C were normal; however, vitamin C deficiency and depletion were common (occurring among 5%-17% and 13%-23% of respondents, respectively). Smokers, those who did not use supplements, and non-Hispanic Black males had elevated risks of vitamin C deficiency, while Mexican Americans had lower risks.Conclusions. Health professionals should recommend consumption of vegetables and fruits rich in vitamin C and should recommend supplementation for individuals at risk of vitamin C deficiency.
