Data from the second United States Health and Nutrition Examination Survey (NHANES II) suggest that almost 35 per cent of the US population 18 to 74 years of age takes vitamin/mineral supplements regularly. Both higher nutrient intake and use of vitamin supplementation are associated with older ages, higher income, higher education level, and White race. Accounting for differences associated with sex, age, race, income, and education, persons with higher nutrient intakes remain more likely to take vitamin supplements.
来自美国第二次健康与营养检查调查(NHANES II)的数据表明,美国18至74岁的人口中,近35%的人经常服用维生素/矿物质补充剂。较高的营养素摄入量和维生素补充剂的使用都与年龄较大、收入较高、教育水平较高以及白人种族有关。在考虑到与性别、年龄、种族、收入和教育相关的差异后,营养素摄入量较高的人仍然更有可能服用维生素补充剂。
