The use of vitamin and mineral supplements is increasing among young individuals. We surveyed 972 Korean teenagers (age 13-18 y ) for their use of vitamin/mineral supplements, their motivational factors, and the dietary consequences of supplement use. Prevalence of vitamin/mineral supplement use was 31%. Supplement use was highest in high-school students, females, individuals living in rural communities, and individuals from families in high socioeconomic strata. The supplements used most frequently were vitamin C, multivitamins, and vitamin A. Supplement users had a more positive view of the potential health benefits of supplements than did non-users. Most supplements were taken daily. Vitamins B2, B6, and C were the most frequently ingested nutrients from vitamin/mineral supplements. Vitamin/mineral intakes from supplements had a wide range, with mean intakes typically exceeding Korean or the U.S./Canadian recommended dietary allowances. Vitamins B12, B1, and C and iron comprised 2770%, 1930%, 1120%, and 1026%, respectively, of the Korean recommended dietary allowances. When nutrient intakes from the diet and supplements were combined, intakes of niacin, vitamin C, and iron exceeded the recommended upper-intake levels for these nutrients. The health benefits and risks of supplement use by teenagers merits further study.
维生素和矿物质补充剂在年轻人中的使用正在增加。我们对972名韩国青少年（年龄在13 - 18岁）进行了调查，了解他们对维生素/矿物质补充剂的使用情况、使用动机以及补充剂使用对饮食的影响。维生素/矿物质补充剂的使用率为31%。高中生、女性、居住在农村社区的人以及来自高社会经济阶层家庭的人补充剂使用率最高。最常使用的补充剂是维生素C、多种维生素和维生素A。与非使用者相比，补充剂使用者对补充剂潜在健康益处的看法更为积极。大多数补充剂是每天服用。维生素B2、B6和C是从维生素/矿物质补充剂中最常摄入的营养素。从补充剂中摄入的维生素/矿物质含量范围很广，平均摄入量通常超过韩国或美国/加拿大的推荐膳食摄入量。维生素B12、B1、C和铁分别占韩国推荐膳食摄入量的2770%、1930%、1120%和1026%。当将饮食和补充剂中的营养素摄入量相加时，烟酸、维生素C和铁的摄入量超过了这些营养素的推荐上限摄入量。青少年使用补充剂的健康益处和风险值得进一步研究。
