A multivitamin/mineral supplement is the most widely used type of dietary supplement among American adults. Therefore, accurate assessment of intake from this supplement is crucial when studying diet and chronic diseases. From 1999 to 2001, the Multiethnic Cohort Study collected detailed information on multivitamin/mineral use among five ethnic groups: African Americans, Native Hawaiians, Japanese Americans, Latinos, and whites. Daily nutrient intakes from multivitamin/minerals were calculated using the nutrient composition specified on the product label. For reported supplements with insufficient detail to match to a specific product, default nutrient profiles were assigned. Multivitamin/mineral use was reported by 50% of the participants (38% for Native Hawaiians to 57% for whites). Default profiles were assigned for 38% of users. The median daily nutrient intakes from multivitamin/minerals among users (n=75,865) were well above the Recommended Daily Allowance or Adequate Intake for vitamins A, B-6, B-12, and E, thiamin, riboflavin, niacin, pantothenic acid, folate, and zinc. Although nutrient intakes from multivitamin/minerals varied widely among individuals, there was no substantial difference in the median intake across ethnic groups. To accurately estimate nutrient intakes from multivitamin/minerals, detailed information on the product consumed should be collected. When detailed information is not available, the same default nutrient profiles can be used when estimating intakes for these five ethnic groups.
多种维生素/矿物质补充剂是美国成年人中使用最广泛的膳食补充剂类型。因此，在研究饮食与慢性病时，准确评估该补充剂的摄入量至关重要。1999年至2001年，多民族队列研究收集了五个种族群体（非裔美国人、夏威夷原住民、日裔美国人、拉丁裔和白人）使用多种维生素/矿物质的详细信息。根据产品标签上规定的营养成分计算多种维生素/矿物质的每日营养素摄入量。对于报告细节不足无法匹配特定产品的补充剂，指定默认营养概况。50%的参与者报告使用了多种维生素/矿物质（夏威夷原住民为38%，白人为57%）。38%的使用者被指定了默认概况。使用者（n = 75,865）从多种维生素/矿物质中摄入的每日营养素中位数远高于维生素A、B - 6、B - 12、E、硫胺素、核黄素、烟酸、泛酸、叶酸和锌的推荐每日摄入量或适宜摄入量。尽管个体从多种维生素/矿物质中摄入的营养素差异很大，但不同种族群体的摄入量中位数没有实质性差异。为了准确估计从多种维生素/矿物质中摄入的营养素，应收集所食用产品的详细信息。当没有详细信息时，在估计这五个种族群体的摄入量时可以使用相同的默认营养概况。
